Re: [android-developers] Re: Android shared preferences assignments not persisting between emulator sessions

[Kostya Vasilyev]

Robert,

Do you start the emulator with "Wipe data" option, by any chance?

If you are, that explains it, as wiping the data means well, wiping 
the data.


The preferences are stored in the file system of the emulated Android 
device, just like on a real phone, not directly within the host 
computer's file system.


You can find the files under:

/data/data//shared_prefs

Why do you need to control the file name?

Where SHARED_PREFS_FILENAME is a private final static string and

I added a test that retrieves the recently committed string and when I
check it (s2) the value is fine. So I am not having any problems with
shared preferences storage during the lifetime of my app. However,
when I relaunch the application in the emulator the shared preferences
storage area is empty and I can't find the values I stored in the last
emulator session. I did some reading and as far as I can see the
stored values should persist across sessions, apparently they are
saved in an XML file belonging to the emulator. Yet I am having
problems.

Can anyone tell me why my shared preferences storage values are not
persisting between Android emulator sessions?

Hi Community I am using smack for a chatting module in my application …

Now there is need to handle the multi chat screens.

Right now I am opening my chat screen activity as below

Intent chatIntent=new Intent(HomeActivity.this,ChatActivity.class);

startActivity(chatIntent);

When a user press back button/receive call/other function to that away
him/her from current screen >There I need to handle the activity GUI with
data..

What should I do for this ?

Is there other way I can user other View else start to new activity for chat

Re: [android-developers] Re: java

[luiX_]

Well, I think C# and Java are quite similar, maybe I would start by doing
some examples in pure Java (J2SE) just to feel comfortable with the syntax
and then try following some Android examples.

You could also tru monodroid if you want to develop just one particular app
:)

Good luck!

I think (as in "I'm not sure at all" xD) it's for saving memory, I mean:

[android-developers] ListActivity Memory leak with onConfigurationChanged

[Taf]

Hi,

I'm using a ListActivity, with onConfigurationChanged. I'm doing this
because I don't want onCreate to be called so i don't have to reload
data in the list view every time I change orientation.

I've found that when I call setListAdapter in the onCreate method of
my ListActivity , after a Number of orientation changes I get an out
of memory error. If I don't set the ListAdapter I don't see the out of
memory error.

Just wondering if anyone else has seen this and knows of a way to
solve it?

Thanks, Example of the Code is Below:


public class MyActivity extends ListActivity   {
   private MyAdapter myAdapter;
   private ArrayList data = new ArrayList();

  @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dictionary);
 this.myAdapter= new MyAdapter(this, R.layout.mylayout, data);
setListAdapter(this.myAdapter);//<--- If I remove this
line I do not see the memory leak on rotation of the screen
 }

@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
setContentView(R.layout.main);  // <-- Needed to load
portrait/landscape layout
}
}

Re: [android-developers] apps-for-android.googlecode.com/svn

[Mark Murphy]

Run:

android update project -p .

from the directory containing AndroidManifest.xml -- this will
generate default.properties for you. Most likely, it'll complain about
not having a target, which means you'll need to also add the -t switch
with an appropriate build target API level.

That is a poor rationale. Use onSaveInstanceState() and
onRetainNonConfigurationInstance() to hold onto your data model
between the old and new instances, please.

Agreed. I don't remember the Legend, but the Milestone would have
shipped with an earlier version of Android than 2.1, then got OTA
upgraded (or the equivalent). It may be that Motorola missed whatever
corner of the firmware has the value that gets returned here. For the
Milestone specifically, you might consider asking your question on the
MOTODEV support boards.

[android-developers] Re: java

I'd suggest you get a decent book on Java and play around with it a
bit before tackling Android.  Shouldn't take a lot with your
background, but a few days doing that would be time well spent.

(Trying to think of an application to implement, but nothing coming to
mind at present.  Maybe someone else has an idea for a command line
Java app/toy?)

[android-developers] Re: ListActivity Memory leak with onConfigurationChanged

[Taf]

Hi Mark,

Yes, I think I'll have to look at using the the way you've suggested.
It was just that
onConfigurationChanged seemed like a really nice and simple way of
achieving what I wanted. Though
it does say somewhere in the docs that it should be used as a last
resort. Not sure why? I guess it
circumnavigates all the Activity life cycle calls and hence you can
end up getting memory leaks as I am seeing.

Thanks for the quick response.

[android-developers] Re: replace transparent color bitmap with alpha

[Bob Kerns]

OK, color me confused. Why are you expecting to do this with PorterDuff?

PorterDuff works on images (or colors) with alpha to combine them. The alpha 
controls how they combine.

I don't see any way to get information from the color channels to the alpha 
channel via PorterDuff. The output alpha channel is always a function of the 
source and destination alpha channels -- and not of the color channels.

Even if there were modes that derived alpha from color -- what you're 
looking to do is very different than the sort of operations involved in 
PorterDuff. Except for clamping the result between full-on and full-off 
(however you choose to represent those values), PorterDuff operations are 
linear.

Have you considered painting using AvoidXfermode? I.e. construct your paint 
with an Xfermode of new AvoidXfermode(, 0, 
AvoidXfermode.Mode.TARGET).

Here's a twisted little app that demonstrates, It constructs two changing 
bitmaps -- a background gradient and a foreground. It alternates between two 
modes -- Opaque and Transparent. In Transparent mode, the Color.MAGENTA 
circles are replaced using AvoidXfermode with transparent regions, showing 
the background. It also replaces a square region with half-transparency of 
the same color via the same general technique.

Please view responsibly.

It does not force you to reload all of your resources. Hence, you have
to do all that yourself.

You might think "well, gee, it's portrait <-> landscape, so I just
fiddle with my layout, how tough can that be?". But then, what happens
if the user changes their locale while your app is in memory? They
come back to your app, and either:

1. You added locale to your android:configChanges attribute, in which
case you have to have all of the code yourself to reload all of your
visible strings, and not miss any

2. You only have rotation-related values in android:configChanges, in
which case your app probably crashes or otherwise has results that you
don't like, because the old activity will be destroyed and a new
activity created

There are a fair number of configuration changes (see the docs for
android:configChanges). One way or another, you have to handle all of
them. Using android:configChanges, therefore, is best for places where
the pain of manual resource management (and getting right now and as
you change resources in the coming months) is still less than the pain
caused by destroying and recreating an activity.

Re: [android-developers] Re: Is there a min SDK level for "android.hardware.telephony" feature?

[Mark Carter]

I've experienced this with the following devices:

Motorola Milestone (7), Spice Mi-310 (8), HTC Desire (7), Samsung Galaxy
Apollo (7), T-Mobile myTouch 3G Slide (7), ZTE Racer (7), Nokia N90 (10),
Taiwan Mobile T2 (7), Samsung Galaxy 5 (7), HTC Legend (7)

I expect some more devices will pop up over the next few days.

Side note - Nokia N90!?

To summarise, I think there are too many devices to hardcode these special
cases. The sim card check may be enough though I'm still open to other
suggestions...

Actually, the main reason I'm checking for this is to know whether or not to
show a list of SMS messages. So maybe a better approach would be to do a
quick check for what the SMS content provider returns. Won't be good enough
to check for the presence of messages (i.e. no messages won't prove
anything) but maybe there is something else to check for in this regard to
discover whether SMS messages are applicable to the device?

[android-developers] Re: java

[Robert]

WIth those 3 languages you should be good.  I had trouble wrapping my
head around the Android Activity Lifecycle.  Suggest you read the
following and reference often:
http://developer.android.com/guide/topics/fundamentals.html
http://developer.android.com/guide/topics/fundamentals/activities.html
particularly 
http://developer.android.com/guide/topics/fundamentals/activities.html#Lifecycle

To understand the lifecycle I found it helpful to put in stubs for the
routines like  OnPause OnResume OnStart, OnDestroy and others with
nothing other than a Log.d message to show when they were called.
(including Log.d in OnCreate).  I was really surprised to see that
OnCreate is NOT called every time that the launch icon is touched and
that OnPause is called when going to the settings, OnResume when
coming back.   Orientation change is even more interesting.  It's one
thing to read it, but much more concrete when you see it in your own
program.  The Lifecycle does matter when writing code since the
program is a living entity that may be around for days on your phone
and never totally start from scratch.

I came to Android/Java from 30 years of Assembler, COBOL, FORTRAN,
PHP.  The concept of objects having methods (that look like what I
knew as subroutines in the code) and programs that don't end when
finished (COBOL Stop Run,  Java: finish() ) was a bit different.
After a couple of months using Google's App Inventor (http://
appinventor.googlelabs.com/about/) then I totally understood the
concept of objects and their related code.

 I've gone from thinking that Object Oriented programming is the next
level of "dumbing down " programmers to "that's  way cool and a good
successor to what we used to call "structured programming" ".

So in summary:
- Use App Inventor for a couple of apps
- read the suggested documentation
- do the tutorials as another person as suggested
- find a tutorial that does something you want in your program and use
it as the basis

[android-developers] Re: Display list of saved tables to be opened

[Robert]

Well I would put the names into a table that you can read (and maybe
some descriptive info too)  but you didn't look far to find your
answer.

A quick google for  "sqlite select tables" found:
http://www.sqlite.org/sqlite.htmlin there is a section "Querying
the database schema"   go read that and you'll find a SELECT that does
exactly what you want (actually more than you probably need).

Re: [android-developers] Re: java

What we do with students is implementing a common command-line database (of

basic Java stuff, not bad for a beginner. And I'm pretty sure there are a
lot of other options (possibly more interesting), although these are easy to
comprehend as what is the input, output, expected behaviour etc and one can
focus on the Java itself while coding it.

[android-developers] Ignoring magnetic field sensor, calibrating the accelerometer

[Socrates]

I'm trying to use the accelerometer sensor for a game.

1) I am currently ignoring the magnetometer and using a static value
for the magnetic field vector. My reasoning is that the magnetometer
is subject to interference and will likely give more varied values
than the accelerometer, so I'd like to not use it if possible. I'm
also not sure that it is necessary for most motion-based game
control.  Does this make sense?

2) I'm attempting to get a baseline accelerometer value, but it
appears as if the sensor returns a junk/default value for a given axis
unless a change is detected along that axis. So it seems as if I can't
get an accurate baseline value while the phone is lying perfectly
still -- am I understanding this right? Is there any way to work
around this problem?

Thanks.

Re: [android-developers] How to disable key press events!!

Hi Marcin,

For the In-flight entertainment kind of device. When ever there is

key ( mounted on the device + external key pad ) must get disabled for that
much time.

Any effective solution?

An "in-flight entertainment kind of device" is custom hardware running
custom firmware and therefore will solve this problem via that custom
firmware. Android SDK applications should not be involved in the
process at all.

Sure you can. Most file manager apps have a Samba plugin,
so you can mount windows shares. If you have a rooted
phone, you can do it the other way around too -- install
the 'Samba filesharing on Android' app and you can turn
your phone into a Samba server.

[android-developers] Re: Ignoring magnetic field sensor, calibrating the accelerometer

[Igor Prilepov]

1. Yes, there are a lot of issues related to the magnetic sensor but people 
still use it for thousands years so the real question is do you need it or 
not.
2. I don't know what does it mean "baseline values". Accelerometer always 
returns noise values (as well as any other sensor) - this is a nature of any 
real data source.
There is no "work around this problem" but there are many methods to filter 
noise out. All of them requires certain level of knowledge in math, 
statistics, etc. and they are very complicated. Take a look at Kalman filter 
on Wikipedia to get some feeling about this area.

[android-developers] Re: Timezone Question

[String]

No offense, Bob (and I do mean that, I value your posts on this forum), but 
I think we can safely assume that the OP knows how to calculate times of 
sunrise and sunset. He's already showing that in his app, from the sound of 
things, and is probably doing OK with that aspect.

The issue at hand is how (and maybe whether) to work around a user having 
set their phone to a different zone than the one they're actually in. Nobody 
says this is affecting the absolute (UTC) time of sunrise/sunset in the 
calculations, it's purely about display.

[android-developers] Problem setting file permissions when filename has a space

[Paul]

I have a question over at StackOverflow that's been sitting there for
over a month, and wondered if maybe someone here (or a Googlite) could
answer it.

http://stackoverflow.com/questions/5149739/android-problem-setting-file-permissions-when-filename-has-a-space

I have an app where I store .png images in the app's cache directory,
and as I am sharing these files via messaging, etc, I need to make the
files readable temporarily by everyone (i.e. chmod 755).

As suggested in another thread, I am running Runtime.getRuntime.exec()
to do this:

Runtime.getRuntime().exec("setperm chmod 755 /path/to/filename.png");

This works fine, and as I am filtering / and \, any name works...
except a name with a space, unsurpisingly. This fails:

Runtime.getRuntime().exec("setperm chmod 755 /path/to/file name.png");

So, coming from linux, I try wrapping the file path in quotes, which
works on linux, but still fails to change the file perms on Android:

Runtime.getRuntime().exec("setperm chmod 755 \"/path/to/file name.png
\"");
or
Runtime.getRuntime().exec("setperm chmod 755 '/path/to/file
name.png'");

Any ideas?

Thanks,

Paul

[android-developers] Wifi manually turned off, freezes phone, requires battery removal

[Cris94107]

Users are reporting a unique bug in my Remote Control App that when
they manually turn off wifi, their phone locks up, and requires
battery removal.

While I will work to fix this bug within my own App (Songbird
Remote),  I would think this is a bug in the Android OS, and there
should be no way a java App even if it wanted to, should be able to
freeze a phone, and lock it up requiring battery removal.

Any body else encounter similar issue when wifi is turned off
manually?

dtDate.setUTCMonth(dtDate.getUTCMonth() + 1);

 

//To ignore daylight saving time look for the lowest offset.

Re: [android-developers] Problem setting file permissions when filename has a space

[Dianne Hackborn]

No shell commands are part of the SDK.  Using shell commands is likely to
result in your app breaking randomly across devices and platform versions.

The recommended way to do this is to write a content provider, which the
other app can call ContentResolver.openFileDescriptor() etc.  It is actually
really easy to write such a content provider -- it doesn't need a database
or anything, just to implement ContentProvider.openFile().

Every situation I have seen where MODE_WORLD_* is used it causes more
troubles than just writing a content provider.  I regret having made that.

Re: [android-developers] Wifi manually turned off, freezes phone, requires battery removal

[Kostya Vasilyev]

Cris,

FWIW -

I've never seen this particular problem, but have seen WiFi get into a 
state where it's technically enabled, and yet does not function at all 
(i.e. no scans, no connectivity).

While I will work to fix this bug within my own App (Songbird

should be no way a java App even if it wanted to, should be able to
freeze a phone, and lock it up requiring battery removal.

Any body else encounter similar issue when wifi is turned off
manually?

[android-developers] progressbar spin counterclockwise?

[B Lyon]

I was looking into a simple way to get the (small) ProgressBar to spin
counterclockwise, and it seems to come down to the class
AnimatedRotateDrawable, which looks to be hard-coded to spin clockwise
- it sets the angle increment to 360/framesCount, with no apparent
option to change the sign of the increment.  Most people probably have
come to expect that, I guess.

A lot about this (public) class AnimatedRotateDrawable seems to be
kind of hands-off - two of the attributes are private somehow
(framesCount and frameDuration), and I couldn't subclass it in a quick
attempt to see about trying to tweak this behavior (not that
subclassing would have worked).

In my case, if I am showing the spinning progress bar at all (which I
don't need to - I think that it's just a nice touch), then I need to
be able to flip the direction.  Before I get off of this little
distraction for the moment, I was wondering if any one else had played
with this before.  I guess I could just assimilate the class, add
assumed-to-be trivial changes for the flip option, and then change the
indeterminate drawable on the progressbar in the code, but I was
wondering if I'm missing some obviously simpler way.

thx

RE: [android-developers] Re: Timezone Question

[Tommy]

Forgot to mention. I'm not sure if you are already using this but the Navy
has a nice pearl script you can POST to and retrieve a good bit of Sun/Moon
data. They have to forms one allows you to enter the city name and state to
get the data (not all cities are listed) the other allows you to specify
lat/lon and a few other fields to get that sun/moon data for anyplace in the
world.

 

The forms are below:

 

For City Name/State only:

-day-us

 

For the more advanced form:

Let me know if you have any issues using these forms. I'll be more than

No offense, Bob (and I do mean that, I value your posts on this forum), but
I think we can safely assume that the OP knows how to calculate times of
sunrise and sunset. He's already showing that in his app, from the sound of
things, and is probably doing OK with that aspect.

 

The issue at hand is how (and maybe whether) to work around a user having
set their phone to a different zone than the one they're actually in. Nobody
says this is affecting the absolute (UTC) time of sunrise/sunset in the
calculations, it's purely about display.

[android-developers] 'E-Mail Developer' button creating a lot of spam?

[Matt M]

Hello,

I added an E-Mail Developer button to my application and ever since I
get random e-mails throughout the day that either have an empty
message body or just one or two words in a different language (looks
like Russian or something similar, sometimes an Asian language).
Occasionally I get one that just reads "Good". At first I thought it
was just a user complimenting me, but its happened to much to be a
coincidence. For what its worth, just last night I updated to version
X and already the e-mails I receive are from that version, barely 24
hours old.

I'm worried this means my app has been hacked and decompiled.. but
thinking about it more logically I'm not getting just extra general
spam as if my e-mail had been 'stolen' and spread around, it's all
originating from the E-mail Developer button. Plus, my app is barely
equivalent in status to Angry Birds so I cant imagine it being at the
top of a hackers To Do list.

Is anyone else having this problem? If not, and you have an contact
button installed, how did you set it up? Maybe I went about it the
wrong way..

Thank you for your help!

Matt.

[android-developers] Re: Ignoring magnetic field sensor, calibrating the accelerometer

[Socrates]

Here's what I mean by a baseline value: I'm using
SensorManager.getOrientation() to determine the device's orientation.
I am only concerned with the difference in orientation relative to a
static orientation (which I'm referring to as the baseline value) at
any given time. The baseline value could be hard-coded, but I'd like
to have more flexibility and set this value based on the orientation
of the device when the application is started.

The problem I'm facing isn't noise per se; the initial values I get
from the sensor are consistently inaccurate, so I'm not sure how to
obtain a baseline orientation.

Yeah, I see it happen with my applications as well.

One user was nice enough to send me emails asking who the hell I was.
Several of them, actually (guess my email address was somehow added to their
contact list).

In recent versions of my apps I removed my email from one place and changed
it from a button into a link in another.

Those who really intend to get in touch with me can always find my site /
email in the about window or the Market details window, and they do.

I was able to get it to work with the following code:

final Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
final int transparentColor = Color.parseColor("#" + imageTrans);
Xfermode mode = new AvoidXfermode(transparentColor, 0, Mode.TARGET);
paint.setXfermode(mode);
paint.setColor(Color.TRANSPARENT);

final Bitmap temp = imageBitmap.copy(Bitmap.Config.ARGB_, true);
final Canvas canvas = new Canvas(temp);
canvas.drawBitmap(imageBitmap, 0.0f, 0.0f, paint);
tilesetBuilder.imageBitmap(temp);
imageBitmap.recycle();
imageBitmap = null;

Re: [android-developers] progressbar spin counterclockwise?

[Mark Murphy]

You could not use a ProgressBar, but rather your own Drawable resource
(e.g., a PNG file) and a RotateAnimation.

Or, you could use a pair of AnimationDrawables, each referring to the
same set of underlying PNG files, just in the opposite sequence.

Re: [android-developers] progressbar spin counterclockwise?

[Dianne Hackborn]

This is basically a special class for that progress spinner design.  Which
is now old.  In HC the spinner looks different.  If you try to hack on
whatever spinner you happen to get from the platform you are running on to
do something different, you will probably fail in one way or another as you
encounter a different platform with a different spinner.

I can't imagine why you need to have it rotate in the other direction, but
if you need something different you should just make your own spinner style
that has nothing to do with whatever is in the platform.

[android-developers] Re: ListActivity Memory leak with onConfigurationChanged

[Taf]

OK, that's a fair point. I've changed my code to use
onRetainNonConfigurationInstance now, and this seems to work nicely.

Thanks.

[android-developers] Re: how to center aligned multiline text

:-(. I dont think it will be good workaround. I need to make my
application compatible to different form factor and in case of tablet
it is coming in one line. So I can't put new line character.

Re: [android-developers] 'E-Mail Developer' button creating a lot of spam?

[Marcin Orlowski]

I have contact form built-in (so you type there and the it launches MUA for
sending). Former versions had no message length check. This resulted in
flood of empty mails as these "users" (to not offend them more :) most
likely found sending empty mail accurate entertainment. In later revisions I
check message length, and if it's shorter than (iirc) 25 chars you cannot
proceed and send it. Typing *that* much (even random) chars fortunately
appears too much for these people.

Re: [android-developers] progressbar spin counterclockwise?

[B Lyon]

thanks for the tips, Mark.  I'll play with it.  It might need to be an
animation list or whatever

btw - RotateDrawable would be a two-line way to do it (custom little
icon seems to get animated fine) to replace the indeterminate
drawable, but RotateDrawable seems to insist on rotating clockwise,
too... it sets toDegrees to max (fromDegrees, toDegrees), so you can't
specify it go from 360 to 0.

Dianne - in looking at your note again, I can't tell if you were
suggesting that the best thing to do (for someone want to do this in
the first place) would be to replace the progress bar functionality
wholesale (yes overkill).  Of course I want to avoid depending on
internals or anything else in the API susceptible to change.

Re: [android-developers] progressbar spin counterclockwise?

[Dianne Hackborn]

I don't know off-hand if progress bar has an API to set the drawable.  If
so, just use that.  If not you'll need to roll your own.  It would probably
be easy to copy the code out of the framework.

ProgressBar lets you change the drawables (setProgressDrawable()).

Re: [android-developers] progressbar spin counterclockwise?

[B Lyon]

Diane

it does have a public "setIndeterminateDrawable" - I can set it with a
RotateDrawable and it works to spin whatever I want there... which is
cool and easy... it just apparently does it clockwise only... I just
need to replace it with something that can spin stuff backwards
and I need to learn the other stuff anyway.

[android-developers] Re: Codecs on Android

[Bob Kerns]

Um, the platform documentation?

http://developer.android.com/intl/de/guide/appendix/media-formats.html

Your specific device documentation, from the manufacturer, if you're 
interested in what additional formats are supported?

Really, you kind of lost me when you start talking about people sneering, 
etc. It really sounds like you already know we'll point you at the easily 
accessible, googleable documentation. It doesn't sound you tried to find the 
information and failed. Masochism?

I think you have a couple further questions in there after you've read the 
documentation, but I won't try to sort them out for you. I will note that 
"the tablet" is a nearly-meaningless phrase, as there are any number of 
tablet-format devices from various manufacturers running Android.

[android-developers] Phone for development

[Raghav Sood]

Hi,

I was thinking of buying a new phone for development and zeroed in on Samsung
Galaxy Pro 
B7510.
I wanted to know if this is a good choice and if any of you have used it how
is it? Also will it be better than my current Optimus P500?

Thanks in advance

[android-developers] Connect to emulator with Putty?

[David Williams]

All,

Is there a way to connect to the Android emulator (I am on Windows 7) 
with Putty?  I did a search and tried connecting to ports 5554 and  
on the localhost, but that didn't work.

[android-developers] WebView and geolocation questions

[Moose]

I have been attempting for a few days now to get a webview to work with a 
location based service. Every post I can find seems to say the same thing - 
create a webchromeclient and override onGeolocationShowPrompt(). 

I have gone as far as directly creating a copy of this and running it.
Code: https://gist.github.com/886546
Web page used to test: http://www.sourcerebels.com/geo/

The web page loads everything up until Geolocation supported, and then does 
nothing.
Can someone at least test that code and tell me if they are having the same 
problem?

[android-developers] path to sqlite3 database

[lloyd1949]

By default, the sqlite3 database is stored at /data/data//databases/

Is it possible to change the storage location to a path on the sd card
for example?


If Yes, would this be something like overriding something like the
sqliteopenhelper, setting some global parameter?

Any suggestion/example would be greatly appreciated. Thanks.

[android-developers] Re: path to sqlite3 database

[lbendlin]

You may have to change it anyhow, as any database you in the package is 
readonly.  You can place the database onto SD card  but be aware that the 
card may be removed by the user.

eventually you can use a simple buffer copying

private void copyDataBase() throws IOException {
// Open your local db as the input stream
InputStream myInput = myContext.getAssets().open(DB_NAME);
// Path to the just created empty db
String outFileName = DB_PATH + DB_NAME;
// Open the empty db as the output stream
OutputStream myOutput = new FileOutputStream(outFileName);
// transfer bytes from the inputfile to the outputfile
byte[] buffer = new byte[1024];
int length;
while ((length = myInput.read(buffer)) > 0) {
myOutput.write(buffer, 0, length);
}

// Close the streams
myOutput.flush();
myOutput.close();
myInput.close();
buffer = null;
}

[android-developers] Re: Display list of saved tables to be opened

[Bob Kerns]

It's a database design question, not an Android question. That's not evading 
answering you -- it's probably the most helpful thing I'll tell you! 
Understanding that your question really has nothing in it related to Android 
will help you find the information you need, beyond anything I can tell you.

It's also a fairly basic database schema design problem. You clearly don't 
know the basics of how to design the schema for a database -- so that's what 
you need to go learn. That's really important knowledge for any programmer 
these days, so it'll be well worth your time.

With that said, I'll try to get you started, to connect your problem to the 
concepts.

SQL (and SQLite) databases are *relational* databases. That means, each 
table defines a set of relationships, and you represent your data in terms 
of the relationships. Each table defines a particular type of relationship; 
each column in a table defines a particular role in the relationship; each 
row is a separate relationship of that type.

Generally, I would NOT save each "project" in a separate table in the 
database. Let's look at the concrete concepts you have. (These are sometimes 
called "entities" in database design).

1) Project.
2) A main 2D array. You don't say clearly what it contains, but I infer it 
may be a 2D array of strings, so I'll go with that.
3) A parallel 2D array "A". Again, it's a bit unclear, but it appears it may 
be also a 2D array of strings.
4) A parallel 2D array "B" -- likewise.

So let's define our tables. I'm going to assume that we want fully-general 
2D arrays here, of arbitrary size and content, and that we'll actually use 
the database to represent them. That will illustrate databases a bit better 
than the alternative of encoding your data into a big string, and decoding 
it after you retrieve it.

I'm NOT going to go into the details enough to give you a concrete schema -- 
partly to save my time, and partly because you need to go read up on that 
anyway.

The logical place to start here is the Project table. But I'm not going to 
do that, because I want to illustrate a thinking process and strategy you 
need to be able to go through, called "normalization". So if you are feeling 
that's where we should start, you're right, but be patient.

Let's instead start with your main 2D array. A 2D array is logically a 
relationship between two positive integer coordinates -- let's call them I 
and J -- and a value, which we'll call V since I don't know what your data 
means. Further, each of these bits of data is associated with a project, 
let's call that Project_Name

So we have the following Array_Main
Project_Name I J V
Work 0 0 Elephant
Work 0 1 Fish
Work 0 2 Cow
Work 1 0 Pig
Work 1 1 Sheep
Work 1 2 Horse
Play 0 0 Cat
Play 0 1 Dog
Play 1 0 Hamster
Play 1 1 Iguana

OK, you can see we've represented two projects here and their main arrays, 
of two different shapes. We can do things like:

SELECT I, J, V FROM Array_Main
WHERE Project_Name = 'Work'

to get all of the main data for the project named 'Work'.

We can also select just a part of it, for example:

SELECT I, J, V  FROM Array_Main
WHERE Project_Name = 'Work'
AND  I < 2 AND J < 2;

(Thus illustrating we can store and use more data than we need to actually 
load at any one time).

Now we can do the same for the other two arrays, in two additional tables, 
Array_A and  Array_B.

OK, now let's take a look at what we have -- we have a piece of duplicated 
information in every row, in three tables -- the Project_Name. Collapsing 
this sort of duplication is called "normalization".  It's a whole topic of 
its own, but here what we want to do is pretty simple: Replace this string 
with a project ID, and have a separate table that establishes the 
relationship between project ID and name.

This has a number of benefits, most of which I won't go into -- but one very 
obvious one is, you can now rename the project, without  touching every data 
row in the database! It's also more efficient, extensible, etc. etc.

So now we have a table Project:
Project_ID Project_Name
 1 Work
 2 Play

and Array_Main (and _A and _B):
Project_ID I J V
1  0 0 Elephant
1  0 1 Fish
1  0 2 Cow
1  1 0 Pig
1  1 1 Sheep
1  1 2 Horse
1  0 0 Cat
1  0 1 Dog
1  1 0 Hamster
1  1 1 Iguana

Now, we can select our main data thus:

SELECT I, J, V  FROM Array_MAIN
INNER JOIN Project ON Array_Main.Project_ID = Project.Project_ID
WHERE Project_Name = 'Work';.

We can even write:

SELECT Array_Main.I, Array_Main.J, Array_Main.V as MAIN, Array_A.V as A, 
Array_B.V as B FROM Project
INNER JOIN Array_Main ON  Project.Project_ID = Array_Main.Project_ID
INNER JOIN Array_A ON Project.Project_ID = Array_A.Project_ID AND 
Array_Main.I = Array_A.I AND Array_Main.J = Array_A.J
INNER JOIN Array_B ON Project.Project_ID = Array_B.Project_ID

[android-developers] Re: Display list of saved tables to be opened

[Bob Kerns]

Generally speaking, if you need to query the schema at runtime, you're 
probably not making good use of SQL -- unless you're making some sort of 
schema-agnostic general tool.

Creating a table per project is not generally a good approach. It really 
doesn't let the database be a database, and may be very inefficient for 
creating/deleting projects, doesn't give you the referential integrity that 
you'd get with a foreign key constraint, etc.

Still, knowing how to examine the schema is a very useful skill during 
development!

[android-developers] Re: Android shared preferences assignments not persisting between emulator sessions

[roschler]

@Kostya, no I don't use "Wipe Data".

I don't know what the exact underlying problem was at this point but I
managed to fix things by manually deleting the sharedpreferences file
from the emulator's shared_prefs folder while in the ADB shell, and
then recreating it as an empty file using "echo -n >app_global".  Note
"app_global" is just an arbitrary name I chose for the
sharedpreferences file.  I can't be certain, but it looks like the
emulator will not recreate the sharedpreferences file if you delete it
yourself manually, like I did when I was having trouble persisting
sharedpreferences writes between emulator sessions and tried that to
fix the problem.  Now everything works fine.

Either write an HTML5 offline-cached Web app, or use PhoneGap as your
container. I'm not sure what you're gaining by rolling your own
container.

If nothing else, you're not calling
webView.getSettings().setGeolocationEnabled(true);

[android-developers] Re: Ignoring magnetic field sensor, calibrating the accelerometer

[lbendlin]

the initial values are not "inaccurate", they are just not what you think 
they should be. Define "lying flat on the table" - are you sure the table is 
level? in both dimensions? Etc.

Instead of fighting the sensor you could include a calibration function in 
the app that accepts the user's statement "now it lies flat on the table" at 
face value and uses it as the baseline.

Re: [android-developers] Re: WebView and geolocation questions

[Moose]

Thanks for the suggestion, I will definitely be looking into phonegap - I 
have seen it mentioned a lot lately.

I added the call to enable geolocation - the link to the sample code I 
posted isn't actually my own stuff.

It still doesn't make any sense that this functionality doesn't work as is 
though. I would really appreciate any insight into the workings of 
Goelocation. Maybe by pulling apart the phonegap source I'll be able to 
figure something out.

I'm still interested in functioning examples.

Re: [android-developers] progressbar spin counterclockwise?

[B Lyon]

thx

Are you referring to the setScaleX/Y new in SDK 11, which seems to be
certainly the way to try there?

You don't know what it actually does.  If the original poster for some
reason actually needs some animation that rotates counter-clockwise there is
no guarantee doing this will actually cause that to happen.  For example the
indeterminate indicator in the standard Honeycomb UI is not clearly rotating
in one direction or the other.

Re: [android-developers] progressbar spin counterclockwise?

[lbendlin]

no need for that . Use a simple Canvas scaling during dispatchdraw. That is 
supported all the way down to API3

@Override
protected void dispatchDraw(Canvas canvas) {
canvas.save(Canvas.MATRIX_SAVE_FLAG);
canvas.scale(-1f,1f, getWidth() * 0.5f, getHeight() * 0.5f);
 super.dispatchDraw(canvas);
  canvas.restore();
}

[android-developers] Honeycomb / 3.0 / OpenGL ES / Broken / Again!?!

[MichaelEGR]

Greets,

I finally jumped the shark and got the G-Slate and all my 3D demos
from the simplest to the much more complex result in a blank screen. I
just got the G2x too and have the Nexus S, N1, G1, Droid, etc. and my
engine / platform works great on every OS 1.5+... Auriga3D flies (old
build too).

TyphonRT, my soon to be released platform many years in the making,
manages it's own GL context and doesn't use the API / SDK provided
GLSurfaceView. As things go I've been in a massive refactoring
operation and can't currently compile the 3D stuff for about a week
more (currently using old builds that run fine on all devices
including G2x). This is the exact same thing that happened with
Android 2.0 w/ horrible OpenGL driver support, unannounced changed
implementations of core OpenGL ES methods (was it the implementation
of eglChooseConfig if I recall correctly you guys changed without
telling anyone). So you guys either changed an implementation of a
fundamental GL method or for some reason my GL attribute system is not
requesting a proper context or falling back correctly even though it
works on every other OS and device combination I have including the
G2x, so it's not a Tegra 2 thing.

All I got to say is that did you guys even try to test 3D / GL support
using an example / test case that doesn't use the API / SDK supplied
GLSurfaceView. It's obvious things are way buggy or something is not
right when managing ones own context / surface. Remember exact same
code runs amazingly well on all OS versions with a wide range of
devices.

I'm trying to pour some ice water on the back of my neck, but how can
you guys let such slipshod work get released (I really do appreciate
the work of the Android team, but not the poor quality / rushed
aspect). I hope a 3.0.1 is coming darn soon just like 2.0.1 and you
guys fix the issues just like 2.0.1.. I was delayed 2.5 - 3 weeks
finding workarounds for the 2.0 release. Granted 2.0.1 fixed things
too (6 weeks later; 3 after my workarounds), but guess what my bread
winning client canceled my contract back then due to the unplanned 3
week delay and I had major hardship. This time I just finished a short
term contract (non GL and something that got _a lot_ of press
recently), so I'm not going to be out on the street because of this
f'up. Can I now assume there will be major GL issues every OS release
with serious GL fundamental API breakage on major point releases
(let's not bring up Froyo and the borked Java bindings, so I guess
it's not just major point releases)?

Granted again it'll be about a week until I finish up some of the last
major refactoring here and can compile the 3D demos I have for my
engine / platform again and I'll get to the bottom of it and find the
egl error or which method call is misbehaving. I hope it's something
really simple like a wrong attribute combination. My system right now
attempts to grab a context with the following params and backs off to
lower parameters if nothing matches:

"High Quality" (Droid + really all 2nd gen and up devices)
EGL_RED_SIZE, 5,
EGL_GREEN_SIZE, 6,
EGL_BLUE_SIZE, 5,
EGL_DEPTH_SIZE, 24,

"Medium Quality" (G1, Hero 1st gen, etc.)
EGL_RED_SIZE, 5,
EGL_GREEN_SIZE, 6,
EGL_BLUE_SIZE, 5,
EGL_DEPTH_SIZE, 16,

So you guys either changed the implementation to a GL method or when
requesting standard high quality settings the G-Slate freaks / GL
driver freaks out and it thinks it has a proper context, but things
are borked.  As I said everything is fine on the G2x / Tegra 2 and
every other device and OS version 1.5+, so this points mostly to an
unannounced underlying GL method implementation change. I'll find it
in a week once I can compile my 3D tests / demos again, but if someone
from Google cares to pipe up and point me to the release notes that
owns up to any underlying fundamental GL API implementation changes
that would be great. You guys didn't do proper release notes for 2.0
and the GL method implementation changes had to be yanked from yah on
this list, so I can only assume the worst and that this may be the
case again. Now the answer is _NOT_ to use the SDK / API provided
GLSurfaceView. Thanks, but no thanks... I'm glad you guys have built
in workarounds or whatever is making all of your platform 3D tests
pass without examining the larger and more fundamental GL API usage.
Raw OpenGL ES API and custom context management / usage should not
break like this!  I seriously want to provide you guys with a non-SDK
GLSurfaceView implementation of a super simple spinning cube and it'd
be nice if it was added to the test suite as clearly you guys are not
testing non SDK oriented GLSurfaceView apps otherwise this would be
caught _EASILY_.

I'd also be a bit more gracious too if this wasn't the _4TH_ major OS
release to have serious low level graphics API problems. Like I said
this time I didn't lose a client over it, I can't begin to tell you
how professionally unsatisfying it is to have a client blame oneself
for a delay when it is o

Re: [android-developers] Re: Timezone Question

[Bob Kerns]

While one hopes he does, it's not always a good assumption.  But that aspect
wasn't the intended focus of my remarks.

The point is -- the timezone SHOULD have absolutely ZERO impact on the
actual calculated times.

There are really only three ways to get an error here that I can see. (Chime
in if you can come up with more!)

* Using the wrong location.
* Doing the wrong calculation.
* Displaying with the wrong timezone (including DST errors, but that
shouldn't be possible as a program error that I can see).

A fourth possibility is a confused user; I'm not sure how to break down the
possibilities there -- though using a TZ with different DST characteristics
might be included.

But I think the first step in sorting out the problem is to identify which
problem you have, and that was why I was covering the territory. I hope the
OP understands that I don't know any details of his knowledge or app, and
can disregard any aspect of my message he's confident he's adequately
eliminated!

Re: [android-developers] progressbar spin counterclockwise?

that is pretty simple and seemed to work (I needed to put it in an
overridden onDraw in this case)

well, there *was* a reason I was curious to see about getting it to go
counterclockwise -

and I am curious to go look at the HoneyComb one now

Re: [android-developers] Honeycomb / 3.0 / OpenGL ES / Broken / Again!?!

[Dianne Hackborn]

I am not aware of any existing GL applications that completely break like
this.  I have run lots and lots of the top applications on Xoom without
trouble.  Applications also haven't generally broken on previous platform
releases, and I am pretty sure there are many applications on Market that
don't use GLSurfaceView.

To be honest, I don't have more time than to just scan through your long
rant; it looks like most of what you are trying to do is let off steam than
look for anything constructive, so I'll leave it at that.

[android-developers] Re: Honeycomb / 3.0 / OpenGL ES / Broken / Again!?!

[MichaelEGR]

Yes apologies and thanks for your quick reply. You provide great info
and are timely which is appreciated.. I'd be glad to buy a round for
the Android team... um how large is it again? Android graphics team?
um the really cool graphics folks? at I/O ;) I should not be allowed
to post on the Internets after a long work session and these days its
6/7 days a week marching to launch as it's on my dime.. Do take it for
semi-serious plus the lolz though; I know you guys work hard and
Android has come a long way and it's still just beginning. I think
it's spectres from Android's past that are nipping at my heels in this
case due to the  similarity. I'm just a little knackered that I think
I know exactly the area things are failing in (init as things go) and
I can't immediately fix or test it nor can I afford at the moment to
get a Xoom or 3rd Tegra 2 device; will try and track a non G-Slate
down though. It's just odd things work great on 1.5-2.3 OS across
numerous devices, but not G-Slate / 3.0. I will let you know what I
find out soon.

For one brief flash while rapidly trying to rotate the screen w/
Auriga3D / quake 3 class engine I saw a flash of textures that all
looked correct; I haven't been able to repeat that though and as
things go though the intro screen for now is just a flat quad texture,
so it should show up as it's not rocket science. The simple 3D cube
demo of course is not working too, so init problem is likely and as
mentioned when I get this massive refactor done (I'm about to unleash
a component oriented platform of 550+ components that form a cross-
platform Java middleware SDK w/ lots of goodies + base engine +
component entity system support) I'll be able to test thoroughly the
3D demos in 1-2 weeks. I've been refactoring for months thoroughly
moving away from strict OOP. It was much more work than I thought to
create a robust component oriented platform. As I mentioned it's more
spectres of Android's past haunting me and scaring me to death that
something like this will happen after I release and potentially charge
devs for a quality middleware platform.  Basic GL init should just
work across the majority of devices or failures detected and displayed
to the user.. Black screen.. Not digging that so much. I'll be putting
in extra effort to detect errors during init and display user
actionable errors + error reporting. I actually have that in there
now, so also perplexes me why nothing would pop up.

Can you perhaps mention a Java based game of significant complexity
that doesn't use the API/SDK GLSurfaceView.. I like to compare my
efforts against Deadly Chambers, but it is using the API GLSurfaceView
and works out of the box on tablets (G-Slate at least) with no / minor
changes; nicely too on Tegra 2 devices. It would be good to reference
other Java GL non API / GLSurfaceView oriented apps in times of
crisis.

Some general worries though.. I've not shipped yet, but soon and these
issues again give me the jitters as I'd like to think other devs /
users would understand, but not everyone is so forgiving especially
when it's pro / paid middleware (GPLv3 w/ commercial license for the
core).

My hands are tied for now if you don't know of any specific underlying
GL implementation method changes then I just have to get the demos
back up and step through the init process and potentially test on
another Honeycomb tablet.

I'd offer sending you the simple 3D cube demo or anyone else for a
head check and that would be much appreciated.

Regards...

Re: [android-developers] Re: WebView and geolocation questions

[Moose]

So I might have discovered my problem.

I borrowed a friends phone and tested my app on it. It works.
The device I had been testing it on was the motorola xoom (wifi only).

By logcat, it seems that on the phone (CM6), does make the call to 
onGeolocationPermissionsShowPrompt, while the tablet does not  (edit: and my 
old phone - also CM6 - does not make the call to 
onGeolocationPermissionsShowPrompt) .

Possibilities:
- no sim card?
  - if that is the case, can I force it to get location from wifi?
- difference in permissions required? (unlikely, because dream is running 
the same ROM - although the dream already has issues. It got thrown across 
the room and hasn't been quite the same since)

My company is planning on using the xoom with the data connection when we 
roll out, does someone own one that could test and make sure the sample 
works? I can export and sign the sample, or if you can make it from the 
source I specified at the start of the thread.
That being said - is there some explanation about why the app won't perform 
the call to onGeolocationPermissionsShowPrompt?

Re: [android-developers] Re: Honeycomb / 3.0 / OpenGL ES / Broken / Again!?!

[Romain Guy]

What exactly doesn't work in your application? We have tested many OpenGL
applications and games from Market, found and fixed bugs. We also sometimes
found issues that were in the apps themselves but nothing as dire as what
you are describing (although I couldn't really parse what your problem is
exactly.)

What fails? Do you see a crash? Are things not behaving as expecting? Do you
get EGL/GL errors? How exactly are you initializing your context? There are
no special "workarounds" or behaviors in GLSurfaceView btw.

[android-developers] How to install Sense UI into my HTC Magic

[Nicholas Key]

Hi Android Dev group members,

I've been searching high and low about installing Sense UI into my HTC
Magic (the one that is loaded with Google ION) but couldn't find any
relevant search results. This is the closest I could find:
http://developer.htc.com/google-io-device.html

There are several terms that I do not understand, namely - root,
flash, wipe. My question would be, is it even remotely possible to
install Sense UI into my HTC Magic (I got that Magic phone from Google
IO conference).

Nicholas

What you are asking for is custom firmware. It IS possible to have HTC
Sense on your device (I had HTC Magic 32B before and it was running
Sense). You should spend couple days making yourself familiar with
rooting, flashing, changing bootloader or/and SPL. Good place to start
is xda dev. forum. These guys rock. Firmware procedures will void your
warranty so be careful.
Honestly, this forum is a bad place to ask questions like that. Go to
xda and read-read-read.

Paul.

Re: [android-developers] Re: WebView and geolocation questions

[Moose]

Further testing: 
Phone that already worked (with sim card) works without sim card over wifi 
(or gps?). 
Other phone does not work with or without sim card.
XOOM - still doesn't work
Got friend to install apk - they say it works on their phone as well.

gps 'in use' icon never flashes on any of the devices

I am completely baffled by this.

Thank you Paul.

I initially thought that it's not possible at all to install custom
firmware into Google's HTC Magic.
I'll spend some time looking at xda forum.
