[android-developers] Re: Class ServiceManager missing in Android 2.1

[FrankG]

I.E. for android.os.SystemProperties;

This class is their, also in 2.1, but not part of the SDK.

If you make some kind of platform extension and use the android build
system
you access this classes.

Good luck  !

You may wish to follow the issue 2794 discussion at
http://code.google.com/p/android/issues/detail?id=2794 and consider

[android-developers] Re: Force Close on calling add/insert to ArrayAdapter

[Eric F]

Looks like according to the documentation
http://developer.android.com/reference/android/widget/ArrayAdapter.html
ArrayAdapter needs to reference a TextView where it looks like you are
giving it the ID of a spinner.

[android-developers] Re: Latency due to Garbage collection on onPrevFrame

[Zsolt Vasvari]

The only way to avoid garbagge collection is to pre-allocate all the
objects used by your app.  You may have to use pools of objects or
tricks like that to make sure you don't create objects while the
augmented reality portion is running.  This is no different from an
action game.  There are some open source games out there that do a
good job at this, for example, Replica Island.

[android-developers] prob in attaching txt file while email from internal package file storage

[adag]

Hello,

I am successful in creating file using openFileOutput(). and can read
the file using openFileInput().
I am able attach file from external storage sdcard while emailing the
same using getExternalStorageDirectory as
sendIntent.putExtra(Intent.EXTRA_STREAM,
Uri.parse("file://"+Environment.getExternalStorageDirectory()+"/
zibra.txt"));

But while trying to attach file from the openOutputFile stored area
using sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+
getFilesDir() + "/zibra.txt"));, resulting emptied file emailing.
My file is stored in "/data/data/com.example/files/zibra.txt".

Could you please point out what is going wrong in it?
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_EMAIL, recipients);
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "attachment test");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse
("file://"+ getFilesDir() + "/zibra.txt"));

//("file://"+Environment.getExternalStorageDirectory()+"/
zibra.txt"));
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, "Send mail..."));

i think you probably need to override verifyDrawable

I think the new activity is the same application which you are running. Try

Re: [android-developers] Can't grok Activity life cycle.

[Leigh McRae]

The common case is where an activity is put into the background and 
isn't killed for memory.  Forcing an Activity to save it's state when 
it's not required is a waste of resources on a resource scarce platform.

[android-developers] Intercepting WebKitView resource requests, serving from classpath

[hansamann]

Hi all,

I'd like to create dynamic HTML in my app that will also include
referecences to a few images. The images should not be resolved /
requested by the internet, but instead I would like to somehow
intercept these calls and then respond will classpath resources to
those requests. I think this is similar how phonegap or titanium do
this, but this is just an assumption.

Does anyone know how webkit's resource loading can be intercepted and
resources can be served from a local cache/ classpath intead of
contacting the internet?

Cheers
Sven

[android-developers] Picking up contacts: difference in behaviour between HTC and NexusOne - SDK 2.1-update1

[frantz lohier]

Hi,

I wrote an app that invokes the contact manager in the following way:

Intent pickcontact = new Intent(Intent.ACTION_PICK, People.CONTENT_URI);
startActivityForResult(pickcontact, CONTACTPICKED);

I am experiencing 2 different behavior between HTC phones and the NexusOne,
all with firmware 2.1-update1.

Thanks work properly on the NexusOne (i.e., my application is getting access
to all my contact along the primary phone number of that contact list). On
HTC phones however (incredible and the hero), the list of contact I get
represents some sort of index as opposed to the actual contact name/phone
number.

Am I missing anything ?

Thanks,

Re: [android-developers] WSDL Webservice

It's much better in most cases to just write an API you can use on the
client end. I remember when I was writing a SOAP client for Hitbox, I had
the darndest time trying to set up Axis and find the correct WSDL. After a
day or two, I stumbled upon the API of theirs which was 100 times easier to
use.

Re: [android-developers] Parsing heavy data

[Frank Weiss]

AFAIK SOAP is a bit heavyweight for a mobile device, but in many cases
people have to use that existing legacy technology. Many people are using
lighter weight technologies such as SAX, XPP, JSON to download and REST for
bidirectional data. Also, do you really have to download all 10,000 items to
make your mobile application work effectively?

Re: [android-developers] Can't grok Activity life cycle.

[Leigh McRae]

If you have a world simulation with lots of entities an what not it adds 
up.  I just did some tests and onSaveInstanceState() always gets called 
when my activity is put into the background.  This is an unnecessary 
burden to put on the app developer and will lead to many game developers 
to just killing their activity and forcing the user to pay for the 
reload.  The framework should have been written for the common case and 
not the extreme.  Who's idea was it anyway to encourage the user to 
leave a trail of open apps behind them!

setting aside a few megs on the SD Card and storing your state there, 
pulling it into main memory only when it's needed.

[android-developers] Re: StackOverflowError in UI redraw

[Zsolt Vasvari]

Also, I just fixed my Android 1.5 issue.  I simply made sure that I
did a .toString() on all my CharSequence objects before calling
setText().  That removes a bunch of calls from the stack as well as
plaing String objects are simpler to draw than a generic CharSequence
Of course, that assumes that all your items are simple non-styled
strings, which were in my case.

[android-developers] Lost with custom drawable animation

[Tomtom G]

Hi everyone,

I'm currently developing an application with custom drawables and i'm
kind of lost.
I do not use XML since all kind of the parameters have to be computed
on the fly.
I have a main custom view holding all the gui.
I made a class mcDrawable extending drawable implementing
Drawable.Callback.
In its draw method, i draw a couple of primitive (circles, and so on)
An instance of mcDrawable is displayed via the onDraw method of the
view.

When I trigger a motionEvent in the view, it calls a certain method in
an instance of mcDrawable which modifies the shapes. Since I call an
invalidate() after each event in the view, the drawable is updated
nicely during the motion. So far, all is good.

When I stop the motion (ACTION_UP), it triggers another method in the
instance of mcDrawable which send a message to an Handler in
mcDrawable which animate it by the mean of delayed messages. However,
the View is not aware of these changes and therefore, does not redraw
the drawable.
To achieve the proper behavior, i made the view static, with a
Handler, and send a message from mcDrawable Handler to the one of the
view. When the view receive it, it invalidates. However, I don't think
that its the proper way to achieve this !

So my question is the following: is there a proper way for mcDrawable
to ask the View to redraw it, by the mean of Drawable.Callbacks for
example ? I understand that it may use a selfInvalidate() in
mcDrawable, but I don't understand how to link it to the view. Could
someone help me ?

Thanks !

Re: [android-developers] Can't grok Activity life cycle.

[Frank Weiss]

I wonder what you mean by a fair amount of serialization. It would seem to
me a kilobyte or so would suffice for most mobile applications. If it's
much, much more than that, I think someone suggested using a caching
strategy instead. I would suppose that means setting aside a few megs on the
SD Card and storing your state there, pulling it into main memory only when
it's needed.

Re: [android-developers] Can't grok Activity life cycle.

[Leigh McRae]

Got your reply late for some reason. I would agree with 
onSaveInstanceState being called whenever you are put into a killable 
state as it's the only thing that makes sense.  As it turns out I am 
just about to do some tests with the logging you suggested.  If this is 
the case it's a poor design IMHO.  If you have a simulation that 
requires a fair amount of serialization to save it's state it's not 
going to work all that well.


The Android way seems to suggest that you make an Activity per full 
screen and use the stack.  So when I push an Activity for something like 
my game options, I am forced to serialize my state if 
onSaveInstanceState comes calling when the common case will be that the 
user comes right back.  If I wrote code at work with comments like it 
may or may not be called, they would likely tell me to enjoy my new job.

I am having a really hard time grokking the Activity life cycle
concept.  The main issue is with onStop() and onDestory() not being
guaranteed to be called before the process is killed.  I though I had
it figured out when I saw that the system calls onSaveInstanceState()
when it's shutting down the activity to claim some memory.  Thing is
that the docs says onSaveInstanceState() will be called before
onPause() but how does the system know at this point whether the
activity will be killed by the system or the user?

Here is a use case:

1) My activity starts up and is running.
2) At some point I want to show a web page so I use an Intent to start
an activity.
3) The web browser covers my app/activity so I would expect onPause()
to be called followed by onStop().

At this point it's my understanding that all bets are off and I can be
killed at any point without be called.

4) Since the system has enough memory onSaveInstance() doesn't get
called.
5) The user presses home and decides to open some app which requires a
lot of memory.
6) System wants more memory and decides to kill my app but I am
already stopped (onPause() has been called).  What happens here?

I am finding this a really serious problem since onPause() pretty much
needs to be treated as onDestory() as far as I can tell. If my app has
to be able to survive being killed without onStop() and onDestory()
being called, why bother having them?
 

From
http://developer.android.com/guide/topics/fundamentals.html#actlife

under the heading "Saving Activity State", we find

"Unlike onPause() and the other methods discussed earlier,
onSaveInstanceState() and onRestoreInstanceState() are not lifecycle
methods. They are not always called. For example, Android calls
onSaveInstanceState() before the activity becomes vulnerable to being
destroyed by the system, but does not bother calling it when the
instance is actually being destroyed by a user action (such as pressing
the BACK key). In that case, the user won't expect to return to the
activity, so there's no reason to save its state.

"Because onSaveInstanceState() is not always called, you should use it
only to record the transient state of the activity, not to store
persistent data. Use onPause() for that purpose instead."

So the way I understand it is that onSaveInstanceState() is called
whenever the *system* is putting the activity into a "killable" state,
thus allowing you to save the current state for it to be reloaded when
your activity is loaded again, but if the activity is being destroyed by
a user action, (where there is no expectation of an unchanged state) if
you want to save any state, you need to do it yourself in onPause().

So in your use case onSaveInstanceState() *will* be called, and the
state can be saved, so 4) is completely incorrect.

Feel free to correct me if I am wrong
Hope that helps

Dan

Re: [android-developers] Encrypt and decrypt .apk files

[Dianne Hackborn]

It depends on what you are modifying.  If you are just changing a bitmap,
you can just modify that file.  However, whatever change you make, you will
always need to re-sign the .apk (with jarsigner) with your own cert.  You
probably will need to strip out the jar manifest files before doing so, so
that the existing signing is not bad (mismatching the contents).

Re: [android-developers] Use DownloadProvider or not?

DownloadProvider is not an SDK API, so should not be used by anything that
goes on Market.  You could copy its code into your app if you wanted to.

You can't - they don't respond to inquiries of any sort. You're probably

Your best bet is to review the policy and determine for yourself what you

[android-developers] Re: StackOverflowError in UI redraw

[Zsolt Vasvari]

Are you using the tab widget by any chance?  Because adding activities
inside tabs will take up at least 5 layers in your UI hierarchy.  I am
struggling with the same issue which only crashes on 1.5, 1.6+ is
fine.

Developing an app widget, while not terribly hard, is not what I would
recommend as a starting project. Make an ordinary Android application
first, then convert it to an app widget later.

So, you can start with Hello, World:

and work your way up from there. Besides the developer.android.com site
and this list, you might consider searching or posting on StackOverflow,

[android-developers] Use DownloadProvider or not?

[ivan]

Hello,

I'm building an extensive Android app that will be pre-packaged on
many soon to be released devices.

I have seen from the post that in general one should not use the
DownloadProvider, except for the cases where the app is prepackaged on
the phone.  This is correct, right?

I need robust downloading functionality that will allow

- Specification of the download location
- Specification of the connection type for download (i.e. WiFi only).
- Restoration of downloading after connection interruption
- Status of current download progress
- pause/stop/resume for downloads
- progressive downloading of media files to specific locations

Should I avoid using the DownloadProvider for downloading media files?

Are there any other downloaders available for android that already
handle such downloading feats?

Thanks.

Don't think it should, but you never know. How long ago was this? Apparently
the Android Market is crapping on itself the last few days which could be
the cause of the decrease in usage you noticed.

Yes, I looked there many times, and often got lost browsing the projects list at

For what it's worth, one my apps got included in several Linux distribs a couple
of month right after the first release, without me asking for anything. It was a
much simpler project of course, but it looked like a flexible standalone app.
And even if getting open, Dalvik doesn't yet /look/ like that, although it 
could.

Then maybe that it's just a matter presenting things as standalone projects, not
just git projects. A matter of communication. Right now, it all looks, or better
said, feels, like a whole big project.

Okay, I'll look forward into it.

Anyway, that was just my $0.99 ideas ;)

Thanks and keep up the good work!

I consider the question important, because according to the
description of onDestroy() given at the link, it is always called. For
it says, "Called before the activity is destroyed. This is the final
call that the activity will receive."

This wording seems pretty general and unconditional to me. If you
override onDestroy() in the emulator and put a log message there, you
should see it get called.

monolithic? Have you looked at git.source.android.com ? There are over
150 projects which are exactly modules.
When Dianne refer to branches she talks about release branches. Work
for froyo, gingerbread and what comes after must be in different
branches.

Although, some other projects can have their own branch strategy:
branching for sdk.git is now split from the rest of the platform, and
we follow our own release schedule, this is likely to happen for other
projects that move to the open.

Dalvik is its own module already. As to why it's not in Debian/Ubuntu,
you can talk to these guys. It's up to them to include it, not us.

We *have* modularity, we *are* moving non-sensitive projects to the
open (as Dan said Dalvik is working toward moving to the open).

It's not like we don't want to do all this stuff. It's just that it's
a huge projects (or a huge number of projects if you prefer), and
there's some inertia in the way we've been doing things and it's going
to take us a while to improve, but it *is* happening.

[android-developers] Soft keyboard “del” key fai ls in EditText on Gallery widget

[droidful]

Hi,

I am developing an application in Eclipse build ID 20090920-1017 using
android SDK 2.2 and testing on a Google Nexus One. For the purposes of
the tests below I am using the IME "Android keyboard" on a non-rooted
phone.

I have an EditText widget which exhibits some very strange behavior. I
can type text, and then press the "del" key to delete that text; but
after I enter a 'space' character, the "del" key will no longer remove
characters before that space character.

An example speaks a thousand words, so consider the following two
incredibly simple applications...

Example 1: An EditText in a LinearLayout widget:

--
package com.example.linear.edit;

import android.app.Activity;
import android.os.Bundle;

import android.view.ViewGroup.LayoutParams;
import android.widget.EditText;
import android.widget.Gallery;
import android.widget.LinearLayout;

public class LinearEdit extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

LinearLayout layout = new
LinearLayout(getApplicationContext());
layout.setLayoutParams(new
Gallery.LayoutParams(Gallery.LayoutParams.MATCH_PARENT,
Gallery.LayoutParams.MATCH_PARENT));

EditText edit = new EditText(getApplicationContext());
layout.addView(edit, new
LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));

setContentView(layout);
}
}
--

Run the above application, enter text "edit example", then press the
"del" key several times until the entire sentence is deleted.
Everything Works fine.

Now consider example 2: An EditText in a Gallery widget:

--
package com.example.gallery.edit;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.Gallery;
import android.widget.LinearLayout;

public class GalleryEdit extends Activity
{
private final String[] galleryData = {"string1", "string2",
"string3"};

@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

Gallery gallery = new Gallery(getApplicationContext());

gallery.setAdapter(new ArrayAdapter(getApplicationContext(),
android.R.layout.simple_list_item_1, galleryData)
{
@Override
public View getView(int position, View convertView,
ViewGroup parent)
{
LinearLayout layout = new
LinearLayout(getApplicationContext());
layout.setLayoutParams(new
Gallery.LayoutParams(Gallery.LayoutParams.MATCH_PARENT,
Gallery.LayoutParams.MATCH_PARENT));

EditText edit = new
EditText(getApplicationContext());
layout.addView(edit, new
LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));

return layout;
}
});

setContentView(gallery);
}
}
--

Run the above application, enter text "edit example", then press the
"del" key several times. If you are getting the same problem as me
then you will find that you can't deleted past the 'space' character.
All is not well.

If anyone could shed some light on this issue I would be most
appreciative.

Regards

Yes - read the very detailed documentation on the Activity Lifecycle. You
need to handle saving and restoring your instance state. Look at
onSaveInstanceState and onRestoreInstanceState in particular.

Patrick's problem is not the configuration changing - it's his app being
destroyed and recreated DUE TO the configuration change. Dealing with this
by handling the configuration changes is not the correct solution, though it
may work for this case.

If you do it this way your app will only survive an orientation change - it
will not survive being killed for other reasons. For example, if the user
leaves your app to go to another and comes back to you some time later,
without changing orientation, your app will have been destroyed and
recreated and none of your data will be restored.

I would suggest you use onSave- and onRestore- InstanceState - that's what
they're there for. Don't waste time handling orientation change if your app
doesn't call for it to then only solve a part of your problem.

Okay, I'm not a free software fanatic, but I'm going to tell you right away
(something that you may already know): a big part of the free software community
is likely to consider these reasons as unacceptable.

I do understand these reasons though, but I also know the community, and it's
not without reason that one of the most widely used tool is named 
"Subversion"...

I think that your problem is that the whole of Android is too monolithic. You
are mentioning branches where you could think in terms of standalone modules.

If you were to make it more modular then you could get a boost in contributions.

For example, let's take Dalvik, it's a great VM. So why isn't that included in
Debian/Ubuntu for example, why can't I: aptitude install dalvik?

Whereas WebKit *is*. There even are python bindings. Do you get my point?

With modularity, you could maybe safely turn non-sensitive modules into
standalone projects, which could be used outside of Android. And that could
result in wider interest.

Re: [android-developers] Reference an android project library from another android project

I'm guessing you're using Eclipse and adding to your Android library
project a dependency on a Java project?

This is not supported as an Eclipse project. You'll have to create a
jar file, and add it to both your Android projects.

[android-developers] Re: Why is Android so buggy?

[blahblah...@gmail.com]

I think we all appreciate the work that Google has done in open-
sourcing Android. Like Olivier says, most of us don't have the time to
spend in fixing open source bugs.

Most of the bugs mentioned admittedly are easily worked around. The
only serious ones are the socket ioexception bugs, but these may just
be in the emulator.

It would just be nice if Google could employ a few more people to go
through the bug list and really look at the serious bugs to try and
get them under control. That sdk setup.exe bug is a good example:
apparently Xavier thought it was fixed, and yet it is been listed as
an open bug since January 2010 (issue 5944).

Oh, and while we're on the subject of wish-lists, the documentation
needs work in many places. Apple has a useful feature - on the bottom
of all of their documentation web pages there is a 'feedback' link
allowing you to report bugs and missing information in the
documentation. It would be useful if the Android docs had something
similar.

Yes, that should be doable. You can control volume streams from SDK

Development has increasingly moved to the open.  Unlike many open-source
projects, we have a lot of complications that make it very difficult to just
throw everything into the open: from the fact that in many countries you
can't file patents after any information about them is publicly available,
to needing to work with hardware manufacturers on major new features that
are important for them to control the PR around for their devices.

Development tools, Dalvik, and other things are now done in the open.  There
is increasing desire to have the framework done in the open, but this is
challenging because it will by necessity mean we need to be working in two
branches, to continue to keep sensitive work private until it can be
released.  Given that we also are often working on two more more active
internal branches (for the current release under test, the next release in
development, and often the next release after that), the development process
for having yet another active branch (with all the corresponding merge
issues and correctly deciding which branch X work should go in) is...  not
pleasant to contemplate.

Also, we have been accepting an increasing number of patches from the
community.  I have regularly been reviewing and accepting multiple patches
every week, as have other framework engineers.  This is slacking off a bit
as we wait for the froyo drop, but I am sure it will pick up again.  Most
patches don't need to be done on the very most recent head.

Re: [android-developers] Troubles with hierarchyviewer

[Romain Guy]

HierarchyViewer cannot be used with user builds, for security reasons.
You can use it with debug builds or the emulator.

[android-developers] Is there some way to monitor the browser events without modifying webkit code?

[shuai yuan]

hi, all,

I am trying to recorder some events when browsing the web, like
keyDown, keyUp, Touch, ScrollDown, ScrollUp, Scale change, rotation
etc.
I wonder is this possible without changing webkit code?

Thank you all.

[android-developers] Cursor.moveToNext() and head controlled loops

[drsoran]

Hi!

I've wondering about the behavior of the Cursor.moveToNext() method.
According to the docs:

"This method will return false if the cursor is already past the last
entry in the result set."

this method should give good support for head controlled loops like:

   final Cursor c = 

   for ( boolean ok = c.moveToFirst(); ok && !c.isAfterLast(); )
   {
  // Do something ...
  ok = c.moveToNext();
   }

But during the move from the last entry to the position after the last
entry it returns false. I think this conflicts with the docs and
prohibits loops like above.

[android-developers] Fastest Android Phone -- HTC EVO 4G?

[Eric]

Hello,

Is it correct to assume that the best/fastest Android phone (hardware-
wise) currently available now, and for the near-term future, is the
HTC EVO 4G?  If not, can anyone recommend the competing phone?

Second, can I buy this phone (or any other phone recommended here)
without a cellular plan?  I am a new Android developer and I just want
access to the fastest hardware out there to test my application.

Thank You,
Eric

[android-developers] Troubles with hierarchyviewer

[Thom]

Hi,

I can't figure out how to acces to the view hierarchy through
hierarchyviewer :

- my device (tests with NexusOne/Froyo and Galaxy/Cupcake) is
connected,
- I start hierarchyviewer, I select my device in the "device panel",
- And when I press start the terminal dispalys :

protocol = 2
version = 2

but nothing else appends.

"Stop Servers", "Refresh Windows", "Devices" and "Load View Hierarchy"
buttons remains unavailable.
Did i do smthg wrong ?

Thanx.

Tom.

[android-developers] Encrypt and decrypt .apk files

[AndyP]

Hi All,

I was wondering how to break apart .apk files in Windows to see all of
it's components, edit some of the components, and put the file back
together.

I have been able to open up the file to see the components using
WinZip but I am unsure of how to re-"make" the .apk file again using
WinZip. Is there a special option within winzip or can you just change
the extension from .zip to .apk? Not sure if this matters, but
the .apk files are being used within Eclipse in an emulator as of now.

Thank you!

Andy

[android-developers] Bug/Issue tracker a joke!

[Colin]

I find astounding, rude and arrogant the complete disregard with which
Google treats people attempting to access help on the tracker.

Thread after thread - even ones that are 18+ months old, with 400+
posts and nearly 1000 stars, have gone completely unanswered - look at
the Wifi/Proxy issue for instance, or the Gapless audio, or even the
3g-to-WiFi switching issues that has many hundreds of posts and only
towards the end is there even a luke-warm response from Google! But no
ownership or actual interest.

Most of the tickets are still, perversely, marked as New even after a
year of people begging, pleading, demanding solutions!! No owner
allocated.

I could understand if somehow the development resources available to
the world's fastest growing and probably most successful mobile OS
were limited - but given the fanfare, hype, etc from Google, that
seems unlikely. But the VERY LEAST someone could do is respond to
these poor bastards, and acknowledge their pain, even if it is just to
say "we are too busy" to address this right now.

But no, the response is, no response. Deafening silence. The rudeness
and arrogance is mindboggling!! Where the hell are your customer
service skills?

[android-developers] Couple questions regarding gestures and system uis

[Josh]

Hello,

I'm a super noob to Android and have a couple questions... If there
are any links to examples that people know of I would love it if they
were posted.  I've been doing some searching and not seeing a lot on
what I'm looking for.

1.  Can have a program running in the background that will listen for
gestures across any view that is currently showing whether or not the
app "has focus"?

2.  Can you replace a core ui view with your own.  i.e.  Create a
keypad application that replaces the default android keypad with one
you have created.

Thanks in advance.

[android-developers] MediaPlayer and ShouCAST / How to retrieve Meta Data

[sebsto]

Dear All,

Like many others, I am trying to read a Shoutcast stream on Android
2.2 (Froyo).
I found out that MediaPlayer handles the stream out of the box,
without specific coding.

However, I wonder how to retrieve the meta data (ie song title) from
the stream.

The OnInfoListener.onInfo is never called for me (http://
developer.android.com/reference/android/media/
MediaPlayer.OnInfoListener.html).  Even if it was, doc is silent about
retrieving these metadata - is this something planned for a later
revision ?

I know of course I can read the bits and bytes myself, parse the title
out of the music stream and give the music bytes to MediaPlayer.
(already did that for another platform)

But because I am lazy (a good quality for developers ?) and because
MediaPlayer seems so close to perform 100% of the job, I would like to
double check with this group if / what I am missing.

Thanks for your help

Seb

[android-developers] TabHost Loads Listview that loads a ListView?

[Bill]

I have a project where I am using a TabHost (4 tabs). On the 1st three
tabs I use a ViewFlipper to go between a ListView and a View with
content. On the last tab however, I need to load a ListView that will
have multiple different kids of views. For instance, the 1st row will
load another ListView when clicked. The second row will load a View
with content when clicked, etc.

So far, I have everything working except when I click the row in the
4th tab, I am not sure how to load the other ListView. Use a
ViewFlipper?

Any help would be great

Re: [android-developers] Can't grok Activity life cycle.

[Daniel M. Drummond]

Perhaps testing your application, and outputting some info to the logs
will help you resolve your misunderstanding, ie. put a line in
onSaveInstanceState() to write a line to the logs such as
"onSaveInstanceState() Called", and put a similar line in onPause(),
onStop(), onDestroy(), etc. and then force the emulator/phone to run out
of memory by running many apps together, and also exit on a user
interaction, and see what happens by looking at the order of the lines
in the log.

I always learn things a lot better by experimenting, than by reading
docs.

[android-developers] Latency due to Garbage collection on onPrevFrame

[Jay Ha]

Hi.

I'm writing an Augmented Reallity codes that should works in realtime,

But the VM's garbage collection hinders my program's performance.


I checked my program's execution time for each in OnPrevFrame(byte[],
Camera)

and it execution time increases from around 50ms  to 120ms at just
after each garbage collection.


I copied parts of logs below.
(local time is just before and after of signal processing, and global
time is time stamps for every onPreviewFrame() calling )

[android-developers] Expandable List View OnClickListener....

[dKnow]

Hi
I have a problems with a projekt I am working on. I am working on a
calender in Android and its the first time I do anything with it. so
here are my problems

1) I used the Expandable List View Example from the Api Demo and I
wanted to ad a onChildClick event to get to anotherscreen

2) I wanted to switch between screens if the phone is turned from
vertical to horizontal and back. I got that done by adding the layout-
land folder , but when I am using the Expandable listview example this
wont work anymoor becouse the codeline "
setContentView(R.layout.main); "  will not be exepted in my class . So
what i wanted to do is to read out the sensor directly and ad a
listener for it that will switch between the screens.

I hope that was understandeble:) and that anybody can help me.

From
http://developer.android.com/guide/topics/fundamentals.html#actlife 

under the heading "Saving Activity State", we find

"Unlike onPause() and the other methods discussed earlier,
onSaveInstanceState() and onRestoreInstanceState() are not lifecycle
methods. They are not always called. For example, Android calls
onSaveInstanceState() before the activity becomes vulnerable to being
destroyed by the system, but does not bother calling it when the
instance is actually being destroyed by a user action (such as pressing
the BACK key). In that case, the user won't expect to return to the
activity, so there's no reason to save its state.

"Because onSaveInstanceState() is not always called, you should use it
only to record the transient state of the activity, not to store
persistent data. Use onPause() for that purpose instead."

So the way I understand it is that onSaveInstanceState() is called
whenever the *system* is putting the activity into a "killable" state,
thus allowing you to save the current state for it to be reloaded when
your activity is loaded again, but if the activity is being destroyed by
a user action, (where there is no expectation of an unchanged state) if
you want to save any state, you need to do it yourself in onPause().

So in your use case onSaveInstanceState() *will* be called, and the
state can be saved, so 4) is completely incorrect.

Feel free to correct me if I am wrong
Hope that helps

Dan

[android-developers] Reference an android project library from another android project

[darun]

Hi,
I have 2 android projects out of which I modified one to work as a
library. I want the main project to refer to this library to perform
few functions. While this scenario works just as expected, I want to
introduce one more functionality. I want to link this library project
with another just a java project which has code common to both Android
and Blackberry applications. This second part however doesn't seem to
work and throws "The application  () has
stopped unexpectedly. Please try again" with a ForceClose button.
I would greatly appreciate if someone can give a brief information on
how to make this work.
Thanks

[android-developers] How can I use the VideoView in the class that extends view?

[Emca]

Hello.

Actually I want to use the VideoView in the class that is extends
view.
But whenever I tried, the space is allocated but anything is appeared.
SO I've changed the background color, then I can see the how much the
view's area is allocated.
but inside is nothing in there.
and next trying is I overrided the onDraw().
and inside the onDraw() I insert the 'videoView.draw(canvas)' like
this.
but it also not work.
is there any way that I can use the videoview inside the class
extended view?

Thanks for reading.

emca.

[android-developers] Android Geolocation app, Find if a user is facing a certain Location using Digital Compass.

[Aidan C]

Hi Guys,

I'm constructing a geolocation based application and I'm trying to
figure out a way to make my application realise when a user is facing
the direction of the given location (a particular long / lat co-ord).
I've done some Googling and checked the SDK but can't really find
anything for such a thing. Does anyone know of a way?

EventY=164

Clearly it can be seen here that out of nowhere I suddenly have an
ACTION_UP for another note. Shouldn't I definitely get a ACTION_MOVE
first?

As shown in the end of the log, it's definitely not an error in region
detection, since the ACTION_UP event is clearly in the B4 region.


Every onTouchEvent() call is logged, so the log is accurate.

The relevant pseudo-code for the ACTION_MOVE logging is:

 Key oldKey = Key.get(event.getHistoricalX(), event.getHistoricalY());
 Key newKey = Key.get(event.getX(), event.getY());


Is this normal behaviour for Android (the jumping in coordinates)??
Can ACTION_UP events just arise without any previous ACTION_MOVE
towards it coordinates??

[android-developers] MP3 streaming seeking problem...

[Ravindra Kamble]

Hi,
I am developing one online streaming player where it should support
for the seeking also. Same time I am updating the values like Time
Played and Remaining Time.

If I am not moving the seek bar, I am getting the correct values by
MediaPlayer.getDuration(); and MediaPlayer.getCurrentPosition().

But when I am changing the seek bar position, the values returned by
the MediaPlayer.getCurrentPosition(). is greater than the
MediaPlayer.getDuration()..

After changing the seek bar position, I am calling the
MediaPlayer.seekTo() method.


Does anyone have any idea on this, what's going wrong
