[android-developers] SDK VERSION?

[Abhilash baddam]

Hi Friends,

 For my Application I am using target version as API Level 8 and I
mentioned minSdkVersion in manifest as 7.

1)  If the user is having SDCard automatically I want to install my
app in SDCard other wise in internal memory. For that I mentioned
android:installLocation="preferExternal" in the manifest file, but if
the user is not having SDcard whether the app will automatically
install in internal memory or not.

2) Whether this app will also run in the mobiles which contains 2.1 Android OS.

Re: [android-developers] Android, SQLite, massive (5000%+) loss of performance on a certain query, on a certain device

[Zsolt Vasvari]

I have 2 users (out of thousands) reporting this problem.  I am at a loss 
as to why this is happening, also.  It doesn't have anything to the data as 
the user claims they few rows.  I even had them recreate their database (I 
have a backup facility that that backs up/restores from JSON) and the 
problem still occurs.

One guy took the phone back because he suspected a hardware issue.  The 
other person never followed up, so I don't know if he solved it or what.

I have never noticed this and I have many-many Relative layouts.

[android-developers] Re: getAuthToken not working is ICS

[he.cao]

I tried API level 13, and it does not work.
The problems occurs only when the GrantCredentialsPermissionActivity
launched, and with a custom account manager.
In order to reproduce the problem, the app and account manager
implement must signed with different certifications.
I found a similar post here : 
http://code.google.com/p/android/issues/detail?id=23421
where you can find an example.

[android-developers] Re: How to change shortcut icons dynamically on home screen in Android ?

[Abhishek Kumar Gupta]

Hi TreKing,

Thanks for the reply. I am able to change the shortcut icon of application 
only when I am moving the application from launcher screen to home screen( 
i.e. when I am creating the shortcut icon of application). But, my 
requirement is to change the icon of existing shortcut of application on 
home screen. If you give any suggestion that would be very helpful to me.

[android-developers] RelativeLayout layout_alignParentRight changes parent

[rdietrick]

I have a RelativeLayout that encapsulates several other views.  I have the 
layout_width of the parent (RelativeLayout) set to "wrap_content."  If I 
set the layout_alignParentRight attribute of one of the child views to 
"true," it expands the parent layout horizontally to fill the screen.  Is 
there a way around this?  I believe setting layout_alignParentBottom="true" 
does the same thing vertically, while left and top don't.

Thanks.

[android-developers] ListFragment alwasy shows the loading screen

[kronos]

Hello:

I have an example similar to the Shakespeare example with one
ListFragment showing a list of items.  The second ListFragment shows a
second list based on the item the user clicks in the first fragment.
The data is taken from the Internet, so proper background threads are
used to leave the GUI thread do its thing.
The first thread loads the data OK.  But when the app loads the first
time, and every time I select an item from the first list, the second
list always shows a loading icon like a indefinite ProgressBar
component.  If I scroll a little, the ProgressBar goes away, but it
comes back every time I select a new item.

How do I tell Android the ListFragment has finished working on the
data ?

The second list is filled in onActivityCreate().  The ListFragment is
replaced with a new one as is done in the Shakespeare axample.  A new
Thread is run in onActivityCreate() to load the list in the
background.  Once the list is loaded a Handler.post() is issue to
update the actual list.

Thanks.

[android-developers] Re: Android, SQLite, massive (5000%+) loss of performance on a certain query, on a certain device

[Gene]

When you see huge differences like this on joins it often means one of
the inner columns is not in an index _and_ there exists at least one
pair of tables being joined that won't fit in cache. So I'd bet the
difference between the two devices is SQLlite caching, which could be
either RAM available to SQL or in th flash controller.

Re: [android-developers] Re: Supporting Galaxy Note Issues Due To It Displaying Itself as a LARGE screen layout.

[Brian Conrad]

I just changed to the  qualifiers (or elements 
depending on which article you read) and filtering looks fine in the 
developer console.  But now my A500 is shown as incompatible.  For 10+" 
screens only I used:






Logically that should keep that version to 10" screens and 720p or 
higher.  But that is supported with the A500 so they must have their 
data wrong on the A500.

For my app, the Acer Iconia A500 doesn't even show up on the supported

I can tell you that I created an emulator with Android version 2.3.3,
told it to be 1280x800, and it picked up my very specific layout that
I stored in layout-large-port-xhdpi-1280x800.  Was that a fluke?  I
don't know.  But we haven't had any complaints from Note users,
whereas if the old layout was used, we would definitely receive some
complaints.

I think Samsung was aware of the problems with the way that the Note
works with some apps, because my company was directly contacted by a
representative from Samsung who helped us work out the layout issue
with our app on the Note.

[android-developers] Re: Does the file Manifest.java in Android source codes contain all the list of permissions?

[michael]

I know. what I meant is that *whether Android has the file that
contains the list of permissions by itself*, disregarding the App
side, only the Platform side.

Apk cannot change the permissions in the Android platform, though they
could define the other permissions by itself.

There should be a data file that contains such information, otherwise,
how could the platform verify the permission requests from apps?

Re: [android-developers] Re: Android, SQLite, massive (5000%+) loss of performance on a certain query, on a certain device

[Kostya Vasilyev]

Those two devices might be using different sqlite versions. I've found from
my work that version 3.7 can be significantly faster than 3.6 for some
queries.

There are performance analysis tools built into sqlite, one is the usual
"explain", the other is a low level virtual machine trace tool. You could
probably find a way to use them from your application, at least the first
one.

If you cannot find a way to use those tools from the app, consider
obtaining sqlite binaries for the PC having the same versions as found on
the devices, and doing the analysis there.

Finally, regarding getCount - it's one of those Cursor methods that
actually cause the query to be executed and the result loaded into memory.
This is expensive, unlike the SQL parsing that happens before. In other
words, since you can't avoid loading the actual data, it doesn't make much
sense to try and skip getCount, as you'll only be postponing the inevitable.

It has not been abandoned. It also has not been updated, in terms of

[android-developers] Re: Google Maps are very old on Android

[g...@deanblakely.com]

TreKing,
The com.google.android.maps.MapView has been abandoned??  I must
misunderstand.  What tool do android developers use when they want to
display Google Maps in Android applications?  Where are those docs or
tutorials.  I figured that going to the Android developers center
would be the right place to go to learn about developing on Android.
No?

Any apk can define permissions.  There are core parts of Android that are

apk, go look in its AndroidManifest.xml.

[android-developers] Re: Android, SQLite, massive (5000%+) loss of performance on a certain query, on a certain device

[Weston Weems]

SQL performance often relies on indexing and quantity of data. Generally 
fields you join on are going to need to be indexed (as they appear to be 
pk's). Without a where criteria, you're effectively going to end up with a 
table scan on english words, and compounded by the joins.

I dont know details about the devices specifically, but it is possible 
sqlite isnt optimized for the nexus.

If you arent indexing your tables, do so.

Re: [android-developers] Android, SQLite, massive (5000%+) loss of performance on a certain query, on a certain device

[Dianne Hackborn]

You can get the SQLite version to perform acceptably.  You just need to use
it correctly -- set up indices as appropriate as needed for joins and such.
 I am not a SQL (lite or otherwise) expect in any way so I can't help you
with the particulars, but at the very least make sure you are actually
setting indices on the columns that are involved in deciding what rows are
included in the query result.

Also all you are doing by putting your query in the main thread of your
process is causing your process to ANR when it takes a long time.  The
query all happens in native code down in SQLite, so you won't see anything
in your java traces (nor typically anything interesting in native traces
either since most likely, yes, you are executing the query in SQLite).

[android-developers] Android, SQLite, massive (5000%+) loss of performance on a certain query, on a certain device

[momo]

I'm rewriting a simple translation app with a SQLite db.  There is an 
extreme hit to performance between two queries, but only on certain devices.

One query lists the english words in a ListView, the other lists the 
secondary language in a list view.  The data is structured differently, and 
is from a remote server.

Both are single SQL statements, run via db.rawQuery.  Both use AsyncTask to 
keep heavy lifting in another thread.

On both devices, the "english" query returns almost instantly (less than 1 
second, every time): 

return db.rawQuery("select _id as id, english as label from english_words 
order by english collate nocase", null);

On one device, the "secondary_langauge" query returns almost instantly as 
well.  No problem there, ever.  This is a Samsung Galaxy SII.  On another 
device (Samsung Nexus S), this query takes around 30 seconds.  This query 
has some joins, as follows:

return db.rawQuery("select definitions._id as id, secondary_language as 
label from english_words join definition_bridge on 
english_words._id=definition_bridge.word_id join definitions on 
definitions._id=definition_bridge.definition_id order by 
secondary_language", null);

I ran it in the emulator once, and got the same result as the Nexus S (the 
30 second hang).  It took a little 1.5 hours to download and parse the 
returns from the server on the emulator (which takes a few seconds on 
either device), so I gave up on further debug with the emulator at that 
point.

This is the only difference between the two operations.  The listView is 
the same, the adapter is the same, the AsyncTask is the same.  The number 
of rows returned is different - there are about 2000 english words, and a 
little over 3000 words in the other language.  I don't think this explains 
the vast difference in performance.

I took the query out of the AsyncTask to see if I could get some more debug 
info, and did get an ANR:

  at android.database.sqlite.SQLiteQuery.native_fill_window(Native Method)
  at android.database.sqlite.SQLiteQuery.fillWindow(SQLiteQuery.java:73)
  at android.database.sqlite.SQLiteCursor.fillWindow(SQLiteCursor.java:287)
  at android.database.sqlite.SQLiteCursor.getCount(SQLiteCursor.java:268)
  at com.whatever.adapters.WordListAdapter.getCount(WordListAdapter.java:39)

I rewrote the adapter's getCount method to return a cached count 
(determined during instantiation).  After, I didn't get an ANR again, but 
otherwise the performance was not improved and the query still took around 
30 seconds.

I'm totally at a loss.  As mentioned, everything but the queries is 
identical.  And on the Galaxy SII, there is no problem at all - less than a 
second to populate the ListView, even under abuse (touching the button that 
launches the request as fast as I could).

At this point, I'm wondering if it'd be better to abandon SQLite entirely, 
and using a Java model to manage data.  Assuming I can't get the SQLite 
version to perform reasonably, what could I expect in terms of performance 
using Collections (with the number of entries mentioned above), when I need 
to do a search for example (which I imaging would require iterating over 
the whole thing on each key event).

Any advice?

TYIA.

It is whatever you code yourself. You want SSL-based? Write it. You
want IPSec? Write it. You want L2TP/IPSec? Write it. You want PPTP?
Write it. In this respect, VpnService is to VPNs as Activity is to
user interfaces -- it is a necessary part of the framework that
provides some basic functionality, but the core of what you are trying
to do is what you write yourself.

> 2. What on earth do you do at the remote endpoint?

The other side of whatever you code yourself.

Nonsense. Just because you are handed a FragmentTransaction does not
mean you have to use it. You are welcome to do anything you want when
the user clicks an action bar tab.

[android-developers] Re: implementing fade-in/fade-out effects in Java with frame-based animation

[Serdel]

Yes the bitmaps are different, not only the angle changes (there is
also some kind of reflection effect on it and patterns). So rotating
the same image (which I guess is your suggestion) won't do the trick
here. I am also thinking about using the same fade in fade out effect
on another animation where a glowing bowl appears and hides in a a
kind of slow 'puls rythm' - here also the bitmaps are different and it
won't do with hiding in&out the same bitmap

Re: [android-developers] Same permission defined in multiple applications

[Dianne Hackborn]

I would recommend using it for .apks that are going to be built in to the
system image (not distributed on Market) and want to have their code
running in a common shared process in order to reduce their overall memory
footprint.  That is the reason this facility was implemented.  I think it
was a mistake to let it get out into the public SDK.

heinous that you would hijack an unrelated thread to ask it a third time. 
Do not be that rude, Sumit.

Go back and learn from the answers you already got. Stop being rude, please.

How does it not?  You have the documentation for the ProgressBar view, and
another link that gives you lots of tutorials about how to programmatically
get CPU usage info...  You shouldn't need any more than that.

Re: [android-developers] OnTouchListener with multiple views problem

[Bill Lahti]

I have worked with some code that was in the API 8 Android Launcher. I have 
found that it is a pretty good framework for drag-drop.
For more about the sample apps I built, see my answer on StackOverflow:

Re: [android-developers] Re: Email-dependent app

[Kristopher Micinski]

That's right.  The only way to extend functionality is to actually
write your own app, there's no way in existing apps to extend them...
(Unless they provide specific broadcasts, intents, etc... that you can
use, but this rarely happens, and it's almost never enough to actually
provide extra functionality for the app..)

[android-developers] Re: Casting string as a class (ie. RadioButton)

[Bozzified]

>
> Many thanks everyone.. Some good suggestions.

I mean I am getting how most things work in Android and have made great 
progress in making my own app that's fairly complex but I am still lacking 
experience in how to do some things because number of android classes are 
massive and it only comes with experience and usage.

You've given me some good pointers where to look to achieve what I need.

@Lee

I know exactly what you mean. I guess i have to straighten my mindset a bit 
in how Android treats and deals with view objects and how to target them as 
it is different from what I'm used to.

It's all coming into place though. 

I will definitely ask if I stumble up more. I am really happy this group is 
so active to help me learn better by suggestions.

Again thanks to everyone who replied.

Re: [android-developers] app freezes and get stucks

[James Black]

There are many areas to look.

Start with writing all exceptions to the log and perhaps before and after
loading images.

Then, when it locks up, get the log and see where it was when it died.

You may want to log going into onPause also.

Re: [android-developers] SMS as techinque for chatting

[Kristopher Micinski]

This isn't really a question that's formatted for this list.

This list is for discussing implementation issues relating to apps.

The answer is yes, you can, at least in some sense.  It depends what
you mean by "chat," you could mean it temporally, in terms of how you
display things, etc... This isn't clear from your question.

So basically, the answer is yes, you can do this, but if you have no
idea where to start, we're not really in a position to help you.

Agreed... What I would do is create a member variable for each
RadioButton.  Then show/hide and check/uncheck them as needed based on the
user events.  That is what I was trying to get at with my first response.

[android-developers] Re: Is there way of using NFC without Secure Element?

[Cadu Silvestre]

Jeff,

It really depends on what you wanna do.

Do you want to read/write some standard NFC tags? Great, you don't need a 
secure element.

Do you want to do anything related to Digital Certification or Electronic 
Payments? You probably need a secure element.

Animations don't have to be done on Android Shapes... They can be done on
any view, like an ImageView.  Is your set of bitmaps different in any way
other than the rotation?  If the only difference in the frames is the
rotation then you can use the approach I described.

[android-developers] Testing AndroidTestCase as well as ActivityInstrumentationTestCase2

[Weston Weems]

So I've built a test suite that automatically grabs all testcases and runs 
them.

The first chunk of tests I wrote were for AndroidTestCase, and just tested 
simple algorithms and shared functionality (non ui, Activity in-specific).

I came along and built a ActivityInstrumentationTestCase2, that happens to 
test the first activity of the app.

When run alone, all my AndroidTestCase tests run just fine, and likewise 
when running my ActivityInstrumentationTestCase, they run as expected. When 
I run all tests for the test project, it appears as if testrunner hangs 
trying to run my activityinstrumentaiton test cases. (APPEARS to be in the 
call to getActivity() in setUp()).

This as you might guess is terribly inconvenient. I was wondering if anyone 
has encountered it, and if so, any solutions out there?

I saw a post here about making sure to .finish() the activity in 
tearDown(), but as I only have one activity instrumentation test case, the 
.finish() didnt appear to have any effect on it whatsoever. Because 
getActivity() is called in setUp(), setting timeouts etc for the test 
themselves dont really seem to do much of anything.


Any advice would be greatly appreciated.

Re: [android-developers] Casting string as a class (ie. RadioButton)

[Nadeem Hasan]

All this is fine but OP needs to take a step back and ask himself why he 
needs to use a string as an identifier? In Android, numeric resource ids 
serve the same purpose and are already defined for you by the resource 
compiler.

No, this is a frequently asked question, but basically, you can't
"extend" apps you didn't write with arbitrary functionality like this.

Thanks for the response but the animation is a set of bitmaps that I

Not really. You're running on the assumption that the user would be using
the default email client. Such a thing may not exist, or be used, as the
user can install any Email client they want.

Regardless of that, being able to detect that a user is opening an email
client, and specifically viewing their Inbox, would be quite a specific
action to detect and considered to be a pretty serious security flaw, I
think. This should not be possible under normal circumstances.

This line says to me that all trains with service id 1, that run

You define a main.xml and don't use it, then you set a WebView solely as
the content view. I think you need to run the docs and samples - this is
Android 101 stuff here.

Re: [android-developers] OnTouchListener with multiple views problem

[metro]

hi
thanks for your answer.
I've tried this, but I found my problem (still isn't solved).
I have multiple imageviews over a framelayout (also tried with 
relativelayout)
their place over the screen is determined by Padding (dynamically) so the 
last Imageview added has the biggest "z-index"

The problem is, I can't choose the "smaller" z-index views because the last 
one is "over" them.

I believe this is not the drag&drop best practice.

Do you have some kind of example to give me?

Thanks !

Re: [android-developers] implementing fade-in/fade-out effects in Java with frame-based animation

[Justin Anderson]

Is there any particular reason you are using a frame-based animation?  I
haven't done any frame-based animations, but I know you could accomplish
the same (or very similar) thing using an AnimationSet defined in XML.

You could then specify a rotation to the image as well as a fade in/out
with alpha...

As a simple example, this could go in res/anim and be called something like
spin_fade_in.xml:


http://schemas.android.com/apk/res/android";>

Re: [android-developers] Casting string as a class (ie. RadioButton)

[Kostya Vasilyev]

Well, you can use this to go from identifier-as-a-string to
identifier-as-a-number:

http://developer.android.com/reference/android/content/res/Resources.html#getIdentifier(java.lang.String,
java.lang.String, java.lang.String)

Another option is to specify tags for your buttons with
android:tag="blahblahblah" in the XML, and then use
View.findViewWithTag:

http://developer.android.com/reference/android/view/View.html#findViewWithTag(java.lang.Object)

I understand that neither option is very fast, so use carefully (cache
the results in a more directly accessible data structure).

[android-developers] implementing fade-in/fade-out effects in Java with frame-based animation

[Serdel]

Hi,

I am running an animation of a spinning star and I would like to add
some fade-in/fade-out effects. I am loading the animation in Java by
making the AnimationDrawable objects, and adding the bitmaps as frames
and then setting it to an ImageView using setBackgroundDrawable. I
there a way I can add fade-in fade-out effects to this animation? I
couldn't find any help on that subjects so far.

Re: [android-developers] Casting string as a class (ie. RadioButton)

[Nadeem Hasan]

In your base Activity class, add this:

protected RadioButton findRadioButtonById( int id ) {
return (RadioButton) findViewById( id );
}

This could of course throw an exception if the id does not represent a 
RadioButton.

Re: [android-developers] disabling firewall

[Robert Greenwalt]

You're initiating the traffic on the device but not receiving responses?
 Or are you trying to run a server socket on the device but
off-device originating traffic can't seem to connect?

I don't think there is any firewall on the device, though I wouldn't be
surprised if carriers needed to do some NAT to conserve ipv4 addresses.
 Are you using mobile data or wifi?

Re: [android-developers] Casting string as a class (ie. RadioButton)

[Bozzified]

Oh, yeah I can do that. I can do manual check and target specifically radio 
buttons I need with switch.

What I"m trying to do is target specific instances of RadioButton class in 
this case based on my XML input I got from CMS and the choices users set in 
it. For example what radio buttons will show and which ones wont'.

I"m trying to make 1 simply method that will look like this:

private void turnRadiosOnOff(int radioButtonID){
   // and then I would target a specific radio button based on the ID 
passed into this method like this:
   RadioButton radioInstance = getRadioChild("_radio"+id);
}

So in my layout I would have all radio buttons defined but code would hide 
them all with GONE and then I would just reveal the ones they selected in 
the XML file by using this one simple method above by passing a simple ID.

Hope that make sense.

Re: [android-developers] Same permission defined in multiple applications

[Justin Anderson]

I have only ever used it in once case...

I have two apps on the market.  Once is free and the other is a paid plugin
that unlocks features in the free app.  The sharedUserId setting was
perfect for me because it allowed me to do my license checking in the paid
app and save certain things about license validation to SharedPreferences
and then my free app could read those and unlock certain features.  The
unlock "key" app really did nothing but license validation and, if launched
by the user, essentially just launched the main app.

In my case I didn't have to worry about the subtleties...

[android-developers] can't find my resources in my service...

[RedBullet]

So, I noticed something a little odd as I was refactoring my code. 
Basically I am moving a bunch of code from an activity to a service, and 
this included a Notification.

In my notification I reference a String and an Icon which are both in my 
resources (R.drawable.myicon for example).

When I moved this code to my Service class it was no longer able to resolve 
that path...

Stumped... But must be missing something fundamental.

[android-developers] bitmap.recycle()?

[bob]

I'm looking at some of the samples in apidemos, and I saw this:

Bitmap bitmap;

try {

bitmap = BitmapFactory.decodeStream(is);

} finally {

try {

 is.close();

} catch (IOException e) {

 // Ignore.

}

}

GLUtils.texImage2D(GL_TEXTURE_2D, 0, bitmap, 0);
bitmap.recycle();


Anyone know why they are calling bitmap.recycle()?  Is that really 
necessary?  Isn't the garbage collection automatic?

[android-developers] Re: Removing an item from ListView

[radhakrishna]

@seshu

You mean updating onListItemClick method in
TestListItemsView1Activity :
-
protected void onListItemClick(ListView l, View v, int position,
long id) {
super.onListItemClick(l, v, position, id);
Toast.makeText(this, "Click-" + String.valueOf(position),
Toast.LENGTH_SHORT).show();
 dataValues..remove(position);
}
-

This does not work for me, I need to click remove button to remove
listrow.

My ListView contains [TextView and delete Button], I need to delete
list row, when I click on Delete button, When I click On Delete button
it will not enter into onListItemClick method under
TestListItemsView1Activity class , it will enter only when I select
TextView (Text).

Onlick method for delete button located in EfficientAdapter class.

Re: [android-developers] AlarmManager.RTC don´t work

It's actually different: using RTC does not ensure that the device
will be woken up just to fire this alarm.

This is not the same as "using RTC ensures that the device will stay
asleep and not wake up for any reason" -- that's not the case.

Probably nothing.

Perhaps the device woke up for some other reason, and so your alarm was fired.

The token is cached and has a certain validity period. If you get it once
(while online), you should be able to use it even if offline if it is
still valid.
That said, what exactly the Google accounts manager does is undocumented,
so it might be trying to connect for some reason even if you have a cached
token. Or it could be a bug. Test different cases and check what the
exception traces say.
