[android-developers] Re: Removing unused resources.

Sure, delete the resource and see if the project still compiles or
not.

and if you press "DONE" and then start the app from menu , the appln

Hi!
When the AVD emulator can emulate over 1024M memory!

[android-developers] Re: APK signing and certificate for production device

Pratik,
well signing your application is only for the purpose of security
while uploading it on android market!
once you have genrate ur "private keystore" , u have to signed ur
application with that "private keystore" to publish it on android
market
once publish that apk and later if u redesigned or made change in
your app source code and want replace the app in the market u have to
use the same "private keystore" without that same keystore u cannt
change or modify the application thats the only purpose of it! as far
as i know

[android-developers] Removing unused resources.

I am looking for an efficient way to find out if a resource (mostly a drawable) is used in java or in an XML file.The problem is, that on my current project the drawables are changed often and now I have some drawables, which might never be used.Is there a tool/way to find those unused drawables without search each filename in the whole project?

Best Regards.

[android-developers] Help! Application crash while scrolling in listview

Hello,

I have a weird problem with listview, while using simplecursor
adapter. Here is the error

08-31 21:50:14.540: INFO/dalvikvm(12195): Uncaught exception thrown by

I have runQueryOnBackgroundThread implemented in my cursorAdapter,
which is invoked by the Filter.filter method call from the activity.
So I dont have any reference of the cursor in my activity. Everytime I
query I understand I get cursor changed callback in my cursor adapter,
which extends SimpleCursorAdapter

Here is how it looks

public void changeCursor(Cursor cursor) {
Log.d(TAG, "Cursor changed ... **************** "+ cursor);
if (cursor != null) {
setLoading(false);
}
super.changeCursor(cursor);
initSectionHeaders(cursor);
notifyDataSetChanged();
}

runQueryOnBackgroundThread just returns a cursor from a query.

Am I missing something, should the cursor be closed or managed
anywhere? Any help on the leads would greatly help. Thanks in advance.

[android-developers] Re: App Widget fails to be added, "thanks" to customized platform

Sorry for my English... What i mean is that, when i switch to
customized platform and are not using the private functions, the
program doesn't work (Even a "Hello" app widget program doesn't work).
The app widget with a configuration activity won't be added, while the
app widget without configuration activity works.

[android-developers] Re: onLocationChange never get called

Hi,

If the gps is blinking it is waiting for a first fix, go outside in
clear sky and wait for a few minutes for a fix. It also helps if the
device has a working internet connection to reduce time to first fix.

[android-developers] Re: AbsoluteLayout

Once you publish the app on the Android Market you will get complaints
from people who have devices with other screen resolutions. Then you
can go back to Eclipse and see exactly where the problems are since
those classes are crossed out.

To prevent these complaints read http://developer.android.com/guide/practices/screens_support.html

When using ListView you need to set the adapter on the view.

[android-developers] two icons for the same app

I have an application that I "install" via the Eclipse IDE toolbar
icon "run package.name.app". My phone shows two icons for this app.
(only one icon until recently) The icons look identical but the name
is long and I cannot see the end of either icon labels. Even if I
uninstall the app via Settings > Applications > Manage Applications,
the next time I run it from Eclipse, the two icons are both there
again. The app is only listed one time under Manage Applications. The
first time I noticed the second icon was after I included a second
activity that displays a WebView. Everything seems to work OK. I can
launch the second activity and close it just fine.

Why do I have two icons? (I did not include code because I do not know
which code might be relevant.)

Thanks, John Brown

Re: [android-developers] how many threads does android browser generate?

Thanks for your reply, Dianne. If I run the Android browser as my only application in Gingerbread on a quad-core smartphone, and the page to be loaded is stored locally in memory (no network delay etc, in this case, the browser is single-threaded only as no network connection?), I wouldn't see any performance scaling (or worse, as the OS may move the threads to another core less busy in a circle) from a single-core smartphone, everything else being the same?

Re: [android-developers] Handling Adjacent Fragments in ViewPager Contributing to Options Menu

Excellent. I'm looking forward to it. Thanks for your reply!

Re: [android-developers] how many threads does android browser generate?

Gingerbread isn't designed for multi-core CPUs. The browser doesn't try to create threads to use multiple CPUs, it creates threads to have multiple network connections.

Besides networking, browsers are pretty intrinsically single-threaded anyway. The complicated stuff all needs to run in one thread: DOM rendering, JavaScript, etc.

OK, so there are no specific priorities on user-generated vs. posted
events.

I posted much simplified code. This is the same Smalltalk VM port that
I mentioned several times in the NDK group.

The VM has an interval timer (which is N in my example), and when it
expires inside the native code, the VM saves its state and returns to
the Java UI code. Or otherwise it may return if there is nothing to
process (no input events). If return happened by timer, the VM will be
reentered ASAP (that is, after T in my example). Otherwise it may not
be reentered until another user event is registered. That is, zero-or-
near-delays between entering native code do not happen 100% of the
time.

All I am concerned about is not to have the "non-responding" dialog
and buffer pending events within the application.

Your explanation is very helpful.

Thanks again.

[android-developers] javascript call from intent browser

Need a help on Android .Hope you can help us on this .

From our application we are opening the browser using intent.

Here is the code

Uri uri = Uri
.parse("http://
www.google.com");

Intent internetIntent
= new Intent(Intent.ACTION_VIEW, uri);

internetIntent.setComponent(new ComponentName(

"com.android.browser",

"com.android.browser.BrowserActivity"));

internetIntent.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);

startActivity(internetIntent);

We are setting the flag FLAG_ACTIVITY_BROUGHT_TO_FRONT in the Intent
so that next time if we open the browser from our application then it
should bring the same tab in front instead of creating another
instance as the application id is the same and it is working fine

Issue is we need to call the JavaScript function defined in the
webpage .How can we call the javascript function using the intent
browser
From webview you can do that but we are not able to use the webview as
it doesn't fully support the html 5

Thanks

You send a message from the service to the activity, and the activity
updates the TextView. Whether you do this via binding and the listener
