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

[Dianne Hackborn]

Start with the app widget sample in API demos.  If this isn't working, your
"customized platform" is broken.

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

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

[C++ Narayanan]

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

I am looking for an efficient way to find out if a resource (mostly a

[android-developers] Re: Android installer strange issue

[rich friedel]

It is per design. You should call finish() on your activity in your 
onDestroy() method.

Again, I highly recommend you familiarize yourself with the Activity class 
and its lifecycle.

[android-developers] Re: Android installer strange issue

[Sudha]

But,
When you install and press "done" instead of "open"
and repeat this testing, the activity will resume form the place you
pressed menu button.
only when you press "open" and repeat it wont resume,it will restart.

So its not as per design I guess.else teh application should have
behaved the same way in both the scenarios.

[android-developers] Anyone notice app usage down since early July for High Maturity apps?

[pawpaw17]

Hi Guys,

I have an app that has been in the Market since June 2009. I had been
seeing a steady build of users and pageviews for many months, but in
July the trend reversed and I'm down almost 20% both for visitors and
pageviews since then. Some of my users told me the app seemed the
"disappear" from the market - I think google twiddled with the default
maturity filter for some versions of the market, and users - without
knowing it - all of a sudden were filtering for "Everyone" rather than
'All Apps". This might have been fixed now, but I'm not sure.

Anyway, my app might be just sucking wind right now, but I wonder if
any of you have noticed a similar trend since early July.

Thanks!

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

[photon]

Hello,

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

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.

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.

If the gps is blinking it is waiting for a first fix, go outside in

[android-developers] Re: AbsoluteLayout

[nadam]

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

[android-developers] Re: two icons for the same app

[Streets Of Boston]

Look at your AndroidManifest.xml file.
If you have *two * items whose intent filters look like this:





then that's one too many (if you don't want two of them).

If you have only one activity with that intent-filter, then i'm not sure 
what is causing your problem.

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

[Dianne Hackborn]

I really don't know what you are trying to get at.  As I said, as far as I
know browser CPU use is generally pretty single-threaded -- the DOM
rendering and JavaScript interpreter all need to run in the same thread.
 Just creating more threads doesn't magically allow this work to be spread
across them.

And again, Gingerbread was not written for multi-core CPUs.  In fact if you
try to run stock GB on a multi-core CPU you will be extremely unstable
because there are many things not working correctly for SMP, especially ARM
SMP.  So it doesn't make sense to ask questions about how stock GB runs on
multi-core, because it just doesn't.

If you are wondering about a particular phone someone has released with GB,
you will need to talk with that manufacturer, because they will have needed
to do some work to have GB run on a multi-core CPU.

[android-developers] two icons for the same app

[john brown]

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?

[Jack Harvard]

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?

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

Right, the system calls it for you when it needs to. I mean confirm that
this is happening. A break point or log message would do it.

It was what I understood about the samples. But I do not know how the
GridView does that and why it is not happening in my app.

You don't call it. GridView does.

You might consider starting with a ListView. GridView is not
significantly different from ListView in terms of how it interacts
with adapters, and there are many more samples demonstrating ListView.
Once you have a custom Adapter working with a ListView,
convert it to a GridView.

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

[Dianne Hackborn]

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.

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

[Jack Harvard]

I want to understand how many threads Gingerbread generates in order to 
understand how the browser performance scale with multicores? For example, if  
"a few " means 2, that means 4 cores wouldn't scale the browser performance by 
anywhere close to 4 times. I understand that Gingerbread doesn't officially 
support SMP, sometimes browser does crash on multicore platforms, it's not a 
problem for me though.

Is your getView() even called?
Have you confirmed it's actually on the screen and sized to be visible? (Put
some funky colors on it or something)
Have you tried simplifying your getView() to just return a TextView with
some hard coded values, to make sure that part works?

P.S. - there's no reason to be setting the convertView if it's null

Re: [android-developers] Re: How to 'delete' allocated class by 'new'??

[Streets Of Boston]

As other have stated, Java Objects are garbage collected:

If an Object cannot be reached (from any of the current threads' 
stack-frames or from the heap), directly or indirectly, i.e. there is no 
path to the Object, then this Object can be garbage collected. 
It is impossible to 'delete' an Object in Java.

You can help (just 'help', not force) the garbage collector along a little, 
by setting references to null ("b = null;" in the above examples). However, 
this hardly helps the garbage collector at all. It's not of much use.

You can call System.gc() to indicate that the garbage collector should run 
a.s.a.p. Again, this may or may not work, since calling 'gc()' is only a 
hint. The actual behavior may vary.

If you're dealing with bitmaps, calling bitmap.recycle() may work for you to 
free up memory. Be careful doing this. Make sure other parts of your code 
don't still have a reference to this and use the now recycled bitmap,.

My answer is another question to you:
*Why do you want to know this?*

My problem is to populate the gridview. I already saw through the debugger
that my code is reading the data correctly from the table, but when the
activity is started, the gridview do not display nothing.

My getView() method is:

public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub

TextView label = (TextView)convertView;
if (convertView == null) {
convertView = new TextView(this.context);
label = (TextView) convertView;
}
label.setText((getDataFromTable().get(position)).toString()); //the
geDataFromTable() returns a list with the data from the table (tested
observing the debugger)

return(convertView);
}

In my activity I have:

...
ColetaDatabaseAdapter adapter = new ColetaDatabaseAdapter(this,
R.layout.data_display);

GridView g = (GridView) findViewById(R.id.grid);
g.setAdapter(adapter);
...

But I can not see the gridview on the display...

Thanks.

Re: [android-developers] Re: postDelayed vs. post

[Dianne Hackborn]

You should be concerned with much more than having the ANR dialog.  The ANR
dialog happens after *5 seconds*.  That is an insanely long amount of time,
well into the broken range.  200ms is a very long time for normal things on
the UI thread -- that is well into the territory of causing obvious glitches
and laggy response in the UI.

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

[Dianne Hackborn]

Oh and Gingerbread wasn't designed to run on anything but single CPU
systems, so that's irrelevant to the question of the base platform.  Of
course people shipping Android modify it in various ways, and the browser is
often one of the things they modify.

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.

Also it is going to help a lot if you post more about what your actual

[android-developers] javascript call from intent browser

[ag]

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

That was a bit hard to follow - maybe if you post your layout someone can
determine your issue.

It will remain responsive because older messages are processes before newer
messages, so you can't starve other messages from the queue by re-posting a
message when you handle it, even with no delay.

More important is balancing CPU use with what you are trying to do.

At 60fps one frame is 20ms, so it generally isn't useful to have a delay
smaller than that.  At the same time, if this is going on the entire time
the user is in your app, if using a delay of 20ms means you are keeping the
CPU running at near 100%, are going to much more quickly drain the battery
(and the user will see this in the battery use report).

Agree.  Love to see Google+ API download option from SDK addon too.I am 
sure it is in the plan and just take time, to develop, test, etc.

I certainly don't mind seeing the Facebook, twitter as part of SDK addon 
options also. 
Not sure if it is limit to "partner" only or open to competitors.

[android-developers] postDelayed vs. post

[Dmitry Golubovsky]

Hi,

Q1: Is post(action) equivalent to postDelayed(action, 0)?

Q2: If a view implements a never stopping cycle like this, depending
on two time parameters, N and T:

public void timerEvent() {
final class Timer implements Runnable {
public void run() {
timerEvent();
}
}
native_code(); // guaranteed to run no
longer than N msecs
postDelayed(new Timer(), T);
}

what combinations of N and T ranges (including T = 0) are acceptable
to make sure the view remains responsive to touch and other user-
generated events, and "force close/wait" dialog does not appear?

I currently set N to 200msec max. Any lower bound on T?

In other words, if T = 0 and a touch event arrived while in native
code, will it be processed by the view at all, or is it necessary to
have T > 0 to guarantee that touch event will be processed?

Thanks.

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

[Pratik Prajapati]

Dear All,

For production of the device, android APKs needs to be signed. I have
created keystore as explained in
http://developer.android.com/guide/publishing/app-signing.html and signed my
APKs with that keystore.

I am doing it for eclair.

I need to know following things.

(1) Do I need to sign the andoird framework build as well, apart from APKs
that I'll provide in my production device? the older guidelines say it.
http://www.kandroid.org/online-pdk/guide/release_keys.html

(2) Is there any difference between APK signing and APK certificate?

(3) Any thing else I need to do for signing and certificate?

Thanks in advance.

Regards,
Pratik

The class mentioned by 'Native registration unable to find class '...'
is always different but always seems to be a core part of Android.
When one avd goes bad like this, other avd's based on the same
platform version still work fine. Restarting the avd with wipe data
does no good. The only way to deal with it is to delete the avd and
recreate it.

Does anyone else see this? It's very annoying to have to stop and
recreate the avd.

[blake]

IANA, the Internet Assigned Number Authority, owns port numbers.
There's a list here:

You can apply for a well known port if you need.  More likely, though,
you would just use something that isn't already assigned...

[android-developers] Re: How to 'delete' allocated class by 'new'??

[blake]

I think what Damien is trying to tell you is that you are asking the
wrong question.  There is no way, in Java, to force the "deallocation"
of a specific object.  If you remove all references to it, it is, as
far as your program is concerned, gone.  Is there a reason that you
would care whether about whether it exists or not?

[android-developers] Re: AbsoluteLayout

[rich friedel]

Am I a naughty boy for wanting to use AbsoluteLayout? 

Not if you need it... do you *really* need it or will RelativeLayout work 
better?
Here is a good article discussing this topic...
http://developer.android.com/resources/articles/layout-tricks-efficiency.html

 Also, is there a way to make Eclipse stop crossing out my layout code? 

Don't use depreciated classes, methods, etc...

Also, understand that ALL iPhones have, more or less, a fixed screen 
size/density. With Android you might have one device where the screen 
density is small and one where it is huge. Imagine what you app will look 
like on not only a very low end device (MetroPcs Huwai Ascend) or on a 10+" 
tablet. Will it look the same, or as 'the same' as you can get?

[android-developers] layout's views drawing

[Stanley Orlenko aka Smith]

hi
FrameLayout contains 2 views.
frameLayout.add(view1);
frameLayout.add(view2);

view2 extends GLSurfaceView. view2 is curling page (like a page in a
book), when user is curling page view2 view1 should appears under
view2 (like next page in a book). view2 - current page, view1 - next
page.
There is problem. Sometimes view1 appears on the screen before view2
on a very short period of time and then view2 appears, it looks like a
blink. Sometimes when user is curling view2 view1 has not yet been
drawn and appears after some period of time, it looks like delay.
If I understand correctly sometimes firstly android draws view1, and
sometimes firstly android draws view2. How can I solve this problem?
Layout should appears only when view2 has been drawn and view1 should
appears immediately after user starts curling view2

Also I have a suspicious that android starts drawing view1 only when
user starts curling view2 because of view1 appears on the screen. but
if view1 is complex view with a lot of custom elements it will take a
time to draw it, as result delay...
Thanks in advance

[android-developers] Re: Please point a noob in the right direction.

[rich friedel]

btw I forgot to put the super call in the onStart() method... so it should 
look like this instead:

@Override

public void onStart() {

super.onStart();

Button toggleButton = (Button)findViewById( R.id.toggleButton );


toggleButton.setOnClickListener( new View.OnClickListener() {


public void onClick( View v ) {

// Do some click stuff here...

}

} );

}

Hello, and I hope you are having fun learning! :)

I took your code and quickly cleaned it up for you. I didn't test it so I 
don't know if anything i've done helped. BUT you had a lot of stuff in there 
that I would be surprised if it even compiled. I wrote comments explaining 
my changes...

Hope it helps

private AudioManager mAudioManager;

private boolean  mPhoneIsSilent;


// Use something else besides a reserved word for naming your fields, 
methods, classes, etc...

// Also you don't need this boolean. You can simply use 'false' or 
'true'

// private boolean False;


/** Called when the activity is first created. */

@Override

public void onCreate( Bundle savedInstanceState ) {

super.onCreate( savedInstanceState );

setContentView( R.layout.main );


mAudioManager = (AudioManager)getSystemService( AUDIO_SERVICE );

checkIfPhoneIsSilent();


// You can wrap your listener with a method however, I find it is 
better to init my

// listeners in the onStart method. See the Activity lifecycle

// Example below in the onStart() method...

// setButtonClickListner();


Log.d( "SilentModeApp", "This is a test" );

}


@Override

public void onStart() {

Button toggleButton = (Button)findViewById( R.id.toggleButton );


toggleButton.setOnClickListener( new View.OnClickListener() {


public void onClick( View v ) {

// Do some click stuff here...

}

} );

}


// I have no idea why this is here??? You perform the check in your 
checkIfPhoneIsSilent()

// {if (mPhoneIsSilent)

// {

// mAudioManager

// .setRingerMode(AudioManager.RINGER_MODE_NORMAL);

//

// mPhoneIsSilent = False;

// }

// else

// {

// mAudioManager

// .setRingerMode(AudioManager.RINGER_MODE_SILENT);

// boolean True = false;

// mPhoneIsSilent = True;

// }


/**

 * Toggles the UI images from silent to normal and vice versa.

 */

void toggleUi() {

ImageView imageView = (ImageView)findViewById( R.id.phone_icon );

Drawable newPhoneImage;


if( mPhoneIsSilent ) {

newPhoneImage = getResources().getDrawable( 
R.drawable.phone_silent );

} else {

newPhoneImage = getResources().getDrawable( R.drawable.phone_on 
);

}

imageView.setImageDrawable( newPhoneImage );

}

private void checkIfPhoneIsSilent() {

int ringerMode = mAudioManager.getRingerMode();

} else {

}

}

Re: [android-developers] Android code for capturing continious images

[Chi Kit Leung]

Using a while loop, then using
takePicture(Camera.ShutterCallback
 shutter, 
Camera.PictureCallback
 raw, 
Camera.PictureCallback
 jpeg) in camera object

It may help.
I have not tried that at all, I did the research on API doc, that may help.

Something like:

Linkify.addLinks(string, Linkify.WEB_URLS);

I have been working on a small project that involved using a Nexus S and

everything running:

They gave you LogCat output.

They appear to have only given you warnings and errors. There are
other logging levels that they did not supply you.

They appear to have broken firmware, considering that
com.android.internal.app.ResolverActivity is part of the operating
system and therefore should not need to be registered in the manifest:

http://www.google.com/codesearch#cZwlSNS7aEw/frameworks/base/core/java/com/android/internal/app/ResolverActivity.java

If they are going to hand you crash logs with no means of reproducing
whatever they created, that's not going to be especially useful.

[android-developers] ListView Data disappears

[RobinDroid]

Dear All,

I have a listview  with checkbox.
I have a menu which makes the list hide/unhide the checkbox.
When i hit my menu 3 to 4 times with hide and unhide the checkbox, the
data in listview disappears?
Why is this happening?
