Re: [android-developers] Simple code that works in 3.0 but not in 2.3.3 (with support lib)

[Gink Labrev]

I found the cause. If the activity extends FragmentActivity, the code above
works in 2.3.3, but if it extends ActionBarActivity it does not work.

Does someone know how to solve it ?

This ActionBarCompat has a lot of bugs !! Maybe it is best to return to
ActionSherlockBar.

Hi,

Why does the simple code below work in Android 3.0, but not in 2.3.3 ???
In 2.3.3, it shows only a blank screen.
Any help would be appreciated.

*import android.os.Bundle;*
*import android.support.v4.app.ListFragment;*
*import android.widget.ArrayAdapter;*

*public class TestListFragment extends ListFragment {*
*
*
* *

* private String[] data = {"One", "Two", "Three"};*
* *
* @Override*
* public void onActivityCreated(Bundle savedInstanceState) {*

* myAdapter = new ArrayAdapter(getActivity(),
android.R.layout.simple_list_item_1, data);*

Does Android implement the Java API for WebSocket (JSR-356) ?

http://docs.oracle.com/javaee/7/tutorial/doc/websocket.htm
http://jcp.org/aboutJava/communityprocess/final/jsr356/index.html

If not, is there a component that allows to use Websockets in Android ?

Re: [android-developers] As close my android application

[Gink Labrev]

Activity.finish()?
http://developer.android.com/reference/android/app/Activity.html
Or you can kill the application process if you have root privileges.

[android-developers] Re: How to reduce size of JPEG Image in Android

[Gink Labrev]

Hi,

I think the code below can help:

private byte[] compressPhoto(Bitmap bm) {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bm.compress(CompressFormat.JPEG, 75, bos);
return bos.toByteArray();
}

Cordially,
Gink

Re: [android-developers] what's layout-sw680dp-w1000dp means?

[Gink Labrev]

I never heard of it
The official documentation about supporting multiple screens can be found
here:
http://developer.android.com/guide/practices/screens_support.html#DeclaringTabletLayouts


it does not mention  swdp-wdp schema, only swdp or wdp.
