Hi, Android programmers,
Every day I struggled with a problem that seems strange and without a solution. What I'm looking for are some recommendations and some previous impressions. For testing, I have a Motorola Xoom , a Galaxy Nexus Tab tab , a Galaxy Nexus phone, and a Galaxy Tab 10.1 .
The main test application is developed for / in the Galaxy Tab 10.1 . The application is very simple. Pressing a button → start a video.
The app works great on Beans jelly devices. But on 3.1 devices, I can only hear audio until a video appears.
To fix the problem, I created a grid with many different codecs / resolutions, but this does not seem to affect playback (still only audio and without video).
Of course, the application runs smoothly on a Beans jelly phone and tablet.
Does anyone have previous experience with Xoom and / or Galaxy Tab 10.1?
Just in case, some might think that the problem with my code is here:
VideoView v[];
@Override
public void onCreate(Bundle savedInstanceState) {
super.MENU_HELP = true;
super.BACK_ACTIVATED =true;
super.onCreate(savedInstanceState);
setContentView(R.layout.video_view);
String fileName[] = {
"v1.mkv",
"v2.m4v",
"v3_mpg4.m4v",
"v4.m4v",
"v5_and_mid.m4v",
"v6_ipad.m4v",
"v7_ipod.m4v",
"v8.m4v",
"v9.mp4"};
v = new VideoView[9];
v[0] = (VideoView) findViewById(R.id.v1);
v[1] = (VideoView) findViewById(R.id.v2);
v[2] = (VideoView) findViewById(R.id.v3);
v[3] = (VideoView) findViewById(R.id.v4);
v[4] = (VideoView) findViewById(R.id.v5);
v[5] = (VideoView) findViewById(R.id.v6);
v[6] = (VideoView) findViewById(R.id.v7);
v[7] = (VideoView) findViewById(R.id.v8);
v[8] = (VideoView) findViewById(R.id.v9);
String root = Environment.getExternalStorageDirectory().toString();
for (int i=0; i<9; i++) {
v[i].setVideoPath(root + "/Videos/" + fileName[i]);
v[i].start();
}
}

EDIT2:
Adding the following line after configuring VideoView:
Log.i("MyVP", "" + v.isOpaque() + " " + v.isEnabled() + " " + v.isPlaying() + " " + v.isShown());
it shows false true false false
I tried changing the Alpha VideoView and the root view, but the result is still the same.
PS: Almost all files (compatible) can be opened using the Video Player application built into Android. But I need to play them inside the application ...
