问题
I am getting this crash when I play video on videoView in Android version 4.2.1. I found this out specifically on Micromax Canvas A210 device. It is not showing any message where the error is occurring. Is this a bug or something wrong in application? The crash log is as below:

回答1:
Are you a developer and using Video View in you application. If so try to debug and verify that you provide a valid uri/url to the Video View. Though there is a null check in the openVideo() of the android.widget.VideoView class, the uri may be empty string.
Here is the source of the Video View class for the android version you mentioned.

I had the same problem and found that it is a micromax specific bug while using videoview. here's an alternate way to do it using "TextureView" in android
BackGroundVideo.java
public class BackGroundVideo extends AppCompatActivity implements TextureView.SurfaceTextureListener {
ProfileTracker profileTracker;
private MediaPlayer mMediaPlayer;
private TextureView mTextureView;
private static final String TAG = sus.class.getName();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_layout);
initView();
}
private void initView() {
mTextureView = (TextureView) findViewById(R.id.play_video_texture);
// SurfaceTexture is available only after the TextureView
// is attached to a window and onAttachedToWindow() has been invoked.
// We need to use SurfaceTextureListener to be notified when the SurfaceTexture
// becomes available.
mTextureView.setSurfaceTextureListener(this);
}
@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {
Surface surface = new Surface(surfaceTexture);
mMediaPlayer.prepareAsync();
// Play video when the media source is ready for playback.
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.start();
}
});
} catch (IllegalArgumentException e) {
Log.d(TAG, e.getMessage());
} catch (SecurityException e) {
Log.d(TAG, e.getMessage());
} catch (IllegalStateException e) {
Log.d(TAG, e.getMessage());
} catch (IOException e) {
Log.d(TAG, e.getMessage());
}
}
@Override
public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {
}
@Override
public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
return false;
}
@Override
public void onSurfaceTextureUpdated(SurfaceTexture surface) {
}
}
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:keepScreenOn="true"

<TextView

android:id="@+id/te"

android:layout_centerHorizontal="true"
android:layout_marginTop="122dp" />
</RelativeLayout>
splash_layout.xml
Hope this works for you!
