java.lang.StringIndexOutOfBoundsException mientras se reproduce video en videoView: Android v 4.2.1

Question

Recibo este bloqueo cuando reproduzco video en videoView en la versión 4.2.1 de Android. Descubrí esto específicamente en el dispositivo Micromax Canvas A210. No muestra ningún mensaje donde se está produciendo el error. ¿Es esto un error o algo mal en la aplicación? El registro de fallos es el siguiente:

Answer 1

¿Eres un desarrollador y estás usando la vista de video en tu aplicación? Si es así, intente depurar y verifique que proporcione un uri / url válido para la vista de video. Aunque hay una verificación nula en el openVideo () de la clase android.widget.VideoView, el uri puede ser una cadena vacía.

Aquí está la fuente de la clase Video View para la versión de Android que mencionó.

Answer 2

Tuve el mismo problema y descubrí que se trata de un error específico de micromax durante el uso de videoview. Aquí hay una forma alternativa de hacerlo usando "TextureView" en 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) {
}

}

¡Espero que esto funcione para usted!
