Hi All,
I am trying to make an application which can access the
MediaPlaybackService , so I have copied the IMediaPlaybackService.aidl
in my app's com.android.music path and tried to bind with the
MediaPlaybackService as below .
public class TestMusicPlaybackAppService extends Service {
/* Description for playback service interface */
IMediaPlaybackService mPlaybackService = null;
public TestMusicPlaybackAppService() {
System.out.println("TestMusicPlaybackAppService() constructor
call");
}
@Override
public void onCreate() {
super.onCreate();
System.out.println("Service onCreate() call!");
if (mPlaybackService == null) {
Intent i = new Intent();
i.setClassName("com.android.music","com.android.music.MediaPlaybackService");
System.out.println("Binding to MediaPlaybackService.");
bindService(i, connection, Context.BIND_AUTO_CREATE);
}
}
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
// Create ServiceConnection to existing MediaPlaybackService
ServiceConnection connection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder
service) {
mPlaybackService =
IMediaPlaybackService.Stub.asInterface(service);
System.out.println("MediaPlaybackService is connected!");
try {
System.out.println("Album Id:
"+mPlaybackService.getAlbumId());
System.out.println("Album
Name:"+mPlaybackService.getAlbumName());
System.out.println("Artist
Name:"+mPlaybackService.getArtistName());
System.out.println("IsPlaying:"+mPlaybackService.isPlaying());
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public void onServiceDisconnected(ComponentName name) {
mPlaybackService = null;
System.out.println("MediaPlaybackService is
disconnected!");
}
};
}
But this code is generating securtiy exception "Not allowed to bind to
service Intent { cmp=com.android.music/.MediaPlaybackService }"

Could some one tell me what is missing in my code ? Should I need to
add any permission tag in the manifest file ?
Thanks.
