In PlaysongActivity, override onStop() and call release() on the MediaPlayer.
This will stop playback (and release resources) when you exit that activity.

I am using the library barcodescanner from https://github.com/dm77/barcodescanner.
Currently the scanner displays a rectangle and a laser across the middle.
that looks similar to:
I am looking to make this view into a square since I am only scanning QR codes and to remove the laser and would appreciate some help.

I think I need to extend a class from the library and override some of the methods in it but I'm not sure how to do this and have the overridden methods used in my scanner class.
Thank you for your time.
Add library module in a project (not as a dependency). Here is a tutorial how to add a library module in Android Studio.
Go to library module and find in ViewFinderView.java class drawLaser(Canvas canvas) method (draws the line in the middle).
I have an android app that streams audio by URL (its an infinite stream) and it works. But I need to allow users to rewind X seconds and forward X seconds ( you can only forward if you rewind before )

I'm working on a music player for android and i'm stuck at this problem.
By now i can play a song with musicservice and send it to background, i also display a notification with current playing song.
What i need is to re-open the main activity from the song notification and continue playing the song, it actually starts the desired activity but the music service is re-created and it stops the current playing song.
Here is my code.

(The fragment also re-creates itself when navigating through drawer menu items)
I hope somebody can help me achieve this. I dont know how to maintane the state when re-starting the MainActivity (by the way, im using navdrawer to hold fragments)
Include the currently playing song in your notification intent. Update the intent as the song changes. Include the flag to clear top and the flag to update current in the notification intent. :( sorry IDK if I have the flags right for your situation but you'll have a place to do more research.
In your service where you create the notification intent.
// link the notifications to the recorder activity
Intent resultIntent = new Intent(context, KmlReader.class);
resultIntent
.setAction(ServiceLocationRecorder.INTENT_COM_GOSYLVESTER_BESTRIDES_LOCATION_RECORDER);
resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent resultPendingIntent = PendingIntent
.getActivity(context, 0, resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
return mBuilder.build();
}
Then in main onCreate check the bundle for the name of the currently playing song and display it. Notice how I check for the existence of a bundle key before using it.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = getIntent();
String intentaction = intent.getAction();
// First Run checks
if (savedInstanceState == null) {
// first run init
...
} else {
// get the saved_Instance state
// always get the default when key doesn't exist
// default is null for this example
currentCameraPosition = savedInstanceState
.containsKey(SAVED_INSTANCE_CAMERA_POSITION) ? (CameraPosition) savedInstanceState
.getParcelable(SAVED_INSTANCE_CAMERA_POSITION) : null;

I want to make a text appear in TextView when the video reaches current time. I've tried this code :
public class VideoActivity extends Activity {
private static final String MY_AD_UNIT_ID = null;
protected static final String TAG = null;
private AdView adView;
int waktu;
Button btncek;
private MediaController controller = null;
TextView textView2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.videoplayer);
Bundle bundle = getIntent().getExtras();
String urlbarus = getIntent().getStringExtra("urlbaru");
final VideoView videoView = (VideoView) findViewById(R.id.videoView1);
videoView.setVideoPath(urlbarus);
MediaController.MediaPlayerControl mcEvents = new MediaController.MediaPlayerControl() {
public void start() {
videoView.start();
}
public void seekTo(int pos) {
videoView.seekTo(pos);
}
public void pause() {
videoView.pause();
}
public boolean isPlaying() {
return videoView.isPlaying();
}
public int getDuration() {
return videoView.getDuration();
}
public int getCurrentPosition() {
return videoView.getCurrentPosition();
}
public boolean canSeekForward() {
return true;
}
public boolean canSeekBackward() {
return true;
}
public boolean canPause() {
return true;
}
#Override
public int getBufferPercentage() {
// TODO Auto-generated method stub
return 0;
}
};
controller = new MediaController(this);
controller.setMediaPlayer(mcEvents);
controller.setAnchorView(findViewById(R.id.wrapper));
videoView.start();
if(mcEvents.getCurrentPosition()>=10000){
textView2.setText("kebaca");
}
#Override
public boolean onTouchEvent(MotionEvent event) {
//the MediaController will hide after 3 seconds - tap the screen to make it appear again
controller.show();
return false;
}
This is the code for showing text :
if(mcEvents.getCurrentPosition()>=10000){
textView2.setText("kebaca");
}
I have tried that code, but nothing happens (textview2 does not show the text)
Can anyone help me?
Try something like..
final MediaController.MediaPlayerControl mcEvents = ....
textView2.setText(""); // edited
new Thread(new Runnable() {
#Override
public void run() {
while (mcEvents.getCurrentPosition()<10000){
try {
Thread.sleep(1000);
} catch (InterruptedException ignored) { }
}
runOnUiThread(new Runnable() {
#Override
public void run() {
textView2.setText("kebaca");
}
});
}
}).start();
