Mixing
Handling volume buttons with screen locked
1
Currently, I'm working on my simple android studio script, and I must use volume down while the mobile screen is locked.
Please, take a look at my script:
public class MainActivity extends AppCompatActivity {
public MediaPlayer mediaPlayer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final BroadcastReceiver vReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
initAudio(getApplicationContext(), "https://www.w3schools.com/html/horse.mp3");
}
};
registerReceiver(vReceiver, new IntentFilter("android.media.VOLUME_CHANGED_ACTION"));
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
event.startTracking();
initAudio(getApplicationContext(), "https://www.w3schools.com/html/horse.mp3");
return true;
}
return super.onKeyDown(keyCode, event);
}
public void initAudio(final Context context, String url) {
if (mediaPlayer == null) {
try {
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer = MediaPlayer.create(context, Uri.parse(url));
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
killMediaPlayer();
}
});
mediaPlayer.start();
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(context, "Fail", Toast.LENGTH_LONG).show();
killMediaPlayer();
}
}
}
public void pauseAudio() {
if (!(mediaPlayer == null)) {
mediaPlayer.pause();
}
}
public void startAudio() {
if (!(mediaPlayer == null)) {
mediaPlayer.start();
}
}
public void killMediaPlayer() {
if (mediaPlayer != null) {
try {
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer = null;
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
What should I do to fix this issue? There are no errors, the script only works when I'm with my screen unlocked.
Can you help me with this?
Thank you very much.
