I'm having a question about how to control the media volume of the app.
I'm using this method:
Button button1;
MediaPlyer mp;
button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mp = MediaPlayer.create(Teste.this, R.raw.som);
mp.start();
}
});
I wanted to decrease or increase the volume on the device, I would change the app and not the phone.
Add to Activity (s) that you want the media volume to be changed instead of the buzzer method below:
@Override
protected void onStart() {
super.onStart();
setVolumeControlStream (AudioManager.STREAM_MUSIC);
}
The onStart() method references when the application starts.
There is more information on these links below:
/ a>To control the volume of your application in MediaPlayer, you can use the "setVolume" method
// Volume baixo em ambos os lados (Esquerdo e direito)
mp.setVolume(0,0)

You can use the AudioManager .
Example usage:
AudioManager audio = (AudioManager)
getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
audio.setStreamVolume(AudioManager.STREAM_MUSIC, VALOR, 0); // Valor: 0~15
