Disable sound just for one application

Question

Is it possible to turn off all sounds of just one app and to save the choice until the next start of the app?

So I have a ToggleButton at the StartActivity and by pressing this Button, all sounds of the app should be deactivated, but sounds of other apps should still be working.

I tried it with Preferences, using the SharedPreferences class, an xml file and so on, like in my book. But going through the introduction i realized, that the Preferences are just a way to save data permanent. So I would have to include for example on every Button with a sound an if-clause that checks if this or that saved preference for sound on/off is true/false and then activates/deactivates the sound?

I thought that it could be easier?

Answer 1

Actually, if you want to disable a sound in your application - you can just don't play it. You can store the flags for each sound you want to play in the SharedPreferences and check it every time you want to play a sound. It's really easy!

Answer 2

You can probably write your own MyButton class that extends Button and override onClick.

Answer 3

1. Declare a string

   String strSound;

2. enter this line in your shared preference settings

   strSound = prefs.getString("sound", "on");

3. enter this line in your onActivityResult

   strSound = prefs.getString("sound", "on");

4. put this lines in your media player which is used to give sounds for your application

   private void playSound()
   {
   mp = MediaPlayer.create(MyActivity.this, R.raw."your_soundfile_name");
   
   mp.setOnCompletionListener(new OnCompletionListener() 
   {
       @Override
       public void onCompletion(MediaPlayer mp) 
       {
           mp.release();
       }
   }); 
   if(strSound.equals("on"))
   mp.start();
   

5. now put this lines on your toggle button activity

   your_togglebutton_id.setOnCheckedChangeListener(new     CompoundButton.OnCheckedChangeListener()
   {
       public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
       {
           prefs = getSharedPreferences(prefName, MODE_PRIVATE);
           SharedPreferences.Editor editor = prefs.edit();
           if (isChecked)
           {
               editor.putString("sound", "on");
               editor.commit();
           }
           else
           {
               editor.putString("sound", "off");
               editor.commit();
           }
       }
   }
