Disable the Volume Toast

Question

I'm trying to increase the volume using AudioManager.

But it showing Native Android Volume UI(Volume Seekbar) toast.I want to disable this. I know this can be possible in Activity using Key Event but i want to do it through service. How to disable the toast? Here is a screenshot of the toast:

Answer 1

The AudioManager-class offers the following methods to adjust the volume of certain streams:

• adjustVolume(int, int)
• adjustStreamVolume(int, int, int)
• adjustSuggestedStreamVolume(int, int, int)
• setStreamVolume(int, int, int)

All those methods take a flag-parameter as their last argument. The flag which is interesting for you is the FLAG_SHOW_UI which:

Show a toast containing the current volume.

So, to get rid of the Toast, don't supply this flag (or the int-value 1) but supply all your other flags (if needed) or just 0:

AudioManager manager = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE);
manager.adjustVolume(AudioManager.ADJUST_RAISE, 0);

The above code-snippet works for me on Android 4.0.4 (Motorola Xoom) and Android 2.3.5 (HTC Desire HD).
