Does anybody know if there is a way to set incoming call ringtone volume increasing from low to high programmatically from Android application? Any suggestions are appreciated.
You could call to getStreamMaxVolume(RingTone) to get your max volume of the ring tone.
int streamMaxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_RING);
Toast.makeText(this, Integer.toString(streamMaxVolume), Toast.LENGTH_LONG).show();
Now you have your max volume.
Then you could make some method to change the volume (with a timer, loop, random, ...)
audioManager.setStreamVolume(AudioManager.STREAM_RING,**YOURVOLUMEHERE**,
AudioManager.FLAG_ALLOW_RINGER_MODES|AudioManager.FLAG_PLAY_SOUND);
