I'm trying to send DTMF tones when Call waiting event arriving. I use a toneGenerator = new ToneGenerator (AudioManager.STREAM_VOICE_CALL, toneVolume) as the DTMF tone. But if user set the the In-Call Volume to minimum by the hardware volume key, It cannot hear the Call wating tone. I think this is not a right scenario if the Call wating tone is also muted.
If I set other audio type to the ToneGenerator, It seems also cant guarantee that the volume of such audio type is not zero. Is it possible to have a audio type for Call wating event or an interface to set individual volume to one ToneGenerator? Or is there any way to prevent the Call wating tone be muted? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "android-framework" group.
