Question

I need to create an application that will change the bluetooth headset volume by pressing the volume up/down keys [on the phone]. While I yet don’t know how to catch the volume up/down keys, I am currently more interested in how one can change the bluetooth headset volume programmatically?

Note:
I want to have the bluetooth volume dialog one gets when using the phones volume up/down keys while making a call using bluetooth and the phones normal dialer / GSM call.

Answer 1

Find the solution spread over this three threads:

Android Bluetooth Earpiece Volume

Trigger system volume bar

Android – Volume Buttons used in my application

Don’t forget this permission:

    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /> 

Thanks to Doomsknight for the initial hint 🙂
