How to check and redirect audio between wired headset and speaker phone?

Question

I am developing a simple app , that should toggle between speaker phone and wired headset to play audio on a button click event. I am trying to make use of isWiredHeadsetOn() function, but it says that this is deprecated for Android API lvl 5 onwards. So how do I check if currently audio is playing or not through wired headset so that I can redirect it to the phone speaker?

Note: I start my app with the headphone plugged to the 3.5mm jack of the phone.

This is my attempt at the code so far:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_audio_re_direct);
    redirect = (Button)findViewById(R.id.redirect);
    final AudioManager audio =(AudioManager)getApplicationContext().getSystemService(AUDIO_SERVICE);

    redirect.setOnClickListener(new View.OnClickListener() {

        @SuppressWarnings("deprecation")
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            if(audio.isWiredHeadsetOn())
            {
                audio.setWiredHeadsetOn(false);
                audio.setSpeakerphoneOn(true);
                Toast.makeText(getApplicationContext(), "SpeakerPhone On", Toast.LENGTH_LONG).show();
                redirect.setText("Turn on headset");

            }
            else 
            {
                audio.setSpeakerphoneOn(false);
                audio.setWiredHeadsetOn(true);
                Toast.makeText(getApplicationContext(), "Wired Headset On", Toast.LENGTH_LONG).show();
                redirect.setText("Turn off headset");
            }

            }

    });
        }

But the app is not toggling at all. Initially it detects that the wired headset is present, shows the Toast message SpeakerPhone On and that's it. It does not toggle between the two.

Someone please help me to make this work. Thanks.

Well, `setWiredHeadsetOn` has been deprecated since API level 5 so it won't work. — ChuongPham, Jan 07 '14 at 05:24
You can browse the source codes for the `AudioManager` and `TelephonyManager` classes and then use Reflection to do what you want. I don' t have an example of Reflection utilising these classes but you can search SO for an example. — ChuongPham, Jan 07 '14 at 05:53

you have to register a receiver for ACTION_HEADSET_PLUG intent and make a receiver class to catch that broadcast from that you can implement your own logic please check this

Finally managed to solve my own problem using this work around (as suggested by @noelicus):

I wonder if you got redirect the audio input (microphone device) to MIC headphones because I would like that when it was connected to the 3.5mm jack something that redirigiese input and output audio to headphones.

AudioManager mAudioMgr = (AudioManager)getSystemService(Context.AUDIO_SERVICE);

        mVolumeButton = (Button)findViewById(R.id.btn_Volume);
        mVolumeButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(mAudioMgr.isWiredHeadsetOn()){

                    mAudioMgr.setWiredHeadsetOn(false);
                    mAudioMgr.setSpeakerphoneOn(true);
                    mAudioMgr.setMode(AudioManager.MODE_IN_COMMUNICATION);

                    Toast.makeText(getApplicationContext(), "SpeakerPhone On", Toast.LENGTH_LONG).show();
                }else{
                    mAudioMgr.setMode(AudioManager.MODE_IN_COMMUNICATION);
                    mAudioMgr.setSpeakerphoneOn(false);
                    mAudioMgr.setWiredHeadsetOn(true);
                    Toast.makeText(getApplicationContext(), "Wired Headset On", Toast.LENGTH_LONG).show();
                }
            }
