How to disable headset detection in android programmatically?

Question

I am working on an audio routing app which can direct audio between either headset and/or speaker of a phone. Is there any way I can programmatically stop headset detection?

EDIT: I am using a wired headset.

Answer 1

When you say "handset", do you mean "wired headset"? If so, there's an intent to detect whether or not one is being plugged or unplugged: ACTION_HEADSET_PLUG.

To check the status, you can use AudioManager.isWiredHeadsetOn(), although that may return false if there is also a bluetooth headset, and audio is routed to that instead.

Like in this manner:

final AudioManager audio =(AudioManager)getApplicationContext().getSystemService(AUDIO_SERVICE);
if(audio.isWiredHeadsetOn())
            {
                audio.setWiredHeadsetOn(false);
                audio.setSpeakerphoneOn(true);


            }

But before that

So, You might write this code in "AndroidManifest.xml"

<receiver android:name="com.juno.brheadset.HeadsetStateReceiver">
    <intent-filter>
        <action android:name="android.intent.action.HEADSET_PLUG"/>
    </intent-filter>
</receiver>-->

But, This doesn't work. When OS send this "HEADSET_PLUG" intent, OS set the flag "Intent.FLAG_RECEIVER_REGISTERED_ONLY" So, You should write the code like below in Activity or Service class instead of "AndroidManifest" things.

public class BRHeadsetActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    IntentFilter receiverFilter = new IntentFilter(Intent.ACTION_HEADSET_PLUG);
    HeadsetStateReceiver receiver = new HeadsetStateReceiver();
    registerReceiver( receiver, receiverFilter );


}

In this way you can solve this problem.
