android 이어폰(헤드셋) 끼었을때 이벤트 받기

You can see if AudioManager gives you the status information you're looking for:

http://developer.android.com/reference/android/media/AudioManager.html

Also look here:

http://developer.android.com/reference/android/content/Intent.html#ACTION_HEADSET_PLUG

// Register receiver
    this.registerReceiver(new BroadcastsHandler(), new IntentFilter(Intent.ACTION_HEADSET_PLUG));

Now the code of BroadcastReceiver:

public class BroadcastsHandler extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    if (intent.getAction().equalsIgnoreCase(Intent.ACTION_HEADSET_PLUG)) {
        String data = intent.getDataString();
        Bundle extraData = intent.getExtras();

        String st = intent.getStringExtra("state");
        String nm = intent.getStringExtra("name");
        String mic = intent.getStringExtra("microphone");
        String all = String.format("st=%s, nm=%s, mic=%s", st, nm, mic);


        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setTitle("Headset broadcast");
        builder.setMessage(all);
        builder.setPositiveButton("Okey-dokey", new DialogInterface.OnClickListener() {

            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        builder.create().show();
    }
}

The code is wrong!

"state" and "microphone" is integer, not string. So the code should be modified as following:

    int st = intent.getIntExtra("state" , -1);
    String nm = intent.getStringExtra("name");
    int mic = intent.getIntExtra("microphone", -1);
    String all = "st="+Integer.toString(st)+" nm="+nm+" mic="+Integer.toString(mic);
