Check whether headphones are plugged in

Question

I can't seem to find a way to know on android if the headphones are plugged in. I found various solutions but they always seem to return false. The only thing that seems to work properly is a BroadcastReceiver, but that's not what I need:

I just need something like this

if(headphones plugged in) {
}

Is there such a function? Does it require some special permissions?

Answer 1

You can use this code for checking if the headset is plugged in

AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
audioManager.isWiredHeadsetOn();

(Don't worry about the deprecation, it's still usable for ONLY checking if the headset are plugged in.)

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

Available in Android 2.0 +

Answer 2

Use this code...

AudioManager am1 = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
Log.i("WiredHeadsetOn = ", am1.isWiredHeadsetOn()+"");
Log.i("MusicActive = ", am1.isMusicActive()+"");
Log.i("SpeakerphoneOn = ", am1.isSpeakerphoneOn()+"");

Answer 3

AudioManager.isWiredHeadsetOn() is DEPRECATED. So, you need to use AudioManager.getDevices() method instead:

private boolean isHeadphonesPlugged(){
        AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
        AudioDeviceInfo[] audioDevices = audioManager.getDevices(AudioManager.GET_DEVICES_ALL);
        for(AudioDeviceInfo deviceInfo : audioDevices){
            if(deviceInfo.getType()==AudioDeviceInfo.TYPE_WIRED_HEADPHONES
                    || deviceInfo.getType()==AudioDeviceInfo.TYPE_WIRED_HEADSET){
                return true;
            }
        }
        return false;
    }

Use Google Awareness API

It's very rich in providing contextual feeling.
