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

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;
    }

Answer 3

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 4

audioManager.isWiredHeadsetOn() is deprecated as per below code from android.media.AudioManager

/**
 * Checks whether a wired headset is connected or not.
 * <p>This is not a valid indication that audio playback is
 * actually over the wired headset as audio routing depends on other conditions.
 *
 * @return true if a wired headset is connected.
 *         false if otherwise
 * @deprecated Use {@link AudioManager#getDevices(int)} instead to list available audio devices.
 */
public boolean isWiredHeadsetOn() {
    if (AudioSystem.getDeviceConnectionState(DEVICE_OUT_WIRED_HEADSET,"")
            == AudioSystem.DEVICE_STATE_UNAVAILABLE &&
        AudioSystem.getDeviceConnectionState(DEVICE_OUT_WIRED_HEADPHONE,"")
            == AudioSystem.DEVICE_STATE_UNAVAILABLE &&
        AudioSystem.getDeviceConnectionState(DEVICE_OUT_USB_HEADSET, "")
          == AudioSystem.DEVICE_STATE_UNAVAILABLE) {
        return false;
    } else {
        return true;
    }
}

so we need to use AudioManager#getDevices method like below

private boolean isWiredHeadsetOn(){
    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;
}
