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?

Solution 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 +

Solution 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;
    }

Solution 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()+"");

the permission. that must be why it didn't work the first time i tried that solution. is there a way to do that without involving Context?

[Naskov]

@dosse91214 what is wrong with the permission? If you don't add the permission the isWiredHeadsetOn() always will return false.

[dosse91214]

yes that's what i meant. the first time i tried this solution it didn't mention that i had to add the permission. thanks :D

Great except that this method was deprecated in API 14 - developer.android.com/reference/android/media/…

[maid450]

@Phil under the deprecation info it says Use only to check is a headset is connected or not. and that's exactly for what he wants to use it.

[Naskov]

@maid450 as Sood said, "So I guess it is okay to keep using it to check whether or not a wired headset is connected, but not to check whether or not audio is being routed to it or played over it.".

[Phil Haigh]

@maid450 Point taken but it is bad engineering practice to write new code to use a deprecated API when there are non-deprecated solutions available.

[Phil Haigh]

@Naskov I think not. If you want the credit, you need to post your solution, not mine.

[Naskov]

@Phil Stackoverflow is not about who will take the credits, it's about helping other people and sharing knowledge. I don't care about the rating. Feel free to post that as an answer instead of telling me the solution and I will ping the owner of this thread to accept your answer.

[Phil Haigh]

@Naskov the asker has already identified the only reliable solution - using a BroadcastReceiver.

[zionpi]

The method isWiredHeadsetOn() from the type AudioManager is deprecated

[Sasha Shpota]

This would work only staring from API level 23. Any idea how to use it for lover API levels, say 19?

[Elliptica]

How would you do this with the new phones that require headphone converters that plug in through the usb port? This command and the one below always return false with that.
