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

Answer 1

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

/**
 * Checks whether a wired headset is connected or not.
 * 
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;
}
