已弃用的 AudioManager.isWiredHeadsetOn 的替代方案？

方法AudioManager.isWiredHeadsetOn() http://developer.android.com/reference/android/media/AudioManager.html#isWiredHeadsetOn%28%29从 API 级别 14 开始已弃用，现在我们如何检测有线耳机是否已连接？

这是我的解决方案：

private boolean isHeadsetOn(Context context) {
    AudioManager am = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);

    if (am == null)
        return false;

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
        return am.isWiredHeadsetOn() || am.isBluetoothScoOn() || am.isBluetoothA2dpOn();
    } else {
        AudioDeviceInfo[] devices = am.getDevices(AudioManager.GET_DEVICES_OUTPUTS);

        for (AudioDeviceInfo device : devices) {
            if (device.getType() == AudioDeviceInfo.TYPE_WIRED_HEADSET
                    || device.getType() == AudioDeviceInfo.TYPE_WIRED_HEADPHONES
                    || device.getType() == AudioDeviceInfo.TYPE_BLUETOOTH_A2DP
                    || device.getType() == AudioDeviceInfo.TYPE_BLUETOOTH_SCO) {
                return true;
            }
        }
    }
    return false;
}
