如何检测Android设备是否没有物理按键或弹幕按键？

import android.content.Context;
import android.content.pm.PackageManager;
import android.view.KeyCharacterMap;
import android.view.KeyEvent;

public class DeviceUtils {
    public static boolean hasPhysicalKey(Context context) {
        return KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_BACK);
    }

    public static boolean hasTouchScreen(Context context) {
        PackageManager packageManager = context.getPackageManager();
        return packageManager.hasSystemFeature(PackageManager.FEATURE_TOUCHSCREEN);
    }
}
