通过编程检查android手机是否有flash

当有人下载我的应用程序时，我想通知他他的手机是否有闪光灯。请帮助我获取用于此目的的代码。

很抱歉，我现在无法升级，因为我还不熟悉堆栈溢出

Context context = this;
PackageManager packageManager = context.getPackageManager();

// if device support flash?
if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA_FLASH)) {
    //yes
    Log.i("camera", "This device has flash supported!");
}else{
    //no
    Log.i("camera", "This device has no flash support!");
}
