当我添加TYPE_APPLICATION_OVERLAY并在OREO中运行时出现错误，如果我在kitkat中完美运行但在oreo崩溃中运行，该如何解决我的错误... 请帮助

此代码

private static class OverlayDialog extends AlertDialog {

    public OverlayDialog(Activity activity) {
        super(activity, R.style.OverlayDialog);
        WindowManager.LayoutParams params = getWindow().getAttributes();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            params.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
        }
        else
        {
            params.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
        }
        params.dimAmount = 0.0F; // transparent
        params.width = 0;
        params.height = 0;
        params.gravity = Gravity.BOTTOM;
        getWindow().setAttributes(params);
        getWindow().setFlags(FLAG_SHOW_WHEN_LOCKED | FLAG_NOT_TOUCH_MODAL, 0xffffff);
        setOwnerActivity(activity);
        setCancelable(false);
    }

    public final boolean dispatchTouchEvent(MotionEvent motionevent) {
        return true;
    }

    protected final void onCreate(Bundle bundle) {
        super.onCreate(bundle);
        FrameLayout framelayout = new FrameLayout(getContext());
        framelayout.setBackgroundColor(0);
        setContentView(framelayout);
    }
}
