  Android后台线程执行前台UI操作：

    // 解决 Can't toast on a thread that has not called Looper.prepare()
    28+ Use：getApplicationContext().getMainExecutor().execute(() -> { });
    new Handler(Looper.getMainLooper()).post(() -> {//避免用Looper.prepare()
      Toast.makeText(context, "...", Toast.LENGTH_SHORT).show(); });


  解决 AlertDialog+getApplicationContext() 报错 Unable to add window -- token null is not valid; 例外：Toast可用任何上下文及getApplicationContext()
    new AlertDialog.Builder(view.getContext()).create();// or MainActivity.this


  解决横竖屏切换阻止构建 android:screenOrientation="portrait" tools:ignore="LockedOrientationActivity" tools:replace="android:screenOrientation"
