        <!-- Drawable to draw selectively within the inset areas when the windowBackground

             has been set to null. This protects against seeing visual garbage in the

             surface when the app has not drawn any content into this area. One example is

             when the user is resizing a window of an activity that has

             {@link android.R.attr#resizeableActivity} set for multi-window mode. -->

         at the same time.

         <code>targetSdkVersion</code> lesser than {@link android.os.Build.VERSION_CODES#N} and

         <code>true</code> otherwise.

         <p>Setting this flag to <code>false</code> lets the system know that the app may not be

         tested or optimized for multi-window environment. The system may still put such activity in

         multi-window with compatibility mode applied. It also does not guarantee that there will be

         no other apps in multi-window visible on screen (e.g. picture-in-picture) or on other

         displays. Therefore, this flag cannot be used to assure an exclusive resource access.

         <p>NOTE: A task's root activity value is applied to all additional activities launched in

         the task. That is if the root activity of a task is resizeable then the system will treat

         all other activities in the task as resizeable and will not if the root activity isn't

         Value needs to be greater or equal to 1.0, otherwise it is ignored.

         <p>

         NOTE: This attribute is ignored if the activity has

         {@link android.R.attr#resizeableActivity} set to true, since that means your activity

         supports any size. -->

         {@link android.R.attr#resizeableActivity} set to true. -->

    <!-- This value indicates the minimum aspect ratio the activity supports. If the app runs on a

         Value needs to be greater or equal to 1.0, otherwise it is ignored.

         NOTE: This attribute is ignored if the activity has

         {@link android.R.attr#resizeableActivity} set to true, since that means your activity

         supports any size. -->
