Donut

This application does absolutely nothing. It was originally created for Android development and testing. It is useful for testing application condition detection, app launching and killing, and auto task killer priority management.

Unlike other "nothing" apps, this actually does what is described. There is no blank window. There is no UI, and the app icon is transparent.

不像其他的“一无所有”的应用程序，这实际上是在做什么说明。有没有空白的窗口。有没有UI，应用程序的图标是透明的。</div> <div class="show-more-end">
