How to simulate killing activity to conserve memory?

Question

Android doc say:

\"When the system, rather than the user, shuts down an activity to conserve memory, ... \"

But how to simulate

Answer 1

To debug onRestoreInstanceState you could do the following:

• make sure you can debug application right after its start (calling android.os.Debug.waitForDebugger() from your constructor helps, it hangs your application until debugger is connected),

• put you application in some state,

• causally kill it from Settings->Apps,

• causally switch back to it through Recent Apps button (it will still be in the list),

• at this moment your application will be started anew and onRestoreInstanceState will be immediately called on the top activity.
