Could anyone explain why?
Just because your activity is being destroyed to reclaim memory does not mean the process is going away. Java uses garbage collection, and the Dalvik VM apparently has some hooks to allow the VM to return memory to the OS on occasion. Hence, if Android destroys your activity, and GC reclaims your activity's memory, that memory can be used by others. > Here is the link describe activity life cycle, always kill process > before running onCreate() > http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle You will notice that there are other paths in that diagram that cause your activity to be destroyed that do not involve terminating the process. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _Android Programming Tutorials_ Version 1.1 Available!
