Kill background processes to free up memory

1 vote · 1 comment

Basically what we do is we get a list of running apps and count them, then we check if there more than 0 apps running on the background. after than we simply check to make sure our own app isn't going to be killed after the code execution.

OPTIONAL: I Suggest using a try catch in case something goes wrong.

raw · 
copy
 · downloadActivityManager activityManager = (ActivityManager)  getActivity().getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> runAppList = activityManager.getRunningAppProcesses();
int listsize = runAppList.size();
		
if (runAppList != null) {
		for (int i = 0; i < listsize; ++i) {
			if (runAppList.get(i).pid != android.os.Process.myPid()) {
				android.os.Process.killProcess(runAppList.get(i).pid);
				activityManager.killBackgroundProcesses(runAppList.get(i).processName);
			}
		}
}

Great! but what is the minimum API level for that, does it worked on API 8 or higher?
