Android task killer

Question

Im trying to write a simple task killer. I know I shouldnt kill tasks in Android, but Im eager to try something like this. I have the following code:

List<         


        

Answer 1

To achieve best result form killProcess , try calling killProcess many times.as

for (int i = 0; i < 10; i++)
{
 android.os.Process.killProcess(procInfo.get(i).pid);
}

NOTE:

version ２.２ - killBackgroundProcesses : " This is the same as the kernel killing those processes to reclaim memory; the system will take care of restarting these processes in the future as needed."

ActivityManager am = (ActivityManager)getSystemService(ACTIVITY_SERVICE);
am.killBackgroundProcesses("com.est.testetst");

Required Permissions:

android.Manifest.permission.KILL_BACKGROUND_PROCESSES

version ２.１ - restartPackage -" This method is deprecated. (works for version less than 2.2. This is now just a wrapper for killBackgroundProcesses(String); the previous behavior here is no longer available to applications because it allows them to break other applications by removing their alarms, stopping their services, etc."

 ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    am.restartPackage(getPackageName());

Required Permissions:

<uses-permission android:name="android.permission.RESTART_PACKAGES" />

Answer 2

Fortunately, killProcess() will only work for you to kill your own processes. You can tell this by reading the documentation.

Answer 3

You can't kill other tasks that way because the Kernel will enforce permissions. Try this instead:

ActivityManager activityManager = (ActivityManager) context.getSystemService("activity");
activityManager.restartPackage(packageName);

you will need the following permissions in the manifest:

<uses-permission android:name="android.permission.RESTART_PACKAGES" />
<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" />

EDIT:

Actually restartPackage is deprecated. use killBackgroundProcesses() instead!
