Clear all recent tasks Programmatically

I am trying to remove all recent tasks through a program. Before posting a question, I googled it, but no luck at all.

I tried to use ActivityManager.killBackgroundProcess(pckagename), but it also does not remove the task from a recent task list.

I also tried the link Android, how to clear the recent task list which could get from Home button in most phone? Reflection is a possible way?

I always get the following exception

java.lang.SecurityException: Permission Denial: removeTask() from pid=23297, uid=10051 requires android.permission.REMOVE_TASKS

Even if I already specified the android.permission.REMOVE_TASKS permission in the manifest.

How can we clear the list of recent tasks programmatically, so that the user can see no recent tasks in a recent task list?

Try this out in android manifest inside the launcher activity:

 android:excludeFromRecents="true"

In your AndroidManifest.xml, you need to add this:

uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES"

I just met with the same problem. My duty was to remove a 3th party app from recent list.

Okay, I don`t know how clear the recent list, but I know, how not to put your app there. start it with: FLAG_ACTIVITY_NO_HISTORY flag .

This worked for me, I hope I can help with it for you. details: min SDK level 14

Cheers,

REMOVE_TASKS is a signature-level permission. It can only be held by apps written by the developers of the device firmware, such as a device manufacturer or ROM mod author.
