Android – remove apps from recent apps

I'm developing an android app. If I close my app, my app will be available in the recent apps list. Now I don't want to display it in the recent apps list. How to programmatically close my app and how to remove it from the recent apps list. Please share your suggestions

resolvent:

In manifest.xml, set the following as the root activity

<activity
    android:name=".Your_Root_Activity_Name"
    android:excludeFromRecents="true"
    .... 
</activity>

Depending on the result, you may also have to use the Android: nohistory = "true" attribute. But you're not sure if you need it in your case
