If you really need to create separate tasks (which I doubt, this is a very rare case), then you need to do the following:

• If you want each task to show up in the list of recent tasks, then you will need a way for the user to differentiate. To do this you should provide a different icon for each <activity> (using android:icon="") and/or a different label for each <activity> (using android:label="").

• If you only want one task to show up in the list of recent tasks, then you need to set the following on the other <activity> tags in the manifest:

  android:excludeFromRecents="true"
