How to avoid Activity not started, its current task has been brought to the front warning?

If u want to enforce it do this.

Android device and emulator - Warning: Activity not started, its current task has been brought to the front

You normally get that warning when your app is already running on the device (physical or emulated).

To get the device chooser:

(Menu item) Run, Run configurations, (Left pane) choose your app name, (Tab) choose Target, select "Always prompt", Apply, Close.

Since now on, for that app, you'll be propted to choose a running device or to start one.
