Closing an app programmatically from own app

Question

I want to close another app opened from my app with an intent.

On my app, I create an intent to open Google Maps, but I want to close this Google Maps with a button on my app.

Is that possible?

Answer 1

It is not possible to close the another app from your app.

It is ethically not correct and there is no official Android API as well.

Answer 2

You can only close the background processes of other apps, you are no longer able to close their main activities.

Declare a permission for that in your AndroidManifest file:

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

In your app:

ActivityManager manager = (ActivityManager)getSystemService(Activity.ACTIVITY_SERVICE);
manager.killBackgroundProcesses(packageName);

I have used this code and it has worked for me.

Hope this can help you, thanks.
