Android Question How can I use these .java files so my B4A app can send ADB commands to the same device it is on?

[JohnC]

I would like my B4A app to be able to kill another app running on the same device.

I came across this java code that would allow my app to interface with the ADB shell on the same device as my app (as if a different computer was sending an ADB command to the device):

GitHub - cgutman/AdbLib: A Java library implementation of the ADB network protocol

A Java library implementation of the ADB network protocol - cgutman/AdbLib

github.com

So it seems my app would be able to send the device an ADB command, such as "adb shell am force-stop <PACKAGE>" to kill another app running on the same device.

Being able to kill the app this way seems to be a better way than these other methods because these other methods may not work on newer versions of android:

android.os.Process.killProcess(pid)
activityManager.forceStopPackage(packageName)

So, what is involved to use these java files in a B4A project?

this will open the process door for you. and may god have mercy on your soul.

Dim jo As JavaObject
jo.InitializeStatic("android.os.Process")
If Not(jo.IsInitialized) Then
    Log("not initialized")
Else
    Log(jo.RunMethod("myPid",Null))
End If

presumably, once you have the pid and the packagename, you can run your methods

But if I use that native method to kill the process, won't that require my app to have the "android.permission.KILL_BACKGROUND_PROCESSES" permission in the manifest?

If so, then that's what I am concerned about because newer versions of android might not allow that permission.

But, if I am able to use this alternate ADB command method, I think it will work without that permission.

I know nothing about this topic really, but I just wanted to add this thought: If it's possible to wield that much power by simply talk directly to ADB, we could assume with high certainty that there would be a lot more malware and other badly behaving apps out there. Which leads me to believe this probably won't work...

Also:

There is an app that uses this method and it's even available in the play store:
