Uninstall an app programmatically

Question

I want to develop an open source app for uninstalling applications. How can I do this?

And how can I uninstall an app that is in /system/app/ after I gain root access?

Thanks

Answer 1

You can execute adb commands from within your app if you have root access like this

Process process = Runtime.getRuntime().exec("your command");
BufferedReader bufferedReader = new BufferedReader(
                                    new InputStreamReader(process.getInputStream()));

use try catch as well for this code

Answer 2

After a little searching on the android developer website I found this package installer which facilitates the installation and removal (amongst other things) of apps.

public class PackageInstaller
void uninstall (String packageName, 
            IntentSender statusReceiver)

Uninstall the given package, removing it completely from the device.

I hope this covers your requirements.
