Last week I wrote a script that would control which permissions an app had access to. It did this by unpacking the app with APKTool, editing the AndroidManifest.XML file to remove the unwanted permissions, then repackaging the whole thing. This works because if the app doesn't request a permission in its manifest, the system will not give it that permission, effectively limiting the app. There are a few cases in which the app cannot run without a certain permission, but I was not able to determine when this would occur or prevent it.
I also had some fun learning about how to incorporate command line arguments into a script, and I made this script accept the name of the app to edit in the terminal so that users wouldn't have to edit the app's name for the script to recognize it.
Here is the script, by the way:
