Information:
Blocker is a component controller for Android applications. Currently, it supports using PackageManager and Intent Firewall to control the state of components, and it can be extended in the future. You could switch between these controllers seamlessly. For the application rules, you could export & import them. It is compatible with the backup files generated by MyAndroidTools, and you could convert it to Intent Firewall rules without any effort.
Disclaimer: I do not own this application or tool. I'm just here to share it, but you're free to support the developer. The tool/application's working capability and other issues depend on keeping the project alive by the author. Use it at your own risk.
