We're building an open-source tool to help you determine whether or not a particular application is malicious. This tool uses a technique called "check-call", where we look at the content of a call and the app's status. If the content is malicious, we'll fail the call.

This tool was built using a public API provided by the Android team, so it can be used by any app that provides such an API.

In order to use this tool, you need to install it on your Android device. To do this, you need to install this application and then you need to install the application you want to check. You need to make sure that both of these applications are from the Android team.
