 Create an Android project based on an empty activity, and then add dependency. Since Zap is distributed through JitPack, you need to first add the JitPack repository to the `settings.gradle` file.

 Next, add the dependency to the `build.gradle` file. Replace `$VERSION` with your desired version. For example, if you want to use version v0.1.0, input `0.1.0`.

 In this state, when you build and run the application, the values measured based on the x, y, z axes will be logged every time the device is tilted. Now, let's send the values to the server using Zap. Since Zap communicates through UDP socket, you need to add `INTERNET` permission to the `AndroidManifest.xml` file first.
