 3. **java.lang.ClassNotFoundException: com.android.tools.r8.compatdx.CompatDx**
 
    If, when building the app binary, you encounter a failure that indicates that the CompatDx file cannot be found, this is likely due to you using a newer version of the Android build tools. You can manually downgrade to an older version of build-tools (particularly 29.0.2). Unfortunately, this can't be done through Android Studio but it can be done over a terminal. Follow the instructions listed [here](https://github.com/oppia/oppia-android/issues/3024#issuecomment-884513455) to downgrade your build tools & then try to build the app again.

+      ```
+Bazel requires Xcode commandline tools to build on M1, and the Xcode license also needs to be accepted.
+
+   **Follow these steps to solve this error:**
+
+- Install the commandline tools: `xcode-select --install`
+
+- Accept the Xcode licence: `sudo xcodebuild -licence`
+
+- Reset the xcode select path: `sudo xcode-select -r `
+
+ - Set the xcode select path to use CommandLineTools: `sudo xcode-select -s /Library/Developer/CommandLineTools`
+
+- Confirm that the path was correctly set. The expected output is: `/Library/Developer/CommandLineTools`
+
+      xcode-select -p
+
+After successfully running the above commands, build the app using Bazel by running the following command:
+
+      ```
+      bazel clean --expunge
+      bazel build //:oppia --noexperimental_check_desugar_deps
+      ```
+The `--noexperimental_check_desugar_deps` flag is explained in the [bazel blog](https://blog.bazel.build/2018/12/19/bazel-0.21.html#android).
