 ## Troubleshooting
 
-- If you encounter issues with the `verifyResourceRelease` task, try enabling `enableMatchDebugVariant`.
-- Ensure that the `bundletool` JAR file is correctly referenced in your configuration.
+### Resource Verification Failures
+If you encounter issues with the `verifyResourceRelease` task, try these solutions:
+- Check that your resource files are properly formatted and located
+- Verify that resource names follow Android naming conventions
+- Enable the `enableMatchDebugVariant` flag in your configuration
+
+### Dagger NoSuchMethodError
+If you encounter this exception:
+```java
+NoSuchMethodError: 'java.lang.Object dagger.internal.Preconditions.checkNotNullFromProvides'
+```
+This error typically occurs due to a version conflict between the Android build tools and the App-Sizer plugin's Dagger dependencies. To resolve:
+
+1. Ensure the App-Sizer plugin is added to the classpath in the root build.gradle before applying it to your app module
+2. If step 1 doesn't resolve the issue, you might have to resolve the Dagger version conflict by adding this to your classpath
+```
+classpath "com.google.dagger:dagger:2.47"
+```
