Android ClassNotFoundException: Resolving "Didn't Find Class" Errors

When encountering the "Didn't find class" error in Android development, a ClassNotFoundException is thrown. This can occur during instantiation of an activity, where the specified class cannot be located in the DexPathList, leading to the failure of the app to launch.

To address this issue, it is crucial to ensure that the class in question is properly mentioned in the manifest file, as indicated in the provided code snippet. However, if the error persists despite this, it is likely due to a version conflict in the Android support library between the main project and any included library projects.

Resolving Version Conflict

To resolve the version conflict, it is necessary to use the same version of the Android support library in both the main project and the included library projects. By ensuring consistency in support library versions, potential conflicts and subsequent ClassNotFoundExceptions can be avoided.

Additionally, cleaning the build after making these changes is highly recommended to refresh the project's build environment and minimize any potential issues. This can be achieved through the "Clean" option in the "Build" menu of your Android Studio IDE.

Following these steps will increase the likelihood of successfully resolving the ClassNotFoundException and allowing your app to launch correctly. Remember to be vigilant in managing version consistency and perform clean builds regularly to maintain a stable and error-free development environment.
