Didn't find class com.android.mail.providers.conversation

A common issue!

The error message "didn't find class com.android.mail.providers.conversation" typically occurs when the Android app is trying to access a class or package that is not available or not properly installed.

Here are a few possible solutions to resolve this issue:

  1. Check if the app is properly installed: Make sure that the app is installed correctly and that the installation was successful. Try uninstalling and reinstalling the app to see if that resolves the issue.
  2. Check for updates: Ensure that the app is up-to-date. Sometimes, updates can resolve issues like this.
  3. Clear app data and cache: Clearing the app's data and cache can sometimes resolve issues like this. Go to Settings > Apps > [App Name] > Storage > Clear data and Clear cache.
  4. Check for conflicts with other apps: If you have multiple apps installed that provide similar functionality, try uninstalling one or more of them to see if that resolves the issue.
  5. Check the app's permissions: Ensure that the app has the necessary permissions to access the required classes or packages. Go to Settings > Apps > [App Name] > Permissions to check the app's permissions.
  6. Try a different device or emulator: If you're testing the app on an emulator or a different device, try testing it on a different device or emulator to see if the issue is device-specific.
  7. Check the app's build configuration: If you're building the app yourself, check the build configuration to ensure that the required classes or packages are included in the build.
