This error message is typically encountered when the class specified in the manifest file is not present in the project or any of the imported libraries. Here are some possible solutions:
1. Check that the package name in the manifest file (`com.example.choosepictest`) matches the package name of your MainActivity class.
2. Make sure that your MainActivity class is located in the correct directory within your project's file structure. It should be located in `app/src/main/java/com/example/choosepictest/MainActivity.java`.
3. Check your dependencies in the `build.gradle` file to ensure that all necessary libraries are included and up to date.
4. If you recently renamed your MainActivity class, make sure that you updated all references to it in the manifest file and in any other code that uses it.
5. Check that your MainActivity class is not marked as private or protected, as this can prevent it from being accessed by other parts of your project.
If none of these solutions work, try cleaning and rebuilding your project to see if that resolves the issue.
