The error message "Failed to instantiate test runner class androidx.test.internal.runner.junit4.AndroidJUnit4ClassRunner" means that the Android test runner class, which is responsible for running JUnit 4 tests on an Android device or emulator, could not be instantiated. This could happen due to a number of reasons, such as a configuration issue, a missing dependency, or an incompatibility with the Android version or API level. To fix this error, you should check your project setup and dependencies, update your Android tools and libraries, and make sure that your test code follows the JUnit 4 syntax and conventions.
