 To improve code coverage, start by identifying which lines are covered and which are not. To effectively increase coverage, trace the uncovered lines back to their calling functions, and ensure these are executed and tested in your test suites. The corresponding test files for the source code are usually located in the same package within the test directories. Add tests that cover all relevant behavioral scenarios for the uncovered lines to achieve comprehensive testing.

 Note: Some files in the app module may have multiple test files, located in the sharedTest and test packages, all testing a single source file. For example: [StateFragment.kt](https://github.com/oppia/oppia-android/blob/develop/app/src/main/java/org/oppia/android/app/player/state/StateFragment.kt) has 2 test files [StateFragmentTest.kt](https://github.com/oppia/oppia-android/blob/develop/app/src/sharedTest/java/org/oppia/android/app/player/state/StateFragmentTest.kt) under ``app/src/sharedTest`` and [StateFragmentLocalTest.kt](https://github.com/oppia/oppia-android/blob/develop/app/src/test/java/org/oppia/android/app/player/state/StateFragmentLocalTest.kt) under ``app/src/test``.
