Examer
Examer is an Android app that is used to take tests that evaluate a person's ability to listen to, and understand conversations in English.

Note
Although the app works, the development of this project has been permanently stopped. There is no intention of continuing the development of this project. The features implemented will work, but bugs are bound to exist. The app doesn't handle most of the exceptions, especially those related to network. FCM (Firebase Cloud Messaging) is used in the app, but, the token is just logged and not stored anywhere.
