Flipper is a tool created by Facebook to support the development and debugging of Android apps (iOS and React Native, too).
It is a toolbox full of mini-tools, called plugins, that do all kinds of wonderful things. Some of which exist in some form in Android Studio, but many of which do not.
It can also be very useful for your QA team. They may not use Android Studio, so even an external logcat would still be extremely helpful for them.
Here are some of the out-of-the-box plugins available for Flipper
Network call logs
Network call mocking
Crash reporting
Image inspector
Database inspector
Shared Preferences inspector
Logcat
Flipper is written with the Electron framework and runs on the desktop/laptop while connected to physical devices or emulators/simulators. It is completely open source so its additional super-power is its ability to support custom plugins that can provide app specific features like:
Analytics logging (I’m looking at you Adobe)
Managing User logins for testing
Feature toggles
Adb commands
And a plethora (look it up – it’s a good thing!) of 3rd party plugins
Start using it now. You’ll wonder how you ever developed without it.
