React Native Flipper Debugging Issue : "NO APPLICATION SELECTED"

enter image description here

I have managed to connect a device ( I see logs and see the tree of React Native elements), but now I have an issue with connecting the app - "NO APPLICATION SELECTED" is what I see. Any ideas to fix it?

Solution

  • Ran into the same problem on both iOS and Android with Flipper 0.135.0. Managed to make both work by following the steps below.

    iOS

    This answer solved the issue for me.

    tl;dr

    brew update && brew upgrade idb-companion

    Also make sure you are installing the correct Cocoapod of Flipper by specifying the exact version in your Podfile with (for version 0.135.0)

    use_flipper!({ 'Flipper'=> '0.135.0' })

    Android

    Ensure that ReactNativeFlipper.java is in the correct folder, as in this example project.

    With for example the applicationId com.domain.appName, the correct path is

    android/app/src/debug/java/com/domain/appName/ReactNativeFlipper.java

    In my project this Java file was in the incorrect folder, which resulted in the Logcat error

    java.lang.ClassNotFoundException: com.domain.appName.ReactNativeFlipper
