Is this a bug report?

Yes

Have you read the Bugs section of the Contributing to React Native Guide?

Yes

Environment

1. react-native -v: 0.45 & 0.46.1
2. node -v: v6.9.1
3. npm -v: 3.10.8
4. yarn --version (if you use Yarn): 0.17.6

Then, specify:

1. Target Platform (e.g. iOS, Android): Android
2. Development Operating System (e.g. macOS Sierra, Windows 10): macOS Sierra

Steps to Reproduce

• Create a new react-native project using react-native init ExampleProject
• Add auth0 with yarn add react-native-auth0 and link it react-native link react-native-auth0
• And configure the Android project: https://github.com/auth0/react-native-auth0#configuration
• Add Redux, React Navigation and a few other JS libraries.

Expected Behavior

App should run without any kind of errors.

Actual Behavior

When I want to run the app with react-native run-android after writing some code and adding logic without touching the native Java code and with a successful build, I get this error:

BUILD SUCCESSFUL

Total time: 10.072 secs
Running adb -s 0259749fb8c21037 reverse tcp:8081 tcp:8081
Starting the app on 0259749fb8c21037 (adb -s 0259749fb8c21037 shell am start -n com.woodyapplication/com.woodyapplication.MainActivity)...
Starting: Intent { cmp=com.woodyapplication/.MainActivity }
Error type 3
Error: Activity class {com.woodyapplication/com.woodyapplication.MainActivity} does not exist.

I managed to fix this with the following hacks:

• creating a new project and copy the JS code over (which is not a solution)
• replace the package name com.woodyapplication with com.woody.application (or something else). This fixes it for a few runs but then the error message appears again.

I've tested this with RN 0.45 and RN 0.46.1 the bug appears on both versions
