[Android] assembleRelease fails: android.support.annotation does not exist

💻 My environment

• react-native-bootsplash version: 2.2.4
• react-native version: 0.62.2
• Platform: android
• OS version:
• Device: any
• Simulator: no
• Android Studio version: 3.5
• Android buildToolsVersion: 5.4.1
• Xcode version: N/A

🕵️‍♂️ Reproducing the issue

I followed the installation instructions step by step. iOS works perfectly. Android works in the simulator perfectly (by running react-native run-android), but fails on build (with both assembleDebug and assembleRelease) with the following error:

@zoontek alright man, so we had jetify -r for some reason in our project…Don’t know how that had not given us issues before. That, plus doing react-native clean-project-auto worked like a charm. Thanks for the insights.

[zoontek]

For some reason, your assembleDebug seems to run a reverse jetify (jetify -r).

If you check the library code, you will see that the imports are differents (they correctly target AndroidX):

• RNBootSplash.java#L14
• RNBootSplashActivity.java#L7

Etc.

That’s not what is reported.

I would advice to clean a bit the project, stale cache config being probably still around.

Run react-native clean-project-auto + ./android/gradlew clean + delete all *.iml files.
