Could not find com.android.support:support-v4:23.2.1

Question

When using react-native 0.28 and above (0.29, 0.30-rc), I get the following error when executing react-native run-android in a fresh react-native init app project.

Could not find com.android.support:support-v4:23.2.1.

I installed the newest android studio and even installed the obsolete library manually.

What am I doing wrong? Thanks!

Answer 1

To complete Tonithy's answer - the .jar may not be enough, you need to copy two whole directories, otherwise gradle will complain for the missing .aar. In this case, I think that those were installed by Android Studio: {USER}/Library/Android/sdk/extras/android/m2repository/com/android/support/support-v4/23.2.1/

And don't forget the dependency: {USER}/Library/Android/sdk/extras/android/m2repository/com/android/support/support-annotations/23.2.1/

I had exactly the same problem while upgrading to react-native 0.30, that solved the issue.

Google seems to have stopped including a version of each support library without sources/javadoc/etc and React is looking for this specific file. Assuming you manually installed the obsolete version, it will be in {YOUR_ANDROID_LOCATION}/extras/android/support/v4/android-support-v4.jar Your best bet is to manually copy it in:

cp {YOUR_ANDROID_LOCATION}/extras/android/support/v4/android-support-v4.jar {YOUR_ANDROID_LOCATION}/extras/android/m2repository/com/android/support/support-v4/23.2.1/support-v4-23.2.1.jar

This a React Native (version and probably OSX specific bug), it will probably be fixed soon. For posterity, your full error was something like this, looking for support in all the wrong places:
