I cannot help with windows. If any windows users see this please chime in. @luism3861 also try formatting your stack trace in triple backticks (`) so we can tell where the stack trace ends.

looks like an issue compiling java, ContactsManager.java:921: error: cannot find symbol. Please make sure you can use other react native libraries on android and doublecheck the android installation steps.

[luism3861]

i fixed this issue installing react-native-contacts:^4.0.2 :)

[morenoh149]

Others have reported that installing 4.0.2 works as well. What android version is your project targeting? 5.0.2 should be working on the latest android versions and latest react native versions.

[morenoh149]

What android version were you targeting? I think the new min android api version for react native apps is 28.

[yamov]

@morenoh149 I got a similar issue when upgraded from from v4.0.2 to v5.0.2.

We use RN 0.59.10 and these are the versions we are using in our build.gradle:

buildToolsVersion = "28.0.3"
minSdkVersion = 18
compileSdkVersion = 28
targetSdkVersion = 28
supportLibVersion = "28.0.0"

Tried to use v5.0.0 and still get the same error when I build the app. So apparently it's the Android X api 28 which is breaking it.

Justin case, here's the our error from the build log:

so that's it, for RN 60+ you have to use android x and rnc 5.x will work then. https://facebook.github.io/react-native/blog/2019/07/03/version-60#androidx-support mystery solved

[yamov]

So, do versions 5.0.0+ only work on RN 60+ with Android X support?
If so, I guess it can make sense to add a note to the Readme (and release notes, since it was a breaking change?). At the moment that is not apparent at all 🤔 .

[morenoh149]

I'll add a note. This is general react native details.

[yamov]

Thank you.
