Cannot find symbol cannot find symbol: method toArrayList()

[fdobre]

React-native 0.50.4, react-native-admob 2.0.0-beta.3,

When trying to build with react-native run-android:

I get 5 errors likes this (for each file in /rnadmob):
/node_modules/react-native-admob/android/src/main/java/com/sbugert/rnadmob/RNAdMobInterstitialAdModule.java:117: error: cannot find symbol ArrayList<Object> list = nativeArray.toArrayList(); ^ symbol: method toArrayList() location: variable nativeArray of type ReadableNativeArray

This happened after an update from 1.3.2 to react-native-admob 2.0.0-beta.3 and an update of react-native from 0.45 to 0.50.
Am I doing something wrong?

I ran react-native link, cleaned cache etc.

Please advise.

Any advice or suggestion will be greatly appreciated.

IOS building works ok.

@fdobre - I encountered this same issue and just rebuilt the node_modules and android folders.

$ rm -rf node_modules
$ rm -rf android
$ yarn
$ react-native link
$ yarn android

Rebuilding all of that seemed to fix everything.

@nbucciarelli removing node_modules and re-linking didn't work.
Removing the whole android folder is not an option for me.

Downgrading to react-native-admob@1.3.2 seems to work.

Somehow in v2.0.0 the toArrayList from the facebook package is not detected... (maybe this was added after rn 0.45). I am still investigating the issue and trying workarounds...

I tried removing node_modules and re-linking but it didn't work. When downgrading to 1.3.2 the error disappears.

I also tried to upgrade RN to 0.51.0 and the issue persists in this version too.

@fdobre I think your android project still have the old linking.
You should open your project in android studio and check your main activity class
My answer to you on stackoverflow

I found it was a gradle issue, not a react-native-admob problem.
I fixed it with changing the react native url from gradle file.
