Compile error - promise

[ArthurKnoep]

1. What version of RN and react-native-fcm are you running? RN: 0.56.0 / React-Native-FCM: 16.2.1
2. What device are you using? (e.g iOS9 emulator, Android 6 device)? Android 8.0 device
3. Is your app running in foreground, background or not running? Not compiling

When I create an react native app with react-native init and add react-native-fcm with npm, I cannot compile the projet with react-native run-android

Logs:

:react-native-fcm:compileReleaseJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.).

This change came from version 16.2.1....

You can fix that by changing your dependency in your package.json : "react-native-fcm" : "16.2.0" (important : remove the ^ to force this exact version)

@wynch Thank you that worked.

[ArthurKnoep]

@wynch Thanks a lot, it works now

The error comes from this file

https://github.com/evollu/react-native-fcm/blob/master/android/src/main/java/com/evollu/react/fcm/FIRMessagingModule.java

the Method public void unsubscribeFromTopic(String topic)(line 225) signature should be public void unsubscribeFromTopic(String topic, Promise promise)

[ArthurKnoep]

Is this normal ?

fixed in 16.2.2
