React-native-firebase: RNFirebase V3 dont work in Android 4.4.2 KitKat - bug

[DaniRZ]

I followed all the steps indicates in the page and use the last version of this lib, when I run in my cellphone a Android 4.4.2 the app crash without indicating any error but when i run the same app in a Android 7.1 the app works perfectly and I could get and post data.

So I decide change the version for react-native-firebase 2.1.4, when I did the respective changes according to the version, the app works perfectly again. I thinks that the libs have errors with android < v7

I don't have the code because I change the version, sorry.

React - Native: v0.49
RNFirebase: 3.0 - error
RNFirebase: 2.1.4 - works!

Logs? Errors?

[DaniRZ]

no logs, no errors, build usually but crash when I launch the app in Android 4.4.2 and when i launch in android 7.1 works perfectly.

Run adb logcat - there will be an Exception somewhere in the logs explaining why it is crashing

No error for me. I'm using messaging and analytics modules.
Android: 4.4.2 (emulator)
React Native: 0.48.4
React native firebase: 3.0.3

Logs will help a lot. Which firebase sdk modules are you using ?

Yep, I have same problem.
And only on Android 4.4.2
On android 5, 7 works perfectly but a dialog with message "this app won't run without google play services which are missing from your phone" after i update Google Play service on drive then good.
This is log:

Thanks for the stack trace @agumack

A quick google search indicates that this might be a MultiDex error and is Firebase related rather than RNFirebase.

Please check the following Stack Overflow posts:

I'm going to close this as it's not really a RNFirebase issue and these articles should help you resolve the issue.
