Hey guys i have an app on playstore and it uses firebase as well. A lot of app crashed nowadays on Android 5.1 and 5.0 version.
The name of the error is java.lang.NullPointerException
com.google.appinventor.components.runtime.Network$1.onReceive
Can anyone tell me with what this error is related to ?
It’s the Network component. But I’m not sure why the error is happening. We’ll take a look to see if we can find out why it’s happening.
