Crashing on Android

[davidka95]

Hi,

Sometimes on Huawei p8 lite, I got this error:

java.lang.ClassCastException: 
  at com.facebook.react.bridge.ReadableNativeMap.getString (ReadableNativeMap.java:168)
  at com.azendoo.reactnativesnackbar.SnackbarModule.displaySnackbar (SnackbarModule.java:88)

  at com.facebook.react.bridge.queue.MessageQueueThreadImpl$3.run (MessageQueueThreadImpl.java:192)
  at java.lang.Thread.run (Thread.java:776)

I only use this method:

static showPositiveSnackbar(message) {
        Snackbar.show({
            backgroundColor: 'red',
            title: message,
            duration: Snackbar.LENGTH_LONG
        })
    }

Do you have any idea what the cause of the error is?

Environment

• Compile SDK Version: 27
• react 16.3.1
• react-native 0.55.4
• react-native-snackbar 0.4.7

Hmm, if you could determine reliable reproduction steps, that would help get to the bottom of the issue.

From the error it seems like react native is trying to read a string but it's getting a non-string. Is your message variable ever null?

Closing due to inactivity, but feel free to reply here if you have more info.

@davidka95 looks like you're passing not string to title property.
