Android crashes NullPointerException

#1

Hi all!

I made an app which is on the App Store and Google Play and I’m getting crashes on Android from Expo.

// package.json
    "expo": "^20.0.0",
    "react": "16.0.0-alpha.12",
    "react-native": "https://github.com/expo/react-native/archive/sdk-20.0.0.tar.gz",
    "exp": "44.0.0"

// app.json
    "sdkVersion": "20.0.0",

I’ll make 2 kinds of Topic for the 2 kinds of Java exception I’m getting, but here’s the first one: NullPointerException


java.lang.NullPointerException: 
  at host.exp.exponent.experience.h.run (ExperienceActivity.java:347)

and

java.lang.NullPointerException:

Those are the 2 kinds of NullPointerException I’m getting from my app. The second one seems weird, because my app doesn’t use any Speech feature…

Any idea of the cause and/or potential fix?

Thanks :blush:

@jesse do these look familiar to you?
