React Native app crashes without any error log
React Native app crashing without any error log. No output on "react-native log-android" terminal, no red screen with error, Android emulator just crashes. Tried running with Expo, again crashes with no error
Happens when working with TextInput. I have some ideas how I can fix the code, but want to understand why is app crashing without error log and making debugging so much harder?
Answer
Run adb logcat
You can find your app name in your package.json, under the name field.
Also when looking for errors specifically dealing with react native, try running
adb logcat | grep 'redbox'
This way you don't have to scan the entire logfile.
Or try the method shown in this article. https://medium.com/@taufiq_ibrahim/using-adb-logcat-for-react-native-debugging-38256bda007c
