在 react-native Android 发布版本上查看控制台日志

Question

I'm currently facing an issue which only exists in production/release build for Android. Is it possible to run debugger or view logs for production/release builds?

Answer 1

Use console.log , console.warn , etc.

You can try simply run the following to see logs in the console:

react-native log-ios
react-native log-android

Answer 2

Maybe this or this could help.

Try something with

if (__DEV__) {
    //log in dev build
} else {
   //log in product build
}

Answer 3

Try the following:

Run the logger for android using the following:

npx react-native log-android

Then run your app in release mode:

npx react-native run-android --variant=release

All of your console.log() and console.warn() should be displayed.
