error: cannot find symbol class ReactApplication
I can't run my react-native project because of this Java Compiler error. Below is an image of error logs attached for reference:
error: cannot find symbol class ReactNativeHost
error: cannot find symbol class ReactApplication
It seems like Android Studio doesn't recognize:
import com.facebook.react.ReactApplication;
import com.facebook.react.ReactNativeHost;

No, @Lucefer . The thing is the project syncs correctly, but when I run it on the emulator, it gives that error.

Check your package.json. If it looks something like:
"react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz"
(Currently this is the case after ejecting from Expo: npm run eject)
Then reinstall react-native:
npm uninstall react-native
npm install react-native
You package.json looks like below now:
"dependencies": {
"react": "16.6.3",
"react-native": "0.58.1"
},
Now try rebuilding your project in Android Studio, the error should go away.
