I'm new to react native, and I'm trying to install the react native Facebook SDK so that I can do Facebook login with my app.

I followed the steps listed here: https://tylermcginnis.com/installing-the-facebook-sdk-into-a-react-native-android-and-ios-app/

The problem is that when I run react-native run-android, the app crashes immediately. How do I debug this crash? I don't know where to look for crash logs. Running react-native log-android doesn't show me anything useful.

Edit:

I know that this a Java issue rather than a JS issue. How can I find Java crash logs?

  • What specifically happens when you run react-native run-android? Do you receive no response, like does it just return the terminal prompt? Commented Mar 27, 2017 at 0:55
  • The react-native run-android command succeeds Commented Mar 27, 2017 at 0:57
  • Then do you have a virtual machine or actual Android phone set up to receive the message? Commented Mar 27, 2017 at 0:59

To see Java logs, open AndroidStudio, and click on AndroidMonitor at the bottom of the screen.

I was able to see the crash stack trace. My problem is that I need to set a valid facebook app id in AndroidManifest.

In AndroidMonitor, there's a log which says "Please configure Android SDK", how do we configure it?
This tool was removed in Android Studio 3.0.

You should build the app using Android Studio, then select the 'debug' tab at the bottom to see the console output
