react-native-fbsdk-next is not working just on android

If react-native-fbsdk-next is not working only on Android, there could be several reasons for this issue. Let's go through some common troubleshooting steps to identify and resolve the problem:

1. Check Dependencies and Installation: Make sure you have correctly installed the required dependencies for react-native-fbsdk-next and have linked the library to your Android project. Ensure that you have followed the installation steps provided in the library's documentation.

2. Check Android Manifest: Verify that the necessary configurations are present in the AndroidManifest.xml file. react-native-fbsdk-next requires Facebook App ID and permissions to be properly configured. Ensure that the following lines are present in your AndroidManifest.xml:

   xmlCopy code
   <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>
   <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
   

3. Check Proguard Configuration (if applicable): If you are using Proguard in your Android project, ensure that you have configured the necessary rules to keep the Facebook SDK classes and prevent them from being obfuscated.

4. Verify Facebook SDK App Settings: Check the settings of your Facebook App in the Facebook Developer Dashboard. Ensure that the package name and hash key are correctly configured for your Android app. The package name and hash key must match the ones from your Android project.

5. Check for Error Messages: Inspect the logs and error messages in the Android Studio Logcat or by running adb logcat in the terminal. Look for any relevant error messages related to the Facebook SDK or react-native-fbsdk-next.

6. Test on a Real Device: Test the application on a real Android device instead of an emulator. Emulators sometimes have limitations or different configurations that can affect the behavior of third-party libraries.

7. Update React Native and Dependencies: Make sure you are using the latest version of react-native and react-native-fbsdk-next. Sometimes, updating to the latest versions can resolve compatibility issues.

8. Check Gradle and SDK Versions: Verify that your Android Gradle plugin and Android SDK versions are compatible with the Facebook SDK and react-native-fbsdk-next. Ensure that you have installed the necessary SDK versions using Android SDK Manager.

9. Clear Build Cache: Try clearing the Android build cache to ensure that any cached files or configurations are refreshed.

10. Rebuild the Project: Perform a clean build of your Android project to ensure that all changes are properly applied.

By going through these steps, you should be able to identify the cause of the issue and resolve the problem with react-native-fbsdk-next on Android. If the problem persists, consider checking for any updates or known issues in the library's GitHub repository or seeking help from the library's community.
