When you want to use **Crashlytics NDK**, you need call `Fabric.with(this, new Crashlytics(),new CrashlyticsNdk());` But Firebase Crashlytics calls 
`Fabric.with(context, new Kit[]{new Crashlytics()});` on startup.
As the result you cannot use Crashlytics NDK.

How can I avoid this problem?

```
public class CrashlyticsInitProvider extends ContentProvider {
private static final String TAG = "CrashlyticsInitProvider";

public CrashlyticsInitProvider() {
}

public boolean onCreate() {
    Context context = this.getContext();
    FirebaseInfo firebaseInfo = new FirebaseInfo();
    CrashlyticsInitProvider.EnabledCheckStrategy enabledCheckStrategy = new ManifestEnabledCheckStrategy();
    if (this.shouldInitializeFabric(context, firebaseInfo, enabledCheckStrategy)) {
        try {
            Fabric.with(context, new Kit[]{new Crashlytics()}); // !here
            Fabric.getLogger().i("CrashlyticsInitProvider", "CrashlyticsInitProvider initialization successful");
        } catch (IllegalStateException var5) {
            Fabric.getLogger().i("CrashlyticsInitProvider", "CrashlyticsInitProvider initialization unsuccessful");
            return false;
        }
    }

    return true;
}

```
