Firebase RemoteConfig crashes app with signal 11 (SIGSEGV)

Question

I have a Unity app and I use a bunch of plugins provided by Google: Play Games Services, AdMob, Firebase Analytics. They all work perfectly fine. Now I want to add Firebase RemoteConfig. But I can't because my app is constantly crashing (on android device) when I try to do anything with RemoteConfig. I trying googling but didn't find anything similar. My code looks something like this:

public class RemoteConfigManager
{
    void Start()
    {
        Debug.Log("Start");
        var dependencyStatus = Firebase.FirebaseApp.CheckDependencies();
        if (dependencyStatus != Firebase.DependencyStatus.Available)
        {
            Debug.Log("Trying to fix dependencies");
            Firebase.FirebaseApp.FixDependenciesAsync().ContinueWith(task =>
            {
                dependencyStatus = Firebase.FirebaseApp.CheckDependencies();
                if (dependencyStatus == Firebase.DependencyStatus.Available)
                {
                    Debug.Log("Fixed dependencies");
                    SetDefaults();
                }
                else
                {
                    Debug.LogError("Could not resolve all Firebase dependencies: " + dependencyStatus);
                }
            });
        }
        else
        {
            Debug.Log("Dependencies ok");
            SetDefaults();
        }
    }

    void SetDefaults()
    {
        Debug.Log("Set defaults");
        var configuration = ConfigurationManager.Instance.Configuration;
        var defaults = new Dictionary<string, object>();
        defaults.Add("some_key", 1);
        FirebaseRemoteConfig.SetDefaults(defaults);
    }
}

SIGSEGV happens when FirebaseRemoteConfig.SetDefaults() is called. Stack trace looks like this:

I tried different variants but always get this SIGSEGV. Any ideas?

Answer 1

I ran into the same problem. It seems when installing the RemoteConfig package it doesn't install all the required Android libraries. Using the Play Services Resolver tool pulled in a needed remote config library and then it worked ok.
