Flutterfire: 🐛 [firebase_remote_config: 0.4.1] Plugin using removed method, causing app to crash

Created on 5 Nov 2020  ·  12Comments  ·  Source: FirebaseExtended/flutterfire

Bug report

Using the newest release from the Firebase Android SDK, the app crashes immediately when RemoteConfig.instance gets called. This error gets displayed before the crash:

E/flutter (18539): [ERROR:flutter/shell/platform/android/platform_view_android_jni_impl.cc(43)] java.lang.NoSuchMethodError: No virtual method isDeveloperModeEnabled()Z in class Lcom/google/firebase/remoteconfig/FirebaseRemoteConfigSettings; or its super classes (declaration of 'com.google.firebase.remoteconfig.FirebaseRemoteConfigSettings' appears in /data/app/my.app-ItOxdJo5ljyanMFjofxlDg==/base.apk)

The cause is that isDeveloperModeEnabled got removed from FirebaseRemoteConfigSettings on this commit. The method was deprecated a while ago, yet it is still used here.

Steps to reproduce

Steps to reproduce the behavior:

  1. Create a new Flutter app.
  2. Install and configure the firebase_remote_config package using the latest Firebase Android SDK (com.google.firebase:firebase-config:20.0.0 or com.google.firebase:firebase-bom:26.0.0)
  3. Put final RemoteConfig remoteConfig = await RemoteConfig.instance; somewhere in the code.
  4. The app now crashes when that code is reached.

Expected behavior

The app should not crash.

Expecting fix soon!

A workaround for a temporary fix, Go to your pub cache dir, find MethodCallHandler.java and replace this line:

properties.put("inDebugMode", firebaseRemoteConfigInfo.getConfigSettings().isDeveloperModeEnabled());
with
properties.put("inDebugMode", false);

Also, change the following 

FirebaseRemoteConfigSettings settings = new FirebaseRemoteConfigSettings.Builder().setDeveloperModeEnabled(debugMode).build();
firebaseRemoteConfig.setConfigSettings(settings);

with

FirebaseRemoteConfigSettings settings = new FirebaseRemoteConfigSettings.Builder().build();
firebaseRemoteConfig.setConfigSettingsAsync(settings);

I couldn't do this as the file doesn't have any line as described. Any ideas?

In my case it worked after commenting Firebase-bom dependency [implementation platform('com.google.firebase:firebase-bom:26.1.0')] and given versions manually for other firebase dependencies.

🥇 🥇 🥇 🥇 🥇

Okey not only changing this
properties.put("inDebugMode", firebaseRemoteConfigInfo.getConfigSettings().isDeveloperModeEnabled());
to
properties.put("inDebugMode", false);

& changing this

FirebaseRemoteConfigSettings settings = new FirebaseRemoteConfigSettings.Builder().setDeveloperModeEnabled(debugMode).build();
firebaseRemoteConfig.setConfigSettings(settings);
to
FirebaseRemoteConfigSettings settings = new FirebaseRemoteConfigSettings.Builder().build();
firebaseRemoteConfig.setConfigSettingsAsync(settings);

You need also to change this

FirebaseRemoteConfig.getInstance().setDefaults(defaults);
to
FirebaseRemoteConfig.getInstance().setDefaultsAsync(defaults);

Still its an annoying issue and should be solved asap

1- Open this dir /SDK/flutter/.pub-cache/hosted/pub.dartlang.org/firebase_remote_config-0.4.2/android/src/main/java/io/flutter/plugins/firebase/firebaseremoteconfig
2- you will find this file MethodCallHandlerImpl.java

it will contains the same source
