Firebase 和 Facebook 的 ExceptionInInitializerError

Question

我最近将 firebase 升级到最新版本，现在使用我们的服务器生成的自定义令牌进行身份验证。我还在对我的 firebase 实例进行自定义初始化，如此处 https://firebase.googleblog.com/2017/03/take-control-of-your-firebase-init-on.html 所述。初始化是在我的应用程序 onCreate 方法的第 3 行完成的（在调用 super 并设置静态实例变量之后），所以它尽早完成。

我得到以下异常，但它不能始终如一地重现，所以它似乎是 firebase 和 facebook sdks 之间的某种竞争条件。

更新删除 firebase 性能插件似乎可以解决问题；但是，我想要插件提供的自动跟踪，所以我想找到一个允许我同时使用 firebase 和 facebook

的解决方案

Answer 1

Facebook 表示他们的 android sdk 目前与 firebase 性能插件不兼容。

Answer 2

问题的原因似乎是 Facebook SDK 在 Firebase Performance 初始化之前尝试进行网络请求。我找到了一个强制 Firebase 在 facebook 之前初始化的解决方案。

在您的 Android 清单中删除 Firebase 和 Facebook 的 "init providers"。这些在每个 SDK 中用于自动初始化每个库。 2.You 然后可以从 Application onCreate 方法手动初始化每个库，在 Facebook 之前调用 Firebase。

在你的AndroidManifest.xml文件中：

    <!--Init Firebase manually in Application class-->
    <provider
        android:name="com.google.firebase.provider.FirebaseInitProvider"
        android:authorities="${applicationId}.firebaseinitprovider"
        tools:node="remove"
        />

    <!--Init Facebook manually in Application class-->
    <provider
        android:name="com.facebook.internal.FacebookInitProvider"
        android:authorities="${applicationId}.FacebookInitProvider"
        tools:node="remove"/>

在你的申请中class

@Override
public void onCreate() {
    super.onCreate();
    FirebaseApp.initializeApp(this);
    FacebookSdk.sdkInitialize(this);
}

我不认为这是一个很好的解决方案，但它现在可以完成工作，直到 Facebook 或 Firebase 更新他们的库以在应用程序启动期间停止此冲突。
