Question

我写的这个问题似乎重复了一次，因为没有一种解决方案对我有用。

我的移动设备描述：

华为LYO-L02

EMUI 3.1

Android 5.1

我的问题是，我在我的应用中订阅了Google Firebase服务。当我尝试打开应用程序时，它崩溃并显示以下信息。

我已经确定清单文件具有扩展应用程序类的应用程序，并且

@Override 
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}

已经完成。

我的Gradel文件说明：

    defaultConfig {
        applicationId "com.myappid"
        minSdkVersion 21 //android 5 minimum
        targetSdkVersion 26
        // Enabling multidex support.
        multiDexEnabled true
}

这些链接都没有帮助我。 https://github.com/firebase/quickstart-android/issues/105 Didn't find class "com.google.firebase.provider.FirebaseInitProvider"? https://developer.android.com/studio/build/multidex.html

如果您需要更多说明，我们将非常乐意提供。谢谢

Answer 1

构建依赖项存在许多问题。

您应该不使用com.google.android.gms:play-services:X.X.X。 The documentation for using Play Services解释：

请勿使用合并的播放服务目标。它带来了数十种库，使您的应用程序膨胀。而是仅指定您的应用使用的特定Google Play服务API

有关特定API的列表，请参见上面链接的文档。仅使用您需要的特定对象。解决此问题后，您可能不需要使用MultiDex。

您正在使用许多库的非常旧的版本。查看每个文档，并尝试使用与您的版本兼容的最新可用版本。 Firebase SDK的最新版本为listed here。 Table 1 of the Setup Guide中列出了Play Services API的最新版本。

它也可能有助于升级到Google Services Gradle Plugin的较新版本。最新版本是4.2.0。

订阅的Firebase服务启动后，应用程序崩溃
