Android 尝试获取集合时发生firestore崩溃运行时异常

我正在尝试从firestore获取集合。我收到以下错误

首先，尝试清除设备上应用程序管理器中的数据，然后再次运行应用程序。如果不以这种方式工作，请尝试将以下代码行添加到progauard规则中：

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

尝试将

-keep class io.grpc.*{*}

添加到proguard配置中。它应该会起作用。就我而言，它起了作用。如果没有，请添加你的

build.gradle

文件。我重新安装了应用程序，它现在可以工作了。似乎只有在我尝试调试应用程序时才会发生。我的回答对你有帮助吗？它仍然不工作，但只在调试模式下发生

db.collection("mycollection").get().addOnCompleteListener

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}
