Question

这是我在尝试使用FirebaseAuth和Firebase崩溃报告时遇到的异常。我正试着在我的申请onCreate

中匿名登录

public class MainApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();
        firebaseAuth.signInAnonymously().addOnCompleteListener(task -> {
            if (task.isSuccessful()) {
                Log.wtf("TAG", "Signed signInAnonymously successful ");
            }
        });
    }
}

我还想使用崩溃报告，因此我的gradle依赖项看起来像这样。

dependencies {
    // other dependencies
    // ...

    compile 'com.google.firebase:firebase-core:9.2.1'
    compile 'com.google.firebase:firebase-storage:9.2.1'
    compile 'com.google.firebase:firebase-auth:9.2.1'
    compile 'com.google.firebase:firebase-config:9.2.1'
    compile 'com.google.firebase:firebase-crash:9.2.1'
}

apply plugin: 'com.google.gms.google-services'

经过一段时间后，我会得到一个崩溃对话框和这个例外。它的另一个进程崩溃，所以应用程序本身仍将运行。

如果我删除了firebase-crash依赖项，那么就不会崩溃。

当您为应用中的每个流程创建自定义

function findAllMinimum(scores) {
  var minScore = _.min(_.values(scores));

  return _.filter(_.keys(scores), function (key) {
    return scores[key] === minScore;
  });
}

类时，在Firebase崩溃报告创建的单独流程上运行Firebase代码时，会导致

FirebaseApp with name [DEFAULT] doesn't exist。

您应该将代码从Application类移到其他地方。这可以在您的主要活动中（始终在您的主要流程中），也可以在您在Manifest中注册的Application onCreate() ContentProvider ContentProvider { {1}}在应用程序流程的生命周期中运行一次，就像onCreate()一样，但只能在一个进程中运行。

Firebase崩溃报告：名称为[DEFAULT]的FirebaseApp不存在
