我几天前启动了该应用程序。我在我的应用程序中使用 FireBase。但是前段时间我发生了一次未知的崩溃。

我检查日志时不知道错误发生在哪里。因为这似乎是 Google API 中的错误,而不是我的代码中的错误。

我找了一个与这个类似的问题,但我找不到。错误发生已经几天了,仍然没有解决。

我已经升级了与 Google API 相关的所有模块版本。我不知道有什么其他的方法。而且我正在使用应用程序混淆服务(不是proguard),我有点怀疑。

这是我的 gradle 文件依赖项

// 项目级gradle

dependencies {
        classpath 'com.android.tools.build:gradle:3.4.0'
        classpath 'com.google.gms:google-services:4.2.0'
        classpath 'io.fabric.tools:gradle:1.26.1'
        classpath 'com.google.firebase:firebase-plugins:1.1.5' 
    }

    testImplementation 'junit:junit:4.12'

}

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

这是firebase崩溃报告结果。

此外,以下情况。

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Context android.content.Context.getApplicationContext()' on a null object reference

许多用户已经感到不适。有谁知道问题是什么?
