我有一个应用程序，我在其中集成了 Crashlystics 库，它可以捕获应用程序中的致命问题并向开发人员报告。
方法如下:
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
Fabric.with(this, new Crashlytics());
}
}
这里是依赖:
apply plugin: 'io.fabric'
compile('com.crashlytics.sdk.android:crashlytics:2.6.6@aar') {
transitive = true;
}
compile 'com.google.android.gms:play-services:10.2.0'
今天，我收到一份报告显示此错误:致命异常:java.lang.NullPointerException
尝试在 类。此错误发生在运行 android marshmallow 的 LGE 设备上。com.google.android.gms.internal.zzbsp 中对空对象引用 调用虚方法“java.lang.String java.lang.String.toLowerCase(java.util.Locale)” .zzabx(未知来源)
来自 Fabric.io 的 crashlytics 的完整堆栈跟踪:

这是什么错误，我为什么会收到它？
最佳答案
这是 GMS 库中的错误。 在 Google 的一些虚拟测试设备上出现此错误(始终是 Nexus 5x API 23 en-US ...)
有关更多信息，请参阅此问题:NullPointer on toLowerCase but I don't use that method anywhere
关于android - 在 'java.lang.String.toLowerCase()' 类的 crashlytics 报告中获取空对象引用上的 'com.google.android.gms.internal.zzbsp.zzabx'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42609107/
总的来说，我对ruby还比较陌生，我正在为我正在创建的对象编写一些rspec测试用例。许多测试用例都非常基础，我只是想确保正确填充和返回值。我想知道是否有办法使用循环结构来执行此操作。不必为我要测试的每个方法都设置一个assertEquals。例如:describeitem,"TestingtheItem"doit"willhaveanullvaluetostart"doitem=Item.new#HereIcoulddotheitem.name.shouldbe_nil#thenIcoulddoitem.category.shouldbe_nilendend但我想要一些方法来使用
我正在尝试测试是否存在表单。我是Rails新手。我的new.html.erb_spec.rb文件的内容是:require'spec_helper'describe"messages/new.html.erb"doit"shouldrendertheform"dorender'/messages/new.html.erb'reponse.shouldhave_form_putting_to(@message)with_submit_buttonendendView本身，new.html.erb，有代码:当我运行rspec时，它失败了:1)messages/new.html.erbshou
在控制台中反复尝试之后，我想到了这种方法，可以按发生日期对类似activerecord的(Mongoid)对象进行分组。我不确定这是完成此任务的最佳方法，但它确实有效。有没有人有更好的建议，或者这是一个很好的方法？#eventsisanarrayofactiverecord-likeobjectsthatincludeatimeattributeevents.map{|event|#converteventsarrayintoanarrayofhasheswiththedayofthemonthandtheevent{:number=>event.time.day,:event=>ev
我在我的项目目录中完成了compasscreate.和compassinitrails。几个问题:我已将我的.sass文件放在public/stylesheets中。这是放置它们的正确位置吗？当我运行compasswatch时，它不会自动编译这些.sass文件。我必须手动指定文件:compasswatchpublic/stylesheets/myfile.sass等。如何让它自动运行？文件ie.css、print.css和screen.css已放在stylesheets/compiled。如何在编译后不让它们重新出现的情况下删除它们？我自己编译的.sass文件编译成compiled/t
我在我的项目中添加了一个系统来重置用户密码并通过电子邮件将密码发送给他，以防他忘记密码。昨天它运行良好(当我实现它时)。当我今天尝试启动服务器时，出现以下错误。=>BootingWEBrick=>Rails3.2.1applicationstartingindevelopmentonhttp://0.0.0.0:3000=>Callwith-dtodetach=>Ctrl-CtoshutdownserverExiting/Users/vinayshenoy/.rvm/gems/ruby-1.9.3-p0/gems/actionmailer-3.2.1/lib/action_mailer

我有一个表单，其中有很多字段取自数组(而不是模型或对象)。我如何验证这些字段的存在？solve_problem_pathdo|f|%>... 最佳答案 创建一个简单的类来包装请求参数并使用ActiveModel::Validations。#definedsomewhere,atthesimplest:require'ostruct'classSolvetrue#youcouldevencheckthesolutionwithavalidatorvalidatedoerrors.add(:base,"WRONG!!!")unlesss
我已经从我的命令行中获得了一切，所以我可以运行rubymyfile并且它可以正常工作。但是当我尝试从sublime中运行它时，我得到了undefinedmethod`require_relative'formain:Object有人知道我的sublime设置中缺少什么吗？我正在使用OSX并安装了rvm。 最佳答案 或者，您可以只使用“require”，它应该可以正常工作。我认为“require_relative”仅适用于ruby1.9+ 关于ruby-主要:Objectwhenrun
好的，所以我的目标是轻松地将一些数据保存到磁盘以备后用。您如何简单地写入然后读取一个对象？所以如果我有一个简单的类classCattr_accessor:a,:bdefinitialize(a,b)@a,@b=a,bendend所以如果我从中非常快地制作一个objobj=C.new("foo","bar")#justgaveitsomerandomvalues然后我可以把它变成一个kindaidstring=obj.to_s#whichreturns""我终于可以将此字符串打印到文件或其他内容中。我的问题是，我该如何再次将这个id变回一个对象？我知道我可以自己挑选信息并制作一个接受该信
我花了三天的时间用头撞墙，试图弄清楚为什么简单的“rake”不能通过我的规范文件。如果您遇到这种情况:任何文件夹路径中都不要有空格!。严重地。事实上，从现在开始，您命名的任何内容都没有空格。这是我的控制台输出:(在/Users/*****/Desktop/LearningRuby/learn_ruby)$rake/Users/*******/Desktop/LearningRuby/learn_ruby/00_hello/hello_spec.rb:116:in`require':cannotloadsuchfile--hello(LoadError) 最佳
