如何从我的Android应用程序中获得崩溃数据(至少堆栈跟踪)?至少在我自己的设备上工作时可以通过电缆检索,但理想的情况是,从我的应用程序在野外运行的任何实例中都可以,这样我就可以改进它,使它更可靠。

谷歌Firebase是谷歌最新的(2016)方式,为您提供崩溃/错误数据在您的手机。 将它包含在您的构建中。Gradle文件:
compile 'com.google.firebase:firebase-crash:9.0.0'
致命崩溃会自动记录,不需要用户输入,你也可以记录非致命崩溃或其他事件,如下所示:
try
{
}
catch(Exception ex)
{
FirebaseCrash.report(new Exception(ex.toString()));
}

我是Bugsnag的创始人之一,我们正是为此目的而设计的。Bugsnag自动捕获Android应用程序中未处理的异常,并将它们发送到我们的仪表板,在那里您可以优先修复并深入诊断信息。
以下是在选择或构建崩溃报告系统时需要考虑的一些重要事项,以及一些代码片段:
自动检测未处理的异常(示例代码) 收集诊断数据,如内存使用情况、设备信息等(示例代码) 根据根本原因有效地将崩溃组合在一起 允许您跟踪用户在每次崩溃前采取的操作,以帮助重现(示例代码)
如果你想在Android上看到一些关于崩溃处理/报告的最佳实践,你可以查看Bugsnag的崩溃报告库的完整源代码,它是完全开源的,可以自由地把它拆开,并在你自己的应用程序中使用!
谷歌改变了你实际得到的崩溃报告的数量。以前你只能得到手动报告的错误报告。
自从上次开发者大会和Android Vitals的引入,你也会从用户那里得到崩溃报告,这些用户已经启用了共享诊断数据。
您将看到从用户选择自动共享使用情况和诊断数据的Android设备收集的所有崩溃。可获得前两个月的数据。

我还找到了一个更好的web应用程序来跟踪错误报告。
https://mint.splunk.com/
配置步骤少。
使用上面的链接登录或注册并配置。一旦你创建了一个应用程序,他们将提供如下所示的一行来配置。
Mint initAndStartSession (YourActivity。这“api_key”);
在应用程序的build.gradl中添加以下内容。
android { ... 存储库{ Maven {url "https://mint.splunk.com/gradle/"} } ... } 依赖关系{ ... 编译”com.splunk.mint:薄荷:4.4.0” ... }
添加上面复制的代码,并将其添加到每个活动中。 Mint.initAndStartSession (YourActivity。这个,”api_key”);
就是这样。你登录并进入应用程序仪表板,你会得到所有的错误报告。
希望它能帮助到别人。
感谢资源在Stackoverflow中帮助我找到这个答案。
你可以直接在电子邮件中找到远程Android崩溃报告。记住你必须把你的电子邮件放在CustomExceptionHandler类中。
public static String sendErrorLogsTo = "tushar.pandey@virtualxcellence.com" ;
步骤:
1)在onCreate你的活动使用这段代码。
if(!(Thread.getDefaultUncaughtExceptionHandler() instanceof CustomExceptionHandler)) {
Thread.setDefaultUncaughtExceptionHandler(new CustomExceptionHandler(this));
}
第二)使用(rrainn)的CustomExceptionHandler类的重写版本,根据我的phpscript。

If your app is being downloaded by other people and crashing on remote devices, you may want to look into an Android error reporting library (referenced in this SO post). If it's just on your own local device, you can use LogCat. Even if the device wasn't connected to a host machine when the crash occurred, connected the device and issuing an adb logcat command will download the entire logcat history (at least to the extent that it is buffered which is usually a loooot of log data, it's just not infinite). Do either of those options answer your question? If not can you attempt to clarify what you're looking for a bit more?
