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。

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。

其他回答

可以使用Thread.setDefaultUncaughtExceptionHandler()处理这些异常,但是这似乎与Android处理异常的方法相混淆。我尝试使用这样的处理程序:

private class ExceptionHandler implements Thread.UncaughtExceptionHandler {
    @Override
    public void uncaughtException(Thread thread, Throwable ex){
        Log.e(Constants.TAG, "uncaught_exception_handler: uncaught exception in thread " + thread.getName(), ex);

        //hack to rethrow unchecked exceptions
        if(ex instanceof RuntimeException)
            throw (RuntimeException)ex;
        if(ex instanceof Error)
            throw (Error)ex;

        //this should really never happen
        Log.e(Constants.TAG, "uncaught_exception handler: unable to rethrow checked exception");
    }
}

然而,即使重新抛出异常,我也无法获得所需的行为,即记录异常,同时仍然允许Android关闭组件,所以我在一段时间后放弃了它。

刚开始使用ACRA https://github.com/ACRA/acra使用谷歌形式作为后端,它非常容易设置和使用,这是默认的。

但是发送报告到谷歌表单将被弃用(然后删除): https://plus.google.com/118444843928759726538/posts/GTTgsrEQdN6 https://github.com/ACRA/acra/wiki/Notice-on-Google-Form-Spreadsheet-usage

无论如何,可以定义自己的发件人 https://github.com/ACRA/acra/wiki/AdvancedUsage#wiki-Implementing_your_own_sender 例如,你可以试着给发件人发电子邮件。

用最少的努力就可以将报告发送到bugsense: http://www.bugsense.com/docs/android#acra

对于另一个崩溃报告/异常跟踪服务检查Raygun。io -它有一堆很好的逻辑处理Android崩溃,包括体面的用户体验时,将其插入到你的应用程序(两行代码在你的主活动和几行XML粘贴到AndroidManifest)。

当你的应用程序崩溃时,它会自动抓取堆栈跟踪,硬件/软件的环境数据,用户跟踪信息,任何你指定的自定义数据等。它异步地将其提交给API,这样就不会阻塞UI线程,如果没有可用的网络,它会将其缓存到磁盘。

免责声明:我构建了Android提供商:)

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。

您还可以为它使用整个(简单的)服务,而不仅仅是库。我们公司刚刚为此发布了一项服务:http://apphance.com。

It has a simple .jar library (for Android) that you add and integrate in 5 minutes and then the library gathers not only crash information but also logs from running application, as well as it lets your testers report problems straight from device - including the whole context (device rotation, whether it is connected to a wifi or not and more). You can look at the logs using a very nice and useful web panel, where you can track sessions with your application, crashes, logs, statistics and more. The service is in closed beta test phase now, but you can request access and we give it to you very quickly.
