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。


当前回答

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()));
}

您也可以尝试[BugSense]原因:垃圾邮件重定向到另一个url。BugSense收集并分析所有崩溃报告,并为您提供有意义的可视化报告。它是免费的,而且只需要一行代码就可以进行集成。

这是非常野蛮的,但是可以在任何地方运行logcat,所以一个快速而肮脏的hack是在任何捕获块中添加getRuntime()。Exec ("logcat >> /sdcard/logcat.log");

我知道这个问题太老了,希望我的回答对其他有同样问题的人有帮助…

试试Crashlytics吧。它将深入了解所有崩溃的所有设备有你的应用程序,并通过电子邮件发送通知给你..最好的部分是它完全免费使用..

好吧,我看了rrainn和Soonil提供的样本,我找到了一个解决方案 这不会破坏错误处理。

我修改了CustomExceptionHandler,以便它从我们关联的新线程中存储原始的UncaughtExceptionHandler。在新的“uncaughtException”的末尾- 方法,我只是使用存储的UncaughtExceptionHandler调用旧函数。

在DefaultExceptionHandler类中,你需要这样的东西:

public class DefaultExceptionHandler implements UncaughtExceptionHandler{
  private UncaughtExceptionHandler mDefaultExceptionHandler;

  //constructor
  public DefaultExceptionHandler(UncaughtExceptionHandler pDefaultExceptionHandler)
  {
       mDefaultExceptionHandler= pDefaultExceptionHandler;
  }
  public void uncaughtException(Thread t, Throwable e) {       
        //do some action like writing to file or upload somewhere         

        //call original handler  
        mStandardEH.uncaughtException(t, e);        

        // cleanup, don't know if really required
        t.getThreadGroup().destroy();
  }
}

在http://code.google.com/p/android-remote-stacktrace上对代码进行了修改 你有一个很好的工作基地,登录到你的web服务器或 sd卡。

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。
