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Play开发者控制台实际上为你提供了那些已经崩溃和发送报告的应用程序的堆栈跟踪,它也有一个非常好的图表来帮助你查看信息,参见下面的例子:

有个机器人图书馆叫夏洛克。它为您提供完整的崩溃报告以及设备和应用程序信息。 无论何时发生崩溃,它都会在通知栏中显示一个通知,并且在单击该通知时,它会打开崩溃详细信息。您还可以通过电子邮件或其他共享选项与他人分享崩溃详情。
安装
android {
dataBinding {
enabled = true
}
}
compile('com.github.ajitsing:sherlock:1.0.0@aar') {
transitive = true
}
Demo
我在这里做了我自己的版本: http://androidblogger.blogspot.com/2009/12/how-to-improve-your-application-crash.html
这基本上是相同的事情,但我使用邮件而不是http连接来发送报告,更重要的是,我添加了一些信息,如应用程序版本,操作系统版本,手机型号,或可用内存到我的报告…
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。

We use our home-grown system inside the company and it serves us very well. It's an android library that send crash reports to server and server that receives reports and makes some analytics. Server groups exceptions by exception name, stacktrace, message. It helps to identify most critical issues that need to be fixed. Our service is in public beta now so everyone can try it. You can create account at http://watchcat.co or you can just take a look how it works using demo access http://watchcat.co/reports/index.php?demo.
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();
}
}
