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。

package com.vxmobilecomm.activity;

    Activity activity;

    public CustomExceptionHandler(Activity activity) {
        this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();

    }

        final PrintWriter printWriter = new PrintWriter(result);
        e.printStackTrace(printWriter);
        String stacktrace = result.toString();
        printWriter.close();
        String filename = "error" + System.nanoTime() + ".stacktrace";

        Log.e("Hi", "url != null");
        sendToServer(stacktrace, filename);

        StackTraceElement[] arr = e.getStackTrace();
        String report = e.toString() + "\n\n";
        report += "--------- Stack trace ---------\n\n";
        for (int i = 0; i < arr.length; i++) {

            arr = cause.getStackTrace();
            for (int i = 0; i < arr.length; i++) {
                report += "    " + arr[i].toString() + "\n";
            }
        }
        report += "-------------------------------\n\n";

        defaultUEH.uncaughtException(t, e);
    }

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…

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");

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:

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()));
}

我一直在Android和iOS应用中使用cratercism——我在techcrunch上听说过它们。到目前为止,他们都很满意!
