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。

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?

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。

你可以直接在Android Studio中做到这一点。只要连接你的手机,运行应用程序,让它崩溃,你就可以直接在Android Studio中查看堆栈跟踪。

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..

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");

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.
