出于示例应用程序和调试目的，我使用一个简单的解决方案，该解决方案使我可以将stacktrace写入设备的sd卡和/或将其上传到服务器。该解决方案的灵感来自Project android-remote-stacktrace（特别是保存到设备和上载到服务器的部件），我认为它解决了Soonil提到的问题。它不是最佳选择，但是它可以工作，如果您想在生产应用程序中使用它，则可以对其进行改进。如果决定将堆栈跟踪上载到服务器，则可以使用php脚本（index.php）查看它们。如果您有兴趣，可以在下面找到所有源代码-一个Java类用于您的应用程序，两个可选php脚本，用于托管上传的stacktrace的服务器。
在上下文（例如主活动）中，调用

Thread.setDefaultUncaughtExceptionHandler(new CustomExceptionHandler(
"/sdcard/<desired_local_path>", "http://<desired_url>/upload.php"));
}

final Writer result = new StringWriter();
final PrintWriter printWriter = new PrintWriter(result);

printWriter.close();
String filename = timestamp + ".stacktrace";

writeToFile(stacktrace, filename);
