是否有任何 sdk 可以记录生产应用程序中的异常、事件和错误？

Question

我想在生产期间捕获我的应用程序中的所有未 expected/undesirable 事件。我想要一些可以将错误日志文件发送到服务器的东西，我可以通过 Web 应用程序轻松读取它。你知道这类事情吗？

Answer 1

使用 Mint 获取每个异常日志或使用 MonkeyTalk 获取应用程序的所有日志记录。

Answer 2

如果您需要获取所有 unexpected/undesirable 异常。

请把这一行放在你的类中，你需要得到 Log.

ErrorReporter.getInstance().Init(YOURACTIVITY.this);

你可以使用这个ErrorReporter.Class
