Android全局崩溃捕获

121 阅读 0 评论 80 点赞

我是靠谱客的博主犹豫火车，这篇文章主要介绍Android全局崩溃捕获，现在分享给大家，希望可以做个参考。

今天出了一个需求，由于APP有很多问题，尤其是崩溃，很让人头疼，所以需要可以把崩溃捕获的一个机制，然后将错误信息上传后台。这种情况我们会接入第三方，比如bugly，友盟等。但是让人头疼的是这是一个内网环境，也就是说没办法接外网，像bugly之类的第三方SDK都是要把错误日志上传到第三方的服务器的。下面是我在网上找的方案。

首先创建一个类

}

然后在Application中初始化这个工具

复制代码

CrashHandlerUtil.getInstance().init(context);

这样，在CrashHandlerUtil类的saveCrashInfo2File方法中，crashInfo就是我们要的信息，信息示例如下
