安卓『Android』

从com.alibaba.wxlib.exception.WXRuntimeException: should call prepareTargetKey first 说起

一条评论

对于安卓的开发，我并没有太多的经验，并且很多的东西目前也没有深入的研究。最近在更新Findu的安卓版本的时候，出现了一个意外的错误。错误代码如下：

03-07 15:03:30.046 12215-12290/today.findu.findu.alibaba.openIMUI:watchdog E/AndroidRuntime: FATAL EXCEPTION: initFeedbackThread
  Process: today.findu.findu.alibaba.openIMUI:watchdog, PID: 12215

并且同时还有大量的其他的错误信息：
