今天用 android studio 写程序踩到这个诡异的坑：

首先介绍使用的开发工具和环境：android studio

测试机型：红米note2： android 5.0.2

是这样的：笔者程序中写的这个页面中上方是一个地图（高德地图），下方是一个listview，展示地图中的相关数据，然后今天要改造这个listview为expandableListViewV，吭哧吭哧写完了，高高兴兴等华丽丽的变化，然而 图样图森破 ，点进这个有地图的页面，显示黑屏，卡了好几秒，直接闪退回登录界面，然后报了下方的错，真是。。。招谁惹谁了。。。对了诡异的事还没说：不管你怎么修改代码，再进来这个页面就是这样了，接下来重点来了，我试着卸载掉这个app，然后重新编译安装，又可以运行地图的界面了，然而，重新随便改下界面的布局，再instance Run一下，爆炸，重复上面的报错了。当然，看报错信息应该跟jni相关，试着换个手机，同样会出现一眼改的问题，然后，试着关闭instance Run ，结果还是老样子（诡异的是之前开发这个界面就没出现过这个情况，so库是高德开放api提供的，且一直没有更换jni放置目录，而且检查data/app/应用包名/lib/arm/编译打包进的so库无异常，猜想是更新了android studio 和gradle？），现在问题还没解决，暂时先在这记录下。（解决了再更新）

2016-09-08 ：笔者今天在开发另外的安卓程序中使用高德地图api再一次遇到这个问题，不过今天有一个意外的发现："Your app does not have the latest code changes because it was restarted manually. Please run from IDE instead"，如下图，是再次运行出问题时的系统弹出框提示

这次用这段话google了一下下，然后找到一个相关的链接啦：http://stackoverflow.com/questions/36872586/android-studio-your-app-does-not-have-the-latest-code-changes ，也许是这个原因,也许不是，先更新记录下啦先。

根据stackoverflow中的讨论：得出的是android studio 的 instance run 的时候，app被手动重启，导致instance run 部署代码异常，估计跟着高德地图的jni代码部署也异常了。

解决方案：根据stackoverflow中的，Run>Clean and Re-Run ，这跟我问题描述中的解决方案一样。
