我过去2个月一直在使用Android工作室和模拟器，而且工作得很好而且速度很快。
现在，一旦我在Android工作室运行时关闭了我的笔记本电脑，我就不知道这是否是造成这种情况的原因。
现在，当我运行我的应用程序时，Android显示器变得疯狂，当我在我的设备中执行此操作时，它不会发生，仅在AVD中。
P.S。：我已经尝试重建，使缓存无效并重新启动，重新安装AVD，重新安装android studio（使用SDK完全卸载）但问题仍然存在。 （这里是日志（不是完整的logcat），设备启动就像2分钟后，早些时候曾经是10秒，然后是黑屏）

我设法通过从Android Studio上的SDK管理器卸载Intel HAXM并从Intel HAXM site下载最新版本并直接在操作系统中安装来解决此问题。我还将zip存档上的所有文件复制到路径C:\Users\<your_user_name>\AppData\Local\Android\sdk\extras\intel，以确保AVD检测到文件。
希望这有帮助！

尝试在不同的路径中构建新的模拟器。并且最好使用另一种手机型号。正常图像没问题，64位图像没用。
