为什么 android studio 模拟器不起作用？

分类：编程问答

如何解决为什么 android studio 模拟器不起作用？

从昨天开始，android studio 设备模拟器就无法运行了。

没有改变项目的任何内容，并且在一切运行良好之前。 试图更改编译版本和目标版本、构建版本以及一些不同的 api，但它不起作用。 我卸载了 android studio，也卸载并安装了所有 sdk 工具，但到目前为止没有任何效果。尝试更改广告设置并在互联网上查找但没有找到解决方案。日志中没有任何错误或看起来可疑的东西，不知道如何解决并运行它。

当我启动应用程序时显示保持白色，只有状态栏用我选择的颜色着色。

运行：

解决方法

我解决了我的问题！ 因为我有许多不同编程状态的备份，我可以回到我制作的第一个备份并复制我在文件夹中制作的所有新内容，现在一切正常，不知道我的问题的原因，但我解决了。>

尝试关闭Instant Run：

  1. 打开设置或首选项对话框：在 Windows 或 Linux 上，从菜单栏中选择文件 > 设置。在 Mac OSX 上，从菜单栏中选择 Android Studio > 首选项。
  2. 导航到构建、执行、部署 > 即时运行。
  3. 取消选中在代码更改时重新启动活动旁边的框。 重新构建。
