I have had issues before with this so I normally just create a new project and just copy all the classes, drawables, etc from the old project into the new project.

我之前遇到过这个问题，所以我通常只是创建一个新项目，然后将旧项目中的所有类、可绘制对象等复制到新项目中。

Easiest way to do this is to choose the 'open an existing project' option, find your project, and then find the 'app' folder. Click on this to highlight it and then click 'Ok'. This will then import your complete project

最简单的方法是选择“打开现有项目”选项，找到您的项目，然后找到“应用程序”文件夹。单击它以突出显示它，然后单击“确定”。这将导入您的完整项目
