将我的项目移动到另一台计算机后，当尝试运行代码（完全相同的工作代码来自第一台计算机）时，应用程序崩溃。
这是控制台中的错误：

我搜索了同样问题的其他人，大多数答案都是关于不整体播放服务但只需要部分，但我已经这样做了 apply plugin：'com.android.application'

问题可能就在这里：我的包名是 com.dean.booktown
不是 com.dean.booktown-1
如果这确实是问题，我在哪里找到错误来修复它，为什么它首先发生？
非常感谢，
迪安
答案 0 :(得分：0)
com.dean.booktown-1
这实际上是安装APK的文件夹
是否安装了SDK和Google工具和库？你应该仔细检查一下，因为你交换了环境。
编辑; 从this question开始，是否启用了MultiDex？ MultiDex使您的应用程序可以使用许多类。要添加它，请参阅答案＃2
