在使用这些技术之一重命名包之后，可能会开始看到错误。

如果/当你的R.java没有正确生成时，你会在项目中收到很多错误，比如错误：找不到符号类R，以及错误：包R不存在。

记住检查应用程序清单xml。清单包名称必须与实际包名称匹配。R.java似乎是从应用程序清单生成的，如果不匹配，可能会导致这些错误。

记住检查<manifestpackage=“com.yourcompany.coolapp”>中的package属性匹配

右键单击package->refactor并更改名称。

您也可以在清单中更改它。有时，如果您更改包名，但在创建.apk文件后，它会显示不同的包名。此时，检查build.gradle文件中的“applicationId”。

按Ctrl+Shift+R用新包装替换旧包装。右键单击程序包名称。重构>重命名并重命名为新的

右键单击包名称->Refactor->重命名->输入包名称->单击“Refactor”。不要编辑“app”文件夹下除“build.gradle”以外的任何构建文件。
