重命名包并更改主要活动后应用程序崩溃

Question

我已经制作了关于旅行的应用程序，但是在我重命名包并更改了活动顺序后，我的应用程序出现了问题。 我收到错误“应用程序不断停止”。 这是我的 logcat。

我建议您使用正确的名称创建另一个项目并将所有数据传递给新项目，因为 android studio 在运行时使用您的包名称创建了许多文件和路由，但是如果您只需要更改应用程序 ID，您可以在您的 gradle 文件中更改此信息.

android {
    defaultConfig {
        applicationId "com.example.myapp"
        minSdkVersion 16
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    ...
}
