修改

<application
android:name=".MainApplication"

到

<application
android:name="com.company.mobile.MainApplication"

如果您修改了包名称，请将其替换为那个。

还要确保在 list 中导入正确的包

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:dist="http://schemas.android.com/apk/distribution"
      xmlns:tools="http://schemas.android.com/tools"
      package="com.company.mobile">
