My Android Studio claims that declaring the package in the manifest like this is deprecated:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="this.is.my.package">
The error message is:
Move package from Android manifest to build files
Declaration of a project's namespace using the package attribute of the Android manifest is deprecated in favour of a namespace declaration in build files.
But the button "Run selected steps" is disabled and I cannot click it.
How to fix this error message?
