Android Navigation And Gradle 7.3.3 namespace Kapt Plugin Generated Directions Fail To Resolve Resources

Question

Since the new Android Studio Version "Chipmunk" the Gradle update helper suggests that you remove the package keyword from the AndroidManifest.xml and instead use a object namespace in the android block inside the app-level build.gradle.

However, using the recent version 2.4.2 and also with the version 2.5.0-rc01 of the standard navigation library, the Directions generated by the kapt plugin no longer import the correct resource path when a different applicationId is set for a build flavor.

For example if my default package name is my.package.com and I have a flavor called dev which is declared with a applicationId "my.package.com.dev" and the namespace is set to my.package.com, the generated directions all throw build errors: Unresolved reference: R.

Has anyone else stumbled over this issue and is there anything we can do to fix this?

I had to remove the namespace and put back in the package parameter in my AndroidManifest to resolve this issue, but that doesn't seem to be right.

Answer 1

I've just noted that this is a reported issue here. So adding back package name in manifest resolved the issue for the time being for my self.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.myapp.gcapp"

I have multiple modules in my app and had to add namespace to each module's build.gradle file.
