when my gradle was 3.6.0 I was getting build gradle error of android r8 is deprecated so I changed version to 3.4.0 . Now I am getting this error. I tried all but stuck here for a long time. Even I tried changing file name to launcher-release through launcher template still it is building launcher.abb

Add following code to default config of LauncherTemplate.gradle

 tasks.whenTaskAdded { task ->
        if (task.name.startsWith("bundle")) {
            def renameTaskName = "rename${task.name.capitalize()}Aab"
            def flavor = task.name.substring("bundle".length()).uncapitalize()
            tasks.create(renameTaskName, Copy) {
                def path = "${buildDir}/outputs/bundle/${flavor}/"
                from(path)
                include "launcher.aab"
                destinationDir file("${buildDir}/outputs/bundle/${flavor}/")
                rename "launcher.aab", "launcher-release.aab"
            }

            task.finalizedBy(renameTaskName)
        }
    }

Remember you have to change .abb names in code according to what you need.

                    include "launcher.aab"
                  
                    rename "launcher.aab", "launcher-release.aab"
