How i can insert package name in AndroidManifest?

I write small plugin for Unity, but i need to insert package name into xml tag in AndroidManifest
How i can do it?

For example: in gradle i can to write ${applcationId} in xml tag and this placeholder will be replace on build app.

Unity 5.5 comes with Gradle build support, so you can change the build system to Gradle, and it should work by replacing the placeholder ${applicationId} with the correct package name.

Alternatively, you can create editor code that will go over the AndroidManifest.xml file and replace this value with the correct package name from your project.
