Can I use a resource string for a package name?

Question

Is something like this possible?

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="@string/package_name"
      android:versionCode="1"
      android:versionName="@string/version_name">

The code above gives me an error:

C:\android-sdk\tools\ant\build.xml:539: Application package '@string/package_name' must have a minimum of 2 segments.

My strings are defined in res/strings.xml like this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">My app</string>
    <string name="version_name">1.00</string>
    <string name="package_name">com.mycompany.myapp</string>

If I replace @string/package_name with the name of the package, android:versionName seems to be set correctly.
So the question is why package name doesn't work while android:versionName works?

Edit: Is there any way to use a package name specified in external file?

Answer 1

AFAIK, you may only access XML resources using the @resource/name format for attributes defined in the android xmlns (http://schemas.android.com/apk/res/android).

As package is not defined in the android schema, it cannot access resources that way, while versionName can.
