The Android documentation tells me that I can access a string from another package by using the \"package name\", whatever that means:
@[
Name your resource in your package as com.globalmentor.android.app_applicationlistactivity_lab and not just app_applicationlistactivity_lab.
....
Then you can access it from XML as
"@string/com.globalmentor.android.app_applicationlistactivity_lab"
and programmatically by
getResources().getString(R.string.com_globalmentor_android_app_applicationlistactivity_lab);
without conflicts.
