One common issue in newer Android version is the new Lint 16.0.0 which added to let you see errors, bad practice and coding mishaps. One of these will requirement you to replace “-”
Replace “-” with an “en dash” character (–, &&;#8211;) ?

It will break it and it will stop Google Analytics from recognising the ID.
