I added this line to the manifest xml file of my app, according to documentation for optimizing for ChromeOS Android app publishing
<uses-feature android:name="android.hardware.touchscreen" required="false" />
but I get "Attribute is missing the Android namespace prefix..." for the "required" attribute.
If I add the Android: namespace prefix it works but I do not know if it is the right thing to do because I copied that line from the official web-page:
https://developer.android.com/topic/arc/index.html
and it has not the prefix.
It is right to add the prefix?
