Lint is complaining about the new launcher icons in 'res/mipmap-anydpi-v26'
are not in PNG format. These are now defined in XML and lint is probably
not aware of the new XML format for API v26 and higher.
This also fixes usage of "android:layout_marginEnd". Which is only
supported from API v17.
Added running lintFullRelease to travis-CI build.
