updated android icon. Used the Android Asset Studio - Launcher icon generator
display a small separator line in Android actionBar
fix report ignores additional report params (eg in Goals)
makes sure to display 0 value because API returns visits as string and actions as number
fix selection style is blue
make sure loading screen is always rendered in viewport in case of orientation changes
render a report overview box only when it is within the viewport because it takes too long to render all boxes in parallel otherwise. Unfortunately, it stutters a bit when scrolling because we start rendering then but this should still be better than rendering all boxes at once
make a pause of one second after each request, otherwise the server might response with failures when executing all requests at once
add Piwik license header to i18n files
updated translations
update window title when language changes
fix report chooser + composite report does not refresh when language changes
