I would like introduce some "help" into my Android application to provide user some source of FAQ/this icon is what/how-to for features in my Android application.
Most android applications I seen seem to favor adding a "Help" under the Menu which will link to their help guide main landing page. The user then needs to search for the topic they need help on.
I'm thinking of something along the same line, but perhaps based on the current page in the android app the user is on, I will redirect to a specific section of the help guide to fasten the help search process a little bit.
Are they any other ways to do it (pdf, video, etc) and what is currently the best practice to implement such the "help" inside a Android application?
