Mobile Network ‘Know-How’ for 3rd party developers
Objective: The “developer guidelines” document
aims to create awareness amongst new/novice developers while encouraging better development habits.
Provides a set of key principles (some independent of the underlying platform) covering:-
AsynchronyConnection Loss and Error HandlingCachingEfficient Traffic UsageCompressionBackground/Foreground ModesSecurity
Scope : Targeted at Android, Windows Mobile &
iOS
