My small white, need to develop an app on the job recently through a call to test the android third-party API, mainly is the Java API (a jar package), and C API.
Check information to app development has a native app and hybrid app, individuals are more likely mixed app development, but I don't know whether hybrid app can go to call the third party in the android API,
Note: API is developed by a third party to sell to other companies, other companies to develop the app can go to call and get the service application program interface,
