... ? - Learn the standard API (IMHO, slow start) - Use different frameworks ala PhoneGAP, ionicframework (possibly fast, possible shoals and cut API) - ... something else? What do you advise ?
Where to look for sample applications (code snapshots), for example, how to work with the same Websocket on Android ..

Learn the base. You can't do anything without her. Do not see you in a short time of your application.
Or the option is to take a tutor and rehearse the same base with him. This is if self-motivation is low and you need kicks. But it will only retell you the content of developer.android.com.
Give the task to a specialist. Or saw yourself, as you study and understand.
