plugins for my android app [duplicate]

This question already has answers here: 开发者_运维百科 How to release application plugin using Android Market? (2 answers) Closed 2 years ago.

I'm trying to find out what is the right method of enabling plugins or extensions for my android application. As with any other plug-able application I want: 1) list of installed plugins 2) ability to call methods (which may or may not have UI) implemented in plugins

Goal is to isolate functionality which is not essential.

Its not really clear what you mean. If you want to develop your own reusable app components using and Android Library Project maybe what you want see here, or else you may want to look into how Content Providers and Intents are used to use other installed applications on the device see here
