Android Twitter4j

I want to create a application 开发者_开发知识库where user can login with twitter account and whatever activity he does (depending on other cases) should be tweeted.

Now since twitter has removed basic authentication how to achieve this ????

Any help will be appreciated

You can use third party libraries to perform OAuth. See the following threads to get some insight on OAuth and how to perform 3 legged authentication:
1. Some questions about OAuth and Android
2. OAuth on Android
3. OAuth + TWitter on Android with code

Hope that helps...
