How To Oauth 2.0 With Retrofit Android

I'm using Retrofit library and I wanted to implement OAuth 2.0 on every API call in order to authenticate those calls. How can I achieve that? Can you explain me step by step? I ha

Solution 1:

I highly recommend you to check u2020 source code. You can achieve this with a OkHttp interceptor (Retrofit 1.x or Retrofit 2.x) or a RequestInterceptor if you stay with Retrofit 1.x.

Solution 2:

I think for the oAuth 2.0 process its better if you open directly the browser and once its done it will redirect to the redirect_url specified. You will need to register the redirect_url in your manifest as a intent-filter for the activity that will manage the response of the server.
