How to add client certificate to Android?
I can send this info in http requests, but I dont know how to add a client certificate when verifying the device in a request?
How to do that?
There is no way to set the trust for client certificates at runtime. The only way you have to verify certificates using OAuth 2.0 is by calling a /token endpoint:you will get back a JSON that has info about the certificate that the device's user has supplied you (and other data, including its client secret).
If you need more info about certificates than the token endpoint has (ie you have some custom logic that you need to run against the certificates - you can not just read JSON from /token), then either: Your app should firstly make sure the user is trusted, and if that's OK, then make the actual OAuth 2.0 call.
Your app should just trust whatever comes back to it, and use any certificates found in that JSON as your basis for deciding whether to trust that user's Android client.
