Answer 1

If someone is looking for this but for Google account using FirebaseAuth. I have found a workaround for this. If you detail the picture URL:

https://lh4.googleusercontent.com/../.../.../.../s96-c/photo.jpg

The /s96-c/ specifies the image size (96x96 in this case)so you just need to replace that value with the desired size.

String url= FirebaseAuth.getInstance().getCurrentUser().getPhotoUrl();
url = url.replace("/s96-c/","/s300-c/");

You can analyze your photo URL to see if there is any other way to change its size.

As I said in the begining, this only works for Google accounts. Check @Mathias Brandt 's answer to get a custom facebook profile picture size.

EDIT 2020:

Thanks to Andres SK and @alextouzel for pointing this out. Photo URLs format have changed and now you can pass URL params to get different sizes of the picture. Check https://developers.google.com/people/image-sizing.

Note: From Graph API v8.0 you must provide the access token for every UserID request you do.

Hitting the graph API:

https://graph.facebook.com/<user_id>/picture?height=1000&access_token=<any_of_above_token>

With firebase:

FirebaseUser user = mAuth.getCurrentUser();
String photoUrl = user.getPhotoUrl() + "/picture?height=1000&access_token=" +
  loginResult.getAccessToken().getToken();

You get the token from registerCallback just like this

       LoginManager.getInstance().registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            FirebaseUser user = mAuth.getCurrentUser();
            String photoUrl = user.getPhotoUrl() + "/picture?height=1000&access_token=" + loginResult.getAccessToken().getToken();
        }

        @Override
        public void onCancel() {
            Log.d("Fb on Login", "facebook:onCancel");
        }

        @Override
        public void onError(FacebookException error) {
            Log.e("Fb on Login", "facebook:onError", error);
        }
    });

This is what documentation says:

Beginning October 24, 2020, an access token will be required for all UID-based queries. If you query a UID and thus must include a token:

• use a User access token for Facebook Login authenticated requests
• use a Page access token for page-scoped requests
• use an App access token for server-side requests
• use a Client access token for mobile or web client-side requests

We recommend that you only use a Client token if you are unable to use one of the other token types.
