All functionality is encapsulated in the AuthenticationActivity class. Calling it requires just a couple lines of code:

Intent authActivity = new Intent(MainActivity.this,
                                 com.auth0.sdk.auth0sample.AuthenticationActivity.class);

AuthenticationActivitySetup setup;
//setup = new AuthenticationActivitySetup(Tenant, ClientID, Callback, Connection);
setup = new AuthenticationActivitySetup(Tenant, ClientID, Callback);

authActivity.putExtra(AuthenticationActivity.AUTHENTICATION_SETUP, setup);

startActivityForResult(authActivity, AuthenticationActivity.AUTH_REQUEST_COMPLETE);
AuthenticationActivity is an Android Activity and responses are handled with the standard onActivityResult method. If authentication is successful, resultCode will be equal to RESULT_OK, and an object of type AuthenticationActivityResult will be available. It contains two properties: access_token and JsonWebToken:

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent authActivityResult) {
    super.onActivityResult(requestCode, resultCode, authActivityResult);

    switch(requestCode)
    {
        case AuthenticationActivity.AUTH_REQUEST_COMPLETE:
            if(resultCode==RESULT_OK)
            {
                AuthenticationActivityResult result;
                result = (AuthenticationActivityResult) authActivityResult.getSerializableExtra(AuthenticationActivity.AUTHENTICATION_RESULT);

                // result have two properties `accessToken` and `JsonWebToken`. You can use the `accessToken` to call the Auth0 API and retrieve the profile of the user that just logged in
                // the `JsonWebToken` is a signed JSON that can be sent to your APIs

                String userInfoUrl = String.format("https://linez.auth0.com/userinfo?access_token=%s", result.accessToken);
                new AsyncTask<String, Void, JSONObject>() {
                    @Override
                        protected JSONObject doInBackground(String... url) {
                           JSONObject json = RestJsonClient.connect(url[0]);

                           return json;
                        }

                    @Override
                    protected void onPostExecute(JSONObject user) {
                        try {
                                ((TextView) findViewById(R.id.user)).setText(user.toString(2));
                        } catch (JSONException e) {
                                e.printStackTrace();
                        }
                    }
                }.execute(userInfoUrl);
            }
            break;
    }
}
