CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_sign_in_user);



     LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {


            GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject object, GraphResponse response) {
                    try {
                        Log.i("RESAULTS : ", object.getString("email"));
                    }catch (Exception e){

                    }
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "email");
            request.setParameters(parameters);
            request.executeAsync();

        }

        @Override
        public void onCancel() {

        }

        @Override
        public void onError(FacebookException error) {
            Log.i("RESAULTS : ", error.getMessage());
        }
    });


}

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


boolean isEmailValid(CharSequence email) {
    return android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches();
}

public void signupwith_facebook(View view) {

    LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile","email"));
}
}
