LoginScreenlet oauth Exception

Expert Beiträge: 483 Beitrittsdatum: 31.07.10 Neueste Beiträge
Hi

I am using Liferay 6.2 and Liferay screens 1.3.0.

I am trying to use OAuth authentication but getting java.lang.NullPointerException: Attempt to invoke virtual method 'int com.liferay.mobile.screens.auth.BasicAuthMethod.ordinal()' on a null object reference. OAuth Provider EE plugin is deployed on liferay server. Basic authentication is working fine.


 <com.liferay.mobile.screens.auth.login.loginscreenlet android:id="@+id/liferay_login" android:layout_width="match_parent" android:layout_height="wrap_content" app:layoutId="@layout/login_default" app:basicAuthMethod="email" app:oauthConsumerKey="xxxx" app:oauthConsumerSecret="xxxx" />


public class MainActivity extends AppCompatActivity implements LoginListener, View.OnClickListener {

    private LoginScreenlet loginScreenlet;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });

        loginScreenlet = (LoginScreenlet) findViewById(R.id.liferay_login);
        loginScreenlet.setListener(this);

        findViewById(R.id.liferay_sign_up_button).setOnClickListener(this);
        findViewById(R.id.liferay_forgot_button).setOnClickListener(this);
    }

   @Override
    protected void onActivityResult(final int requestCode,final int resultCode,final Intent data)
    {
        super.onActivityResult(requestCode,resultCode,data);
        if(resultCode == Activity.RESULT_OK)
        {
            loginScreenlet.sendOAuthResult(resultCode, data);
        }
    }

    @Override
    public void onLoginSuccess(User user) {
        Toast.makeText(MainActivity.this, "User Login Successful", Toast.LENGTH_SHORT).show();
        startActivity(new Intent(this, home.class));

    }

    @Override
    public void onLoginFailure(Exception e) {
        Toast.makeText(MainActivity.this, "Login Failed", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onClick(View v) {
        if(v.getId() == R.id.liferay_sign_up_button)
        {
            startActivity(new Intent(this, SignUpActivity.class));
        }
        else if(v.getId() == R.id.liferay_forgot_button)
        {
            startActivity(new Intent(this, ForgotPasswordActivity.class));
        }

    }
}

Yes, there is a small bug in Liferay Screens (it can be easily overridden by a custom view) and an incompatibility version problem between Liferay Screens and the Mobile SDK emoticon

We're ironing the version problem right now, if you need the OAuth support right now, I can try to fix it in the 1.3.1 branch...
