Question

I want to start a new activity when Facebook login completes that happens in a DialogListener. Login done successfully No error comes but activity doesn’t start. If you require logcat I can email you.
Following is my code.

Here is My HomeActivity

package com.example.faceb;

import com.facebook.android.AsyncFacebookRunner;
import com.facebook.android.Facebook;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class HomeActivity extends Activity implements OnClickListener{
    private static final String TAG = "Facebook";
    private Button mLogin, mLogout, mShare;
    private Facebook facebook;
    private AsyncFacebookRunner abRunner;

    public boolean flag;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.activity_home);

        facebook = new Facebook("479652662068145");
        abRunner = new AsyncFacebookRunner(facebook);

        mLogin= (Button) findViewById(R.id.Login);
        mLogout= (Button) findViewById(R.id.Logout);

        mLogin.setOnClickListener(this);
        mLogout.setOnClickListener(this);     
    }

    @Override
    public void onClick(View v){
        int id = v.getId();
        switch(id){
            case R.id.Login:
                FacebookLoginDialog login = new FacebookLoginDialog(this);         
                facebook.authorize(this, login);
                if (func()==true)         
                {
                    Intent i = new Intent(this, SearchActivity.class);
                    startActivity(i);
                }
                break;
            case R.id.Logout:
                FacebookLogoutRequest logout = new FacebookLogoutRequest(this);
                abRunner.logout(this, logout);
                Toast toast = Toast.makeText(this, "You Are Logged Out", Toast.LENGTH_SHORT);
                toast.show();
                break;
            default:
                break;
        }
    }

    public static boolean func() {
        return true;
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_home, menu);
        return true;
    }
}

And Following my FacebookLoginDialog Class

public class FacebookLoginDialog implements DialogListener{
    @Override
    public void onComplete(Bundle values) {
        HomeActivity.func();
    }

    @Override
    public void onFacebookError(FacebookError e) {
        // TODO Auto-generated method stub
    }

    @Override
    public void onError(DialogError e) {
        // TODO Auto-generated method stub  
    }

    @Override
    public void onCancel() {
        // TODO Auto-generated method stub  
    }
}

This dialog starts on a button click which is in my HomeActivity. Please help I searched a lot and tried but unable to solve this issue.

Answer 1

I think instead of starting the dialog on button click, u can start the activity, which u want to start after login. Then call the dialog inside the onCreate() of the new activity. So that u can just close the dialog in onComplete() and automatically the new screen will appear. Just keep a flag in the activity and set it to true only when the login succeeds. So that u can finish the new activity if the flag is false after the dialog get closed.
