Facebook Login Issue in android

I'm implementing Facebook Login in my android app . The problem is When I run the app , it redirects to the facebook login page on the click of a button in my main activity . When I enter the credentials , a white page is displayed and nothing happens . Also , if I run the app a second time , only the blank page shows up . I tried to toggle on/off the single sign on functionality in the developer settings page of facebook , but it didn't help . Here's my code of the Facebook Login activity .
public class FacebookLogin extends Activity {
// Your Facebook APP ID
private static String APP_ID = "xxxxxxx"; // Replace with your App
// ID
// Instance of Facebook Class
private Facebook facebook = new Facebook(APP_ID);
private AsyncFacebookRunner mAsyncRunner;
String FILENAME = "AndroidSSO_data";
private SharedPreferences mPrefs;
#SuppressWarnings("deprecation")
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mAsyncRunner = new AsyncFacebookRunner(facebook);
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = cm.getActiveNetworkInfo();
if (networkInfo != null && networkInfo.isConnected()) {
// Start AsyncTASK here
loginToFacebook();
} else {
DialogClass
.createDAlertDialog(
FacebookLogin.this,
"Please Check Internet Connection \n Please Turn on Internet",
true);
}
}
/**

#SuppressWarnings("deprecation")
public void loginToFacebook() {
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if (access_token != null) {
facebook.setAccessToken(access_token);
Log.d("FB Sessions", "" + facebook.isSessionValid());
}
if (expires != 0) {
facebook.setAccessExpires(expires);
}
if (!facebook.isSessionValid()) {
facebook.authorize(this,
new String[] { "email", "publish_stream" },
new DialogListener() {
#Override
public void onCancel() {
// Function to handle cancel event
}
#Override

// Function to handle complete event
// Edit Preferences and update facebook acess_token
SharedPreferences.Editor editor = mPrefs.edit();
editor.putString("access_token",
facebook.getAccessToken());
editor.putLong("access_expires",
facebook.getAccessExpires());
editor.commit();
}
public void onAuthFail(String error) {

Toast.makeText(getApplicationContext(),

}

#SuppressWarnings("deprecation")
public void logoutFromFacebook() {
mAsyncRunner.logout(this, new RequestListener() {
#Override

I implemented that same for windows phone application. I used to face the same problem. But got it correct.

You could use this link to check the code and run it in similar fashion for android platform. Logic is the same.

Unable to use facebook login in android device

I have same issue mentioned in this stack overflow question. But couldn't find the solution. My problem is when I use facebook login in my android device(which is not installed facebook app), my app works as expected. If I install the facebook application my code doesn't work anymore and It throws the error "Login failed. Please contact the maker of this app and ask them to report issue #1118578 to Facebook". My code is posted below
private Facebook facebook = new Facebook(APP_ID);
private AsyncFacebookRunner mAsyncRunner;
String FILENAME = "AndroidSSO_data";
private SharedPreferences mPrefs;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mAsyncRunner = new AsyncFacebookRunner(facebook);
loginToFacebook();
}
#SuppressWarnings("deprecation")
public void loginToFacebook() {
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if (expires != 0) {
facebook.setAccessExpires(expires);
}
if (!facebook.isSessionValid()) {
facebook.authorize(this,
new String[] { "email", "publish_stream" },
new DialogListener() {
#Override
public void onCancel() {
// Function to handle cancel event

editor.commit();
getProfileInformation();
} }); } }
#Override

String name1 = arr[0];
String name2 = arr[1];
Intent intent = new Intent(FacebookLogin.this, UserAccount.class);
/*Sending some arguments*/
Bundle bundle = new Bundle();
bundle.putString("UserName",name1);
bundle.putString("Id", email);
intent.putExtras(bundle);
logoutFromFacebook();
startActivity(intent); }
});
} catch (JSONException e) {

Please anyone tell me how can I avoid this error...

Try adding this to your OnComplete
params.putString("caption",sh);

Are you sure that you are using Facebook SDK 3?
According to these lines:
private Facebook facebook = new Facebook(APP_ID);
private AsyncFacebookRunner mAsyncRunner;
I think you are using old SDK which so many of methods are deprecated.

Facebook Android Tutorial logout

I am following this tutorial. I got as far as to the point you retrieve the access token from the savedPreferences and then created a logout button. The problem is, it seems I access_token is always correct, no matter if I logout from my app or even from Facebook app.
This is my code:
public class MainActivity extends Activity {
private String TAG = MainActivity.class.getName();
Facebook mFacebook = new Facebook("whatever");
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(mFacebook);
private SharedPreferences mPrefs;
//UI elements
private ImageButton fbLoginButton;
private Button getInfoButton;
private Button fbLogoutButton;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if(access_token != null) {
Log.d(TAG, "Token found. Setting token " + access_token);
mFacebook.setAccessToken(access_token);
}
if(expires != 0) {
Log.d(TAG, "Setting expire " + expires);
mFacebook.setAccessExpires(expires);
}
if(!mFacebook.isSessionValid()) {
mFacebook.authorize(this, new String[] {"email", "read_friendlists" }, new DialogListener() {
#Override
public void onComplete(Bundle values) {
SharedPreferences.Editor editor = mPrefs.edit();
editor.putString("access_token", mFacebook.getAccessToken());
editor.putLong("access_expires", mFacebook.getAccessExpires());
editor.commit();
Log.d(TAG, "Logging you in");
}
#Override
public void onFacebookError(FacebookError error) {
Log.d(TAG, "Facebook error: " + error.getMessage() );
}
#Override
public void onError(DialogError e) {
Log.d(TAG, "Error: " + e.getMessage());
}
#Override
public void onCancel() {
Log.d(TAG, "User Canceled");
}
});
}
else{
Toast.makeText(this, "Already logged in", Toast.LENGTH_LONG).show();
}
fbLoginButton = (ImageButton) findViewById(R.id.buttonFBLogin);
getInfoButton = (Button) findViewById(R.id.buttonGetInfo);
fbLogoutButton = (Button) findViewById(R.id.buttonLogout);
fbLogoutButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
doLogout();
}
});
}
protected void doLogout() {
mAsyncRunner.logout(this, new RequestListener() {
#Override
public void onComplete(String response, Object state) {
Log.d(TAG, "Logging you out");
}
#Override
public void onIOException(IOException e, Object state) {}
#Override
public void onFileNotFoundException(FileNotFoundException e,
Object state) {}
#Override
public void onMalformedURLException(MalformedURLException e,
Object state) {}
#Override
public void onFacebookError(FacebookError e, Object state) {}
});
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
mFacebook.authorizeCallback(requestCode, resultCode, data);
}
}
I am always getting the Already logged in Toast.Am I doing something wrong?
PS. before retrieving the access_token from sharedpreferences, the app seemed to work fine, so it's not a problem with my API key or my debug key.

Try mFacebook.logout and check reponse value. If logout is successful it will be "true". Works for me.
Don't forget about Single Sign-On feature. If you will be still logged in Facebook app it won't really logout you.

Android facebook graph request

I am using android-facebook-sdk and i am trying to request profile information. But i cant get the response back. I have generated key hash with keytool and pasted it in the facebook app settings. Also i have added app ID in the code. Problem is that i cant get the profile information, or any information at all.
public class StartingPoint extends Activity {
Facebook facebook = new Facebook("actual app id");
String FILENAME = "AndroidSSO_data";
