I have a problem with accessing the graph API through my android application that retrieves a user's friends as JSONObject, extracts their names and displays them on the screen. It is supposed to be a simple and straightforward task but apparently it is not. When I run my application on Android Nexus I, I login to Facebook, then I am asked I click "Allow" button to grant permissions and I am redirected to a blank page. I am expect to see the name of my friends but it does not happen. Could some one assist me.
public class Login extends Activity
{
Facebook mFacebook = new Facebook("201509899926116");
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(mFacebook);
String FILENAME = "AndroidSSO_data";
private SharedPreferences mPrefs;
View linearLayout;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
linearLayout = findViewById(R.id.main_layout);
/* Get existing access_token if any */
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if(access_token != null)
{
mFacebook.setAccessToken(access_token);
}
if(expires != 0)
{
mFacebook.setAccessExpires(expires);
}
/* Only call authorize if the access_token has expired. */
if(!mFacebook.isSessionValid())
{
mFacebook.authorize(this, new String[] {"user_birthday","email",
"user_relationships","user_religion_politics","user_hometown",
"user_location","user_relationship_details","user_education_history",

TextView tv = new TextView(Login.this);
tv.setText(n);
((LinearLayout) linearLayout).addView(tv);
}
}
catch (JSONException e)
{
Log.w("Facebook-Example", "JSON Error in response");
}
}
}
}
I think i might've found the issue.. According to the documentation on onComplet;
/**
* Called when a request completes with the given response.
*
* Executed by a background thread: do not update the UI in this method.
*/
And you are trying to update your UI, so addViews don't actually get reflected on the UI thread.. You should create a method in your activity that you can call from onComplete with runOnUIThread.. Something like this;
runOnUiThread(new Runnable() {
public void run() {
inserFacebookNames(facebookContactNames);
}
});
Let me know if this actually fixes it.. I'm curious if that was the reason..

Anybody has working sample code for Facebook login in Android using the code snippet mentioned in Facebook developer site ??I couldn't understand it properly.I want to get the name and profile picture of logged in user.I want my app to display the name and profile picture as long as the session is active and need to modify the details if user changed any.
Currently what i do is,saving access token and name in shared preferences on first login and saving the image in sd card and checking access token value during each app launch.If access token value is not null,then i display the name from shared preferences and profile picture from sd card.I know that this is not the right way to do this.Somebody please help me with this.
You can this https://github.com/sromku/android-simple-facebook library it is pretty well defined and can get details of methods by searching simle facebook android on google. Do whatever you want to do with facebook with this library....happy coding
Try this code

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;

super.onCreate(savedInstanceState);

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

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

Please anyone tell me how can I avoid this error...
Below is my code and I integrated the facebook in my app. I am trying to make the user to be able to post an image on his wall after logging in. But I have been failing to make it for three days. Have seen few posts like this but I don't get any data(just it results in empty data data[]). I am even facing trouble with maintaining sessions too. Can some one please post working code or at least some sources where I can post image on facebook wall? Hope my below code is clear and my explanation is clear on what I have tried with the code below.
Activity's onCreate():-
public class FacebookActivity extends BaseActivity {
private static String APP_ID = "1303786178";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fb_screen);
btnFbLogin = (Button) findViewById(R.id.fbloginbtn);
btnFbLogout = (Button) findViewById(R.id.fblogoutbtn);
btnPostToWall = (Button) findViewById(R.id.fbpostbtn);
msget = (EditText)findViewById(R.id.fbmsget);
mAsyncRunner = new AsyncFacebookRunner(facebook);
mHandler = new Handler();
String passedpath = getIntent().getStringExtra("imagepath").toString();
imageuri = Uri.parse(passedpath);
/**
* Login button Click event
* */
btnFbLogin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("Image Button", "button Clicked");
loginToFacebook();
}
});
btnFbLogout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("Image Button", "button Clicked");
logoutFromFacebook();
}
});
/**
* Posting to Facebook Wall
* */
btnPostToWall.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//postToWall(imageuri);
getAlbumId();
}
});
}
Posting on Wall includes two functions in my code one is getAlbumId() and the other is posttowall() which will be called from getAlbumId():-
public void getAlbumId()
{
dialog = ProgressDialog.show(FacebookActivity.this, "","Please Wait...", true, true);
//String wallAlbumID = null;
mAsyncRunner.request("me/albums", new BaseRequestListener(){
#Override
public void onComplete(String response, Object state) {
// TODO Auto-generated method stub
try{
Log.d("response in album"," "+response);
JSONObject json = Util.parseJson(response);
JSONArray albums = json.getJSONArray("data");
for (int i =0; i < albums.length(); i++) {
JSONObject album = albums.getJSONObject(i);
if (album.getString("type").equalsIgnoreCase("wall")) {
final String wallAlbumID = album.getString("id");
globalalbid = wallAlbumID;
Log.d("JSON", wallAlbumID);
break;
}
}
dialog.dismiss();
mHandler.post(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), "id: " + globalalbid, Toast.LENGTH_LONG).show();
if(globalalbid != "")
postToWall(imageuri, globalalbid);
}
});
}catch (JSONException e) {
e.printStackTrace();
}
}
});
}
function to post on wall:
public void postToWall(Uri locuri, String wallid) {
if (facebook.isSessionValid()) {
Util.showAlert(this, "Warning", "You must first log in.");
} else {
dialog = ProgressDialog.show(FacebookActivity.this, "","Please Wait...", true, true);
// post on user's wall.
Uri photoUri = locuri;
if (photoUri != null) {
Bundle params = new Bundle();
try {
params.putByteArray("photo",
Utility.scaleImage(getApplicationContext(), photoUri));
} catch (IOException e) {
e.printStackTrace();
}
String imagecaption = msget.getText().toString();
if(imagecaption != "")
params.putString("caption", imagecaption);
mAsyncRunner.request(wallid+"/photos", params, "POST", new PhotoUploadListener(), null);
} else {
Toast.makeText(getApplicationContext(),
"Error from the pic", Toast.LENGTH_SHORT)
.show();
}
}
}
}
I always get album id empty. Is there anything wrong in the way that I try to get album id. Because I have seen on some posts those who try to access album id and then posting the image on album. They seem to be keeping wall as common findout in the album name. If it is so, some new ones contain timeline photos name, then how can we findout the album id. Please suggest.
Note: I want the image to be visible on to the wall not to only album.
Instead of uploading the photo to the user's album, post the image to /me/feed instead. Make sure you are asking the user for the publish_stream permission. This will upload the photo straight to the user's wall instead of going to an album.
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");

Error says you don't have required access token. try to print facebook.getaccesstoken() and see if you have valid token.with this token you can try in browser to see if you get profile information
I have been struggling with android and the Facebook's graph API and I'm sure this is a piece of cake for intermediate programmers. What I want is a very simple Android application that logs in a user to Facebook, get the users consent to access information and finally to seamlessly query the graph API to get the users friends. I mention the work seamless because I have seen many sample applications that require the user to push a "get friends" button but I do not want that. I wish to extract the users friends without requiring him to push anything.
I have pasted the code below. I am able to to log-in and grant permission to my application. Next, I expect it to display my friends but it just directs me to a blank page. The problem might be that I am accessing the graph API in the wrong place because the Logcat does not contain the messages I print before and after the request. Could you please help me.
