I am building an android app in which i am using facebook android sdk to get login into facebook. The login part went smoothly but now i am hang how to display albums in gridview after getting login into facebook. When all albums would get display in grid view, then when i click on any one album it must opened with check box on top left of each image . So that when i check the check box of particular image it must be saved in device sd card and other functionality the checked images must get collage in table layout having tablerow & background color for each table row. I will attach some files so you can have idea what i want. Hoping for your positive reply for the same. So please send full source code for the same. I am trying it from last 20 days but i didnt succeed :-( Hoping for the reply soon.

You should use Facebook SDK 3.0+ for Android, and take advantage of their Request.executeAsync() method. After logging the user into the app and retrieving the Session object, you can make requests on the Graph API. Here is my method for requesting a user's albums:
/**
* Makes a request for user's photo albums from Facebook Graph API
* #param session
*/
private void fetchAlbumsFromFB(Session session) {
// callback after Graph API response with user object
Request.GraphUserCallback graphUserCallback;
graphUserCallback = new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user, Response response) {
JSONObject jsonObject = null;
if (user != null)
jsonObject = user.getInnerJSONObject();
ImageAdapter.getInstance().setPhotoAlbums(jsonObject);
}
};
// assign callback to final instance variable in inner class
final Request.GraphUserCallback finalCallback = graphUserCallback;
Request.Callback wrapperCallback = new Request.Callback() {
#Override
public void onCompleted(Response response) {
finalCallback.onCompleted(response.getGraphObjectAs(GraphUser.class), response);
}
};
// make a new async request
Bundle params = new Bundle();
params.putString("fields", "photos");
Request request = new Request(session, "me/albums", params, null, wrapperCallback);
request.executeAsync();
}
Then you can parse the JSON response like this:
/**
* Updates the array with cover photos from albums
*
* #param photosObject
*/
public void setPhotoAlbums(JSONObject photosObject) {
try {
mPhotoAlbumsArray = photosObject.getJSONArray("data");
coverPhotosArr = new String[mPhotoAlbumsArray.length()];
for (int i = 0; i < mPhotoAlbumsArray.length(); i++) {
JSONObject obj1 = mPhotoAlbumsArray.getJSONObject(i);
JSONObject obj2 = (JSONObject) obj1.get("photos");
JSONArray obj3 = obj2.getJSONArray("data");
JSONObject obj4 = obj3.getJSONObject(0);
String picture = String.valueOf(obj4.get("picture"));
coverPhotosArr[i] = picture;
}
// notify GridView's adapter that underlying data has been changed
notifyDataSetChanged();
} catch (JSONException e) {
e.printStackTrace();
}
}

On the Intent you create on the list item click listener you should add all variables you need.
In your case add
intent.putExtra("position", position);
In your DispatchTracking Activity use
int position = getIntent().getExtras().getInt("position");
Just you need to pass your HashMap Arraylist to next Activity. Like,
intent.putExtra("myList",arraylist_oper);
and in your next Activity just retrieve as
Intent intent = getIntent();
ArrayList<HashMap<String,String>> mylist = (ArrayList<HashMap<String, String>>)intent.getSerializableExtra("myList");
EDIT :
You need to pass your qrCode too next Activity
intent.putExtra("qrcodes", arraylist_oper.get(position).get("qrcode")));
Now retrieve in next activity as
String qrCode = intent.getStringExtra("qrcodes");
Now check your retrivable arraylist in your second activity using For loop.
for(int i=0; i < myList.size ; i++) {
if(qrCode.equals(myList.get(i).get("qrcode"))){
// get your data here you can get according to qrCode. Like
String density = myList.get(i).get("destiny"); // same for others
}
Facebook has recently updated their SDK to V 2.0,In effect my app must be upgraded to make calls to v2.0 or greater.
Some modifications are
*Session is replaced by Accesstoken.
So far i can login and post a video/images using GraphRequest API on their account.next step is getting user's list of albums
The doc says
/* make the API call */
new Request(
session,
"/{user-id}/albums",
null,
HttpMethod.GET,
new Request.Callback() {
public void onCompleted(Response response) {
/* handle the result */
}
}
).executeAsync();
but updated SDK doesn't has Request API neither it allows session or am i interpreting it wrong?
Has anyone found the solution yet?

The loadMoreAlbums Asynctask is run from a onScrollListener setup in the onCreate():

#Override

// FETCH THE NEXT BATCH OF FEEDS
new loadMoreAlbums().execute();
}
}

});
You can choose the relevant parts from my code, or you can use it in it's entirety (after filling a few blanks of course). Hope some of this helps.
I use this method for fetching facebook albums. It has no paging process. Working good for me.
public void getAlbums(){
GraphRequest request = GraphRequest.newMeRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
if(object!=null) {
try {
JSONObject obj = object.getJSONObject("albums");
JSONArray jArray = obj.getJSONArray("data");
for(int i =0;i<jArray.length();i++){
FbAlbumItem album = new FbAlbumItem();
JSONObject dataObj = jArray.getJSONObject(i);
album.setAlbumId(dataObj.getString("id"));
album.setAlbumName(dataObj.getString("name"));
album.setImageUrl("https://graph.facebook.com/" + dataObj.getString("cover_photo") + "/picture?type=normal"
+ "&access_token=" + AccessToken.getCurrentAccessToken().getToken());
fbAlbums.add(album);
}
lv.setAdapter(adapter);
} catch (JSONException e) {
e.printStackTrace();
}
}else
StaticFunctions.message(con,"Bir Hata Oluştu");
linlaHeaderProgress.setVisibility(View.GONE);
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "albums{id,cover_photo,name}");
request.setParameters(parameters);
request.executeAsync();
}
I used the function from Safa Gürdag and contains just one little error or deprecated call, for the date I am writing works like below. Instead of using:
album.setImageUrl("https://graph.facebook.com/" + dataObj.getString("cover_photo")
+ "/picture?type=normal" + "&access_token=" + AccessToken.getCurrentAccessToken().getToken());
I replace it with:
album.setImageUrl("https://graph.facebook.com/" + dataObj.getString("id")
+ "/picture?type=thumbnail" + "&access_token=" + AccessToken.getCurrentAccessToken().getToken());
I have one ListView,I have made a custom adapter for binding data to it,I have made an asynctask in the activity for getting data and display it into the listView,I have two different Urls for the same asyctask ,based on the condition i am using it,Thing is that when i am second time the listView doesn't remove the previous values.

Please help me for it,thank you eve-one
Try to remove the old records from your HashMap arraylist as below to remove all the data from arraylist.
After binding the data into ListView just clear your arraylist as below:
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
// Dismiss the progress dialog
if (pDialog.isShowing())
pDialog.dismiss();
msgContent = new MessageAdapter(MyMessagesActivity.this, msgList);
msgContent.notifyDataSetChanged();
lv.setAdapter(msgContent);
msgList.clear();
}
just clear your list
add mgList.clear(); in protected void onPreExecute()..
Put these lines in OnCreate() method itself,
msgContent = new MessageAdapter(MyMessagesActivity.this, msgList);
lv.setAdapter(msgContent);
Use this line in onPostExecute() of the AsynTask class,
msgContent.notifyDataSetChanged();
If this doesn't work try to add static keyword before msglist variable.
In your doInBackground() add below line before starting for loop:
msgList.clear();
You need to call msgList.clear(); before add data in to msgList arrayList. After that in onPostExecute() method just check condition while set adapter in to listview,
try {
if (msgList!= null
&& msgList.size() > 0) {
msgContent = new MessageAdapter(MyMessagesActivity.this, msgList);
lv.setAdapter(msgContent);
msgContent.notifyDataSetChanged();
} else {
Toast.makeText(YourActivityName.this,
"No Data connection", Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
e.printStackTrace();
}
Clearing the msgList is not worked for me. And use
msgList = new ArrayList>();
in doInBackground() before you adding the new content to the list. And just an info, there is no need to call notifyDataSetChanged() when you set a new instance of the adapter to a listview(And there is no problem if you called the notifyDataSetChanged).
msgContent = new MessageAdapter(MyMessagesActivity.this, msgList);
lv.setAdapter(msgContent);
I think title is self descriptive. In my application I have a log-in form. Based on request, users should be able to set their image of profile via Facebook.
So, my question is, is it possible to show gallery images of users inside application and let users to select an image from it?
I have checked Facebook SDK and goggled as well but those information that I found was base on uploading image to Facebook by Graph.
Any suggestion/comments would be appreciated.
Have you checked this answer here:
ImageView user_picture;
userpicture=(ImageView)findViewById(R.id.userpicture);
URL img_value = null;
img_value = new URL("http://graph.facebook.com/"+id+"/picture?type=large");
Bitmap mIcon1 = BitmapFactory.decodeStream(img_value.openConnection().getInputStream());
userpicture.setImageBitmap(mIcon1);
You may see this too.
Edit
I think this shall work to load albums, but the only difference is that you need an access token. This means you can fetch the album of the user only if this user is logged into Facebook. The following code has an AsyncTask called getAlbumsData. Within that look into the doInBackground.It fetches JSON and on onPostExecute,you would see it is loading the album into a listview which was already defined earlier.
Here is the (simple) sample code
private class getAlbumsData extends AsyncTask<Void, Void, Void> {
LinearLayout linlaHeaderProgress = (LinearLayout) findViewById(R.id.linlaHeaderProgress);
#Override
protected void onPreExecute() {
// SHOW THE PROGRESS BAR (SPINNER) WHILE LOADING ALBUMS
linlaHeaderProgress.setVisibility(View.VISIBLE);
}
#Override
protected Void doInBackground(Void... params) {
// CHANGE THE LOADING MORE STATUS TO PREVENT DUPLICATE CALLS FOR
// MORE DATA WHILE LOADING A BATCH
loadingMore = true;
// SET THE INITIAL URL TO GET THE FIRST LOT OF ALBUMS
URL = "https://graph.facebook.com/" + initialUserID
+ "/albums&access_token="
+ Utility.mFacebook.getAccessToken() + "?limit=10";
try {
HttpClient hc = new DefaultHttpClient();
HttpGet get = new HttpGet(URL);
HttpResponse rp = hc.execute(get);
if (rp.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
String queryAlbums = EntityUtils.toString(rp.getEntity());
JSONObject JOTemp = new JSONObject(queryAlbums);
JSONArray JAAlbums = JOTemp.getJSONArray("data");
if (JAAlbums.length() == 0) {
stopLoadingData = true;
Runnable run = new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(),
"No more Albums", Toast.LENGTH_SHORT)
.show();
}
};
Albums.this.runOnUiThread(run);
} else {
// PAGING JSONOBJECT
if (JOTemp.has("paging")) {
JSONObject JOPaging = JOTemp.getJSONObject("paging");
if (JOPaging.has("next")) {
String initialpagingURL = JOPaging
.getString("next");
String[] parts = initialpagingURL.split("limit=10");
String getLimit = parts[1];
pagingURL = "https://graph.facebook.com/"
+ initialUserID + "/albums&access_token="
+ Utility.mFacebook.getAccessToken()
+ "?limit=10" + getLimit;
} else {
stopLoadingData = true;

} else {

}
// GET THE ALBUM'S PHOTO COUNT
if (JOAlbums.has("count")) {

For more help, look into the original answer. If still you need more then there's a full working source code with explanation. Though that's a bit more confusing than the answer I referred.
How i can fetch all of user Photo albums from facebook. i tried like this with this Url https://graph.facebook.com/me/albums?access_token=xxxx
i am using this code, i was mention this permissions also "user_photos".
Bundle parameters = new Bundle();
parameters.putString("format", "json");
parameters.putString("method", "user_photos");
parameters.putString(TOKEN, facebook.getAccessToken());
JSONObject response = null;
try {
response = Util.parseJson(Album_Url);
JSONArray array = obj.optJSONArray("data");
for(int i = 0; i<array.length(); i++){
JSONObject main_obj = array.getJSONObject(i);
String album = main_obj.getString("name");
