i have a problem. I want to download file from web server database MySQL. I use JSON to parse url of the file. But when i try to download, it always return 416.
What's the problem? My code or how i store the file url in database?
My error

This is my onCreate code

In my app I am getting response from server and displayint it in listview, now what I am trying is when user click on listitem it should get position of it and need to send it to next activity, but it is not working.

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():
lv.setOnScrollListener(new OnScrollListener() {
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}
#Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
int lastInScreen = firstVisibleItem + visibleItemCount;
if ((lastInScreen == totalItemCount) && !(loadingMore)) {
if (stopLoadingData == false) {
// 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());

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");
}
} catch (JSONException e1) {
e1.printStackTrace();
} catch (FacebookError e1) {

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

if (stopLoadingData == false) {
// 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.
