问题
I am trying to get all pages url liked by user. I'm able to fetch records using below method, but paging not working. I'm getting same data every time with same before - after cursor token lead to infinite loop. Limit params also not working.
Request:
final String[] afterString = {""}; // will contain the next page cursor
final Boolean[] noData = {false}; // stop when there is no after cursor
do {
GraphRequest request = GraphRequest.newMeRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
JSONObject jsonObject = response.getJSONObject();
Log.e("cursor data", jsonObject.toString());
try {
JSONObject childObject = jsonObject.getJSONObject("likes");
JSONArray jsonArray = childObject.getJSONArray("data");
Log.e("cursor data", jsonArray.toString());
// your code
if (!childObject.isNull("paging")) {
JSONObject paging = childObject.getJSONObject("paging");
JSONObject cursors = paging.getJSONObject("cursors");
if (!cursors.isNull("after"))
afterString[0] = cursors.getString("after");
else
noData[0] = true;
} else
noData[0] = true;
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "likes{link}");
parameters.putString("after", afterString[0]);
parameters.putString("limit", "20");
request.setParameters(parameters);
request.executeAndWait();
}
while (!noData[0] == true);
Response:
{
"likes": {
"data": [
{
"link": "https:\/\/www.facebook.com\/hackingworld27\/",
"id": "206659129366770"
},
{
"link": "https:\/\/www.facebook.com\/getBksy\/",

},
{
"link": "https:\/\/www.facebook.com\/subhamfashion\/",
"id": "1454168668186632"
},
],
"paging": {
"cursors": {
"before": "MjA2NjU5MTI5MzY2Nzcw",
"after": "MTEyMTgwMjU1NDg2MTI0"
}
}
},
"id": "858224610968939"
}
Above response is sample response. I tried to send request by user id who has liked so many pages, but getting same 25 records maximum every time.
