Paytm Sdk Version 2 - Paytm integration in Android App throwing OOPS error in doInBackground

I am integrating Paytm SDK in my Android Application. I have to POST ORDER ID and callbackurl along with other paytm credentials. All values are passing correctly. But OOPS error is displaying.
Code

My Android Studio Monitor output of

Which means the two parameter values are posting successfully and i can be able to GET them also. But the following error is displaying

I just used the second code to test the trasaction. But i have to use the first posted code because i have to post the ORDERID and CALLBACKURL from android application to server . Any help would be appreciable.

**Here is the solution for all :**
Be sure to send equal number of parameters to your server (For checksum generator) And then to paytm server for payment.
**For example:**
If you are sending 6 params for checksum generator, then send these 6 same parameters including Checksum to Paytm...
It will resolve your problem.
**CODE EXAMPLE :**
**Generate checksum.php**
$paramList = array();
$paramList["MID"] = 'Provided by Paytm'; //Provided by Paytm
$paramList["ORDER_ID"] = 'hIquwhzvzTG7gvT'; //unique OrderId for every request
$paramList["CUST_ID"] = 'CUST0001453'; // unique customer identifier
$paramList["INDUSTRY_TYPE_ID"] = 'Retail'; //Provided by Paytm
$paramList["CHANNEL_ID"] = 'WAP'; //Provided by Paytm
$paramList["TXN_AMOUNT"] = '10.00'; // transaction amount
$paramList["WEBSITE"] = 'APP_STAGING';//Provided by Paytm
$paramList["CALLBACK_URL"] = 'https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp';
**Android Activity.java**
paramMap.put("MID" , "#########");
paramMap.put( "ORDER_ID" , "hIquwhzvzTG7gvT");
paramMap.put( "CUST_ID" , "CUST0001453");
paramMap.put( "CHANNEL_ID" , "WAP");
paramMap.put( "TXN_AMOUNT" , "10.00");
paramMap.put( "WEBSITE" , "APP_STAGING");
paramMap.put( "CALLBACK_URL" , "https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp");
paramMap.put( "CHECKSUMHASH" , "dR5OtEkuNkgamHTZDCHmF+CF3j9RdG1520mlHEb85oSZP1CaxVUsRY2sYric90HLm/vElaPZKoQ7b5/SyFpi3oBWXf2BQNy+r6iiBwg4AH4=");
paramMap.put("INDUSTRY_TYPE_ID" , "Retail");
**NOTE : Please keep in mind to send paytm server exact parameters plus one checksum.....**

Asyntask not executing onPostExecute()

This is my Asyntask code which is not firing the onPostExecute() Any one has any idea why this might be happening???
EDIT: The Asyntask is called this way
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
callbackManager = CallbackManager.Factory.create();
setContentView(R.layout.activity_main);
.
.
textView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), SignUp.class);
startActivity(intent);
}
});
textView2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), Feedback.class);
startActivity(intent);
}
});
fbLoginButton = (LoginButton) findViewById(R.id.login_button);
fbLoginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
token=loginResult.getAccessToken().getToken().toString();
Log.v("tag", "Token:\n" + token);
try {
get_profile();
}catch (Exception ex) {
String error = ex.getMessage();
}
}
#Override
public void onCancel() {
Toast.makeText(MainActivity.this, "Login cancelled by user!", Toast.LENGTH_LONG).show();
System.out.println("Facebook Login failed!!");
}
#Override
public void onError(FacebookException e) {
Toast.makeText(MainActivity.this, "Login unsuccessful!", Toast.LENGTH_LONG).show();
System.out.println("Facebook Login failed!!");
}
});
}
The get_profile(); method is defined like this
//Method to get profile details
public void get_profile() throws UnsupportedEncodingException {
try {
// Calling async task to get json
new FetchOperation().execute();
} catch (Exception e) {
e.printStackTrace();
}
}
This is inside the Main class too
//Asynctask to get Getting fb profile details
private class FetchOperation extends AsyncTask<Void, Void, String> {
String fb_token;
#Override
protected void onPreExecute() {
super.onPreExecute();
// Get user defined values
fb_token = token;
}
#Override
protected String doInBackground(Void... params) {
String response = "";
String Urls = "https://graph.facebook.com/me?access_token=";
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(Urls +token);
HttpEntity httpEntity = null;
HttpResponse httpResponse = null;
try {
httpResponse = httpclient.execute(httpget);
} catch (ClientProtocolException e) {
e.printStackTrace();
Log.v("Response", "Hi From e1 : " + e.toString());
} catch (IOException e) {
e.printStackTrace();
}
try {
httpEntity = httpResponse.getEntity();
response = EntityUtils.toString(httpEntity);
Log.v("Response", "Hi From 2 : "+response.toString());
return response;
} catch (IOException e) {
e.printStackTrace();
Log.v("Response", "Hi From e2 : " + e.toString());
}
return null;
}
#Override
protected void onPostExecute(String jsonStr) {
super.onPostExecute(jsonStr);
Log.v("tag", "Result:" + jsonStr);
if (jsonStr != null) {
try{
JSONObject jsonObj = new JSONObject(jsonStr);
String email = jsonObj.getString("email");
String firstName = jsonObj.getString("first_name");
String lastName = jsonObj.getString("last_name");
String gender = jsonObj.getString("gender");
String country = jsonObj.getString("locale");
id = jsonObj.getString("id");
user = firstName.concat(" ");
user = user.concat(lastName);
image = "http://graph.facebook.com/" + id + "/picture?type=large";
Log.v("Fb name", "Bla bla Name : " + user);
new UploadOperation().execute();
}
catch (JSONException e) {
e.printStackTrace();
}
}
else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
}
}
This is the last lines of the logcat
06-29 14:30:49.927 2091-2091/com.example.kmi_dev.fbloginsample V/tag﹕ Token:
CA****************************************************************xr

06-29 14:31:23.827 2091-2098/com.example.kmi_dev.fbloginsample W/art﹕ Suspending all threads took: 10ms
I intend to fire another asyntask which will then save the data fetched by this asyntask into the database.

Make these changes, it will work -
private class FetchOperation extends AsyncTask<Void, Void, String>
change to - private class FetchOperation extends AsyncTask<Void, String, String> , because, you are trying to return String.
response = EntityUtils.toString(httpEntity);
change to - response = EntityUtils.toString(httpEntity).toString();
at the next line of this you have actually done it.
At the very end of doInBackground method where return null;
change to - return response;
4.No need to call super in onPostExecute()
5.Inside onPostExecute() check jsonStr is null or not and do whatever you want to do if null and if contains json data.

Your JSONObject does not contain a JSONString "email", so it is falling over at line
String email = jsonObj.getString("email");
and going straight to catch block.

How to get friends info that requires permission like B'day using facebook graph api

I'm having android Button for Login.
below is the onclick listener of that button.
btnLoginFB.setOnClickListener(new View.OnClickListener() {
#
Override
public void onClick(View v) {
Session s = new Session(Startup.this);
Session.setActiveSession(s);
Session.OpenRequest request = new Session.OpenRequest(Startup.this);
List < String > permissions = new ArrayList < String > ();
permissions.add("friends_birthday");
permissions.add("friends_location");
request.setPermissions(permissions);
request.setCallback(new Session.StatusCallback() {
#
Override
public void call(Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
Request.newMyFriendsRequest(Session.getActiveSession(), new Request.GraphUserListCallback() {
#
Override
public void onCompleted(List < GraphUser > users, Response response) {
if (users != null) {
for (int i = 0; i < users.size(); i++) {
String frndLoc = "empty";
try {
users.get(i).getLocation().getProperty("name");
frndLoc = "" + users.get(i).getLocation().getProperty("name");
} catch (Exception e) {}
Toast.makeText(Startup.this, users.get(i).getBirthday() + " - " +
users.get(i).getName() + "\n" +
frndLoc, Toast.LENGTH_LONG).show();
}
}
}
}).executeAsync();
} // end of if (session.isOpened())
} // end of call
});
s.openForRead(request);
}
});
The problem is I'm getting null for both B'day and Location of friend.

Request friendRequest = Request.newMyFriendsRequest(activeSession, new GraphUserListCallback() {
#Override
public void onCompleted(final List<GraphUser> users, Response response) {
ArrayList<String> o = new ArrayList<String>();
for (GraphUser u : users) {
o.add(u.getInnerJSONObject().toString());
}
getSherlockActivity().startService(
new Intent(getSherlockActivity(), InsertInDBService.class).putExtra("fbdata", o));
}
}
});
Parse the reponse
int count = users.size();
for (int i = 0; i < count; i++) {
String name = "", id = "", photoUrl = "";
String birthday = "", location = "";
String website = "";
JSONObject o = null;
try {
o = new JSONObject(users.get(i));
} catch (JSONException e) {
}
try {
id = o.getString("id");
name = o.getString("name");
photoUrl = o.getJSONObject("picture").getJSONObject("data").getString("url");
} catch (JSONException e) {
e.printStackTrace();
dbFacebookMain.deleteFACEBOOK();
}
try {
location = o.getJSONObject("location").getString("name");
} catch (JSONException e) {
}
try {
birthday = o.getString("birthday");
} catch (JSONException e) {
}
try {
website = o.getString("website");
} catch (JSONException e) {
}

try another way to integerate twitter in your app
Using auth & webview(Twitter4j library)
http://davidcrowley.me/?p=410
http://www.mokasocial.com/2011/07/writing-an-android-twitter-client-with-image-upload-using-twitter4j/
code(url open in web view)
twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(TwitterConstants.CONSUMER_KEY,
TwitterConstants.CONSUMER_SECRET);
RequestToken requestToken = null;
try {
requestToken = twitter.getOAuthRequestToken();
System.out.println("requesttoken"+requestToken);
} catch (TwitterException e) {
e.printStackTrace();
}
twitterUrl = requestToken.getAuthorizationURL();
ConfigurationBuilder builder = new ConfigurationBuilder();
builder.setOAuthAccessToken(TwitterConstants.ACCESS_TOKEN);
builder.setOAuthAccessTokenSecret(TwitterConstants.ACCESS_TOKEN_SECRET);
builder.setOAuthConsumerKey(TwitterConstants.CONSUMER_KEY);
builder.setOAuthConsumerSecret(TwitterConstants.CONSUMER_SECRET);
OAuthAuthorization auth = new OAuthAuthorization(builder.build());
twitter = new TwitterFactory().getInstance(auth);
try {
twitter.updateStatus("Hello World!");
} catch (TwitterException e) {
System.err.println("Error occurred while updating the status!");
}
2. On Button Click(Without auth)
String message="";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse("http://twitter.com/?status=" + Uri.encode(message)));
startActivity(i);
