PayUmoney seamless Integration

experts
can you help me in seemless integration with PayUmoney payment Gateway in android
also if you have any sample of seemless integration please share
i have tried like this but showing me error of Marchentkey and salt is incorrect but i copied both from my account
below is code detail

Linkedin returns "No value for accessTokenValue" and "access toke is not set". It was working like last month but suddenly it does not work and I could not find anything wrong with the code. After much digging on Google, I am still unable to find a solution. Or am I using the v1 api which I should not? Any help will be greatly appreciated.

This is because the token generated by Linkedin SDK can not be verified by backend. The best solution is to open a webview and use Linkedin web apis- Step 1 - Create a new Class LinkedinActivity

interface LinkedinData {
void linkedCancel();
void LinkedinSuccess(String Token);
}
}
Step 2 - Call LinkdinActivity.java class using the following code
new LinkedinActivity(this).showLinkedin();
You can call the above code on the click of a button. Example
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
new LinkedinActivity(this).showLinkedin();
}
});
Here is linkedin_activity.xml

How to return Object which is inside anonymous inner class?

I've created this code to access user from my database for Login purpose. I can access the object 'st' when I'm inside OnResponse method but when I try to return return the object, it gives me null. Also when I try to access this st object before returning, it gives NullPointerException. What is the exact problem?
public class ServerRequests {
ProgressDialog progressDialog;
public static user_Student st;
public static final int CONNECTION_TIMEOUT = 1000 * 15;
public static final String SERVER_ADDRESS = "http://prem-pc:8989/";
Context ct;
public ServerRequests(Context context) {
ct = context;
progressDialog = new ProgressDialog(context);
progressDialog.setCancelable(false);
progressDialog.setTitle("Processing");
progressDialog.setMessage("Please Wait....");
}
public ServerRequests() {
}
public user_Student fetchUserDataInBackground(user_Student user) {
progressDialog.show();
Toast.makeText(ct, "Data in background: ", Toast.LENGTH_SHORT).show();
user_Student ust = doInBackground(user);
progressDialog.dismiss();
return ust;
}
public user_Student doInBackground(user_Student user) {
String URL = SERVER_ADDRESS + "connect.php?prn=" + user.prn + "&password=" + user.password;
RequestQueue req = Volley.newRequestQueue(ct);
Toast.makeText(ct, "Do in Background", Toast.LENGTH_SHORT).show();
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.GET, URL, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject jObject) {
try {
// Parsing json object response
// response will be a json object
if (jObject.length() == 0) {
st = null;
Toast.makeText(ct, "Null JSON Object", Toast.LENGTH_SHORT).show();
} else {
String prn = jObject.getString("prn");
String fname = jObject.getString("fname");
String mname = jObject.getString("mname");
String lname = jObject.getString("lname");
String clas = jObject.getString("clas");
String dept = jObject.getString("dept");
String batch = jObject.getString("batch");
String scontact = jObject.getString("scontact");
String pcontact = jObject.getString("pcontact");
String email = jObject.getString("email");
String password = jObject.getString("password");
String dob = jObject.getString("dob");
st = new user_Student(prn, fname, mname, lname, clas, dept, batch, scontact, pcontact, email, password, dob);
Toast.makeText(ct, "JSON Object:" + st.fname, Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(ct, "Error: " + e.getMessage(), Toast.LENGTH_LONG).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(ct, error.getMessage(), Toast.LENGTH_SHORT).show(); // hide the progress dialog
}
});
req.add(jsonObjReq);
//Toast.makeText(ct,"DO in back End"+st.fname,Toast.LENGTH_SHORT).show();
return st;
}
}

You can't return from anonymous inner classes, but you could create a method inside ServerRequests that takes a user_Student as a parameter and call that method from within onResponse. This method could then do whatever you need.

You must use AsyncTask to do funtion doInBackground(user_Student user)

login issue using twitter api in android

what is the procedure to login throw twitter api1.1.
i have used old api that will show me twitter connection failed because of api 1 is deprecated.
private final TwDialogListener mTwLoginDialogListener = new TwDialogListener()
{
public void onComplete(String value)
{
getTwitterDetail();
}
public void onError(String value) {
Toast.makeText(LoginActivity.this, "Twitter connection failed", Toast.LENGTH_LONG).show();
}
};
LOG
{"errors": [{"message": "The Twitter REST API v1 is no longer active.
Please migrate to API v1.1. https://dev.twitter.com/docs/api/1.1/overview.", "code": 68}]}

As you see from error log API v.1 is no longer active and everybody must migrate to v1.1. In API v1.1. you must log in via OAUTH to get connected. So you also have to register your app on dev.twitter.com.
You can find below example here

Upgrage Twitter login to use Twitter API 1.1

I use this sample to login Twitter, post status and photo. I used it for a long time. Now Twitter requires upgrading from Twitter API 1.0 to Twitter API 1.1. What do I have to do to upgrade it? I tried to replace the old lib with this lib and there is no problem so far but I'm scared of I didn't do the change completely.
