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.

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.....**

Android Studio Client-Server message struggle

I have a server app in android studio and a client app.
Although the client is able to connect to server I can't seem to pass a message through to the client. I am very new to the networking concept so a little help would be much appreciated.
My MainActivity Class:

You are trying to do networking on the main thread, which will block any UI actions,

How to store EditText data when sent [duplicate]

This question already has an answer here:
What is the simplest way in Android to keep an objects value after every app run?

Closed 7 years ago.
I have an android chat application that sends messages from client to server but I am looking for a way to store the send messages in some way, other than being displayed in the list.
Here is part of my application;
public class AndroidChatApplicationActivity extends Activity {

// msgView.smoothScrollToPosition(msgList.getCount() - 1);

Could anyone suggest a method of storing the messages other than displaying them in a list?

You can try storing them in SharedPreferences. By what I gather, you want store the input so that you can later look at then in a different activity. Have a look at SharedPreferences here http://developer.android.com/reference/android/content/SharedPreferences.html

How to view the Intents a BroadcastReceiver is receiving?

I have an infinite loop somewhere in my code, indicative of my group messaging BroadcastReceiver continually accepting only the first message in the database, over and over again, until I stop running the application. Note that the repeating of the message only occurs in the client app and not in the server database.
Is there way to trace what intent the BroadcastReceiver is receiving? ie. be able to view the intents the BroadcastReceiver is acting on to locate the source of these actions?
My code for both sending and receiving a group message if it helps: (BroadcastReceiver is near the bottom)

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);
