Solution 1 :
this is happening due to your server maybe you forget to return the response there is no problem from Paytm SDK it fires callback during transaction happened …
use callback URL Post Request “https://securegw.paytm.in/theia/paytmCallback?ORDER_ID=”
create own callback URL from server request this url
within your server
try to check it from you server side it will fix
Solution 2 :
You should integrate the new SDK offering All-in-One SDK given on their developer page. Refer to the integration for the same.
Solution 3 :
Add Paytm All in One SDK dependency in Project-level Gradle file: -
allprojects {
repositories {
google()
jcenter()
maven {
url "https://artifactory.paytm.in/libs-release-local"
}
}
}
Now add another dependency in the module level Gradle file.

Problem :
I am trying to implement Paytm gateway according to this link “https://developer.paytm.com/docs/v1/android-sdk/” but in app webview opens and I am getting stuck at Paytms Processing page. below is the demo code I am using to try it. please help because Paytm is not helping. I am not missing any parameter because if I remove/change any parameter it shows an error at particular parameter.
first, I am creating an order id on the server then checksum then call Paytm service.
the same thing using the same checksum is working on PC browser but not on android.
public class MainActivity extends AppCompatActivity {
APIinterface apiInterface;
String order_id,paytmschecksum;

}
get_orderid();
}

if(details!=null){
if(details.get(0).getResponse().equalsIgnoreCase("success")){
order_id = details.get(0).getUnique_id();
Log.d("Order Id :", order_id );
get_paytmchecksum();
}
}
}
