You can try DeepLinking UPI supported application. This way you can make a payment via any UPI supported application (BHIM, Phonepe, Paytm and all bank UPI apps)

Code for deeplinking is as follow:

Uri uri = Uri.parse("upi://pay?pa=8866616231@upi&pn=Aayushi%20Shah&tn=Test%20for%20Deeplinking&am=1&cu=INR&url=https://mystar.co"); // missing 'http://' will cause crashed
Log.d(TAG, "onClick: uri: "+uri);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivityForResult(intent,1);

Almost all UPI application are successfully able to make the payment. The problem with this is, not all application are returning whether the transaction was a success or not.

I am finding a solution where i can force to open Only BHIM and not any other app, as BHIM is giving proper response back.

You need to implement UPI SDK in your application. Some UPI enabled banks are allowed to act PSP(Payment service Provider) like Yes Bank, RBL, ICICI Bank, Axis Bank.

You have to partner with that bank and they will provide you SDK. Once you get SDK, it is easy like plug n play.

You can also readout about upi from

You can try DeepLinking UPI to start BHIM from your app.

Code for deeplinking is as follow:

Uri uri = Uri.parse("upi://pay?pa=payee_address&pn=payee_name&tn=transaction_name&am=1&cu=INR&url=url");//url with http or https
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
//Now magic starts here
intent.setClassName("in.org.npci.upiapp","in.org.npci.upiapp.HomeActivity");
startActivityForResult(intent,1);

You can open any specific application using its packageName and ClassName.

Now you can collect payment using only BHIM. You can get proper response using BHIM.
