I am trying to add Upi payment to android app to pay the bill automatically for coffee ordering app(digital payment) . I searched in google but it didn't work. So anyone can explain me the steps in detail.
Create a button which will trigger the intent to open the new activity called upi. Follow these steps carefully 1. To open the upi activity create a activity named bill.xml and bill.java
bill.xml
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="188dp"
android:layout_marginBottom="28dp"
android:text="Pay"
android:onClick="pay"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.955"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.726" />
</androidx.constraintlayout.widget.ConstraintLayout>
bill.java
package com.example.smart_park;
import com.example.smart_park.Starttimer;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class bill extends AppCompatActivity {
double total_price=89.78;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_bill);
}
public void pay(View view){ //this will be triggered when button is clicked
Intent myIntent = new Intent(getApplicationContext(),upi.class);
//ADD the data into bundle and send
Bundle bundle = new Bundle(); //create a bundle and send it to activity called upi class.
bundle.putString("stuffs", Double.toString(total_price));
myIntent.putExtras(bundle);
startActivity(myIntent); //for more details refer stackoverflow how to send data from one activity to other
}
}
Now create upi activity FILE-->NEW-->ACTIVITY-->Empty Activity-->Activity name:upi --> click ok
Now add these to upi.xml
upi.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"

<EditText

<EditText

android:layout_below="@+id/amount_et"

android:text="1234@ybl"/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Name"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="20dp"
android:id="@+id/name"
android:layout_below="@+id/upi_id"
android:focusable="false"
android:text="Rakshit"/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Note"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="20dp"
android:id="@+id/note"
android:focusable="false"
android:layout_below="@+id/name"
android:text="Fees charged"/>
<Button
android:layout_width="100dp"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
android:textColor="#fff"
android:id="@+id/send"
android:layout_below="@+id/note"
android:layout_marginTop="20dp"
android:layout_centerHorizontal="true"
android:text="send by upi"/>
</RelativeLayout>
Replace 1234@ybl with recievers upi id xxxxxx@ybl or any other upi id

YOU CAN ADD YOUR LOGIC HERE WHAT TO DO IF THE PAYMENT IS SUCCESSFUL
if (status.equals("success")) {

Toast.makeText(upi.this, "Transaction successful.", Toast.LENGTH_SHORT).show(); //TOAST THAT PAYMENT IS SUCCESSFUL
// Log.d("UPI", "responseStr: "+approvalRefNo);
Toast.makeText(this, "YOUR ORDER HAS BEEN PLACED\n THANK YOU AND ORDER AGAIN", Toast.LENGTH_LONG).show();
}
HURRAY DONE WITH THE PAYMENT
NOTE: ONLY FOR GOOGLE PAY IT IS WORKING
FOR PHONEPE AND OTHER EVEN IF THE PAYMENT IS SUCCESSFUL IT IS TELLING PAYMENT FAILED.
