public class PayPal extends AppCompatActivity {
private static final int PAYPAL_REQUEST_CODE = 7171;
private static PayPalConfiguration config = new PayPalConfiguration()
.environment(PayPalConfiguration.ENVIRONMENT_SANDBOX)
.clientId(Config.PAYPAL_CLIENT_ID);
Button btnPayNow;
EditText edtAmount;
String amount = "";
@Override
protected void onDestroy() {
stopService(new Intent(this,PayPalService.class));
super.onDestroy();}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pay_pal);
Intent intent = new Intent(this,PayPalService.class);
intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION,config);
startService(intent);
btnPayNow = findViewById(R.id.btnPayNow);
edtAmount = findViewById(R.id.edtAmount);
btnPayNow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
processPayment();

amount = edtAmount.getText().toString();
PayPalPayment payPalPayment = new PayPalPayment(new BigDecimal(String.valueOf(amount)),"RM",
"Registration Fee",PayPalPayment.PAYMENT_INTENT_SALE);
Intent intent = new Intent(this, PaymentActivity.class);
intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION,config);
