¿Cómo integrar TEST PayU Payment Gateway en la aplicación android?

Creo que su código está bien, también estoy haciendo lo mismo y llegué a saber de payu que prueba merchant_key y la sal no está trabajando actualmente. Pruebe el modo de producción.

Si desea cargar datos desde el servidor (postUrl):

  post_Data = "hash="+PayMentGateWay.this.hash+"&key="+merchant_key+"&txnid="+PayMentGateWay.this.params.get("txnid")+"&amount="+PayMentGateWay.this.params.get("amount")+ "&productinfo="+PayMentGateWay.this.params.get("productinfo")+"&firstname="+PayMentGateWay.this.params.get("firstname")+ "&email="+PayMentGateWay.this.params.get("email")+"&phone="+PayMentGateWay.this.params.get("phone")+ "&surl="+PayMentGateWay.this.params.get("surl")+"&furl="+ PayMentGateWay.this.params.get("furl")+ "&service_provider="+ "payu_paisa"; webView.postUrl("https://secure.payu.in/_payment", EncodingUtils.getBytes(post_Data, "base64")); 

Espero que esta ayuda.

Hola chicos he implementado con éxito Gateway de pago

No han activado la cuenta de prueba.

"Lo sentimos, se ha producido algún problema" este error aparece cuando no tiene una clave de Comerciante válida y una clave de Sal. En este caso, debe ponerse en contacto con el equipo de soporte de atención al cliente de PayU Money para obtener la clave Merchant y Salt válida. Espero que esto te ayudará.

Yo estaba enfrentando el mismo problema y estoy alimentando con esta integración.

Pero después de ponerse en contacto con el equipo de deportes payumoney.com, me dijeron que el kit de integración que aparece en el kit de descarga no está activo, es decir, la clave (JBZaLc) y la sal (GQs7yium) es sólo un dummy de datos. Así que tenemos que enviar los detalles de su empresa, incluyendo los datos bancarios, a continuación, verifican los detalles de su empresa, a continuación, nos proporcionará el nuevo kit de integración. Con ese kit podemos hacer las pruebas.

Se produjo debido a un error técnico en PayUMoney. Es necesario ponerse en contacto con el equipo de soporte técnico para emitir el nuevo ID y clave del comerciante.

Descargue el proyecto de demostración desde aquí github project link

y cambio

 int env = PayuConstants.STAGING_ENV; 

Esto hará para el modo de prueba
