If you want to inquire about a payment instance already made in the RDCPass application, follow the steps below.

1. Add the intent-filter (Activity) in your project's AndroidManifest.xml file:

<action android:name="android.intent.action.ANSWER" />

In addition to the intent-filter for creating the payment intention, your project should look like this:

android
Copiar

<intent-filter> 
	<action android:name="android.intent.action.SEND" /> 
	<action android:name="android.intent.action.ANSWER" /> 
	<category android:name="android.intent.category.DEFAULT" /> 
	<data android:mimeType="text/*" /> 
</intent-filter>

2. Implement again the "shareRDCPass" function used to create a payment intention, but change the String intent to the value Intent.ACTION_ANSWER, which corresponds to the intention of querying for a payment.

The String total value, on the other hand, can be empty (String total = "").

android
Copiar

public void shareRDCPass(String total, String intent) { 
	try { 
		Intent sharingIntent = new Intent(intent); 
		sharingIntent.setClassName("redelcom.cl.rdcpass", "redelcom.cl.rdcpass.MainActivity"); 
		sharingIntent.putExtra("packageName", getPackageName()); 
		sharingIntent.putExtra("className", getClass().toString().split(" ")[1]); 
		sharingIntent.putExtra("userTransactionId", "DEMO1234"); 
		startActivity(sharingIntent); 
	} catch (Exception e) { 
		e.printStackTrace(); 
	} 
}

3. To receive the response from RDCPass, you should also include the following code block:

android
Copiar
try{ 
	Intent intent = getIntent(); 
	String action = intent.getAction(); 
	String payload = new JSONObject(intent.getStringExtra("payload")); 
	String userTransactionId= new JSONObject(intent.getStringExtra("userTransactionId")); 
	if (Intent.ACTION_ANSWER.equals(action)) { 
		// Define what to do with the received data “payload” 
	} 
} catch (Exception e) { 
	e.printStackTrace(); 
} 

The structure of the response for the payment query intention will be the same as that provided during the creation of a payment intention. You can check it out in the annex: response examples.
