Payment app content provider

This documentation describes usage of Content provider of Payment app.

Content provider is available from version 3.35.0 of the Payment app

Steps to use the Content provider

1. Add following line to AndroidManifest.xml of your application:

 <uses-permission android:name="com.pc3k.paymentapp.PAYMENT_APP_DATA" />

2. Use content resolver to get data you want. At the moment, the provider supports these URIs:

   • content://com.pc3k.paymentapp.PaymentAppContentProvider/currentTid - returns currently selected TID
   • content://com.pc3k.paymentapp.PaymentAppContentProvider/availableTids - returns all available TIDs (if multi merchant is supported)

   Example of reading current TID (in Kotlin):

   try {  
       val uri = Uri.parse("content://com.pc3k.paymentapp.PaymentAppContentProvider/currentTid")  
       val cursor = activity.contentResolver.query(  
           uri, null, null, null, null, null  )  
       if(cursor != null) {  
           val res = cursor.moveToFirst()  
           if(!res) {  
               //TODO cursor is empty
           }  
           val tid = cursor.getString(0)
           cursor.close()  
       } else {  
           //TODO 
       } 
   } catch (e: Exception) {  
       //TODO
   }
   

   Example of reading available TIDs (in Kotlin):

   try {  
       val uri = Uri.parse("content://com.pc3k.paymentapp.PaymentAppContentProvider/availableTids")  
       val cursor = activity.contentResolver.query(  
           uri, null, null, null, null, null  )  
       if(cursor != null) {  
           val tids = mutableListOf<String>()
           while(cursor.moveToNext()) {
   	        tids.add(cursor.getString(0))
           }
           cursor.close()  
       } else {  
           //TODO 
       } 
   } catch (e: Exception) {  
       //TODO
   }
