   MoamalatPayment(...)
   
   // NEW (Recommended)
   MoamalatPaymentUnified(...)  // Auto-selects best method
   

2. Amount Handling: No changes needed - dirham strings work everywhere

   amount: "1000"  // Still correct for all widgets
   amount: CurrencyConverter.dinarToDirham(1.0)  // Still correct
   

3. Android Setup: Add SDK dependencies for optimal performance

   dependencies {
       implementation 'com.github.payskyCompany:NUMO-PayButton-SDK-android:1.0.12'
   }
   

4. Existing Code: All existing MoamalatPayment usage continues to work
