Android Google Play In APP Billing Library v:5.1.0

UCDEMİR YAZILIM : As your service, Developing Future

You can test this library, with real device: Android Example App

This Library designed as Google guide

• Library is supported for "INAPP"
• Subscription will be supported later!
• Library use Roomdb for your products
• Library use Shared dependency (App module ). Your app will be less sized and no multidex needed
• Library checks your products status on every time app starts.
• Every product bought by client need to be " Acknowledged" in SUCCES State. Library is making this for you!

Implementation

Add below commands inside application tag in manifest

      android:fullBackupContent="false"
      android:allowBackup="false"
      tools:replace="android:allowBackup"

Add permission to manifest

<uses-permission android:name="com.android.vending.BILLING"/>

Add this In Project module :

allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}
	

Add this dependencies also inside project module

ext.sharedGroup = {dependencyHandler->
   delegate = dependencyHandler
    implementation 'com.android.billingclient:billing:5.1.0'
    implementation "androidx.room:room-runtime:2.4.3"
    annotationProcessor 'androidx.room:room-compiler:2.4.3'
    implementation 'com.kaopiz:kprogresshud:1.2.0'
    implementation group: 'com.google.guava', name: 'guava', version: '11.0.2'
}

Why should you add those in project module?

Answer: Those dependencies can be use on every module if you add on project module... So less size, No multidex!

Add this two lines in main module :

 implementation 'com.github.Ucdemir:Ucdemir-Inn_App_Purchase_v2:0.0.6.3'
 sharedGroup dependencies

How to use Library ?

MainActivity:

Create String Array List:

   public static List<String> listOfApplicationSKU;

Add your products names (SKU) :

    listOfApplicationSKU = new ArrayList<>();
       listOfApplicationSKU.add("bor");
       listOfApplicationSKU.add("gas");
       listOfApplicationSKU.add("noads");
       listOfApplicationSKU.add("pro");
       listOfApplicationSKU.add("sun");

Add below code inside your "Main Activity". Those codes check your products status on every application start and returns true results...

   ConnectToPlay.getInstance().initForActivity(this).billingSKUS(DataManager.listOfApplicationSKU).startToWork(ConnectToPlay.CallType.CheckProductStatus).
               setProductStatusGotListener(new ProductStatusGotListener() {
                   @Override
                   public void onProductStatusGot(HashMap<String, Purchase> hashMapPurchaseDetails) {




                   }
               });

Buyout -> Activity / Fragment :

Add below codes inside Buyout -> Activity or Fragment... Those codes get products data’s such as price. Moreover you need "ProductDetails" data in order to buyout item

 ConnectToPlay.getInstance().initForActivity(this).showHud("Loading").startToWork(ConnectToPlay.CallType.GetPriceProducts)
               .setInAppPurchaseListener(new InAppPurchaseListener() {
                   @Override
                   public void returnAllProductsDetailsFromPlayStore(HashMap<String,ProductDetails> hashMapSkuDetails) {
                       ProFragment.this.hashMapSkuDetails = hashMapSkuDetails;
                       setPrice();


                       ConnectToPlay.getInstance().hideHud();
                   }

               });

Example of "setPrice" function (You can also look example) :

private void setPrice(){


       for (Map.Entry<String, ProductDetails> e  : hashMapSkuDetails.entrySet()){

           Log.d("YHY", "price : " + e.getValue().getOneTimePurchaseOfferDetails().getFormattedPrice());

           switch (e.getKey()){

               case "bor":

                   binding.btnOfBor.setText( e.getValue().getOneTimePurchaseOfferDetails().getFormattedPrice());
                   break;
               case "gas":

                   binding.btnOfGas.setText( e.getValue().getOneTimePurchaseOfferDetails().getFormattedPrice());


                   break;

               case "noads":
                   binding.btnOfNoads.setText( e.getValue().getOneTimePurchaseOfferDetails().getFormattedPrice());

                   break;

               case "pro":
                   binding.btnOfPro.setText( e.getValue().getOneTimePurchaseOfferDetails().getFormattedPrice());

                   break;

               case "sun":
                   binding.btnOfSun.setText( e.getValue().getOneTimePurchaseOfferDetails().getFormattedPrice());

                   break;

           }

       }

   }
 

Moreover also create this hasmap in your Activity or Fragment :

   private HashMap<String, ProductDetails> hashMapSkuDetails = new HashMap<>();  

How to Buyout :

       ConnectToPlay.getInstance().startBuyOut(this,hashMapSkuDetails.get("bor")); 

"bor" is product name

How to get status of product :

       ConnectToPlay.getInstance().whatIsProductStatus("bor")

Some Listeners:

Below listener for consume :

setAfterConsumeListener(new AfterConsumeListener() {
            @Override
            public void afterConsume(BillingResult billingResult, String s) {



            }
        });

Below after acknowledge :

setAfterAcknowledgePurchaseResponseListener(new AfterAcknowledgePurchaseResponseListener() {
            @Override
            public void onAcknowledgePurchaseResponse(BillingResult billingResult) {

            }
        });

Below after purchase

setSuccessfullyPurchasedListener(new SuccessfullyPurchasedListener() {
            @Override
            public void successfullyPurchased(String sku) {


            }
        });

Some functions :

At fresh instalation of user set below code true if you want your products to response true... Think that: Your app have ads and you dont want to shown at fresh start

  shouldFirstProductsReturnTrue(true);
  

if you want your app to be restart after purchase you can make below function to be true..

 shouldRestartApp(true)  

How to cunsome product :

    Purchase p = hashMapPurchaseDetails.get("bor");
    ConnectToPlay.getInstance().consumeProduct(p.getPurchaseToken(),p.getDeveloperPayload());
