Android支付接入（7）：Google In-app-Billing

今天跟大家一起看下Google的in-app Billing V3支付。

   如果沒有GooglePlay此處附上安裝Google Play的一鍵安裝器的鏈接（需要Root權限）:http://www.muzhiwan.com/com.muzhiwan.gsfinstaller-86095.html

   之前用過Google BillingV2，感覺不太爽。V2版支付走的是異步通知，不能即時得到支付結果，支付、查詢接口太過復雜，還有就是沒找到RestoreOrder接口，因此選擇使用V3版，網上大部分都是介紹GoogleBilling的付費機制原理，具體針對某個功能點的很模糊，所以如果大家想了解GoogleBilling付費機制的這篇博文大可不看，網上轉載多的是，我寫這篇博文的目的是想讓大家快速的將Google支付集成到自己項目中。

   集成Google in-appBilling的前提是你已經正確連接上VPN（大陸用戶），基本上每個公司都會有VPN的，這個找項目組長去要。

  也正式由於天朝的封鎖使得在大陸接Google的支付加大了難度。所以要想接in-appBilling首先要有一個穩定的vpn，PS:非大陸的就行，最好是美、日的。

VPN設置：

注意：類型根據VPN而定，我用的是L2TP/IPSecPSK，選擇此類型時，編輯只需填寫名稱，服務器地址和IPSec預共享密鑰即可，然后連接的時候填寫帳號和密碼。當打開Google商店能看到付費軟件表名VPN已成功連接，如果顯示VPN已連接但還看不到付費軟件時，進入應用程序管理器分別清除GooglePlay服務和Google Play商店數據之后再打開Google商店即可。

源碼下載鏈接為：http://pan.baidu.com/share/link?shareid=1579953623&uk=473193131

   注：源碼導入工程是不可用的，需將包名、版本號、版本code、簽名改為你上傳至Google控制台測試應用的包名、版本號、版本code、簽名，且將MainActivity.java中的Stringbase64EncodedPublicKey ="";填寫上你應用程序的簽名。PS：簽名即Eclipse->AndroidTools->Export Signed Application Package...

   網盤分享中的DemoForGoogleBilling.apk文件是可支付的，但支付會將錢打到我們公司賬戶上，因為我用的是上線app的key。

 

一：接入流程:

   1.申請Google開發者帳號，開發人員控制台左側選擇“設置”填寫測試人員帳號。

   2.添加新應用，此處有個“上傳APK”，此處上傳的apk上傳到Bate版或者ALPHA版，但包名、版本code、版本name、簽名需跟最終上線的產品保持一致。此處上傳測試版本的目的是當你支付接入完畢后測試時用。

    3.集成Google Billing。

     (1).Purchasing Items,購買商品時的通信過程

      (2).Consuming In-app Products,消耗產品時的通信過程

 

    4.測試支付。
      (1).測試支付官方文檔鏈接http://developer.android.com/google/play/billing/billing_testing.html
      (2).Testing with staticresponses，靜態測試，即當支付狀態為一下四種情況時游戲邏輯是否正確。

官方給出的4種如下：

There are four reserved product IDs for testing static In-appBilling responses:

android.test.purchased

When you make an In-app Billing request with this product ID,Google Play responds as though you successfully purchased an item.The response includes a JSON string, which contains fake purchaseinformation (for example, a fake order ID). In some cases, the JSONstring is signed and the response includes the signature so you cantest your signature verification implementation using theseresponses.

android.test.canceled

When you make an In-app Billing request with this product IDGoogle Play responds as though the purchase was canceled. This canoccur when an error is encountered in the order process, such as aninvalid credit card, or when you cancel a user's order before it ischarged.

android.test.refunded

When you make an In-app Billing request with this product ID,Google Play responds as though the purchase was refunded. Refundscannot be initiated through Google Play's in-app billing service.Refunds must be initiated by you (the merchant). After you processa refund request through your Google Wallet merchant account, arefund message is sent to your application by Google Play. Thisoccurs only when Google Play gets notification from Google Walletthat a refund has been made. For more information about refunds,see Handling IN_APP_NOTIFY messages and In-app BillingPricing.

android.test.item_unavailable

When you make an In-app Billing request with this product ID,Google Play responds as though the item being purchased was notlisted in your application's product list.

      例：當配置為android.test.purchased時：

mHelper.launchPurchaseFlow(MainActivity.this,“android.test.purchased”,RC_REQUEST,mPurchaseFinishedListener);

      (3).當游戲邏輯測試通過后，進行支付測試。測試時手機設備上綁定的Google帳號必須是在開發者控制台中配置的測試帳號，綁定非大陸的信用卡，支付后會在開發者控制台看到支付的訂單，由於是測試訂單，可以將測試產生的費用返還給綁定的信用卡。

     測試效果圖如下（由於本人沒有非大陸的信用卡，所以只能看到這個界面，上線項目“蘑菇幫”測試ok）

支付接入過程中涉及到的接口及名詞：

 

一：受管理商品和不受管理商品

   1.受管理商品即不可重復購買的，例如：解鎖關卡，激活游戲等。

   2.不受管理商品即可重復購買的，例如：購買金幣，購買葯水，等消耗品。

   3.訂閱商品，由於項目中沒有涉及到，如有需要的可以翻閱一下Google Billing文檔。

Google in-app BillingV3將所有商品默認為受管理的，如果有不受管理商品則需要調用consumeAsync去消耗調，（或者你可以通俗的理解為，當你成功購買一個道具，Google后台會將此道具加上標記，當你調用consumeAsync將訂單消耗掉時，該訂單標記被取消）。

二：三個回調

  1.IabHelper.OnIabPurchaseFinishedListener 支付完成的回調，如果是受管理的商品在此回調中直接可以將道具給用戶

 

  2.IabHelper.OnConsumeFinishedListener 消耗完成的回調，當不受管理的商品被成功消耗進入此回調，此時將不受管理的商品給用戶

 

    3.IabHelper.QueryInventoryFinishedListener 查詢完成的回調，RestoreOrder的時候用，當有訂單成功付款但由於種種原因（突然斷網、斷電等）沒收到Google支付成功的回調時，在這里可以查詢到此訂單，此時需要對訂單進行處理（給用戶道具等）。

四：測試用的app一定要跟上傳到Google的測試版的包名、版本code、name、簽名一致，否則無法進行支付測試。

    1.當簽名不一致或者版本code、版本name不一致時錯誤界面如下：

      2.當包名不一致時錯誤界面如下：

接下來跟大家一起看一下代碼具體實現：
1.下載in-app-billing-v03，下載地址：http://pan.baidu.com/share/link?shareid=1387554851&uk=473193131將下載后的壓縮包解壓:

將src目錄下兩個包及包中的java文件引入工程，例如：

2.添加權限：

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

3.添加支付代碼：

    初始化IapHelper：

 

String base64EncodedPublicKey ="";此處填寫Google控制台添加新應用程序后的appid
      mHelper =new IabHelper(this, base64EncodedPublicKey);
       // enable debuglogging (for a production application, you should set this tofalse).
      mHelper.enableDebugLogging(false);
    // Start setup. This is asynchronous andthe specified listener
       // will be called oncesetup completes.
       Log.d(TAG,"Starting setup.");
      mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener(){
          publicvoid onIabSetupFinished(IabResult result){
              Log.d(TAG,"Setupfinished.");
             if (!result.isSuccess()) {
                 // Ohnoes, there was a problem.
                 complain("Problemsetting up in-app billing: " + result);
                return;
              }
             iap_is_ok = true;
              //Hooray, IAB is fully set up. Now, let's get an inventory of stuffwe own.
             Log.d(TAG, "Setup successful. Queryinginventory.");
           }
       });

 

  調用支付接口：

 

if(iap_is_ok){
mHelper.launchPurchaseFlow(MainActivity.this,skus[1],RC_REQUEST, mPurchaseFinishedListener);
}else {
showMessage("提示", "GooglePlay初始化失敗,當前無法進行支付，請確定您所在地區支持Google Play支付或重啟游戲再試！");
}

 

  調用查詢接口：

 

mHelper.queryInventoryAsync(mGotInventoryListener);

 

  調用獲取道具價格接口：（因Google市場是根據不同國家顯示不同貨幣價格，所以顯示到游戲道具列表中的價格不是定值，而是動態獲取的）

 

billingservice =mHelper.getService();
Bundle querySkus = newBundle();
   querySkus.putStringArrayList("ITEM_ID_LIST", skus);
try {
Bundle skuDetails = billingservice.getSkuDetails(3,MainActivity.this.getPackageName(),"inapp", querySkus);
ArrayList<String> responseList =skuDetails.getStringArrayList("DETAILS_LIST");
if (null!=responseList) {
for (String thisResponse :responseList) {
          try {
SkuDetails d = newSkuDetails(thisResponse);
 
for (int i = 0; i <sku_list.size(); i++) {
if(sku_list.get(i).equals(d.getSku())) {
price_list.set(i, d.getPrice());
}
}
iapHandler.sendEmptyMessage(0);
 
}catch (JSONException e) {
// TODO Auto-generated catchblock
e.printStackTrace();
}
          
       }
}
}catch (RemoteException e) {
// TODO Auto-generated catchblock
e.printStackTrace();
}

 

  三個回調：

 

// Callback for when a purchase is finished
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener =newIabHelper.OnIabPurchaseFinishedListener() {
      publicvoidonIabPurchaseFinished(IabResult result, Purchase purchase) {
           Log.d(TAG,"Purchase finished: " + result+", purchase: " +purchase);
          if (result.isFailure()) {
             // Oh noes!
              complain("Error purchasing: " + result);
             return;
           }

           Log.d(TAG,"Purchase successful.");
          if(purchase.getSku().equals("coins_100")||purchase.getSku().equals("android.test.purchased")){
          mHelper.consumeAsync(purchase, mConsumeFinishedListener);
}elseif (purchase.getSku().equals("double_income")) {
//受管理的商品,開啟雙倍經驗
showMessage("支付成功","成功購買雙倍經驗");
}
       }
    };
// Called when consumption is complete
IabHelper.OnConsumeFinishedListener mConsumeFinishedListener =newIabHelper.OnConsumeFinishedListener() {
      publicvoid onConsumeFinished(Purchasepurchase, IabResult result) {
          Log.d(TAG,"Consumption finished. Purchase: "+purchase + ", result: " +result);

          // We know this is the "gas"sku because it's the only onewe consume,
          // so we don't check whichsku was consumed. If you havemore than one
          //sku, you probably shouldcheck...
          if (result.isSuccess()) {
              //successfully consumed, so we apply the effects of the item inour
              //game world's logic, which in our case means filling the gas tank abit
          if(purchase.getSku().equals("coins_100")||purchase.getSku().equals("android.test.purchased")){
          showMessage("支付成功","成功購買100貓幣");
    }
           }
          else {
              complain("Error while consuming: " + result);
           }
       }
    };
    
// Listener that's called when we finish querying the items weown
IabHelper.QueryInventoryFinishedListener mGotInventoryListener =newIabHelper.QueryInventoryFinishedListener() {
      publicvoidonQueryInventoryFinished(IabResult result, Inventory inventory){
          Log.d(TAG,"Query inventory finished.");
          if (result.isFailure()) {
              complain("Failed to query inventory: " +result);
             return;
           }

          Log.d(TAG,"Query inventory was successful.");

          if(inventory.hasPurchase("double_income")) {
         //查詢到有受管理的商品支付成功需要將道具給用戶
showMessage("成功Restore雙倍金幣", "查詢到有雙倍金幣需要恢復");
}elseif(inventory.hasPurchase("cions_100")){
//查詢到不受管理的商品支付成功需要將道具消耗掉
showMessage("成功Restore100金幣","查詢到有100金幣需要恢復");
}
       }
    };

 

  處理返回Activity后的數據：

 

@Override
protectedvoid onActivityResult(int requestCode,int resultCode, Intent data) {
// TODO Auto-generated methodstub
Log.d(TAG, "onActivityResult("+ requestCode + "," +resultCode +"," + data);

       // Pass on theactivity result to the helper for handling
      if(!mHelper.handleActivityResult(requestCode, resultCode, data)){
          // not handled, so handle it ourselves(here's where you'd
          // perform any handling of activityresults not related to in-app
          // billing...
          super.onActivityResult(requestCode,resultCode, data);
       }
      else {
          Log.d(TAG,"onActivityResult handled by IABUtil.");
       }
}

 

  退出游戲后銷毀IabHelper：

 

@Override
protectedvoid onDestroy() {
// TODO Auto-generated methodstub
super.onDestroy();
if (mHelper !=null) mHelper.dispose();
      mHelper =null;
}

 

  最后附上MainActivity.java完整文件，源碼下載地址：http://pan.baidu.com/share/link?shareid=1579953623&uk=473193131：
