Android支付接入（7）：Google In-app-Billing

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

String base64EncodedPublicKey ="";此处填写Google控制台添加新应用程序后的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.");
           }
       });

  调用支付接口：

if(iap_is_ok){
mHelper.launchPurchaseFlow(MainActivity.this,skus[1],RC_REQUEST, mPurchaseFinishedListener);
}else {
showMessage("提示", "GooglePlay初始化失败,当前无法进行支付，请确定您所在地区支持Google Play支付或重启游戏再试！");
}

  调用查询接口：

mHelper.queryInventoryAsync(mGotInventoryListener);

  调用获取道具价格接口：（因Google市场是根据不同国家显示不同货币价格，所以显示到游戏道具列表中的价格不是定值，而是动态获取的）

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();
}

  三个回调：

// 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,开启双倍经验
showMessage("支付成功","成功购买双倍经验");
}
       }
    };
// 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","成功购买100猫币");
    }
           }
          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")) {
         //查询到有受管理的商品支付成功需要将道具给用户
showMessage("成功Restore双倍金币", "查询到有双倍金币需要恢复");
}elseif(inventory.hasPurchase("cions_100")){
//查询到不受管理的商品支付成功需要将道具消耗掉
showMessage("成功Restore100金币","查询到有100金币需要恢复");
}
       }
    };

  处理返回Activity后的数据：

@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.");
       }
}

  退出游戏后销毁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，源码下载地址：http://pan.baidu.com/share/link?shareid=1579953623&uk=473193131：
