in-app purchase匯入步驟

以下文章從Billing Android- implementing in-app billing取材整理


1.將Billing Sample src裡的com.android.vending.billing複製到你的專案裡
2.在AndroidManifest.xml裡的user-permission添加
com.android.vending.BILLING
註︰如果沒有宣告就請求billing機制時，將會收到RESULT_DEVELOPER_ERRO反應
3. 建立BroadcastReceiver和Service(見步驟4)

BroadcastReceiver - 用來處理從Android Market傳來的Billing訊息 
Service - 綁剛才從billing sample src複製過來的IMarketBillingService.aidl

哦！對了。AndroidManifest.xml裡的BroadcastReceiver要設 intent filters 

4.攢寫Service
這個Service將要做哪些事？
(1)綁定IMarketBillingService.aidl
(2)向Android Market發佈Billing請求

• CHECK_BILLING_SUPPORTED requests
• REQUEST_PURCHASE requests
• GET_PURCHASE_INFORMATION requests
• CONFIRM_NOTIFICATIONS requests
• RESTORE_TRANSACTIONS requests

(3)同步處理以上這些請求的回應


============================
(1)綁定IMarketBillingService.aidl詳細說明

1. 建立一個Service並實作serviceConnection，然後將底下的Code放進OnCreate()

try {
  boolean bindResult = mContext.bindService(
    new Intent("com.android.vending.billing.MarketBillingService.BIND"), this,
    Context.BIND_AUTO_CREATE);
  if (bindResult) {
    Log.i(TAG, "Service bind successful.");
  } else {
    Log.e(TAG, "Could not bind to the MarketBillingService.");
  }
} catch (SecurityException e) {
  Log.e(TAG, "Security exception: " + e);
}
 

2.  建立callback(將以下程式碼貼進自創的Service裡)

/**
  * The Android system calls this when we are connected to the MarketBillingService.
  */
  public void onServiceConnected(ComponentName name, IBinder service) {
    Log.i(TAG, "MarketBillingService connected.");
    mService = IMarketBillingService.Stub.asInterface(service);
  }
 

3.  可以開始用mService去 sendBillingRequest()任何需求了！

 記得將developer發佈頁面裡的公開金鑰放進Security.java裡的base64EncodedPublicKey變數中
