Answer 1

您需要再次購買之前要消耗的物品..

IabHelper mHelper = new IabHelper(ACTIVITY, base64EncodedPublicKey); 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    // Pass on the activity result to the helper for handling 
    if (!mHelper.handleActivityResult(requestCode, resultCode, data)) { 
     super.onActivityResult(requestCode, resultCode, data); 
    } 
    else { 
     Log.d(TAG, "onActivityResult handled by IABUtil."); 
    } 
}

舉個例子在Android Developer site中給出的項目 命名爲TrivialDrive我們可以使用purch ased項目如下...

// Check for gas delivery -- if we own gas, we should fill up the tank immediately 
    Purchase gasPurchase = inventory.getPurchase(SKU_GAS); 
    if (gasPurchase != null && verifyDeveloperPayload(gasPurchase)) { 
     Log.d(TAG, "We have gas. Consuming it."); 
     mHelper.consumeAsync(inventory.getPurchase(SKU_GAS), mConsumeFinishedListener); 
     return; 
    } 

// Called when consumption is complete 
IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = new IabHelper.OnConsumeFinishedListener() { 
    public void onConsumeFinished(Purchase purchase, IabResult result) { 
     Log.d(TAG, "Consumption finished. Purchase: " + purchase + ", result: " + result); 

     // if we were disposed of in the meantime, quit. 
     if (mHelper == null) return; 

     // We know this is the "gas" sku because it's the only one we consume, 
     // so we don't check which sku was consumed. If you have more than one 
     // sku, you probably should check... 
     if (result.isSuccess()) { 
      // successfully consumed, so we apply the effects of the item in our 
      // game world's logic, which in our case means filling the gas tank a bit 
      Log.d(TAG, "Consumption successful. Provisioning."); 
      mTank = mTank == TANK_MAX ? TANK_MAX : mTank + 1; 
      saveData(); 
      alert("You filled 1/4 tank. Your tank is now " + String.valueOf(mTank) + "/4 full!"); 
     } 
     else { 
      complain("Error while consuming: " + result); 
     } 
     updateUi(); 
     setWaitScreen(false); 
     Log.d(TAG, "End consumption flow."); 
    } 
}; 

希望!!!它幫助你。你可以通過這個例子項目。
