在应用内结算（IAB 版本 3）安卓系统中恢复购买

要使项目可消费，您必须发送消耗请求，并且必须在单独的线程中执行此操作。

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 1111) {
        int responseCode = data.getIntExtra("RESPONSE_CODE", 0);
        String purchaseData = data.getStringExtra("INAPP_PURCHASE_DATA");
        String dataSignature = data.getStringExtra("INAPP_DATA_SIGNATURE");
        Logger.printMessage(TAG, "on activity result reponse"
                + responseCode, Logger.DEBUG);
        if (resultCode == RESULT_OK && responseCode == 0) {
            try {
                JSONObject jo = new JSONObject(purchaseData);
                String sku = jo.getString("productId");
                String title = jo.getString("title");
                addChipsToBalance(sku);
                final String token = jo.getString("purchaseToken");
                Toast.makeText(BuyChipsActivity.this,
                        "You have bought " + title + ". Enjoy the game!",
                        Toast.LENGTH_SHORT).show();

                new Thread(new Runnable() {

                    @Override
                    public void run() {
                        // TODO Auto-generated method stub
                        Logger.printMessage(TAG, "inside run", Logger.DEBUG);
                        try {
                            int response = mService.consumePurchase(3,
                                    getPackageName(), token);
                            Logger.printMessage(TAG, "inside run response"
                                    + response, Logger.DEBUG);
                        } catch (RemoteException e) {
                            // TODO Auto-generated catch block
                            Logger.printMessage(TAG, "exception here 1",
                                    Logger.DEBUG);
                            e.printStackTrace();
                        }
                    }
                }).start();
                // alert("You have bought the " + sku +
                // ". Excellent choice,  adventurer!");
            } catch (JSONException e) {
                // alert("Failed to parse purchase data.");
                e.printStackTrace();
            }
        }
    }

但有时消费请求在Google端未完成，因此您可能需要查询购买的项目列表并使用购买令牌消费它。我喜欢这个

   private void showPreviousPurchases() {
    Logger.printMessage(TAG, "previous purchases", Logger.DEBUG);
    if (mService == null) {
        Toast.makeText(this, "Something Went Wrong. Try later",
                Toast.LENGTH_LONG).show();
        return;
    }
    Bundle ownedItems = null;
    ;
    try {
        ownedItems = mService.getPurchases(3, getPackageName(), "inapp",
                null);
    } catch (RemoteException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    if (ownedItems == null) {
        Logger.printMessage(TAG, "criical error ", Logger.DEBUG);
        return;
    }
    int response = ownedItems.getInt("RESPONSE_CODE");
    if (response == 0) {
        ArrayList<String> ownedSkus = ownedItems
                .getStringArrayList("INAPP_PURCHASE_ITEM_LIST");
        ArrayList<String> purchaseDataList = ownedItems
                .getStringArrayList("INAPP_PURCHASE_DATA_LIST");
    /*  ArrayList<String> signatureList = ownedItems
                .getStringArrayList("INAPP_DATA_SIGNATURE");
        String continuationToken = ownedItems
                .getString("INAPP_CONTINUATION_TOKEN");*/

        for (int i = 0; i < purchaseDataList.size(); ++i) {
            String purchaseData = purchaseDataList.get(i);
            Logger.printMessage(TAG, "json  = " + purchaseData,
                    Logger.DEBUG);
            // String signature = signatureList.get(i);
            String sku = ownedSkus.get(i);

            addChipsAndMakeItConsumable(purchaseData);
            // do something with this purchase information
            // e.g. display the updated list of products owned by user
        }

        // if continuationToken != null, call getPurchases again
        // and pass in the token to retrieve more items
    }

}

private void addChipsAndMakeItConsumable(String purchaseData) {

    try {
        JSONObject jo = new JSONObject(purchaseData);
        String sku = jo.getString("productId");
        // String title = jo.getString("title");
        addChipsToBalance(sku);
        final String token = jo.getString("purchaseToken");
        Logger.printMessage(TAG, "id  = " + sku, Logger.DEBUG);

        Logger.printMessage(TAG, "inside run", Logger.DEBUG);
        try {
            int response = mService.consumePurchase(3, getPackageName(),
                    token);
            Logger.printMessage(TAG, "inside run response" + response,
                    Logger.DEBUG);
        } catch (RemoteException e) {
            // TODO Auto-generated catch block
            Logger.printMessage(TAG, "exception here 1", Logger.DEBUG);
            e.printStackTrace();
        }

        // alert("You have bought the " + sku +
        // ". Excellent choice,  adventurer!");
    } catch (JSONException e) {
        // alert("Failed to parse purchase data.");
        e.printStackTrace();
    }
}

在你的 IabHelper 中.java这是你的 /android-sdk/extras/google/play_billing/samples/ 中的一个例子，输入此代码来获取用户购买的所有项目。这将返回已购买数据的 JSON 数组。您还可以使用“购买.java进行分析，这也可在 samples 文件夹中找到。

     public ArrayList<String> getAllPurchases() throws RemoteException{
     Bundle ownedItems = mService.getPurchases(3, mContext.getPackageName(),"inapp", null);

     int response = getResponseCodeFromBundle(ownedItems);
     logDebug("Owned items response: " + String.valueOf(response));
     if (response != BILLING_RESPONSE_RESULT_OK) {
         logDebug("getPurchases() failed: " + getResponseDesc(response));

     }
     if (!ownedItems.containsKey(RESPONSE_INAPP_ITEM_LIST)
             || !ownedItems.containsKey(RESPONSE_INAPP_PURCHASE_DATA_LIST)
             || !ownedItems.containsKey(RESPONSE_INAPP_SIGNATURE_LIST)) {
         logError("Bundle returned from getPurchases() doesn't contain required fields.");
     }

     ArrayList<String> purchaseDataList = ownedItems.getStringArrayList(RESPONSE_INAPP_PURCHASE_DATA_LIST);
     return purchaseDataList;
}

并进入您的主要活动

 public class MainActivity extends Activity{
  private IabHelper mHelper;
      private String arrayString;
      public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);

    mHelper = new IabHelper(this,"YOUR PUBLIC KEY" );
      mHelper.enableDebugLogging(true);
      mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {

        public void onIabSetupFinished(IabResult result) {

        if (!result.isSuccess()) { // Oh noes, there was a problem.
            Toast.makeText(this,"Problem setting up in-app billing: " + result,Toast.LENGTH_LONG).show();
              return;
          }

        arrayString=mHelper.getAllPurchases().toString();

        Log.d("Purchases: ",""+arrayString);


        array = new JSONArray(arrayString);

        for (int i = 0; i < array.length(); i++) {
            JSONObject row = array.getJSONObject(i);    
            productId=row.getString("productId");  //this will get the product id's that has been purchased.

            Log.e("To be restored:", " PRODUCT ID's "+productId);
        }

      });         
    }
}

我希望这会帮助你。^_^ 谢谢。
