在应用内结算(IAB版本3)android中恢复购买

Question

Google已升级到IAB3(In App Billing版本3).首先,super.onDestroy()错过了示例代码中的问题.

我在http://developer.android.com/google/play/billing/billing_integrate.html的帮助下实施了v3

它在手机上测试,在模拟器中不起作用.它卡在模拟器中.

我的问题是,我没有看到用于恢复交易的API.如何使用IAB3恢复购买？是不是mService.getPurchases(apiVersion, packageName, type, continuationToken).有没有人测试过这个？这是从本地存储的商品返回购买的商品还是恢复购买的商品？卸载应用程序没有continuationToken.应该是null吗？

那么购买状态何时发生变化呢？

请帮忙!

提前致谢.

编辑:

Google已更新In app计费库并解决了该super.onDestroy()问题.他们还添加了一些额外的功能.

要使物品可消耗，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();
            }
        }
    }

但有时消费请求在谷歌端未完成，因此您可能需要查询已购买的商品列表并使用购买令牌来消费它。我确实喜欢这个

   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();
    }
