重置android时出错。测验购买

Question

我正在开发我的第一个Android应用程序，它有一些应用内计费功能。过去三天，我一直在研究如何在购买开发者许可证后添加这些应用内购买。我偶然发现了一份指南，它引导我在一个测试程序上取得成功：

http://www.techotopia.com/index.php/An_Android_Studio_Google_Play_In-app_Billing_Tutorial

测试程序效果很好。但是当我将本指南应用到我的 NavigationDrawerFragment 程序时，我遇到了一些问题。就像我在标题中所说的那样，我使用 android.test.purchased 作为 SKU，它似乎只让我不时使用测试购买。

其他时候，我得到"应用程序内计费错误：无法购买项目，错误响应： 7：项目已经拥有"

我已经在清单文件中添加了计费权限，我还对安全性进行了更改。java文件（遵循指南）：

public static boolean verifyPurchase(String base64PublicKey,
                                     String signedData, String signature) {
    if (TextUtils.isEmpty(signedData) ||
            TextUtils.isEmpty(base64PublicKey) ||
            TextUtils.isEmpty(signature)) {
        Log.e(TAG, "Purchase verification failed: missing data.");
        if (BuildConfig.DEBUG) {
            return true;
        }
        return false;
    }

主要活动。java-OnCreate-Log。d代码是故意的

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    String base64EncodedPublicKey =
            "My key that i almost pasted in here :P";

    mHelper = new IabHelper(this, base64EncodedPublicKey);

    mHelper.startSetup(new
                               IabHelper.OnIabSetupFinishedListener() {
                                   public void onIabSetupFinished(IabResult result)
                                   {
                                       if (!result.isSuccess()) {
                                           //Log.d(TAG, "In-app Billing setup failed: " +
                                                   //result);
                                       } else {
                                           //Log.d(TAG, "In-app Billing is set up OK");
                                       }
                                   }
                               });

    mNavigationDrawerFragment = (NavigationDrawerFragment)
            getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
    mTitle = getTitle();

    // Set up the drawer.
    mNavigationDrawerFragment.setUp(
            R.id.navigation_drawer,
            (DrawerLayout) findViewById(R.id.drawer_layout));
}   

其他主要活动。与抽屉碎片无关的java：

private static final String TAG = "com.example.inappbilling";
static final String ITEM_SKU = "android.test.purchased";

public void buyClick(View view) {
    mHelper.launchPurchaseFlow(this, ITEM_SKU, 10001,
            mPurchaseFinishedListener, "mypurchasetoken");
}

@Override
protected void onActivityResult(int requestCode, int resultCode,
                                Intent data)
{
    if (!mHelper.handleActivityResult(requestCode,
            resultCode, data)) {
        super.onActivityResult(requestCode, resultCode, data);
    }
}

IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener
        = new IabHelper.OnIabPurchaseFinishedListener() {
    public void onIabPurchaseFinished(IabResult result,
                                      Purchase purchase)
    {
        if (result.isFailure()) {
            // Handle error
            return;
        }
        else if (purchase.getSku().equals(ITEM_SKU)) {
            consumeItem();
        }
    }
};


public void consumeItem() {
    mHelper.queryInventoryAsync(mReceivedInventoryListener);
}

IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener
        = new IabHelper.QueryInventoryFinishedListener() {
    public void onQueryInventoryFinished(IabResult result,
                                         Inventory inventory) {

        if (result.isFailure()) {
            // Handle failure
        } else {
            mHelper.consumeAsync(inventory.getPurchase(ITEM_SKU),
                    mConsumeFinishedListener);
        }
    }
};


IabHelper.OnConsumeFinishedListener mConsumeFinishedListener =
        new IabHelper.OnConsumeFinishedListener() {
            public void onConsumeFinished(Purchase purchase,
                                          IabResult result) {

                if (result.isSuccess()) {
                    //clickButton.setEnabled(true);
                     Context.MODE_PRIVATE);

                    //Never had this code actually run before, could contain errors
                    //but those aren't the issue to my knowledge.
                    SharedPreferences pref = MainActivity.this.getSharedPreferences("MyPref",
                    SharedPreferences.Editor editor = pref.edit();
                    editor.putBoolean("BoughtTabard",true);
                    editor.commit();
                    FragmentManager fragmentManager = getSupportFragmentManager();
                    fragmentManager.beginTransaction()
                            .replace(R.id.container, TabardGuideNeedToBuy.newInstance(8))
                            .commit();

                } else {
                    // handle error
                }
            }
        };


@Override
public void onDestroy() {
    super.onDestroy();
    if (mHelper != null) mHelper.dispose();
    mHelper = null;
}

不确定我是否只是忽略了一个小问题或其他什么，但非常感谢任何想法/解决方案！

我确实添加了iInApp BillingService。aidl到正确的位置，以及所有9个util文件（Base64、security、SkuDeatils等）

如果出于某种原因。测验购买的物品在应该消费的时候没有被消费，添加consumeItem（）；从if（result.isFailure（））中调用，运行应用程序，重新启动购买流，然后它将崩溃并使用android。测验购买，然后返回代码并删除consumeItem（）；从if内部调用（result.isFailure（）。再次运行该应用程序，然后使用android。测验购买后现在应该可以再次消费。
