我正在尝试在应用计费中实现。我按原样使用了 trivialdrivesample。

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

    // load game data
    loadData();


    String base64EncodedPublicKey = "my key";



    // Create the helper, passing it our context and the public key to verify signatures with
    Log.d(TAG, "Creating IAB helper.");
    mHelper = new IabHelper(this, base64EncodedPublicKey);

    // enable debug logging (for a production application, you should set this to false).
    mHelper.enableDebugLogging(true);

    // Start setup. This is asynchronous and the specified listener
    // will be called once setup completes.
    Log.d(TAG, "Starting setup.");
    mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
        public void onIabSetupFinished(IabResult result) {
            Log.d(TAG, "Setup finished.");

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

            // Hooray, IAB is fully set up. Now, let's get an inventory of stuff we own.
            Log.d(TAG, "Setup successful. Querying inventory.");
          //  mHelper.queryInventoryAsync(mGotInventoryListener);
        }
    });
}

Button purchaseB = (Button)findViewById(R.id.purchase_button);

 if(purchaseB != null)
     purchaseB.setOnClickListener(new View.OnClickListener() {
     public void onClick(View v) {

         onUpgradeAppButtonClicked(null);

      }
  });

它运行良好，我可以从我的测试帐户购买。

但问题是我必须注释代码行

//mHelper.queryInventoryAsync(mGotInventoryListener); 所以我无法查询库存。在调试时我发现了那个变量

// Is setup done?
    boolean mSetupDone = false; 

在 IabHelper 类中为 false 并引发异常。说设置成功后的日志说 IAB 助手未设置。

最佳答案

试试这个。

设置:

mIabHelper = new IabHelper(this, ProjectKonstants.APP_PUBLIC_KEY_GOOGLE_PLAY);

mIabHelper.startSetup(new IabHelper.OnIabSetupFinishedListener()
{
    public void onIabSetupFinished(IabResult result)
    {
        if (result.isSuccess())
        {
            mIabHelper.queryInventoryAsync(mInitialInventoryListener);
        }
    }
});

mInitialInventoryListener = new IabHelper.QueryInventoryFinishedListener()
{
    public void onQueryInventoryFinished(IabResult result, Inventory inventory)
    {
        if (result.isSuccess())
        {
            mBHasDonated = inventory.hasPurchase(ProjectKonstants.APPLICATION_SKU_FOR_DONATION);
        }
        else
        {
            mBHasDonated = false;
        }
    }
};

mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener()
{
    public void onIabPurchaseFinished(IabResult result, Purchase purchase)
    {
        if (result.isSuccess())
        {
            if (purchase.getSku().equals(ProjectKonstants.APPLICATION_SKU_FOR_DONATION))
            {
                mBHasDonated = true;
                return;
            }
        }
        mBHasDonated = false;
    }
};

点击升级按钮时:

AccountManager accountManager = (AccountManager) getSystemService(ACCOUNT_SERVICE);
Account[] accounts = accountManager.getAccounts();
String strIdentifier = "[" + accounts[0].name + "][" + android.os.Build.MODEL + "][" + android.os.Build.VERSION.RELEASE + "]";
try
{
    mIabHelper.launchPurchaseFlow(this, ProjectKonstants.APPLICATION_SKU_FOR_DONATION, 10001, mPurchaseFinishedListener, strIdentifier);
}
catch (IllegalStateException e)
{
}

关于android - 在应用内结算 IAB 设置成功但 queryInventory 报告 IAB 助手未设置，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18015170/
