Question

我正在尝试在我的应用中实现应用内结算API，但是当我运行我的应用时，它会产生异常。这是我第一次使用应用内结算API。这是我得到的异常的日志：

Answer 1

最后，我得到了整个工作，并没有得到这个异常“IAB助手没有设置。无法执行操作：queryInventory”或我得到的另一个“无法启动异步操作（消耗）因为另一个异步操作（消耗）正在进行中。“

您要做的第一件事是在IabHelper.java类中添加2个方法：

 public boolean isAsyncInProgress(){
    return mAsyncInProgress;
}
public boolean isSetupDone (){
    return mSetupDone;
}

而不是你的主要活动：

public class MainActivity extends AppCompatActivity {
private   IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
    @Override
    public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
        if (result.isFailure()) {
            // handle error here
            Toast.makeText(MainActivity.this,"error",Toast.LENGTH_LONG).show();
        }
        else{
            // does the user have the premium upgrade?
            mIsRemoveAdds = inventory.hasPurchase(SKU_REMOVE_ADDS);
            if(!mIsRemoveAdds) {
                Toast.makeText(MainActivity.this,"no premium",Toast.LENGTH_LONG).show();
                mAdView = (AdView) findViewById(R.id.adView);
                AdRequest adRequest = new AdRequest.Builder().build();
                mAdView.loadAd(adRequest);
            }else{
                mAdView.setVisibility(View.GONE);
                Toast.makeText(MainActivity.this,"premium",Toast.LENGTH_LONG).show();
            }

        }
    }
};
private IabHelper.OnIabPurchaseFinishedListener mPurchasedFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
    @Override
    public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
        if (result.isFailure()) {
            Log.d(TAG, "Error purchasing: " + result);
            return;
        }
        else if (purchase.getSku().equals(SKU_REMOVE_ADDS)) {
            // consume the gas and update the UI
            mIsRemoveAdds = true;
            mAdView.setVisibility(View.GONE);
            Toast.makeText(MainActivity.this,"Purchase successful",Toast.LENGTH_LONG).show();
        }
    }
};

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
String publicKey = s1+s2+s3+s4+s5;

    mHelper = new IabHelper(this,publicKey);
    mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
        @Override
        public void onIabSetupFinished(IabResult result) {
            if (!result.isSuccess()) {
                //error
                Log.d(TAG, "Proglem setting up in-app Billing: " + result);
            }
            if (result.isSuccess()) {
                //Horay, IAB is fully set up!
                Log.d(TAG, "Horay, IAB is fully set up!");
                //queryPurchasedItems;
                mHelper.queryInventoryAsync(mGotInventoryListener);
            }
        }
    });

现在，正如Google guide建议的那样，我们必须检查用户在开始或简历方法中购买了哪些商品。在这里，我们需要在IabHelper.java类中添加两种方法。

   private void queryPurchasedItems() {
    //check if user has bought "remove adds"
    if(mHelper.isSetupDone() && !mHelper.isAsyncInProgress()) {
        mHelper.queryInventoryAsync(mGotInventoryListener);
    }
}

@Override
protected void onStart() {
    super.onStart();
    queryPurchasedItems();
}

@Override
protected void onResume() {
    super.onResume();
    queryPurchasedItems();
    isListEmpty();
}

Answer 2

您的OnIabSetupFinishedListener会检查（！result.isSuccess（））

但是如果结果不成功，你不会返回或中止。

我认为你的mHelper.startSetup失败了，你没有处理这个失败。

未设置IAB助手。无法执行操作：queryInventory
