IABヘルパーが設定されていません。操作を実行できません：queryInventory

アプリにアプリ内課金APIを実装しようとしていますが、アプリを実行すると例外がスローされます。アプリ内課金APIを扱うのはこれが初めてです。これは私が得ている例外のログです：

最後に、すべてが機能し、この例外が発生しませんでした "IABヘルパーが設定されていません。操作を実行できません：queryInventory"または "非同期操作を開始できません（消費）別の非同期のため操作（消費）が進行中です。」.

最初に行う必要があるのは、IabHelper.Javaクラスに2つのメソッドを追加することです。

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

そしてあなたの主な活動より：

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);
            }
        }
    });

そして今、GoogleのAPIで推奨されている guide では、startメソッドまたはresumeメソッドでユーザーが購入したアイテムを確認する必要があります。ここでは、IabHelper.Javaクラスに追加した2つのメソッドが必要です。

   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();
}

OnIabSetupFinishedListenerは（！result.isSuccess（））をチェックします

ただし、結果が成功しない場合は、ここに戻ったり中止したりしません。

あなたのmHelper.startSetupが失敗し、この失敗を処理していないと思います。
