Android应用内结算 – queryInventoryAsync返回0结果

我在使用应用内结算流程时遇到了令人沮丧的问题.
我在开发控制台中创建了一个新的应用程序,添加了一个名为“P1”的inapp产品,该产品目前处于活动状态;我已经将我的应用程序上传到alpha版本的商店,然后升级到测试版,添加了测试人员帐户并在使用测试人员帐户签署的设备(平板电脑)上安装了apk,并使用开发帐户进行了安装.

现在,我想查询商店以获取非拥有skus价格等信息.
这是我的活动代码：

private void istantiate() {
     List<String> tmp = new List<String>();
     tmp.add("P1");
     final List<String> skus = tmp;
     mHelper = new IabHelper(mContext,base64EncodedPublicKey);
     // enable debug logging (for a production application,you should set this to falsE).
     mHelper.enableDebugLogging(true);
     //create listener
     bListener = new BillingListener(mHelper,mContext);

     // Start setup. This is asynchronous and the specified listener will be called once setup completes.
     mHelper.startSetup(new IabHelper.onIabSetupFinishedListener() {
         public void onIabSetupFinished(IabResult result) {

             if (!result.issuccess()) {
                 // There was a problem.
                 return;
             }             
             geTinventory(skus);
         }
     });         
}

...

private void geTinventory(List<String> skuList) {
    // Have we been disposed of in the meantime? If so,quit.
    if (mHelper == null) return;

    // IAB is fully set up. Now,let's get an inventory of stuff we own.
    mHelper.queryInventoryAsync(true,skuList,bListener.mQueryFinishedListener);
}

然后在查询完成时,调用这段代码：

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

      if (result.isFailure()) {
         // handle error
         return;
       }
      ...

   }
};

但退回的库存是空的.这是logcat：

自我的inapp产品发布以来大约一周,所以这不是时间问题.
我试图清除应用数据,然后重启设备.

编辑：使用android.test.purchased作为测试sku,一切正常.
编辑2：SKU是“非托管”
