Android 应用内计费服务在某些设备上不可用

我正在应用程序中使用应用内付费购买。下面是我使用makerequestbundle的代码

protected Bundle makeRequestBundle(String method) {
Bundle request = new Bundle();
request.putString(BILLING_REQUEST, method);
request.putInt(API_VERSION, 1);
request.putString(PACKAGE_NAME, getPackageName());
return request;
}

下面是我用于购买请求的代码

  Bundle response = mService.sendBillingRequest(request);
  Integer responseCodeIndex     = (Integer) response.get("RESPONSE_CODE");
  PendingIntent pendingIntent = (PendingIntent)       
  response.get("PURCHASE_INTENT");
  PendingIntent pendingIntent1 = (PendingIntent) response.get("BUY_INTENT");
  Long requestIndentifier   = (Long) response.get("REQUEST_ID");
  BillingConstants.ResponseCode responseCode =       
  BillingConstants.ResponseCode.valueOf(responseCodeIndex);
  Log.i(TAG, "REQUEST_PURCHASE Sync Response code: "+responseCode.toString());

此代码给出错误，Android 5.0上不提供此服务
