Android的工作室 - 亞馬遜移動廣告 - 不能實例類com.amazon.device.ads.AdLayout

我試圖將亞馬遜的移動廣告，但保持運行到一個問題，即Android Studio中說：Android的工作室 - 亞馬遜移動廣告 - 不能實例類com.amazon.device.ads.AdLayout

Rendering Problems 
The following classes could not be instantiated: 
- com.amazon.device.ads.AdLayout(Open Class, Show Exception) 
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE

當點擊「顯示異常」：

我試圖按照概述了https://developer.amazon.com/public/apis/earn/mobile-ads/docs/quick-start的步驟，但不包括他們爲Android工作室。

至於我的項目： - 我在我的項目的libs文件夾中有amazon-ads-5.1.153.jar，並將它添加爲一個庫。

在項目結構中，我將庫添加到我的主模塊中，檢查導出。
增加了行到我的清單：

依賴{ 編譯文件（「庫/亞馬遜廣告 - ：
而且我的build.gradle中，我已經加入5.1.153.jar'） }

而且從他們的例子中的一個視圖是複製粘貼：

<com.amazon.device.ads.AdLayout 
     android:id="@+id/adView" 
     android:layout_width="320dp" 
     android:layout_height="50dp" 
     Amazon:adSize="320x50"/>

你看到什麼，當你點擊「顯示異常「鏈接？ –

我已添加它發佈的例外。至於Facebook的問題，我不明白我如何使用.isInEditMode（），因爲AdLayout是編譯代碼，我不能編輯它。 –

如果你在XML佈局，那麼我知道發生了什麼。它應該顯示你的佈局是什麼樣的，它不能渲染它，因爲它不會加載更復雜的代碼... 嘗試模擬器和/或連接物理設備並以這種方式加載應用程序。這對我來說很有用。
