Question

我正在尝试使用AdvertisingIdClient来获取AIR应用的广告ID。所以我确实喜欢A dvertisingIdClient.Info adInfo = AdvertisingIdClient.getAdvertisingIdInfo(context)。我没有得到任何编译时错误。我从中生成了ANE。当控件遇到此语句时，它会立即抛出NoClassDefFoundError。我不知道到底发生了什么。这是我的扩展代码

public class GetAdvertismentID implements FREFunction
{
    @Override
    public FREObject call(FREContext arg0, FREObject[] arg1)
    {
        Activity activity = arg0.getActivity();
        Context context = activity.getApplicationContext();

        String advertId = "initializeByGet\n";

        try
        {
            AdvertisingIdClient.Info adInfo = AdvertisingIdClient.getAdvertisingIdInfo(context);
            //if (!adInfo.isLimitAdTrackingEnabled())
                    //advertId = advertId + adInfo.getId();
        } catch(Error e) {

            String stackTrace = "";
            StackTraceElement[] stackArray = e.getStackTrace();
            for(int i = 0; i < stackArray.length; i++)
                stackTrace += stackArray[i].toString() + "\n";

            advertId += "Error::::::::::::::::";
            advertId += "\nLocalized Message : " + e.getLocalizedMessage();
            advertId += "\nMessage : " + e.getMessage();
            advertId += "\ntoString() : " + e.toString();
            advertId += "\nCause : " + e.getCause();
            advertId += "\nStack Trace : " + stackTrace;

        } catch (Throwable t) {

            advertId += "\nThrowable::::::::::::";
            advertId += "\nLocalized Message : " + t.getLocalizedMessage();
            advertId += "\nMessage : " + t.getMessage();
            advertId += "\ntoString() : " + t.toString();
        }


        try
        {
            return FREObject.newObject(advertId);
        }
        catch(Exception e)
        {
            return null;
        }
    }
}

当我在生成ANE后执行此操作时，我将得到此输出：

我觉得这里的问题是，它无法在运行时找到某个类的路径。所以我尝试了所有选项： Using the new Android Advertiser id inside an SDK， How do I disable proguard for building my Android app?， http://jmsliu.com/2143/add-admob-ads-in-flash-based-android-apps.html 不幸的是，它们都没有奏效。如果你们有人这样做，请帮助我。我正在使用Flash Builder 4.7和AIR SDK 14.0。

创建ANE时，最好从JAR中提取google-play-services类，并将它们包含在ANE的JAR中。请参阅this。

如果最终APK本身内的类仍然缺失，请查看my question（以及随后的答案）以查找类似问题。我试图将最新的Google Play服务SDK集成到我们的游戏中，我注意到AIR SDK中的dx工具正在剥离Google Play类。您可以使用this tool来确认这一点，以验证最终APK中是否确实缺少这些类。

更新：

我之前使用上面提到的相同的dex2jar工具将所需的类注入到APK中。但这不是必要的。您只需更新AIR SDK中的dx工具即可。

AdvertisingIdClient.getAdvertisingIdInfo（context）正在阻止NoClassDefFoundError
