Android AWS CognitoCachingCredentialsProvider在API 17中崩溃应用程序 - JellyBean

Question

我在运行旧版Android应用程序时遇到问题，因为尝试实例化CognitoCachingCredentialsProvider时出现错误。

CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
        this, 
        this.getString(R.string.identity_pool_id), 
        Regions.DEFAULT_REGION); 

这适用于Lollipop 5.0，虽然它在Jellybean 4.4.2（API 17）上崩溃了我的应用程序。我还没有尝试过其他版本的Android，因为我需要它在Jellybean和更高版本上工作。

有谁知道为什么这会给我一个错误的果冻豆，而不是棒棒糖？该代码不走在我的Jellybean try/catch块，而不是它只是杀死了应用程序，并提供logcat中此错误：

找到了解决办法。这是因为MultiDex不适用于较旧版本的Android（在棒棒糖之前）。以下是解决方案对任何有此问题的人的链接：Unable to execute dex: method ID not in [0, 0xffff]: 65536
