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

我在旧版本的Android上运行我的应用程序时遇到问题，因为我在尝试实例化CognitoCachingCredentialsProvider时出错

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

这在棒棒糖5.0上有效，尽管它会使我在Jellybean 4.4.2（API 17）上的应用程序崩溃。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

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

有人知道为什么这会给我一个关于果冻豆而不是棒棒糖的错误吗？该代码不会进入Jellybean中的my try/catch块，而是杀死应用程序，Logcat提供以下错误：

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