Question

我在旧版Android上运行我的应用时遇到问题，因为我在尝试实例化CognitoCachingCredentialsProvider时遇到错误。

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。我还没有尝试其他版本的Android，因为我需要它在Jellybean及以上版本上工作。

有谁知道为什么这会给我一个关于Jellybean而不是Lollipop的错误？代码不会转到Jellybean中的try / catch块，而只会杀死应用程序而Logcat会提供此错误：
