但一段时间后，它显示了像，

D/CognitoCachingCredentialsProvider: Identity id is changed

12-12 11:27:26.161 11239-14564/D/CognitoCachingCredentialsProvider: Saving credentials to SharedPreferences

编辑：

现在我得到这个也

I/AmazonHttpClient: Unable to execute HTTP request: SSL handshake timed out 
                     java.net.SocketTimeoutException: SSL handshake timed out 

Caused by: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x1e5dff8: Failure in SSL library, usually a protocol error 
                    error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure (external/openssl/ssl/s23_clnt.c:658 0x401d6cf5:0x00000000)

                     ... 23 more

真的是因为这个行为不当感到沮丧，代码是相同的，但一段时间后它执行完美，有时它不并显示上面写错误。

我是新来的AWS，据我所知，这样可以节省cognito ID为preferneces。

您的设备没有做到SSL握手与服务器。 Cognito支持SSLv3到TLSv1.2。我建议你在不同的设备或模拟器上运行该示例。 – Yangfan

是否有任何解决方案使其在所有设备上都能正常工作 – Custadian

从理论上讲，它应该适用于所有Android设备。自Android API级别1以来，支持TLSv1。但是，由于Android设备的碎片化，说不同的API级别，不同的制造商，根源与否，无法保证它适用于所有设备。你能否分享你的设备信息？ – Yangfan

这个代码添加到Utils.Java

private static CognitoCachingCredentialsProvider getCredProvider(Context context) { 
    if (sCredProvider == null) { 
     ClientConfiguration clientConfiguration = new ClientConfiguration(); 
     clientConfiguration.setConnectionTimeout(30000); 
     clientConfiguration.setSocketTimeout(30000); 
     sCredProvider = new CognitoCachingCredentialsProvider(
       context.getApplicationContext(), 
       Constants.COGNITO_POOL_ID, 
       Regions.fromName(Constants.COGNITO_POOL_REGION),clientConfiguration); 
    } 
    return sCredProvider; 
};

和amazonS3Client猜想是这样的：

 public static AmazonS3Client getS3Client(Context context) { 
    if (sS3Client == null) { 
     sS3Client = new AmazonS3Client(getCredProvider(context.getApplicationContext())); 
     sS3Client.setRegion(Region.getRegion(Regions.fromName(Constants.BUCKET_REGION))); 

    } 
    return sS3Client; 
};
