我正在尝试将图像文件上传到aws存储桶但我在设备上有时会遇到此错误，

But after some time, it shows like,
但过了一段时间，它表明，

EDITED :
编辑：
Now I am getting this too ,
现在我也得到了这个，

Really getting frustrated because of this misbehaviour, the code is same but some time it executes perfectly, some times it does not and show the above written error.
由于这种不当行为真的感到沮丧，代码是相同的，但有时它完美地执行，有时它没有并显示上述书面错误。
I am new to aws, I understand that it saves the cognito id into preferneces.
我是aws的新手，我明白它可以将认知内容保存到首选项中。

add this code to the Utils.Java
将此代码添加到Utils.Java中
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;
};
and the amazonS3Client suppose to look like this :
而amazonS3Client假设看起来像这样：
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;
};
