java - 无法在 Android 中创建 Amazon Sqs，但可以在 Java 应用程序中创建它

Question

我无法在 Android 中创建队列，但使用与在 java 应用程序中创建的代码相同的代码。我应该怎么办？

这是我的代码 fragment :

AmazonSQS sqs = new AmazonSQSClient( new BasicAWSCredentials( "access key", "secret key" ));
String Url = sqs.createQueue(new CreateQueueRequest(email)).getQueueUrl();

这是我的堆栈跟踪:

您正在主线程上调用代码 fragment 。您需要在后台线程中运行它。实现此目的的一种方法是使用 AsyncTask .
