如何使用Android SDK为Amazon推送SNS设置应用程序ARN

我正在尝试注册我的Android设备以接收推送通知，但是amazon服务器返回一个错误，说它找不到我的PlatformApplicationArn。我正在使用他们的sdk进行设置，但似乎找不到它

这就是错误： AWS错误消息：无效参数：PlatformApplication错误原因：所需参数没有值

这是发送它的代码：

String platformApplicationArn = "arn:aws:sns:us-east-1:897955111111:app/GCM/com.myapp";
AWSCredentials awsCredentials = new BasicAWSCredentials("XXXXXXXX", "XXXXXXXXXXXXXXXXXXXXX");
pushClient = new AmazonSNSClient(awsCredentials);
CreatePlatformEndpointRequest createPlatformEndpointRequest = new CreatePlatformEndpointRequest();
String customPushData = "my custom data";
CreatePlatformEndpointRequest platformEndpointRequest = new CreatePlatformEndpointRequest();
platformEndpointRequest.setCustomUserData(customPushData);
platformEndpointRequest.setToken(pushNotificationRegId);
platformEndpointRequest.setPlatformApplicationArn(platformApplicationArn);
CreatePlatformEndpointResult result = pushClient.createPlatformEndpoint(createPlatformEndpointRequest);

您有两个实例

CreatePlatformEndpointRequest

，您在其中一个实例上设置了令牌和applicationArn，但在SNSClient请求中使用了另一个实例，因此它缺少必需的参数

String platformApplicationArn = "arn:aws:sns:us-east-1:897955111111:app/GCM/com.myapp";
AWSCredentials awsCredentials = new BasicAWSCredentials("XXXXXXXX", "XXXXXXXXXXXXXXXXXXXXX");
AmazonSNSClient pushClient = new AmazonSNSClient(awsCredentials);
//probably no need for this
String customPushData = "my custom data";

CreatePlatformEndpointRequest platformEndpointRequest = new CreatePlatformEndpointRequest();

platformEndpointRequest.setCustomUserData(customPushData);
platformEndpointRequest.setToken(pushNotificationRegId);
platformEndpointRequest.setPlatformApplicationArn(platformApplicationArn);

CreatePlatformEndpointResult result = pushClient.createPlatformEndpoint(platformEndpointRequest);

另外，除非您的SNS应用程序区域是US_EAST_1，否则我发现您必须手动设置区域，否则您将收到不匹配的区域错误响应，因此在调用

createPlatformEndpoint（）

之前，请按如下方式设置您的区域：

//Replace with whatever region your app is
pushClient.setRegion(Region.getRegion(Regions.US_WEST_2));

刚刚遇到这个问题--SDK没有使用记录在案的区域确定方法@。我创建了。897955111111这个值来自哪里？这是你的gcm项目id吗？
