Object Storage Service:Delete buckets by using OSS SDK for Android

Usage notes

• Before you run the sample code in this topic, you must create an OSSClient instance by using methods such as using a custom domain name or Security Token Service (STS). For more information, see Initialization.

Permissions

By default, an Alibaba Cloud account has full permissions on resources in the account. In contrast, RAM users and RAM roles associated with an Alibaba Cloud account initially have no permissions. To manage resources by using a RAM user or role, you must grant the required permissions via RAM policies or Bucket policies.

Resources to clean up before deleting buckets

Before deleting a bucket, all resources stored within must be cleaned up. In most cases, only objects are stored within buckets. However, a small number of users also need to delete configuration items associated with advanced features. We recommend that you use the OSS console, for it supports automatic detection of resources to clean up before deleting buckets.

• All objects stored stored within the bucket to delete (which applies to the majority of users)

  If the bucket contains a small number of objects, we recommend that you manually delete them. To delete a large number of objects, we recommend that you configure lifecycle rules to delete the objects. In addition, if versioning is enabled for the bucket, both current and historical versions of objects are required to be cleaned up.

• Additional configuration items (which applies to users of advanced features)

  • Parts generated from incomplete multipart upload or resumable upload tasks. For more information, see Delete parts.

  • Access points.

  • Object FC Access Points

  • Accelerators.

  • Livechannels. For more information, see DeleteLiveChannel.

Examples

The following sample code provides an example on how to delete a bucket:

DeleteBucketRequest deleteBucketRequest = new DeleteBucketRequest("bucketName");

// Asynchronously delete the bucket. 
OSSAsyncTask deleteBucketTask = oss.asyncDeleteBucket(deleteBucketRequest, new OSSCompletedCallback<DeleteBucketRequest, DeleteBucketResult>() {
    @Override
    public void onSuccess(DeleteBucketRequest request, DeleteBucketResult result) {
        Log.d("asyncDeleteBucket", "Success!");
    }
    @Override
    public void onFailure(DeleteBucketRequest request, ClientException clientException, ServiceException serviceException) {
        // Handle request exceptions. 
        if (clientException != null) {
            // Handle client exceptions, such as network exceptions. 
            clientException.printStackTrace();
        }
        if (serviceException != null) {
            // Handle service exceptions. 
            Log.e("ErrorCode", serviceException.getErrorCode());
            Log.e("RequestId", serviceException.getRequestId());
            Log.e("HostId", serviceException.getHostId());
            Log.e("RawMessage", serviceException.getRawMessage());
        }
    }
});
