This topic describes how to delete an object.

Warning Delete an object with caution because a deleted object cannot be recovered.

Run the following code to delete an object:

// Create a delete request
DeleteObjectRequest delete = new DeleteObjectRequest("<bucketName>", "<objectKey>");
// Delete an object by calling the asynchronous interface.
OSSAsyncTask deleteTask = oss.asyncDeleteObject(delete, new OSSCompletedCallback<DeleteObjectRequest, DeleteObjectResult>() {
    @Override
    public void onSuccess(DeleteObjectRequest request, DeleteObjectResult result) {
        Log.d("asyncCopyAndDelObject", "success!");
    }

    @Override
    public void onFailure(DeleteObjectRequest request, ClientException clientExcepion, ServiceException serviceException) {
        // Handle the exceptions returned for the request.
        if (clientExcepion != null) {
            // A local exception (such as network exception) occurs.
            clientExcepion.printStackTrace();
        }
        if (serviceException != null) {
            // A service exception occurs.
            Log.e("ErrorCode", serviceException.getErrorCode());
            Log.e("RequestId", serviceException.getRequestId());
            Log.e("HostId", serviceException.getHostId());
            Log.e("RawMessage", serviceException.getRawMessage());
        }
    }
});
Notice To call DeleteObject to delete an object, you must have the write permission on the bucket that stores the object.
