Object Upload Overview

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference

In OBS, objects are basic data units that users can perform operations on. OBS Android SDK provides abundant APIs for object upload in the following methods:

The SDK supports the upload of objects whose size ranges from 0 KB to 5 GB. For streaming upload, appendable upload, and file-based upload, data to be uploaded cannot be larger than 5 GB. If the file is larger than 5 GB, multipart upload (whose part size is smaller than 5 GB) is suitable. Browser-based upload allows files to be uploaded through a browser.

If the uploaded object can be read by anonymous users. After the upload succeeds, anonymous users can access the object data through the object URL. The object URL is in the format of https://bucket name.domain name/directory levels/object name. If the object resides in the root directory of a bucket, its URL does not contain directory levels.

In the following codes, "bucketname" indicates the name of the bucket to which the object is to be uploaded. "objectname" is the name of the target object that is expected to be generated in the bucket after the upload. The directory levels can be specified, for example, src/src1/src2/test.txt. If no directory level is specified, the object is uploaded to the root directory of the bucket.
