MeiCam SDK For Android  3.1.2
License file

There are two licenses for Meishe SDK: SDK license and package license. The SDK license and the package license must be used together, either both or neither. The difference is that the SDK watermark will appear in the program without using the license. Otherwise watermark will be removed. Meishe SDK provides various types of materials including stickers, filters, themes, transitions, etc. Each type of material contains multiple material packages. And each material package corresponds to one material package license. If developers want to use the SDK, the license file is required, which is provided by Meishe SDK's support team.
