Creating Custom Attachments on Android

In Stream Chat's Android SDK, attachments within messages can be customized beyond the default rendering, which presents images in a gallery layout, files in a list, and links with rich previews. By utilizing the AttachmentViewFactory class, developers can override the createAttachmentView method to implement custom attachment views, such as a password attachment that hides its content by default. This custom attachment can be sent by creating an Attachment object with specific data and adding it to a Message object. While extending AttachmentViewFactory allows for simpler customizations, developers can also fully customize the message rendering for more control at the expense of losing default UI elements. These capabilities enable developers to tailor the chat experience by adding unique content types like maps or product details to messages.
