How to add a Customized WhatsApp Sticker from firebase into WhatsApp without Content Provider?

Question

I got lots of java files and the mechanism for adding a sticker to WhatsApp. I'm working on memes app that include stickers as well. I wanna let the user add a customized sticker to WhatsApp. My app implements Room, View-Model, Repository Pattern and lots of features, so I got a snippet from WhatsApp source code for android that shows the intent action as well. but I just wanna simple one so.

I just want to:

• load sticker from firebase
• store it in files
• change the extension to webp
• when the user clicks on the save button it would add it to WhatsApp.

I can do all the above steps but for the last one, I need simplified code to save it. is there any way to add sticker without creating Content Provider

WhatsApp Sticker Intent

Thanks in advance

Answer 1

First, you cannot just change any image format to .webp just by changing extension.
You'll have to properly change the format.

Second, a ContentProvider is the most important part here that will allow WhatsApp to communicate with your App to know about the sticker files (Images).
So No, you cannot just add a sticker pack to WhatsApp without implementing the appropriate ContentProvider.

Check the ContentProvider implementation here & change it according to your logic.
