Android Cloud Sync program required -- 2

I need native Android code to perform cloud sync.
You have to make a screen where user profile is shown. User can enable / disable sync. User can select between cloud accounts (Google Drive, Dropbox, OneDrive)
There will sync and download button
On tapping sync button, database fill be synced to cloud server in folder MateBilling/{Current Month} {Current Year} e.g. MateBilling/June 2022/myfile.db
On Download button click, latest file will downloaded on SD card as per month
(Note: - You can take any database file with .db extension - Find attached sample screens for this task
- All operations will be performed in background e.g. if later the sync task is scheduled, it should perform automatically at scheduled time
- See attached files for clarification. These are just for explaining purpose. Actual design could be different
- If you are comfortable with only Google Drive or other one along sie, you can still bid but do mention at bidding
- Only experienced candidate should bid
- Start your discussion with sync so that I would you have understood requirements before bidding)
