How it works

SimpleFileUpload has two parts. The Android app uploads a file (or a bundle of dumpstate logs) to your server and gets back a short code. Anyone with the code can download the file from the server's web page until it expires or hits its download limit.

1 · Android app

Pick a file or dumpstate logs. The app zips and uploads them.

→

2 · Upload server

Stores it and returns a 6-character code. Share the code; download from the web page.

Android app

Upload any file from device storage
Finds Samsung dumpstate files automatically; multi-select several and send them as one package
Zips files before upload; chunked uploads for large files
Set an expiry time and maximum number of downloads per upload
Upload history with codes to copy and share, and delete from the server

Upload server

Python · Flask · Docker

Lightweight Flask server with a clean download page
Uploads authenticated with a client key
Secure 6-character alphanumeric codes
Chunked upload support for large files
Download limits, expiry times, and automatic cleanup
Runs in Docker; the app needs HTTPS (bring your own cert or self-signed)

Quick start

Run the server with Docker and HTTPS:

docker build -t simplefileupload-server .
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
docker run -p 7777:7777 \
  -e CLIENT_KEY=your-secret-key \
  -v $(pwd)/cert.pem:/app/cert.pem \
  -v $(pwd)/key.pem:/app/key.pem \
  simplefileupload-server

Build the Android app and, in its settings, enter your server URL and the same client key.
Upload a file, share the code, and download it from your server's web page.

Set your own CLIENT_KEY. If you don't, the server falls back to a default key.
