Build and upload to Google Drive

The helper script can build an APK and upload it to a Google Drive folder through rclone. The uploaded filename contains the app version from app/version.properties, the upload date, and the build variant: Convert X 2.1.3 (19.09.2026) release.apk.

Configure an authenticated Google Drive remote once:

rclone config

Create a remote named gdrive with the Google Drive storage type. Then run:

./scripts/build-and-upload-drive.sh

Useful variants:

./scripts/build-and-upload-drive.sh --variant debug
./scripts/build-and-upload-drive.sh --variant both
./scripts/build-and-upload-drive.sh --folder "Convert X" --remote gdrive
./scripts/build-and-upload-drive.sh --variant release --no-upload

The default destination is the Convert X folder in the configured Drive remote. Override it with --folder or the DRIVE_FOLDER environment variable. The script does not store Google credentials in the repository.
