The app is one APK, signed by Opensolr, on the GitHub releases page. Android 8.0 or newer.
01 · From GitHub
- On the phone, open opensolr-pdf-reader.apk, the latest signed release.
- Android asks whether your browser may install apps. Allow it for this install.
- Tap Install. The app is called Opensolr PDF Reader in your app drawer.
02 · From Google Play
- The Google Play build is the same app without any network permission. Google Play installs and updates it.
03 · What it needs
- Android 8.0 or newer.
- No permissions to grant. It reads the PDF another app hands it, or the one you pick on its start screen.
04 · Uninstalling
- Uninstalling removes the app, the count of the apps you share to, and the OCR models it copied next to its files. Your PDFs are not touched: they were never the app’s.
