Technical Side: What Developers Need to Know About FileProvider
AppBlock uses Android’s FileProvider to share the blank.html file safely. This tool was added in Android 7.0 to stop apps from giving away full file paths. Instead, it creates a short, temporary address like content cz mobilesoft appblock fileprovider cache blank html.
In the app’s code, developers add a few lines in the manifest file and create a simple XML file that says “yes, other parts of the app can read the cache folder.” This keeps everything secure and fast. The blank.html file is tiny — just a few lines of empty HTML — so it loads in less than a second.
If you are a developer building your own focus app, you can copy this pattern. It gives users a smooth experience without slow redirects or error pages.
Privacy and Data in AppBlock
MobileSoft s.r.o. follows strict rules. The app only needs the permissions you give during setup. It does not sell your data or send your browsing history anywhere. The blank page never connects to the internet — it stays on your device. You can read the full privacy policy on the official AppBlock website for peace of mind.
