What is content://cz.mobilesoft.appblock.fileprovider/cache/blank.html?
The URI content://cz.mobilesoft.appblock.fileprovider/cache/blank.html is a path created by the Android operating system and the AppBlock app.
- content:// → This prefix shows that the file or resource is being accessed using Android’s “content provider” system instead of a normal file path.

Why Does AppBlock Use content cz mobilesoft appblock fileprovider cache blank html?

- It is generated by AppBlock only.

- It is simply a blank HTML file stored in your cache.
Unlike malicious links, this URI cannot be used by hackers to harm your device unless you manually share or modify system-level permissions.
How Does content cz mobilesoft appblock fileprovider cache blank html Work in Android?
When you install AppBlock, the app registers a “FileProvider” with Android. This FileProvider allows the app to share internal files using the content:// scheme instead of the traditional file:// scheme.
Here’s the step-by-step process:
- You try to open a blocked app or site.
- AppBlock intercepts the request.
- Instead of loading the real content, it sends you to the blank.html file.
- The FileProvider delivers the cached HTML file safely to the system.
This method makes blocking seamless and avoids crashes that might occur if the app simply stopped the request without replacing it.
