What is AppBlock?

Now known as Blockr, it is a mobile application designed to enhance professional productivity, currently available for download on both iOS and Android platforms.

AppBlock helps users increase their attention span by blocking the usage of designated apps, notifications, and websites.

Key features

• Blocking of apps based on schedules and geolocation.
• Suppression of notifications.
• Activation of focus mode.
• Restriction to specific web pages.
• Monitoring application usage metrics.
• The AppBlock package name is cz.mobilesoft.appblock.

Here, CZ refers to the Czech Republic, which is the location of the developing company MobileSoft.

What Does content://cz.mobilesoft.appblock.fileprovider/cache/blank.html Mean?

Let’s break it down:

This file is not dangerous and cannot be accessed as a website. It is purely internal to AppBlock and helps the app to neutralize or redirect self-contained undo blocking processes.

What is FileProvider in Android?

With Android’s FileProvider feature, apps can provide content URIs to share files securely with other apps, unlike the traditional file URIs.

Benefits:

• Improved Security
• Does not require exposing raw references
• Commonly found in applications that manage or block files.
• In these cases, FileProvider serves blank web pages instead of the restricted content.

Why Does AppBlock Use Blank.Html?

Here are a few common examples:

1. Blocked URL Redirects

If there is a Blocked Access policy for specific websites like Facebook or YouTube, whenever users try to access those pages, they will be redirected to a blank page through the Blocked Access app.

This lets users pay attention to only a single task instead of multitasking.

2. Dummy Page or Placeholder

This HTML file is utilized as a placeholder to prevent potential crashes of a website and stop a user from being redirected to random pages.

3. Prevent Content Loading or Tracking

Replacing ad trackers with blank.htm helps enhance security and privacy.

SEO Related Use Cases: For Possible Reasons Why This URI is Encountered

As to why this particular URI might show up, these are some possibilities:

Use Case Reason

• A website is blocked by AppBlock.
• To help users focus, AppBlock tries to redirect users to a blank page on purpose.
• An in-app browser is blocked by AppBlock. The in-app browser tries to load some content but ends up receiving nothing.
• Checking Internal Browser Cache.
• The content URI is stored in the system cache or file caches.

Analyzing Log Files on Android During certain app evaluations, some power users or developers could analyze DEBUG log files that had this information.

Can AppBlock remove cache or blank HTML files?

Yes, these files can be removed from the AppBlock cache folder.

How to Remove It Section > Settings > Apps > AppBlock.

Go to Storage & Cache.

Press Clear Cache and confirm.

Resetting the cache doesn’t impact the settings configured for the application, nor does it change any stored data within the application.

Is There A Privacy Concern?

Applying blank.html as a file through FileProvider has no known privacy risks. It achieves the goal of safeguarding sensitive information like personal data and URLs during app-level block and redirection, so other apps cannot reach them.

Taking all of these into account,

Avoid downloading AppBlock from the Google Play Store or any other untrusted site.

To enhance data protection, potential application vulnerabilities should be resolved through ongoing maintenance, ensuring that all updates are executed promptly.

For Developers: Use Cases of content://…/blank.html

In mobile applications, there could be reasons for including blank.html, like:

– Giving no answer when content is denied.

– Testing WebView loading performance.

– Halting the rendering of certain content.

– Working around Android’s restrictive file access with FileProvider.
