Android custom file extension

Question

I have my own file extension, for example .foo, with which I want to link my application. I created this Intent-Filter:

 <intent-filter>
            <action android:name="android.intent.action.VIEW"/>
            <category android:name="android.intent.category.DEFAULT"/>
            <category android:name="android.intent.category.BROWSABLE"/>
            <!--data android:scheme="file" android:pathPattern=".*\\.foo"/-->
            <data android:scheme="file" android:mimeType="*/*"  android:pathPattern=".*\\.foo" android:host="*"/>
 </intent-filter>

The problem is that this does not work on some devices. For example, for Samsung Galaxy S3 (version for Android: 4.4.2) only the following works:

<data android:scheme="file" android:mimeType="*/*"  android:pathPattern=".*\\.foo" android:host="*"/>

However, with LG G2 (Android version: 4.4.2), only this line works:

<data android:scheme="file" android:pathPattern=".*\\.foo"/>

To make it even worse, Nexus 7 (Android version: 5.0) doesn't seem to recognize the end of user files at all.

Has anyone had a similar problem and knows a solution?
