File Associations in Android?

Question

Android

I am writing a diploma for Android, namely a VRML browser.
So far, I select the file I need to read in the self-written file manager.
I would like to put an association on * .wrl-files for greater beauty.
I read it here, but the MIME type of the *.wrl file is hardly embedded in the android firmware, and how to make an association by file extension is not indicated.
Can anyone help?

Answer 1

<data android:mimeType="text/plain" android:pathPattern="*.wrl"/>
