+    	General remarks about file ending conventions:

+        - *.asc for ascii armored files

+        The actual content can be anything.

+        
+        Remarks about the ugly android:pathPattern:
+        We are matching all files with a specific file ending.
+        This is done in an ugly way because of Android limitations.
