it should show list of external application

i guess you have defined a Default already.... Answered to use the selected app as default.

Remove the Default from the Android Setting and try again.

Actually When I Open from "EsFile Explorer",then Its showing all External application,but When I run from above code its not showing .....

is the path accessible from other apps?
DOCX,XLSX,PPTX did not work , you cut 3 chars here

.SubString(StrFileName.Length-3)

better split by dot starting from right side of filename.

ok noted...

Is it possible to Remove the Default from the Android Setting via Code ???
