Description vihsa 2017-07-08 12:25:29 UTC
if the file format HPGL plotting file (.plt) is not yet supported, i request you to add.

Steps to Reproduce:
i am verifying file formats given https://en.m.wikipedia.org/wiki/LibreOffice in libreoffice viewer.

updating my findings at https://github.com/kr1shnas/qa/projects/24.

as of now, i don't know whether libreoffice viewer can read the file. i am unable to find a sample file. if you have a sample file, please provide a link.

if the file format is not yet supported, i request you to add.

Is this issue still relevant?
Supporting more file formats presumably also means that the size of the APK will increase (due to more services that will have to be included), so I tend to suggest focusing on those that are particularly relevant.

In addition, the mechanism to open a file in Android Viewer currently depends on the Android system identifying the proper MIME type, which probably isn't the case for most of the proprietary and not so frequently used file types. (So supporting these might need some "open any file, ignore file type" handling instead (possibly hidden behind a setting?).)
