the mime type according to ghost commander, zarchiver and bugzilla is 'video/dv'. when i try to open using vlc for android 2.0.6, it refuses to play. the wikipedia [ 1 ] informs that it is a spreadsheet file format. however, the display is different, please find attachments. .dif screenshot 1 on 5.0.0.0.alpha1+-ab465b9 .dif screenshot 2 on 5.1.0.0.alpha1+1a6ec13 5.1.0.0.alpha1+-5b791ec 5.2.0.0.alpha0+-f6a74ce 5.3.0.0.alpha1+-4136757 6.0.0.0.alpha0+-1e87e93 device: lyf flame 3 [ ls-4001 ] os: android 5.1 [ 1 ] https://en.m.wikipedia.org/wiki/Data_Interchange_Format
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?).)
