Problem with video files transmission using airdrop

[yy_mk]

Greetings! I have a problem with sending video files using airdrop between two iphones 5s (both devices have ios 9.3.1 and on both devices oplayer free version is installed). Transmission goes well (without errors and interruptions) and ends correctly, but files (*.avi and *.mkv) just dissapear. After transmission end there is no dialog which offer to choose apps in which files can be opened. It looks like oplayer is not registred in iphone system as application which can open this file type. What is the problem? Transmission of video files using airdrop is an important function for me. Help me please.
