need Help on modifying the app

[dinidumr]

Hi,

I want to randomly play a video from specific folder(pick one from many videos) every 5 minutes while playing videos on SD card.
Ex: while SD card video is playing (video length is 12 minutes), video should pause and a video(1 minute length) should play from the specific folder and when it finished playing, SD card video should resume playing from 5minutes and once it reaches 10minute another video should play from specific folder. Please help me to kodify the code
