I don't know how to export a game for PCs. So, can I submit it in the form of an Android game? Will it be fine?

Any type of game is accepted for the jam however keep in mind that people will be downloading, playing and voting on your jam entry after the jam has concluded. So it'd be best to also include some form of PC or browser playable version.

Ok, I will try to make a browser playable verison. Thank you
