How do i package an android game for mac?

Hey if anyone has made a game for the Android phone i need help with packaging the game,
I believe I mess up some were in the whole set up prosses for exporting the game to android.
inside of the “NVPACK” folder, I’m missing the JDK file for java, if anyone can help me through the prosses for mac it would be a big help.
this is the final step for testing the game and I have been stuck for 2 days now
