Please help Me

Dear App Inventor,

Please let my package to make build up and it says sorry it cant be packaged because your file is larger than 5 MB My current Package MB is 23,58MB Can you help me to make it please

In AI2 on the Internet the aia can not be larger than 5Mb. You may have put images or other resources in your Media (resources) that you do not use in the app. 

 All the images and sounds in resources count toward the 5Mb limit along with the source code.    You can program 

apps larger than 5Mb in the browser, but the apps will not compile and might not run in the 

emulator or the project may not save as an aia. If this is the case you need to reduce 

the size of your image and/or sound files.   Most image files can be made quite small 

by re-sizing them using a photo manipulation program on your PC to less than 50Kb each.

Actually I wanted to build a music mp3 player so I uploaded the mp3 files through it that's why
