I created an app using jquery mobile and dreamweaver....Im having problems with it loading (takes to long)

Good Afternoon everyone. I have created an android app that consists of the study material for a boat mechanic. i went to school to be a marine tech and I decided to take the content of the class and design an app. As the app size grew so has the problem with loading this app on devices. There is a tun of content and I was wondering if there is a way to break up the content so that It does not take forever to load. See  the long load time makes the app quit and I get an error message. my app is on the android market if you wanna see what im working with. 


I am a graphic designer with some code writing know how. I created all content for this app, photos and illustrations.  All these images are linked external to my drop box account.
