Is there a way to make an encyclopedia?

Hello dear helpers (please translate)
I made an encyclopedia application. In summary: I created an application using the hide show option by selecting an element with listview. The problem is that when I add the text content to the global variable, it says loading because I add too much text and Server error. Can’t load files…
I also did not use any google drive or firebase because I want the application to be used without internet.

Is there an easy way to add a lot of text? if so how? There are 18 of these global variables and they are all filled with lots of text.
How to make an application with a large amount of text, there are many examples on google play (can this be done in codes?)

Thanks for be interested
