Question

I am developing an android application and i need to read words from a file to create a Trie. Is there a way i can write the file to internal storage on install so that only my application can access it, or should i hard code the words. Any suggestions are appreciated

If the file isn’t going to change, you should put it in your assets directory. If it is going to change, you can copy it from your assets to internal storage and it’ll be private. External storage (often an SD card) is word-readable.
