Wiki update

Wonderful library!

Just wanted to point out that I tried following the Asset Usage wiki page:
https://github.com/StringCare/AndroidLibrary/wiki/Assets-Usage

And for me, retrieving the JSON objects (encrypted) from assets didn't work.
My app kept crashing.

Later I found that I adding:

aaptOptions {
noCompress "json"
}

only worked, if I deleted the app from my device first.
Like a reset. Otherwise the noCompress isn't applied by Android Studio.

Could you perhaps add a line at the top of the page, telling fellow developers that they might have to delete their app first.
Something like:

"Before start, you'll need to configure the extensions not to be compressed.
And also don't forget to delete the app from your device first, otherwise aaptOptions won't work:"
Trying to help future devs :)

Once again, thank you.
