Project Description:
I designed my app in one of the cloud based tool. Now the code is ready.

I want more coding or modification of code to meet following requirements:

1- Google licensing. Required codes to be integrated into source code (trail period). So that it can be licensed when uploaded on google play.
2- Encryption of contents of /assets/Docs folder (Cryptography), so that if someone get hand on my app and extract it, he/she should not be able to use my files for building his own. The format of the contents are HTML,
3- Add Search Function. When Menu Button (of the device) is tapped, a button to appear among other buttons and its functionality to open a page with search box. User type a word or short phrase to look up it through the contents of the app. Found word/s to be listed below search box. User tab one of them then he/she is taken to respective page. Of course, along with the found word, one line of the respective sentence to be displayed below the search box. (for further explanation, I am read to accommodate your skype address).
4- Fixing the problem of send email button. It gives errors. The activity has been created but it gives error.
