Hide Files Inside Image File on Android

 You can hide any file inside any image file by using your android device. Some of you may already know that this method is called as "Steganography". If not, take a look at the Introduction to Steganography, otherwise skip it.

INTRODUCTION TO STEGANOGRAPHY

Steganography is an art of hiding a file, message, audio, video, or image within another file, message, audio, video, or image. The word steganography comes from two greek words "steganos" (meaning: concealed) and "graphein" (meaning: writing).

The basic difference between cryptography and Steganography is that in cryptography only the message is hidden, but in Steganography, the message and the secret communication are hidden.

A lot of good steganographic tools are available for Windows, Mac, and Linux, but not that much for the Android operating system.
Now let's dive into the how-to guide...
