My application uses nearly 100 MP3 files that can be played. Each mp3 is of 5MB size. I prefer to bundle the mp3 files along with the app. Keeping the application size in mind, I tried to reduce the bitrate of the mp3 files and use in the application. It addressed my problem of application size. But, obviously, the quality of sound of mp3 files is effected drastically.
I've been on my S4 for about a month, and have encountered an annoying problem.
I have about 10 gb of music in a folder called Music on my external SD card. I can see and pltany song via my files, or ES file Explorer. But none of my music apps (Samsung Music Player, Winamp, or Google Play Music) can see any songs that are in the Music folder.

I had an application which was working with android 4.2.
My application was reading a .csv file for searching information.
The application and its files were on the external SD card.

So I have moved all the files to the internal card.
So I have created a directory named "mydata" in /storage/emulated/0 which, I presume is the internal card.
C application is performing on the fly encryption & decryption but the cryptographic key is saved in the application binary, for more security it is desired to hide this key. One way is to put the key in smart card. Now can we load keys and certificates (using C application)from a smart-card or any other PKCS #11 token. I want to write and read encryption key from smart card.
