Hi Dave,
Thanks for the info.
Finally I have decided to put all my audio data to SD card.
I can do this as suggested by you for a manual check.
*"adb push /path/on/workstation/video.mp4 /sdcard"*
This will work on my emulator.
If I want to do this for a real device than my code should first push all my
audio data in the user's SD card.
Can you please show me a way how to do this?
Is there any predefined folder like drawable/raw (Or some other like this)
which can directly put our data in sdcard instead of application's private
folder?
