Hi,
U can run your media files from the res/raw folder or from the /data folder or from the /sdcard.
To run media from /res/raw folder,
create folder raw under /res folder of ur package structure
copy media files into the /raw folder, say u copied song.mp3 to the res/raw folder
u can run the media file my specifying R.raw.song
To run media from /data folder
run the emulator, allow it to load-up
goto start menu and run the command prompt, go to tools directory in the android sdk
Lets say you have your unzipped android sdk at c:\android\android_sdk_windows_m5-rc20a
In the command prompt run command
cd c:\android\android_sdk_windows_m5-rc20a\tools
Now ur in the tools directory of the android sdk
Run command
adb push c:/song.mp3 /data/song.mp3
this copies song.mp3 file from C drive to the data folder of the emulator
u can run the media file my specifying path as /data/song.mp3
To run media from /sdcard, refer link below
