My requirement is to open one app\'s Asset file from another app via content provider.(I am exposing that file with ContentProvider implementation)
I am able to open
Android tries to compress all assets, unless it's useless, like for *.mp3 files. I don't know if there is a complete list of filetypes that don't get compressed, but you should be fine if you just rename your files to .mp3 (the decision to compress or not is only based on the extension)
A little google search revealed:

If you have sufficient control over the build process, you can use the "-0" flag with zip or aapt to add the assets.
-0 specifies an additional extension for which such files will not be stored compressed in the .apk. An empty string means to not compress any files at all.
aapt is located in your
android-sdk\platforms\android-VERSION\tools
directory
from the link cited above:
static const char* kNoCompressExt[] = {
".jpg", ".jpeg", ".png", ".gif",
".wav", ".mp2", ".mp3", ".ogg", ".aac",
".mpg", ".mpeg", ".mid", ".midi", ".smf", ".jet",
".rtttl", ".imy", ".xmf", ".mp4", ".m4a",
".m4v", ".3gp", ".3gpp", ".3g2", ".3gpp2",
".amr", ".awb", ".wma", ".wmv"
};
