openRawResourceFd fails on android

Question

I'm writing my first Android application, and I'm trying to read a res/raw resource file.

The following code throws a FileNotFound Exception:

AssetFileDescriptor fd = res.openRawResourceFd(R.raw.myfile);

but this line of code works:

InputStream stream = res.openRawResource (R.raw.myfile);

I need the AssetFileDescriptor in order to determine the length of the file. Any ideas why it isn't working?

did you find any way to do this?? – Shridutt Kothari Jun 09 '15 at 16:02 — Shridutt Kothari, Jun 09 '15 at 16:02

You can do it this way:

FileDescriptor fd = getResources().openRawResourceFd(R.raw.rawResourceId).getFileDescriptor();

No try/catch block required.

This works;

AssetFileDescriptor afd = res.openRawResourceFd(R.raw.rawResourceId);

Move your myfile to asset folder and try this

try{
    AssetFileDescriptor descriptor = getAssets().openFd( "myfile" );
    FileDescriptor fd = descriptor.getFileDescriptor();
}
catch(Exception)
{

}

Or you can try to open a RAW file from the resources/raw foder with this code:

FileDescriptor fd = getResources().openRawResourceFd(R.raw.myfile).getFileDescriptor();

openRawResource returns Inputstream and not FileInputStream – ozmank Feb 11 '16 at 08:42
