Answer 1

You can't do this unfortunately, the Drawables folder is a compile time resource that you cannot add to in run time. Otherwise, the R.java file would not be valid.

Answer 2

As the comments and answers mentioned you cannot add a file at runtime to your Drawable . As a matter of fact you cannot add any file to the bundle itself in runtime.

What you can do is add your file to the filesystem. If you want the file to be 'visible' only to your app use getFilesDir() . This returns a folder path present in your application sandbox. If it's meant to be a sort of temporary file and is less than 1MB use getCacheDir()

If the file is meant to be publicly visible use getExternalStoragePublicDirectory() but for this you would need WRITE_EXTERNAL_STORAGE permission.
