Try this to get the folder (and create it if it doesn't exist) and then use the f File var as you were doing in your code:

    File cacheDirectory;

    if ( android.os.Environment.getExternalStorageState().equals( android.os.Environment.MEDIA_MOUNTED ))
        cacheDirectory = new File( android.os.Environment.getExternalStorageDirectory(), "myFolder/" );
    else
        cacheDirectory = this.getCacheDir();

    if( !cacheDirectory.exists() )
        cacheDirectory.mkdirs();

    File f = new File( cacheDirectory, "my_file.jpg" );
