do this

File file = new File(Environment.getExternalStorageDirectory()+"/Reginfo/input/register.html");
    if (file.exists())
    {   
      index.loadUrl("file://"+Environment.getExternalStorageDirectory()+"/Reginfo/input/register.html");

dont forget to add permissions to menifest

You shouldn't hard code the directory of the sdcard like that. Its typically at /mnt/sdcard/ but this is never assured instead of this you can write it like this.

and before you load the file from sd-card you make ensure that sd-card is mounted.

You can use the following:

if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){
    Log.d(TAG, "No SDCARD");
} else {
    index.loadUrl("file://"+Environment.getExternalStorageDirectory()+"/Reginfo/input/register.html");
}
