@tatebn - Hi, I desperately needed this post! But as yours seems to be
an internal web view, mine is an external file on the SD-Card. I'm
trying to read it using this,
BufferedReader in = new BufferedReader(new FileReader("/sdcard/
TextFiles/post.txt"));
And I cannot further decide how to split the content into different
page views so that they can be added to the addView method. Let me
know if you have a solution or guide me elsewhere.
P.S. I'm new to Android.
