从网站查看大文本文件的最佳方法是什么？

Question

I tried webview.loadurl("www.blahblah.com/blah.txt") and it crashed after a couple of seconds. What else can I do?

I only want to view these .txt files from the web as fast and as stable as possible.

Also I came across asynctask while researching. What is it and can it help me with this?

Also how can I make them to a string if I want to display these text files as a listview item?

Asynctask is wrapper for a new thread that allow you to perform network tasks such as downloading. If you try to download on the UI thread, you will get a crash.

For the text file, download it to disc first, and then read it into memory and display it

StringBuilder txtString = new StringBuilder();

try {
    BufferedReader br = new BufferedReader(new FileReader(file));
    String textLine;

    while ((textLine = br.readLine()) != null) {
        txtString.append(line);
        txtString.append('\n');
    }
}
catch (IOException e) {
//error stuff
}
