2. public boolean shouldoverrideurlloading (WebView view, String URL) {
3. View.loadurl (URL);

[Java]View Plaincopy

2. public boolean onKeyDown (int keycode, keyevent event)
4. {//Check if the key event is the back key and if there's history
6. WebView Mywebview = (WebView) Findviewbyid (R.ID.WEBVIEW1);
8. if ((keycode = = keyevent.keycode_back) && mywebview.cangoback ())
10. {
12. Mywebview.goback ();
14. return true;
16. }//If It wasn ' t the back key or there's no Web page history, bubble up to the default//system behavior (probably exit The activity)

1. Window. Andorid.showtoast ("I Call the Android program");

Remember: in Andorid2.2 and Android2.3 inside the WebView JS call will cause a system crash VM aborting error This is the two version of the bug solved very troublesome until now, I still did not find a solution.
