If you do not have an Android device or Nokia N900, you can still test if your mobile website works fine as Mozilla also provides Firefox for mobile to your desktop computer  for Windows, MAC OS X and Linux.

I’ve try it for Windows XP. There is no installer, after you download the file, simply extract the files in C:\Program Files for example, and then run C:\Program Files\fennec\fennec.exe to start Firefox 4 Mobile on your computer, it will open a 480×800 Window. Fennec is the codename for Firefox 4 Mobile.

    Oh, not this history. I want to talk about reading web cache, web history… read urls that firefox for android loaded.
    Sample code to read android default browser history:
    Cursor mCur = this.managedQuery(Browser.BOOKMARKS_URI,
    Browser.HISTORY_PROJECTION, null, null, null);
    if (mCur.moveToFirst() && mCur.getCount() > 0) {
    while (mCur.isAfterLast() == false) {
    Log.v(“titleIdx”, mCur
    Log.v(“urlIdx”, mCur

    Thanks you very much!
