得到安卓浏览器历史记录

Tags: /Android/ Date Created:

I implemented content observer of history but it is behaving weird.For every change in history its onChange() function runs 3-5 times.

static class BrowserOberser extends ContentObserver {
   public BrowserOberser() {
       super(null);
   }
   @Override
   public boolean deliverSelfNotifications() {
       return true;
   }
   @Override
   public void onChange(boolean selfChange) {
       super.onChange(selfChange);
       Log.d("History", "onChange: " + selfChange);
   }
}

I also registered my observer using
BrowserOberser observer = new BrowserOberser();
getApplication().getContentResolver().registerContentObserver(Browser.BOOKMARKS_URI, true, observer );
and added required permissions in manifest.
The code works fine but onChange(); runs 3-5 times for each change in history
Can anyone help me out with a solution to this problem?
