title: making adult content filter app in android
body: <p>i have made an browser in which it will not allow the user to see any adult content. i used only matcher and pattern something like this:</p>
  
  <pre><code>Matcher m = p.matcher(s);
  Pattern p = Pattern.compile("\\b" + Pattern.quote("word which you want to block") + "\\b");
  </code></pre>
  
  <p>my question is:</p>
  
  <p>Is it possible to filtering in whole android ? </p>
  
  <p>for ex.: can i make a service of content filter which will work in back of every browser in android??</p>
  
  <p>my idea is to get url from every browsers coz first i read whole contents of website and if my defined keywords will match with content then it will block the webpage otherwise it will not interrupt the user in surfing internet.</p>
