body: <p>How I can change some icons which are declared in strings.xml </p>
  
  <pre><code>&lt;resources&gt;
     ...
      &lt;string name="icon_info"&gt;&amp;#xf129;&lt;/string&gt;
      &lt;string name="icon_heart"&gt;&amp;#xf004;&lt;/string&gt;
     ....
  </code></pre>
  
  <p>and after I use them in some source files in java</p>
  
  <pre><code>Button txt=(Button) findViewById(R.id.infotxt); 
  Button txt1=(Button) findViewById(R.id.hearttxt); 
  
  Typeface webfont = Typeface.createFromAsset(getAssets(), "fontawesome-webfont.ttf");
  txt.setText(" " + getString(R.string.icon_info) + " ...");
  txt.setTypeface(webfont);
  txt1.setText(" " + getString(R.string.icon_heart) + " ...");
  txt1.setTypeface(webfont);
  </code></pre>
  
  <p>I would like to change these icons to other icons I have  on my computer.</p>
