title: Android: how can execute a chmod on rooted devides
body: <p>I would execute a command on my rooted Android 2.1 device</p>
  
  <blockquote>
    <p>String path = "/data/data/com.android.providers.settings/databases/settings.db";
    Runtime.getRuntime().exec("/system/bin/chmod -f 777 " + path);</p>

  <p>But this command does nothing on the targeted file. Any idea?</p>
