title: Additional Android APIs not shown in Android SDK Manager
body: <p>I installed <strong>Android SDK Manager</strong> two months back. I got the <strong>Android 2.3.3 SDK</strong> installed, but I do not quite remember the steps I followed, because I am new to Android development. Now, when I open Android SDK manager, I see only the "<strong>SDK Platform Android 2.3.3</strong>". I cannot see any other API versions which I am interested in (eg. higer versions). However, I do not see any options for selecting any other API versions.  I have already tried the following:</p>
  
  <p>1) Tried to locate "<strong>Available Packages</strong>" option, but I cannot locate this option in Android SDK Manager.</p>
  
  <p>2) Tried <strong>Tools -> Options -> "force <a href="https://...sources" rel="nofollow noreferrer">https://...sources</a>"</strong>. After doing this, it connected to this URL but the View remains the same,i.e I cannot see a list of available packages that I can install. I have not given any proxy address in the boxes.</p>
  
  <p>3) I have run the Android SDK manager with administrator privilege.</p>
  
  <p>4) I am not running Android SDK manager from eclipse, i.e. I am running it directly. (at the time of writing I am downloading eclipse again because I had uninstalled it. So, I haven't tried opening Android SDK manager from eclipse).</p>
  
  <p>I am attaching the screen shot of the Android SDK manager. (with the version number of SDK manager in the About dialog box)</p>
