Android level17
<p>I downloaded android4.2, using SDK Manager.
When I restart my eclipse, my sdk location is the same but don't work.
I am getting this error:</p>

<pre><code>This Android SDK requires Android Developer Toolkit version 21.0.0 or above.  C...rsion is 20.0.0.v201206242043-391819.  Please update ADT to the latest version.
</code></pre>

<p>I try to update my eclipse, but i am getting this error:</p>

<pre><code>'Contacting Software Sites' has encountered a problem. No repository found at jar:file: /Downloads/JsonEditorPlugin-0.9.4/plugins/json.editor.plugin_0.9.4.jar!/.
</code></pre>

<p>Did anyone faced this problem.</p>
