title: Qpython uknown RPC error
body: <p>I installed the QPython app on Android and executed a script name <strong>helloworld.py</strong>. It used androidhelper's method <strong>maketoast</strong> to show a message with the Android api.</p>
  
  <p>I tried writing the exact same script on another file but it is giving me the following error:</p>
  
  <blockquote>
    <p>com.googlecode.android_scripting.rpc.RpcError: Unknown RPC.</p>
  </blockquote>
  
  <p>Then I tried to modify <strong>helloworld.py</strong> and it's now giving me the above error.</p>
  
  <p>I searched all over the internet for this error but no solutions.</p>
  
  <p>By the way, I use a rooted Samsung Galaxy Tab 3 LITE T110N.</p>
  
  <p>I already tried using the <strong>android</strong> module, but it doesn't exist. So does <strong>sl4a</strong> doesn't exist.</p>
  
  <p>I use python 2.7.</p>
