title: How to train a tensorflow network using JNI on Android?
body: <p>Tensorflow is designed to compatible with mobile devices, and <a href="https://github.com/tensorflow/tensorflow/tree/master/tensorflow/examples/android" rel="noreferrer">there is an example of android app</a> using tensorflow. But I couldn't find any neural-network related functions in the source code. 
  And in <a href="https://www.tensorflow.org/versions/r0.11/api_docs/cc/index.html" rel="noreferrer">tensorflow C++ API</a>, I couldn't find any APIs for training a network?</p>
  
  <p>Is that I was too careless to find them or there is some other way to achieve this?</p>
  
  <p>Thanks.</p>
