body: <p>I have an app which use Apache POI. The Build is successfully but when I run the code there is an error (I use Android Studio 2.1) :</p>
  
  <pre><code>Execution failed for task ':app:transformClassesWithInstantRunForDebug'.

  <p>Here is my code :</p>
  
  <pre><code>package com.example.lionel.xls_test;

  <p>I think that i implemented all the .jar files of POI Apache, here the dependencies :</p>
  
  <pre><code>dependencies {
  compile fileTree(include: ['*.jar'], dir: 'libs')
  testCompile 'junit:junit:4.12'
  compile 'com.android.support:appcompat-v7:23.3.0'

  compile project(':poi-ooxml-3.14-20160307')
