title: APK is only updated if build from console, not from eclipse
body: <p>I am trying to develop a cocos2d android project.  Something odd is happening. Inside eclipse I edit the source files, however eclipse seems to not be compiling the changeds.  Here is a typical log:</p>
  
  <pre><code>[2016-05-29 16:26:28 - GameName] Android Launch!
  [2016-05-29 16:26:28 - GameName] adb is running normally.
  [2016-05-29 16:26:28 - GameName] Performing org.cocos2dx.cpp.AppActivity activity launch
  [2016-05-29 16:26:28 - GameName] Automatic Target Mode: using device '020772d4'
  [2016-05-29 16:26:28 - GameName] Uploading GameName.apk onto device '020772d4'
  [2016-05-29 16:26:29 - GameName] Installing GameName.apk...
  [2016-05-29 16:26:37 - GameName] Success!
  [2016-05-29 16:26:37 - GameName] Starting activity org.cocos2dx.cpp.AppActivity on device 020772d4
  [2016-05-29 16:26:38 - GameName] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.CompanyName.GameName/org.cocos2dx.cpp.AppActivity }
  </code></pre>
  
  <p>As you can see it is generating a new apk and putting it on the device, however if you edit anything in the project those edits aren't shown. However if you go into command prompt and do <code>cocos run ...</code> then it compiles and runs with the changes in your source code.</p>
  
  <p>I have cleaned, rebuilt, relinked etc etc in eclipse and it is still the same story, eclipse does not update the app with the new changes it stays the same.</p>
  
  <p>Am I doomed to compile everything from command prompt?</p>
  
  <p>Also: Eclipse isnt recognizing any errors in my code.</p>
