title: Difference between Argcis v10.2.8 and Argcis v100 (Android)
body: <p>I'm new to arcgis.<br/><br/>
  I'm trying to develop an android app based on argcis. When i use v10.2.8 as used in guide (<a href="https://developers.arcgis.com/android/10-2/guide/welcome-to-the-help-for-arcgis-runtime-sdk-for-android.htm" rel="nofollow noreferrer">https://developers.arcgis.com/android/10-2/guide/welcome-to-the-help-for-arcgis-runtime-sdk-for-android.htm</a>), there is no problem. Also, Apk size is small. But when i look samples in github page of esri (<a href="https://github.com/Esri/arcgis-runtime-samples-android" rel="nofollow noreferrer">https://github.com/Esri/arcgis-runtime-samples-android</a>), they used v100. When i use v100, apk size raised (~60 mb) and samples didn't work.<br/><br/>
  I didn't understand which version should be used and what are differences between them.<br/>
  <br/>
  I'm totally confused. <br/><br/>
  Thanks in advance.</p>
