  <p>All the above crash reports are from Android 2.3.3 - 2.3.7 versions. Not sure what is causing this.</p>
  
  <p>I searched other similar posts too but the answers were around a custom object that implements parcelable which I <em>do not</em> implement in my app.</p>
  
  <p>I am using the latest version of android support library and play-services in my app as given below:</p>
  
  <pre><code>compile 'com.android.support:cardview-v7:23.1.1'
  compile 'com.android.support:design:23.1.1'
  
  compile 'com.google.android.gms:play-services-analytics:8.4.0'
