title: Fragment crashes with Parcel: unable to marshal value error when onPause method is called
body: <p>I have been developing android apps for a while now but only recently gotten into Fragments and hence I run into a lot of problems learning how to work with them. One of the activities in my applications has four different fragments, each of which displays a list of items to the user. Each fragment is created at first and is only shown once selected and hidden when another tab is selected. Once each of these fragments are created an ArrayList of JSONObjects is passed as an argument to the fragment as follows</p>
  
  <pre><code>            ft = fm.beginTransaction();
  
              if(currentFragment !=null){
                  ft.hide(currentFragment);
              }
              if(whereFragment !=null){
                  ft.show(whereFragment);
              }else{
                  if(mPlaceList.size()&gt;0){
  
                  Bundle bundle = new Bundle();
                  bundle.putSerializable("array", mPlaceList);
                  whereFragment = new WhereFragment();
                  whereFragment.setArguments(bundle);
                  ft.add(R.id.newpost_container,whereFragment, "whereFragment");
                  }
              }
              ft.commit();
              currentFragment = whereFragment;
  </code></pre>
  
  <p>The arraylist is received in the fragment and everything works just fine.</p>
  
  <pre><code>actList = (ArrayList&lt;JSONObject&gt;) getArguments().getSerializable("array");
  doingAdapter = new DoingAdapter(getActivity(), actList);
  actListView.setAdapter(doingAdapter);
  </code></pre>
  
  <p>There is a button in the parent activity that launches the device camera. Once that happens and the onPause method in the fragment is called the application crashes and I get this error in my Logcat</p>
  
  <p><strong>Logcat:</strong></p>

  <p>I have been looking around in stackoverflow and I do see some questions with issues similar to mine, however I can't seem to take anything from any of them that can help me with my situation. I do get the gist of the issue with the fragment trying to save its state and not being able to serialize my json objects but it would be great if someone could help me work with either Serializable or Parcelable interfaces to fix my issue, that would be great. Also I have implemented Serializable in both fragment and activity as it has been suggested by others.</p>
