When you pass between activities you can send info

Bundle bundle = new Bundle();
bundle.putStringArrayList("ArrayPics",myArrayofPics);         
Intent myIntent= new Intent(ActivityA.this, ActivityB.class);
myIntent.putExtras(bundle);
startActivity(myIntent);    

so your Activity B can receive the ArrayList

you can save data in Shared Preferences too and read in every Activity of your app

Shared Preferences

You can implement your own Contentprovider, see http://developer.android.com/reference/android/content/ContentProvider.html
