David - a few thoughts.
Each screen should be a new activity. The cost of creating a new
class is about 2 minutes and 4kb. The benefits are numerous.
1) Rely on xml layouts without custom if this screen than that or if
that screen then this
2) Avoid complex logic and bloated classes. In
A few thoughts;

You should not be spawning threads yourself, as it is against Android
best practices. Instead look at ASyncTask, which provides methods for

import android.text.Html;
(example turning raw html into a html enabled text view)
synopsis = (TextView) findViewById(R.id.synopsis);
5 minutes is excessive - but that is likely your device...
on my device running Fedora 64 it takes about 45 seconds before I see
the home screen, and my app starts up just after.
Typically I use the device manager to start the emulator before I
start debugging. this way it is ready and waiting
