Well, to be honest you don't really need a splash screen.
What is taking so long is that you are loading the images in the same
thread as the UI thread.
This makes it hang while you load your bitmaps. I'm surprised you're not
getting an application not responding alert.
What I do in my game is load bitmaps in a background thread.
Simply show a progress dialog while the background thread loads the
bitmaps. Then tell the UI thread that all the resources are ready to go.
Something like:
void onCreate() {
Handler callbackHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
//all resources have been loaded...
}
}
class MyThread extends Thread {
Handler handler;
MyThread(Handler cbHandler) {
handler = cbHandler;
}
@Override
public void run() {
//load all the images here...
handler.sendEmptyMessage(); //let the UI thread know we're
done.
}
}
//show progress dialog here...
new MyThread(callbackHandler).start();
}
