Hello all, Sorry for bringing up this topic again but I haven't figured out how to do it (yet). As mentioned I am trying to make a splash screen for an application. The reason I need the splash screen is my app is taking a long time to load. I want the splash screen to be displayed until the images and sounds are finished loading, and when the main menu is ready to be displayed I want the splash screen to go that very moment without any further delays. So, I am not sure what way to go with all this information to digest and not so sure which path to take or how each path works. Perhaps someone could give me some help in understanding the best solution for my use case and why it works? Thanks a lot, John Goche (here is what I've found so far...) ---------------------------------------------------------------------------------- http://stackoverflow.com/questions/3536590/android-splash-screen-loading-screen I've had a look at this example but it seems it just waits three seconds and then ditches the splash screen for the main application. In my case different phones will take different amount of time which I do not know. Basically I need to display the splash screen while the images and sounds load up. When done I need to display my application. http://www.androidpeople.com/android-loading-welcome-splash-spash-screen-example ---------------------------------------------------------------------------------- Then I found this post stating that an AsyncTask can be used: http://stackoverflow.com/questions/1596947/android-application-loading-screen http://developer.android.com/reference/android/os/AsyncTask.html ---------------------------------------------------------------------------------- Then I found the code at: http://www.barebonescoder.com/2010/04/a-simple-android-splash-screen/ public class SplashScreen extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.splash); Thread splashThread = new Thread() { @Override public void run() { try { int waited = 0; while (waited < 5000) { sleep(100); waited += 100; } } catch (InterruptedException e) { // do nothing } finally { finish(); Intent i = new Intent(); i.setClassName("com.testing.splashscreensample", "com.testing.splashscreensample.mainmenu"); startActivity(i); } } }; splashThread.start(); } } but I am not clear on what the code exactly does. Where does the InterruptedException arise from? What happens if it takes more than 5 seconds to load the screen? In that case finish() will be called and there will be a blank screen while the game menu screen loads? Can someone please explain to me the details of this code? Is an AsynchTask better? Then there is this post: http://stackoverflow.com/questions/1979524/android-splashscreen Is using an AsyncTask better? What is the purpose of the template parameters <String, Void, Object> in the AsyncTask? Then there is this site: http://jyro.blogspot.com/2009/11/android-asynctask-template.html and this site: http://android-developers.blogspot.com/2009/05/painless-threading.html I'm somewhat confused... not sure if someone on this list would be so kind so as to help me out in understanding the different elements involved in setting up an AsyncTask or any other good way to set up a postponment till stuff is loaded, Thanks again, John Goche -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
