Question

I have a 2 part splash screen that I’ve been trying to get to work on Android 2.2 (eclipse emulator) Everything works in 2.3 emulator. In 2.2 it works more often than not – sometimes goes to black screen – sometimes I need to restart the emulator. If I try to click the screen to cancel the splash and go right to the main activity, it goes to black screen and in the log I see:

                    }
                    Thread.sleep(100);
                    count++;
                }
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            return new Integer(0);
        }

        @Override
        protected void onPostExecute(Integer result) {
            if (splashCount == 0) {
                splashCount = 1;
                ivSplash.setBackgroundResource(R.drawable.splash2);
                splashDelay = new SplashScreenDelay().execute(splashTime); 
            }
            else 
                startActivity(new Intent(getApplicationContext(), MainActivity.class));
        }

        protected void onCancelled() {
            startActivity(new Intent(getApplicationContext(), MainActivity.class));
        }
    }
}

Any advice? What’s making the cancelling of the splash give a black screen?
I’ve read that “launch timeout has expired” error comes when the MainActivity has to wait too long, but if the splash works interrupted (more time) why should it fail when there is a cancel (less time)?

Thanks

An async task is not well suited for setting a timer on your splash screen. A more suitable method would be to use a Handler and sendDelayed to delay the splash screen.
