I defined a splashscreen the following way:
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ExceptionHandler.register(this);
setFullscreen();
splashScreen();
}
private void splashScreen() {
runOnUiThread(new Runnable() {
@Override
public void run() {
setContentView(R.layout.splashscreen);
splash = (ImageView) findViewById(R.id.splashscreenLayer);
startSplashTime = new Date();
}
});
new LoadingThread().start();
}
private class LoadingThread extends Thread {
@Override
public void run() {
checkNetwork();
}
}
Somewhere at specific conditions in the checkNetwork() method, the stopSplash method is called:
public void stopSplash() {
Message msg = new Message();
msg.what = STOPSPLASH;
Date endSplashTime = new Date();
long time = endSplashTime.getTime() - startSplashTime.getTime();
System.out.println("Time Splashscreen was displayed: " + time);
if (time < SPLASH_MIN_TIME) {
long delay = SPLASH_MIN_TIME - time;
System.out.println("Delay Splashscreen for: " + delay);
try {
Thread.sleep(delay);
} catch (InterruptedException e) {
e.printStackTrace();
}
splashHandler.sendMessage(msg);
} else {
System.out.print("Show Splashscreen now");
splashHandler.sendMessage(msg);
}
}
private Handler splashHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case STOPSPLASH:
splash.setVisibility(View.GONE);
break;
}
super.handleMessage(msg);
}
};
The problem is, sometimes (maybe 1 of 10) if I started the app directly from Eclipse, the Splashscreen isn't showed, but instead just a black screen.
Other problem: if i restart the app, e.g. after onDestroy() was called after clicking the back button on the device, the Splashscreen is almost never shown.
Any hints why?
My assumption: could it be, that the LoadingThread starts "faster" than the Runnable, and so the network staff is done before the Splashscreen is set?
