问题
I done a fade animation with three images displayed in splash screen.I got an output successfully.
But I got a two issue:
Time Loading:
- It tooks more time to load a splash screen.It needs to enter into the application as soon as possible.
App doesn't Close:
After entered into an Application.I am trying to close these app with the help of Back Button in emulator.But It never closes an
application.It stays in an application itself.In log cats,I seen the loop 1,2 and 3 continues again and again.I can't able to close my app.
If I am press the Home Button,It displays a home screen but again enter into an application automatically.
LogCat:
I am not getting any logcat error.But you can see that logcat readings always running.It never gets stop.The loop 1,2 and 3 continuously reading in logcat.For these it never closes an application.Then If I am press the home button,home screen would be displayed.But sometimes it automatically enter into these application.

Below I posted my entire core related to SplashActivity.

R.drawable.spl3 };
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_splash);
final Handler mHandler = new Handler();
// Create runnable for posting
final Runnable mUpdateResults = new Runnable() {
public void run() {
AnimateandSlideShow();
}
};
int delay = 1000; // delay for 1 sec.
int period = 8000; // repeat every 4 sec.
Timer timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
mHandler.post(mUpdateResults);
count = count + 1;
Log.v("test", count + "");
if (count >3) {
Intent i=new Intent(SplashActivity.this,HomeActivity.class);
startActivity(i);
count=0;
}
}
}, delay, period);
}
//

private void AnimateandSlideShow() {
slidingimage = (ImageView) findViewById(R.id.ImageView3_Left);
slidingimage.setImageResource(IMAGE_IDS[currentimageindex
% IMAGE_IDS.length]);
currentimageindex++;
Animation rotateimage = AnimationUtils.loadAnimation(this,
R.anim.custom_anim);
slidingimage.startAnimation(rotateimage);
// Log.v("test","animation slide");
