Slider jumping fast at start

Hello
I'm using this slider to show some product images. Everything work good but when the app loads slider, slider jump fast between images and after 2 or 3 seconds it stops and start its usual activity.
Whats the problem here?
Here is my code :

` for(String name : url_maps.keySet()){
DefaultSliderView textSliderView = new DefaultSliderView(SecondActivity.this);

textSliderView
.image(url_maps.get(name))
.setScaleType(BaseSliderView.ScaleType.Fit)
.setOnSliderClickListener(SecondActivity.this);

textSliderView.bundle(new Bundle());
textSliderView.getBundle()
.putString("extra",name);
sliderShow.addSlider(textSliderView);
}
sliderShow.setDuration(50);
sliderShow.setPresetTransformer(SliderLayout.Transformer.ZoomOutSlide);
if(url_maps.size() <= 1)
sliderShow.stopAutoCycle();`
