Let's discuss how you should handle loading. When content is loading. A blank or static screen can make it seem like an app is frozen, resulting in confusion and frustration and potentially causing people to leave your app. So you should provide loading an indication when something is loading. Let's go over some guidelines as usual. Make it clear when loading is occurring, at minimum, show an activity spinner that he knows something is happening.

Even better display explicit progress so the user can go watch how long they will be waiting. Educate or entertain people to mask loading time. Consider showing hints about gameplay, entertaining video sequences or interesting placeholder graphics, customized loading screens, all those standard progress indicators, usually okay. They can sometimes feel out of context. Consider designing a more immersive experience through custom animations and elements that match the style of your app or game. Show content as soon as possible.

Don't make people wait for content to load before seeing the screen they're expecting. Show the screen immediately, and use placeholder text graphics or animations to identify where content isn't available yet. replace these placeholder elements as the content loads. Whenever possible, pre load upcoming content in the background, such as while an animation is playing, or the user is navigating a level or menu. Facebook does really nicely with these animated dummy content blocks, which gets replaced with the actual content as soon as it becomes available.
