I am trying to develop an application. So how can I use the main icon as a . GIF file? if it is possible. Then how?
According to Android docs you can't use .gif format for your launcher icon
Launcher icons should be 32-bit PNGs with an alpha channel for transparency. The finished launcher icon dimensions corresponding to a given generalized screen density are shown in the table below.
See this link for more informations on how to create a proper launcher image.
UPDATE:
In case that you want some more informations on this problem you can give a look at this forum. Spending a little more time on this I found that some people chose to use "dynamic launcher icons" changing the image programatically (details here). I do believe that this won't fix your problem, but this should provide some details on what's happening and maybe some starting point if you have to simulate somehow this behaviour.

This picture is a screenshot of an exiting app.
Uses color picker both of steches and round selection.
anyone help me how can I create a color picker like this one.
As i can see that you need recent color at bottom part.
Well there is many libs are available.
Here is one of them.
if you don't need same design of the lib. then setup code of lib in you system and customize the design as per your requirement.
For Simplicity you can use the existing library for color pickers, it's better not to reinvent the wheels and use the existing one.
Here is some top library for this.

I am currently developing an app which involves displaying a number from 1 to 60 in the notification bar. How do I implement this? At first I was thinking of
including all 60 number images within the app, but that seemed unintuitive as I would have to provide separate icons for different screen sizes. How can I generate these icons at runtime?
As long as you would need to use Drawable for notification large and small icons, you would obligatory change string value to drawable.
I think for this usecase, you can use this library: https://github.com/amulyakhare/TextDrawable
I haven't use that yet, but for Lollipop and higher version of Android notification bar, you may need to set transparent or no-color background for your chars.
Hope it help

I want to make an app that runs both in handset & Tablet as shown in figure:
This custom listview would contains around 200 items, its title & description can be loaded from SQLite
For loading 200 images should I use blob in SQLite or from the drawable folder,which would be a better approach ?
I read the android documentation Supporting Tablets & Handsets, it states that we should use fragments. So can anyone recommend me some tutorials to use fragments
that fits my question ?
I am new to it so any type of help is appreciated.
Thanks..
I think Master/Detail Flow is what you need. Luckily it's already built into Android Framework.
Creating a new project, when you reach this page, instead of selecting Blank Activity, select the third template, that is Master/Detail Flow.
The best way to learn it is to scrutinize the pre-written code in the template.
However, you can also get a grip on it with this tutorial.
About the second question, go for blob only if you have just a few pictures. But in case you have many pictures, decoding and encoding the pictures can be a pain in the back, so I recommend using simple Drawables.

this is definitely what you are looking for

Are you just trying to do something on the first launch and then never again? Or are you looking for that look and feel? If so, it's probably just images and such layed out. If you want to test the first launch, there's a few ways to do it. One of the easiest is to create an empty file in the shared preferences in your onCreate() method, then check to see if it is there. If it's not there, you do your on first launch action and then create the file afterwards.
