Hi I'm new to android world.Iam working on an application that supports multiple screen sizes i did as explained here http://developer.android.com/guide/practices/screens_support.html#screen-independence . I didn't create different xmls for each screen size. But when I tested it on android 3 emulator it appears in small part of the screen.
So I think that the size specified for my application on the emulator is small so my widgets are not filling the whole screen as I want. Can I control that size of my application on the emulator?
See this question...How do I make my android apps fill the screen on Honeycomb?
Also, to avoid compatibility mode when running on Honeycomb, set targetSdkVersion to 11 or higher (as described at http://geekyouup.blogspot.com/2011/05/supporting-honeycomb-pt1.html).

I am assuming you want to support multiple screen sizes for your app. You can refer to this guide from Android Developers. Tl;dr you should make your layouts as flexible as possible. That includes but not limited to
Use ConstraintLayout to define the percentage of screen covered by a component, ratio of sizes etc etc
Avoid using hardcoded values(like layout_width="100dp" etc)
Also for a tablet, you must design an alternative layout which can take advantage of the larger screen in landscape mode
I am developing a native Android application, how to maintain same design, font size, layout style in all android device including tablet also.
Both devices have different resolution, because of which the UI seemed different in two different devices. In Android Studio layout preview change the device size and resolution to see how your app looks on different screen sizes and resolutions.
I have two sizes of 5.1 inches, a 4-inch for 480x800.
When I design in 5.1 screen and run with 4 inch screen, I have some trouble that some button missed position on screen.
I designed by layout.
Android runs on a variety of devices that offer different screen sizes
and densities. For applications, the Android system provides a
consistent development environment across devices and handles most of
the work to adjust each application's user interface to the screen on
which it is displayed.

Place your view inside a <ScrollView>. Doing so will mean users with smaller devices will be able to scroll the view if it is too large.
So I'm working on scaling my application to different screen sizes. Right now Its optimized for a 10.1 inch screen but I'm working to get it to run on the kindle fire which has a 7 inch screen. I'm only using relative layouts. As of now my background scales perfectly but the image buttons ontop of the background don't scale and I was wondering if there was a reason for this. Also I use margins to adjust the positions of my buttons, is this okay for scaling sizes?
to support application on different screen refer the following link
http://developer.android.com/guide/practices/screens_support.html
and to scale image button use nine patch images they scale well.
Also I use margins to adjust the positions of my buttons, is this okay for scaling sizes?
yes it okay.
You should always define in your manifest because the default values can change from one version to another.
But if you want to support xlarge screens then you're stuck because this attribute was introduced in API level 9 (android 2.3). You have to create two different APKs, one for android versions >= 2.3 and the other for the older ones.
Since it's a common issue, android provides a nice way to publish only one application on the market even if you use multiple APKs.
I am quite new to Android Development. I am developing an application that should run on Android-based phones as well as on Android-based Tablets. My Question is that how to support multiple screens. I have developed a simple list-view application that I am testing on my Galaxy Tab but it is appearing quite smaller on the screen and not coming as a full-screen. I have tried making changes in the manifest file and declared minSdkVersion as 7.. Any advices or examples would be appreciated????
The Supporting Multiple Screens section of the SDK docs should help you out. Have you looked at it?
Pay special attention to the Best Practices section and remember to use wrap_content, fill_parent, or the dp unit for layout dimensions in your views.
