You have to add different folder for different layout in res folder --> hdpi,mdpi,ldpi and for large screens you xhdpi(for Tablet) and large-hdpi or xlarge (for NXzoom). Also set Images and text size different in different layout as per screensize...

This guy has some great blogs about how to handle multiple screen sizes in your android applications. They're titled Handling Multiple Screen Sizes and there are 5 parts:

Answer 4

All the answers above are great in there own means.Many times we're in scenario where our nested LinearLayout within RelativeLayout is hard to fit all the screens considering some complex layout line Tile

The above scenario can be solved by android's percent support library fitting all the screens.

Demo HERE

GitHub Project HERE

<android.support.percent.PercentRelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <TextView
        android:id="@+id/fifty_huntv"
        android:background="#ff7acfff"
        android:text="20% - 50%"
        android:textColor="@android:color/white"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_heightPercent="20%"
        app:layout_widthPercent="50%" />
    <TextView
        android:layout_toRightOf="@id/fifty_huntv"
        android:background="#ffff5566"
        android:text="80%-50%"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_heightPercent="80%"
        app:layout_widthPercent="50%"
        />
</android.support.percent.PercentRelativeLayout>

Hope anyone find it useful :-).

For Old day, we used to create different layout folder such as layout-small, layout-normal, layout-large, layout-xlarge for multiple screen. But that is a hell lot of work. So there is a new way to support multiple screen. Details are given below.

For Support Multiple Screen (All Mobiles and Tablets):

For Mobiles : We generally using different values folders for different dpi and inside that values folders only the “dimens.xml” file is different because when we are using different devices only the dimension is changed other than that all the parameters for example colors, strings, styles etc. are same. For values folders: There are total 4 values folders.

values                                    (For mdpi devices)
values-hdpi                               (For hdpi devices)
values-xhdpi                              (For xhdpi devices)
values-xxhdpi                             (For xxhdpi devices)

(here Inside each folder only dimens file is different so except dimens file, keep all other files only in values folder.)

For Tablets : We have to use sw (smallestWidth) concept. For example sw600dp means the system will use these resources only when the smallest dimension of available screen is at least 600dp. The device’s smallestWidth does not change when the screen’s orientation changes. Generally we create two folders inside res folder for tablets:

layout-sw600dp                       (For 7″ to 9″ Screen)
layout-sw720dp                       (For 10″ to above screen)

One last thing, Images for any device (Mobiles or Tablets) you have to create different drawable folders:

drawable-mdpi
drawable-hdpi
drawable-xhdpi
drawable-xxhdpi
