android layout support for all screen sizes with support to pre lollipop and above lollipop devices

This is my first android app, I am stuck on how to group layouts for small, medium and large screen sizes and also how to support pre lollipop devices and above lollipop devices?







whether the directory names listed above are correct? or else can someone tell me how to achieve this?

Answer Source

To give the support to all screen sizes using different layout folders you have to follow these folders structure.

res/layout/my_layout.xml             // layout for normal screen size ("default")
res/layout-small/my_layout.xml       // layout for small screen size
res/layout-large/my_layout.xml       // layout for large screen size
res/layout-xlarge/my_layout.xml      // layout for extra large screen size
res/layout-xlarge-land/my_layout.xml // layout for extra large in landscape orientation

And to give respective support enable in manifest.xml

<supports-screens android:smallScreens="true" 
      android:anyDensity="true" />

And for images respective to all screen resolutions use drawable folder structure:

res/drawable-mdpi/ic_launcher.png        // bitmap for medium density
 res/drawable-hdpi/ic_launcher.png        // bitmap for high density
 res/drawable-xhdpi/ic_launcher.png       // bitmap for extra high density

To give a support to before and after lollipop api. You have to decide minimum api level and max api level for app support.

Suppose for your app you want: Min. api level = 15 and Max. api level = 23

In Eclipse IDE: In Manifest.xml add

        android:targetSdkVersion="23" />

In AndroidStudio IDE: In build.gradle add

defaultConfig {
        minSdkVersion 15
        maxSdkVersion 23
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
