Android studio before 2.2 version at the xml design screen there was a view like "Preview all screen sizes" (check the image) but I cannot find that in Android Studio 2.2 Beta 2.
My Android Studio version is:
Android Studio 2.2 Beta 2
Build #AI-145.3200535, built on August 18, 2016
JRE: 1.8.0_76-release-b03 amd64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Could you help me where is it, how can I open it?
On
While preview all screen sizes seems to be gone, it is possible in 2.3 to view more than one screen size at the same time.
Right-click on the activity_main.xml (or whichever xml file) tab, and from the pop-up menu select split-vertically or split-horizontally.
This will create a second xml tab that can use a different screen for design/text. This can be repeated for more tabs, and the tabs can be "torn off" to float separately.
On
The Previews are back!
Try this:
If you can't find the tab, try double-shift and search for "Layout Validation".

The option to preview all screen sizes is not available in Android Studio 2.2 Beta 2. However, you can resize the preview screen to see how your layout would look on different screen sizes, as shown in the attached gif.
