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?
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.
