In avd manager, when I try to create new avd, there was skin section. But after updating sdk, I cant see this section. How can I use my own screen size instead of existing screen size.
These are old and new appearance of new emulator screen.
old one
new one
If you are using the latest version of AVD Manager, you will find a new tab labelled ** Device Definition**.
Here select new Device, and then specify your Screen Size(in) and Resolution(px). You can also specify Size, Screen Ratio and Density besides other things.
Open the Android Virtual Device Manger go to Device Definition tab, create a new device.Then, Create a new emulator and choose your device from the drop down menu.
