I have an application in which I need to implement image editing, which also includes pinch zooming. I am done with pinch zooming but I can test this only on device, not on emul
On a Mac running the latest version of AndroidStudio and a vanilla Nexus 5 API 24 emulator all you have to do is keep cmd (⌘) pressed.
The drag points will appear. After that just left click and drag anywhere on the screen!
