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 emulator.
Is there any way for testing pinch zooming in android emulator, any shortcut key or any other way?
With a mouse:
Press and hold Ctrl and press and hold left mouse and while doing that move your mouse.
With a trackpad:
Press and hold Ctrl and press and hold your trackpad and move with a finger to the LEFT and RIGHT (not up and down).
Since ADT 17, it is possible to use a physical Android 4.0 device to send multitouch gestures to the emulator.See Android's instructions here.
Multi-Touch
The emulator supports multi-touch input, as an experimental feature in r17, using a tethered Android device running the SdkControllerMultitouch application. The application contains an activity that monitors touch inputs and sends them to the emulator. This requires an Android 4.0 or later system image.
The activity displays the content of the emulator screens to help with interactivity. It is recommended to enable "show touches" in the Developer section of the Settings on the emulator to see exactly where the touches are sent.
The SdkControllerSensor application source code is located in
$SDK/tools/apps/SdkControllerMultitouch/
But this is still a workaround since we need a real device. My advice would be to test your app directly on a real device as it's more robust, and even more performant.
I know it's late reply but this might save someones time.
Double-click and then hold down the second click and move the mouse up to zoom out or down to zoom in.
Hope this works!
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!
I know this is old but this might still help someone.
On mac:
To zoom in use double click
(on track pad)
To zoom out use Command + Shift + click (on track pad)
OK, I was experimenting a bit, and on the bluestacks android emulator, I've figured it out.
It is Ctrl+Mouse wheel.
Works for me, hope it helps you too.
There has been some progress in this field with android tools release 17 : you can use a device to control the emulator : http://developer.android.com/sdk/tools-notes.html.
Otherwise, it looks like testing on real device is just better for this case (and in general its also much faster).
For mac: Use the ⌥ Option key and then use your mouse or trackpad to pinch/zoom. This is working on the android studio emulator.
You can find all the shortcuts in the extended controls menu, by pressing the three dots on the menu and then navigating to "help".
Click 3 points (like preferences on emulator)
Settings
set param "Send keyboard shortcuts to" from "Virtual device" to "Emulator controls"
now gestures work perfect!
An Android Emulator doesn't support multi-touch you can't test it on emulators. Please use real-device for multitouch testing.
For recent developments in this regard read this - http://tools.android.com/tips/hardware-emulation
PinchZoom works on Multi-Touch.
If the device is supporting multi-touch then only your code will work else it wont work.
As the Android Emulators doesn't support multi-touch you can't test it on emulators.
Still new ADT has feature But I never tried this
CTRL + a click on left side of the view screen will zoom out.
Double click on a location will zoom in.
North and South -> Scroll wheel - up and down
West-> CTRL+Scroll up at left side of the screen
East-> CTRL+Scroll up at right side of the screen
On macbook with Android studio Bumblebee, I have to hold control first which lets the drag pointer to appear on the screen. Then all I need to do is double tap, hold the second tap, and drag to zoom-in/out.
As of March 1, 2016 for the Android Studio's emulator on Windows. The pinch key on the emulator is the Alt key. Hold down Alt and click and drag your mouse button.
The CTRL key might still work for you, but it doesn't work for me.
You can not able to test pinch zoom in Emulator. Please use Real device to test pinch zoom effect.
I have not try with youwave. May be you can able to test pinch in that environment.
Not sur but just try with it.
Enjoy Coding....

I've been doing development with Flutter. I was using a real hardware but wanted to use an emulator. I set it up but there's this issue.
I usually put my apps in virtual desktops and I switch between them with Ctrl+Meta+[arrow keys]. Each of them have a special purpose, usually desktop 1 is for browsing, desktop 2 is for development and desktop 4 is extra (for testing UI apps and emulator in this case).
However, after I launch Android emulator and switch to a different desktop, it results in the issue seen below:
The red area you see stays unresponsive for other apps such as browser, VSCode etc. (i.e. does not respond to clicks). That area is where the emulator is on Desktop 4. And it also keeps showing multitouch tool.
It's a bit annoying so I wanted to ask if anyone got this issue and if they have any solutions.
Thanks in advance.
Environment
Kubuntu 20.04
AMD Radeon R7 240/340
Solution 1
I have, somehow in a weird way, found a workaround for this issue.
After having this issue, go to the emulator window and press the magnifying glass with a plus button icon twice.
After that, it will drop that weird multitouch state and it won't bother you even as you switch desktop.
Rebooting computer will result in the same bug, however, you have to do it again.
Solution 2
Another method that works is to simply resize the window. If you have a device frame on your emulator, you can simply hold down the Meta key and hold right click and resize your window.
Solution 3
You can also maximize the window. If you have device frame around emulator window, you can press ALT+F3, which opens up window options menu, then click "Maximize". This will get rid of it.
I have Android Studio 3.1 and for some reason I am unable to scroll using the touchpad. I have to manually scroll by dragging the scroll bar on the right, and this can get very tedious and inconvenient if im working on a large project. I used to be able to two-finger scroll on previous versions of Android Studio but for some reason its just not working anymore. I have windows 10 if thats relevant. Any idea how I can fix this?
I had the same issue and found a solution by making a small change to a registry entry:
Open regedit.exe using run
Go to HKEY_CURRENT_USER -> SOFTWARE -> Elantech -> Smartpad
Change ScrollControl_Mode from 0 to 1
I found the answer here:
https://www.reddit.com/r/techsupport/comments/3lhmhq/win10_elan_touchpad_scrolling_issues/
Just go to File>Settings or Ctrl+Alt+S. Then Select Appearance in Appearance & Behavior menu. Now Scroll down to Windows option and Select the Smooth Scrolling checkbox. Below there is an image. This worked for me.

Two-finger scrolling problem generally occurs due to malfunctioning of touchpad drivers of windows 10.
Things you can try are:
Go to File>Settings or Ctrl+Alt+S. Then Select Appearance in Appearance & Behavior menu. Now Scroll down to Windows option and select the Smooth Scrolling checkbox
as suggested by #Nikhil
You have to update your touchpad drivers:
For updating driver:
Go to the Device Manager.
Expand "Mice and other pointing devices".
Right-click on your touchpad (probably Asus Support Device)
Properties.
Driver Tab.
Roll Back Driver.
Restart computer.
If it still doesn't work now try updating your touchpad driver again after rolling back.
If it still doesn't work try to uninstall your touchpad driver and reinstall it.
Important: Always Remember to restart your computer every time you make any change.
For me, the problem is often caused by other apps that are currently running. For example cmd or OneNote. After closing those scrolling works again.
I made android emulator for Nexus 10 using latest ADT(21) and SDK tools.
I know that in Android JellyBean 4.2 there's a new feature called DayDream. I want to access it in my Nexus10 Emulator I have. but don't know how.
i am not getting option Daydream inside Settings -> Display.
How can i enable and use it Inside Emulator?
Here's what i need to do:
1st Step: Launch the Settings app, scroll to the bottom, and tap About Phone.
2nd Step: In the middle of the screen is the listing for Android Version. Tap this item until you see a jelly bean appear on your screen. You can then tap and hold the giant jelly bean until your device vibrates. You should then see interactive beans floating all over your screen. And yes, you can fling them. Go ahead, try it.
3rd Step : After doing, this the BeanFlinger Daydream will be unlocked. You can find the Daydream option by going to Settings > Display > Daydream.
Hope it Will Help to all of the Users Facing this Same kind of Problem.
I too had the same problem, what I did was, previously, I had an emulator with 4.2.1 version. I changed it to 4.3, now its working for me.
I've searched around, and I just can't find certain keyboard shortcuts for the Android Emulator. Specifically,the equivalent of enter/click. I've found that fn+left arrow will move from highlighting one icon to another but no actions.
Just clicking the doesn't seem to have any effects on the Android emulator. (I'm running OS X Lion). Perhaps I need to configure something?
Any help is greatly appreciated!
I guess you don't have Keyboard support set to yes in you AVD (Hardware properties) and that's why your keyboard is not working.
Then most of the keys will work as expected.
I need to detect the double touch in emulator, while running my app. I used ScaleGestureDetector in my app. I need to check that in my emulator. In iPhone by pressing option, we can use the two finger touch. Is there any way to use the ScaleGestureDetector in emulator.

"After adding webcam support and sensor emulation, we are adding experimental support for Multi-Touch input through a tethered Android device." ....
But it looks like "This requires an Android 4.0 or later system image."
If you want to use two-finger pan you need to right click. On a Mac with a trackpad you would need to plug in a mouse or switch your secondary click to bottom corner. Then you can hold the command button. Otherwise hold the command button to see the finger indicators then click and drag to pinch/zoom
