How can I reduce Android Emulator resource consumption?

I have tried looking at this SO post but I already have 16GB of RAM and I don't want to decrease AVD memory. I do not understand why the Android Emulator takes up so many resources (%25+ CPU, Almost 1GB of RAM) when running a simple app (Like this: Single Activity with a RecyclerView and its Adapter. That's it). Any help would be appreciated.
My fan is always on when using the Android Emulator in Android Studio.

This is normal for the Android Emulator. My numbers are the same.

This is a big pain for me and even bigger after upgrading the AndroidStudio version.
One alternative is to use an external Device for Debugging in place of an Emulator.

android studio emulator loading but not working

I have used Eclipse to write apps for android multiple times without issue but I am now trying the new Android Studio which I like but here is my problem.
When I run the app I pick my AVD and then tell it to start. The emulator starts loading and then says paired. Then it starts telling me to swipe up and left and right to display and remove cards. Then it says to put hand on screen to dim the screen, ok well I'm on a MacBook Pro so that don't work I swipe to get past that part sometime I can others I can't. Next it says to touch the clock and say some words which also can't do on my Mac, and that is where the emulator stay it never goes to a home screen and it does this no matter what AVD I choose. How can I get the Emulator to just plain open to the home screen like it should.
Thanks for any help.

In your AVD Manager, edit your AVD and make sure your Target is "Android L" and not "Android X.XW". The "W" stands for "wear" and that is causing your issue.

Alright I figured it out. I remember having a similar problem recently when I was taking an android development class for college using eclipse and sure enough that was it.
So here was the solution eclipse gave same problem. for some reason if you have caught exemptions such as hard coding a string etc. the emulator will not run till you ignore these exemptions or fix every last ! mark in your code. Once you do this the emulator will load and run properly.

I also had the same problem with my AVD. The Android Emulator window just used to pop us and the green bars flowed infinitely. After lots of trial and error I arrived at a solution for my problem. the problem was with the Heap size and the RAM size.
Initially the default heap size was 128 MB and RAM was 1563 , I just changed the heap size to 512 MB and reduced the RAM size( high RAM was making my PC run slow) also I enabled hardware acceleration. And Yipeee, it worked.

Avd not launching on the eclipse

I have created a avd for nokia x on my eclipse. And is successfully created but when I start it , it does not starts up. it shows that its launching with a progress bar but it does not launches and does not gives any error also. I have installed all required plugins

Please delete your current AVD and restart the Eclipse . Sometimes, some abnormal malfunctions may happen unknowingly...
I'm attaching a screen shot for you to create an AVD with all necessary details., please follow and create the new AVD. That should help you to proceed further.
on a sidenote - I believe you system has a minimum of 4GB RAM in order to see the AVD coming up faster. If the RAM is less, then it may take good amount of time to come up and show on the screen.
I believe you are also aware of the HAXM and Intel Virtualization technique to make the Emulator run faster. If any doubts...follow this link as well posted by me - HAXM guidelines

Android Emulator is not working

When i run the emulator is running up to the process big text android. After that is not responding. In Eclipse console showing text "Wait for Home" I tried re-install of android also
My System properties Microsoft Windows XP, 0.99GB of RAM
Any help me for this problem Advanced Thanks

The emulator takes a long time to load the first time, several minutes, and in this time only shows 'Android' in large text. Wait a couple of minutes and then you should be fine.

Make sure your SD card file is large enough. I've found the minimum Eclipse enforces (9MB) isn't enough for it to boot.
You may also have to use a different computer or upgrade your RAM. Modern phones have around 500MB RAM, so .99 GB maybe not be enough to go around for Eclipse, Windows XP, and the emulator.
As a last resort, you could reformat. I was having a similar problem and it worked after reformatting.

Don't rush to reinstall the SDK. Try creating a new AVD with the same API level that your original one had and run your app on that one. If that's OK just delete the original one as its image may be corrupted. You won't lose anything and it's not worth spending time on trying to fix it.
Edited:
The solution which worked for me is, when you get the message
Waiting for HOME ('android.process.acore') to be launched...
wait for few seconds and then right click on the project and click run as android application once again.

I once had similar problem. This solution worked for me. When I launch the emulator, I chose wipe user data option on the launch options window. Hope this help.

Is it just me...or is android honeycomb 3.0 emulator really slow?

Well? I've tried increasing the RAM size of the emulator to 1024 MB and there was little improvement on the speed, however, it's still unusable. It has the speed of a turtle.
Anyone got better ideas to make it faster? Is there something I'm not doing correctly?

Check out the android developer documentation regarding 3.0 emulator performance. Scroll down to About Emulator Performance.
Copied tip for convenience:
Tip: To improve the startup time for the emulator, enable snapshots for the AVD when you create it with the SDK and AVD Manager (there's a checkbox in the AVD creator to Enable snapshots). Then, start the AVD from the AVD manager and check Launch from snapshot and Save to snapshot. This way, when you close the emulator, a snapshot of the AVD state is saved and used to quickly relaunch the AVD next time. However, when you choose to save a snapshot, the emulator will be slow to close, so you might want to disable Save to snapshot after you've acquired an initial snapshot (after you close the AVD for the first time).

Seems like everything 3.0 and beyond is slow for me. Everything before that runs very fast in emulator for me. However, I have an Intel integrated graphics card in my laptop. When I turn 3D setting to "Application Settings," I get relatively decent performance from the emulator, at least when it starts up, but then when I try to start any app from the default main app menu (contacts, for example) I get launcher errors. That happens for me on 3.0, 3.1 and 3.2. The one thing I'm suspicious of is that I'm running 64-bit Java SDK. Seem to be a number of posts out there related to 64-bit, but mostly they seem to be point to using 64-bit SDK with 32-bit Eclipse or vice versa, but in my tests, I am not even running Eclipse, haven't even reinstalled the ADT yet, just the Android SDK and created a few emulator instances. Again, prior to 3.0 everything is fast. 3.0 and beyond not good, but A LOT better with graphics settings as I mentioned above. If I could get past the launcher issues, I think I might be all set. Oh, btw also, for 3.0 and beyond, I bumped the memory up to 1024. I've tried increasing the heap for apps to double the default (from 48 to 96) but that doesn't seem to have alleviated my launcher problems.

It is slow. You can try creating a new Emulator with a smaller resolution.

I remember someone at google I/O saying that the HoneyComb emulator will run really really slow due to hardware acceleration turned on.
The PC may use software rendering for OpenGL hence the bad performance. The almost everything you see on the HoneyComb screen is rendered using OpenGL ES.
