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.

My emulator does not open up.
I have seen other questions in stackoverflow similar to my question, but I didn't get any help. Also I replaced my 1GB RAM with 2GB. But its still the same. The emulator does not show the home screen. I am using P4 3.0 GHZ processor. I also tried assigning 1024 mib to sd for a avd. But it is still the same.
I am using Android SDK 4.0 and Eclipse Juno.
Just wait, your machine isn't very much emulator friendly.
It only takes a bit longer the first time you run it.
it is a same problem that i have got.
but i solved it by,when i first start my emulator from AVD then i do not change it's scale,
then when it start as its default scale property then i close it and start one more time and scale it as i need it than it will work perfectly.
I tried a lot of options to get the emulator up and running. Cleaned/re-started/adb killstart and all this unfortunately did not work for me. I was trying with API level 20 (Android 4.4W ).
But, nothing helped. Hence i tried with API 17/18/19 ( Android 4.2,4.3 etc. ). Finally 4.3.1 and API 18 worked for me and my emulator started fine.
I am beginning android development using the latest versions of the android SDK and eclipse. I have followed the Hello Android Tutorial
and used every combination of targets available but the Emulator freezes on the load screen with the flashing "android" title.
I have checked the other related question and DID wait about 15 minutes. but still no change. Any help with this would be great. Thanks.
I had a similar issue, and still do sometimes today. Have you tried deleting the AVD and then re-creating it?
Also try changing some of the AVD's values, give it more ram, larger SD card. You can do this through Window > Android SDK and AVD Manager > Edit the AVD, and then add values / modify the SD card size.
EDIT: Also - just for reference, I have a Intel Core i7 with 16gb of RAM and AVD's STILL take forever to load.
EDIT: Another handy thing to know is that if you check the "Snapshot" option when editing the AVD, it will save the last state and load that instead of a full [slow] boot. Kind of like putting your computer to sleep.
Adding values / modify the SD card size may be better .
Try not to close the Android Emulator , to avoid re-open .
Yah android emulator takes time to start up, but it should start within 2-3 mins. Check your RAM and processor. The RAM must be atleast 1GB (preferably more) to speed up loading emulator.
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.
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.

The problem I am having is that when I run a FWVGA or WVGA sized emulator it sometimes runs at a MDPI size instead of HDPI. Here is an example with pictures
http://wonton-games.blogspot.com/2010/06/emulator-problems.html
I create the AVD with the proper hw.lcd.density setting and screen size and it randomly does this. There doesn't seem to be a pattern. I used to be able to just delete the AVD and create it over again and it would fix itself for a while but now it's getting worse.
Does anyone have any ideas cause I posted on the Android Developer forum but all I got was other people saying they get the same problem.
I get the same problem and find that it is often only solved by a reboot - of my PC rather than of the emulator. I've not needed to edit or recreate the AVD to solve the problem.
I think it might be related to unplugging my laptop from an external monitor and so changes the Windows display resolution but I haven't been able to regularly recreate the problem.
Since the same AVD image can work one day and not the next and the start working again after a reboot means that this must be a bug in the emulator rather than a problem with the configuration of the AVD.
Unfortunately, I don't know of any workarounds for the problem and as far as I can tell this hasn't been logged as a bug. (I haven't logged it myself since, as you say, it occurs randomly which makes it hard to fill in a decent bug report.)
