I'm an Android newbie trying to learn how to port one of my apps to the Android platform. I've been following this tutorial:
http://www.vogella.de/articles/Android/article.html#overview
I'm stuck unable to boot up the emulator :( When I tell it to start, it would just stick at the "Android" boot animation for hours on end. I searched online and found some pages talking about disabling the boot animation. I did so and tried again. There's no boot animation (just the word "Android" flashing), but it's still hours with no sign of booting. 'top' shows an app called 'emulator' using a lot of CPU.
Am I doing something wrong? My system is an AMD Athlon X2 dual-core QL-60, 1900 MHz with 3GB ram.
Thanks for any help you can offer.
I had this problem and fixed it by deleting the emulator and creating a new one.
In eclipse:
Menu Window -> Android SVK and AVD Manager
Select Virtual devices (should be selected already)
Select the emulator giving you problems
Click edit to see the setting and remember them, click cancel.
Click delete to delete the emulator.
CLick create to create a new one that is the same as the old one.
Click start.
It started in about 30 seconds after I did that.
Normally the emulator starts in about 2-3 minutes for me. Then it mysteriously stopped working. I was seeing boot animation for 30 minutes before I gave up.
Note #1: Doing this will wipe your user data.
Note #2: As mentioned else where, it's a good idea to check "Enabled" for the snapshot, this lets you do faster startup next time.
Note #3: Also my new emulator came up in chinese. That's kinda of weird :)
Android emulator release 9 has new "snapshot" feature. You can save state of emulator (make image of emulator) and avoid booting when you start the emulator.
I see a similar problem while attempting to run applications on an emulator while the emulator isn't started yet. I find that starting the emulator manually via the "Window > Android SDK and AVD Manager" will load in just a couple minutes or faster, as expected. After the emulator is started manually in this way, you can load applications into it without issue.
I faced same problem on my laptop using I5 8GB RAM. The only solution that worked for me was connecting the laptop charger when launching the emulator. May sound wierd but this always works for me.

I am developing an Android app in Android Studio. When I try to run it on an AVD, the AVD screen shows nothing.
The device frame is visible, but there is nothing inside it. The message "waiting for target device to come online" doesn't show up either.
Furthermore, I am unable to edit the graphics in the AVD settings. I have tried running the program both normally and from the AVD manager, but it doesn't work either way.
Other solutions which I have tried (and failed) are removing C:\Windows\System32\Wbem from the PATH environment variable, ending the ADB process in Task Manager, and wiping data from the AVD in AVD manager. Oh, and I even uninstalled and reinstalled Android Studio but it still doesn't work, even for a basic Hello World program. Any help would be greatly appreciated.

I faced this problem due to my ram several times and even after upgrading I had to make several changes. The best solution is to set up a new avd. use Nexus S, and a light image. Start with API 16 and when it works go ahead and create your desired AVD. Keep your eye on the pop up errors AVD shows like HAXM
It may seem silly but have you checked if the emulator is not locked?
Ok, when Emulator is not displaying anything and saying like, waiting for online,
after click on power button then what you have to do is Go to,
AVD Manager then in Actions section click on bottom triangle button and click on "Cold Boot Now" to make working your Emulator.
I'm new to android developing, and when I finally sit down to learn, my android emulator wouldn't run. Well, some button is tellimg me the AVD: Nexus_5_API_23_x86 is running, but I don't get any emulator screen popping up even after leaving my laptop in overnight.
it's the first time I'm running the emulator, and the emulator screen has never appeared before.
Also, I always get this message displayed:
C:\Users\HUBERT\Application\Local1\Android\sdk1\Tools\emulator.exe -netdelay none -netspeed full -avd Nexus_ 5_API_23_x86
Also, if I click to run an app, I get the device chooser pop up, I select the Nexus and hit OK, but nothing happens. I still don't get the emulator screen.
Please help
You need to use the adv manager to get something that will work on your laptop. On the second bar down, the one under your "file, edit, view bar..., select the AVD manager. It's the third icon from the "?" icon traveling left. Try x86 and arm setups to see what will work. remember that the initial load will take some time. 2-3 minutes with 4 gig of RAM. what OS and how much RAM do you have?
finally, I did it by unchecking the emulated performance from Use Host GPU to Store a snapshot for faster startup, and that worked fine..
. at least for now.
I also downgraded the API from API 23 to API 15. Everything now seems to be OK.
The genymotion emulator starts from AndroidStudio. It shows its white screen but never goes beyond that. It never comes to the home screen. Tried running the app. does not work. I have tried API 18 emulator. does not work. I have tried changing sdk path, setting android_home. does not work??
Did you checked logs for errors or possible explanation? Do you have both VirtualBox and Genymotion configured properly? It is hard to answer your question more accurately cause you did provide little information.
Going into my BIOS and enabling Intel Virtualization Technology under the CPU Options, and then going into GenyMotion and changing the device's # of virtual processors fix this issue for me.
Some time ago i also faced the same problem ... you can try above all suggestion but what worked for me is :-
Downloading Oracle VM VirtualBox
Here is the link , DOWNLOAD and install it.
http://www.oracle.com/us/technologies/virtualization/virtualbox/overview/index.html
I often have the same problem. If I delete the virtual device and then reinstall it, it usually fixes the problem for me.
To delete it, open the genymotion desktop application
Delete the device that's giving you the white screen - select the device and then click on the trash can icon
After it's deleted, reinstall the device - press add, search for the device, select it and press next twice
The device will be installed again, and it may start properly this time around.
I'm a newbie that needs some help on getting the AVD running with my app. I've been developing C code for decades, but I have to admit the Eclipse/AVD setup has me stumped! I'm following the 'HelloWorld' tutorials on the developer.android website (and some others) and everything seems to be working OK, up to the point where I try to run it on the AVD simulator. I'm not getting any warnings, the Eclipse build/run output window says that everything is installed OK and the AVD does startup and run. Eclipse says that my app is loading, but it never runs. All I get is the simulator window with "ANDROID" on the screen and the buttons on the right-hand side.
I've got Eclipse Indigo and r18 of the Android PlugIn (I tried to install Helios, but the Eclipse website directed me to Indigo!). Is Indigo OK for running the simulator, or do I specifically need Helios? I also have Java 1.7.
The API level I have installed is Level 15 (v4.xxx of Android, I think). Don't know if I need a lower version to get my tutorial app to run, but level 15 is the only one I can select when setting up a device in the AVD manager.
I've been trying to get this going for days, trying all sorts of switches and buttons, but to no avail. Before I start uninstalling everything and reinstalling, can anyone advise if there is anything I might be missing, or has tripped over this problem themselves and found a way around it? Something that always trips up new starters maybe? Or do I need to go back to scratch?
Any help would be much appreciated.
How long are you leaving your emulator running after you attempt to launch your application? The Android OS can take a long time to boot up in the emulator. If it's stuck on the "ANDROID" screen then you're either not waiting long enough or there's something wrong with your emulator. It should eventually boot into the normal Android lock screen or home screen just like a device.
You can launch your emulator ahead of attempting to run your app by opening the Android Virtual Device Manager (toolbar icon in Eclipse, if installed properly) and then selecting an emulator and clicking the "Start" button. If you don't have any emulators listed, then you need to create one by clicking the "New..." button.
I am having a problem in hadling the galaxy tablet emulator whenever I'll run my application and the tablet launcnh then it will not shown any option to open my appliction or goto the menu!

Android Galaxy Tab Emulator
edit after looking at picture: Wait--first of all. You know you have to drag that slider thing across the screen to get started, right? After that--
I'm not sure about that specific one, but I did notice some general weirdness with the Android emulators. I found a pattern that makes them work--be patient and deliberate.
First restart all your stuff--heck restart your computer to be safe.
Launch eclipse. Start a debug session with the emulator. wait. WAIT... wait... Might be 30 seconds, might be 3 minutes, who knows.
Eventually the emulator should come up and, behold, maybe it works!
If so--here's the trick--never ever shut it down. Leave it up the whole time you are debugging. It will load your app in seconds and run it like a champ. Shut it down and you will have to restart eclipse to get it to work correctly again.
Between the long wait time and that bug I've seen people extremely frustrated (including myself).
If this isn't your problem--sorry, worth a shot.
