Android emulator won't boot up

Question

I\'m trying to install android sdk and run my first application on my PC (Win7 64 bit). I followed instructions on http://developer.android.com from the beginning to http://

Answer 1

I run into this issue at least once every time I try to start a new project, maybe from projects sharing devices. In the following folder:

C:\Users\.android\avd\ (e.g. Nexus_5_API_23.avd)

I had to delete the following files pictured. I tried deleting the .qcow2 files as one user mentioned without luck. Notice all the files deleted are the newest modified files/folders (see the Date Modified column) that are not .ini or .conf files.

UPDATE: It seems if I delete just the snapshots directory (pictured above), that does the trick too.

Answer 2

I found it. In event viewer(Control Panel\All Control Panel Items\Administrative Tools\Event Viewer) clicked on Windows Log>Application on left menu and read error logs.

I googled dll file mentioned in log (aticfx32.dll) and found the dll file belongs to ATI graphic cards. My PC has an Intel graphic card. While searching for solution I also found this web page and applied solution they used. It works like a charm.

Steps:

1. Download your graphics card driver from intel's website
2. Extract the zip somewhere, Location does not matter
3. Go into Device Manager, (type Device Manager in the windows search bar)
4. Click Display Adapters and Intel HD Graphics.
5. Go to the tab labeled "Drivers"
6. Click "Update Drivers" and "Browse my computer for drivers"
7. Click "Let me pick from a list of drivers"
8. Click the Have Disk Button,
9. Navigate to where your extracted drivers are and go into the directory labeled "Graphics"
10. Select the file named "igdlh64.INF"
11. Click on the OK button and then click Next, the drivers should install
12. After that you need to reboot, and after rebooting your drivers should be updated

Answer 3

Have you installed any "Target" API?. Have you configured any "Virtual Device"?

The Log tells you that it can't find 'avdTest' device, it could be because you didn't configure it, or just, it's not present.

Try to setup a device at the Eclipse's "Virtual Device Manager", then, start the virtual device from this menu ( AVD devices -> Start... ) and if it works, then run your code on it.

I don't recommend you using command line for the first time. Also I recommend you trying with Android 2.3.3 (API 10) for first, because it takes less time time to start the emulator.

Answer 4

In my case I had to delete the file cache.img.qcow2 from my avd device folder (C:\Users\User_Name.android\avd\Device_Name.avd).

If problem remain same,

1. Hit drop down near pencil icon

Answer 6

I had the similar problem on OSX. My emulator works fine, but after some runs it won't start. I've solved that by :

1. Go to .android directory (in my case it was Users/<username>/.android
2. Go to avd folder
3. Find the emulator that won't start (directory name will be the same as emulator)
4. Remove all .img files from there. Do not remove .ini files.
5. Try to run the simulator again.
