Genymotion virtual device stuck on booting

The virtual device seems to be running but its status is stuck on booting so I can't install GApps (which I need to test some app) also it doesn't appear in the list of devices in Android studio.
I found this workaround to manually connect adb to Genymotion, but I still have an issue with GApps how can I install them?

I have had this same issue previously. However, what I did was that I closed Genymotion, reopen it and restarted the device.Then went to Android Studio and run the app. You should then see the device under 'Connected Devices'. You should be able to see your design on the emulated device.

I was having the same problem, what worked for me was running:
adb devices
If that doesn't work, try running
adb kill-server
adb start-server

Adb connection error eclipse on os x

Hello i am trying to run my android app on eclipse and i have this problem:
The connection to adb is down, and a severe error has occured.
You must restart adb and Eclipse.
Please ensure that adb is correctly located at '/Users/giannis/android-sdks/platform-tools/adb' and can be executed.
any idea about the problem?

Since adb is installed and seems to be working, Eclipse is probably having a problem finding or starting adb. First, check that Eclipse has the right location set for the sdk (Window->Preferences->Android or slightly different on Mac). I think it should based on the error message. Then, if you still can't run the app from Eclipse, try starting adb from the command line with adb start-server.
EDIT: If the app still won't run after doing the above, make sure adb is able to find your device or emulator. Start the emulator or connect your device, then run adb devices from the terminal. If your device or emulator is not listed, adb can't connect to it. If it is an actual device, make sure USB debugging under developer options in the device settings is enabled.

Failed to start monitoring and not run the program. Why?

I reinstalled Windows 7 last week and unzipped Eclipse and reinstalled the SDK again, but I didn't run the program in Eclipse. When I connect the Galaxy phone to my computer, Eclipse shows an error and frequently writes in the console tab Failed to start monitoring 0A3C202B1601A00A. After a while, Eclipse qill show an Android Device Chooser window. I can't select 0A3C202B1601A00A.
I use ADB and i write adb address and adb devices in cmd, cmd writes deamon not running.
When I disconnect the phone from my computer and I want to run the program with an emulator, the program won't run and when I write adb devices in cmd, cmd nothing written.
Why? Please help me :(

Kill the adb task via task manager. Then, type at the command prompt: adb devices
This should restart the adb daemon and all is well.

Re-install the windows driver for your galaxy phone. Its possible that it is corrupted. I had to re-install mine just to get the OS to detect my phone a while back.
Also check the USB debugging mode the phone is using. Sometimes the phone can go into a storage-only mode.

In my case I just had to wait for half an hour after which everything works.
But this was the first start up of my 'hello world' app on my Android phone.
The IDE ran on Ubuntu linux.

android: eclipse does not load emulator device

When I try to Run (or Debug) my project in eclipse, the AVD emulator emulator boots normally but eclipse doesn't recognise it. On DDMS, the Devices tab does not find the AVD emulator and thus I see no traffic in the LogCat.
On the other hand, when I plug my phone and choose Run (or Debug) project, eclipse connects to the phone and works just fine (I see it on DDMS on LogCat shows traffic). Any thoughts on this one?
I'm using Eclipse_Galileo_5.2 and Google APIs (API level 12, Platform 3.1). I was working with the same setup before the problem appeared without any problems.
I highly appreciate all the help...

Simply run from command line adb kill-server and then adb start-server. ADB will reattach to the running emulator and will be able to work with it. Do not exit the emulator as bashu suggests as the problem is likely to appear again if you have a slower computer.

Lots of time it happens to me also.
What i do is, I first Exit the Emulator. Then kill adb using
adb kill-server after that i clean the project.
and then adb start-server
and finally run the application and it works fine for me.
Thanks.

Eclipse's DDMS is not detecting device (Emulator)

I am using Ubuntu (Linux) machine. DDMS in my eclipse is not detecting Emulator (Gingerbread) as devices.
Gingerbread emulator is working fine. When I run "ddms" in cammand prompt, its working properly, it will launch ddms which will show emulator as device with running processes BUT when I try to do the same in Eclipse its not detecting.
Because of that I am not able to do debugging.
Please help.

you have to start the adb server to get the service of the emulator or any device, if you using ubuntu then you have to kill the adb server and start it again, then it will work fine
