Android Studio AVD Emulator Chrome and Play Store missing

I am making my first developer steps on Android.
Trying my first test app on an Android Virtual Device (AVD), I noticed that the device has almost no software on it, there is no Play Store and no Chrome Browser. See Screenshot. I checked all settings up and down but found no way to tweak the basic OS software load. I tried several phone models and API levels, but had no luck.
How can I create a device providing software support similar to a physical device, I do specifically need an Internet browser.

Google Play System Images
When creating the emulator, you need to select and create a system image that contains the playstore.

Google Play service not working on my emulator

I am getting an error that google play services not installed in you device when I am trying to run my code on my android emulator. Although the code is woking fine on my physical android device.

You should use an emulator with google API like attached screenshot:
Those with (Google APIs) tag beside them have google play service installed.

Probably your device image does not come with Play Sotre services installed.
Create another device emulator with an image that the Play Sotre services are already installed. Those images will have a checked icon in Play Store column:

Use geny motion. Its much better than default emulators.
You can download one from here

How to install skype in Android Emulator?

I am new to android app development. I want to create an intent to launch Skype. In order to test this, I assume that the emulator must have Skype already installed.
I tried to launch the play store on the emulator to get the Skype App. But the Google Playstore, when launched on emulator it complains that there is no wifi or data connection.
How can I get the emulator to connect to the host wifi(Wifi which the laptop is connected to?)?
Is there a another way to get Skype app on emulator without playstore?
Thank you

Assuming that you're using the latest Android Studio and Emulator, you could get the Skype application APK file from other sites and drag it onto the emulator for it install the application.
However I do suggest as #CommonsWare stated, use a physical Android Device instead of an emulator as some (probably most) apps won't work correctly due to Google Play Services being missing. You could try the images in the Android SDK that contain part of the Google Play Services within them, it's worth a shot but not something to rely on for the long run.

Install applications from play store in android emulator

I installed Play Store in my android emualtor. for some reasons I can't download many applications to my Emulator, because when it says "your device isn't compatible with this version" or just not appearing when I'm searching it.
Is there any way to "disguise" my emulator as Nexus 5 so that many application won't block me from downloading it?

I suggest you use the perfect Android emulator called: Genymotion: http://www.genymotion.com/, and then take look at http://www.youtube.com/watch?v=zvTYDcYOFyw to set up the Google play service on it. It works perfectly, and I can have different devices to emulate and download what I want.

How to run Google Glass Project on emulator?

I don't have a google glass device. But I am very interested to do apps for Google Glass. I want to run a Hello World in Google Glass without the use of device.
I followed the tutorials for Google Glass. Then I found some sample projects of Google glass. Can Anyone tell me how to run a simple Google Glass Project on an emulator or without a device.
And can you tell, Is there any alternative way to test the Glass APK developed by us without device.

First you need to set up Glass On mobile or an Emulator in Web. Gooogle Glass is orignally a launcher over android you need to install the apks of that launcher.
Here you will find the APK's (however Camera for Glass never worked for me.)
Here is an Album showing you the process (on Nexus 7)
And This is the set of Demo's
After all set up you have to connect the android phone and then install the apk's using adb.
e.g.
adb install -r com.sample.packagee
after that you can launch the app through voice command or if it doesnot support voice trigger then launch it like
adb shell am start -n com.mikedg.android.glass.launchy/.MainActivity
I am writing down a wiki for the issues and the to do's Please check it here..

There are no simulators right now available to do perform testing without the device.
First :
You can try this https://github.com/zhuowei/Xenologer and install the apk on mobile device which is more or less similar to what you are looking for.
Second :
You can try thus but u have to build your application based on Mirror API http ://glasssim.com/ or
https ://developers.google.com/glass/tools-downloads/playground
Third to have your custom apk install :
https ://developers.google.com/glass/develop/gdk/quick-start#installing_the_samples
To display your hello world Try second option it should work. It will add your card in Glass Timeline.
Hope this answers your question.
Thanks

There is not an emulator for Glass at this time. Testing on Glass is an important part of a Glassware development life cycle as the user experience is completely different from what you can experience on a phone or an emulator.
Feel free to follow issue 253 on our issue tracker for updates as the GDK evolves.
