Android Studio provides us a way we can run over apps on our handset Android devices very easily and quickly. If you don’t have an Android device, don’t worry, Android Studio has an emulator for you, it creates virtual Android device, so you can run and text your apps without actually having an Android smartphone.
Android:name='android.hardware.camera' / android:name='android.permission.CAMERA' / This application works offline and you don’t need an internet connection. This is just an example from the manifest that is already written in our application, which gives camera permissions and in order to work you probably.

Download Intel Hardware Accelerated Execution Manager - Improve the speed of your Android emulations on Intel VT enabled systems with the help of this Android SDK hardware-assisted virtualization. Android:name='android.hardware.usb.accessory' / Set the minimum SDK version of the app to API level 12 if you are using 'android.hardware.usb' package or 10 if you are using the add-on library. For example: android:minSdkVersion='12' /. The hardware profiles provide preset configurations for emulating Clover devices in Android Studio. The current set of profiles is available in the clover-device-profiles.zip archive. The hardware profiles for the Clover Mini, Mini 2nd Gen, and Mobile require a specific DPI that may be overridden if you make changes to the profile. The emulator supports multi-touch input, as an experimental feature in r17, using a tethered Android device running the SdkControllerMultitouch appplication. The application contains an activity that monitor touch inputs and sends them to the emulator. This requires an Android 4.0 or later system image.
One of the strange but welcome spin offs from the Visual Studio 2015 launch is that the Microsoft Android emulator is now available as a standalone download. It works with Visual Studio and Eclipse.
The reasoning behind Microsoft creating and supplying an Android emulator isn't clear, but if you are using Android Studio it is well worth downloading and using if you are working under Windows. In many ways, it is everything that the emulator provided by Google should be and isn't. It is even better than the HAXM accelerated emulator provided by Intel.
There are many reasons why it is better. The first is that it runs under HyperV, which means you don't have to switch HyperV off to run it as you do with HAXM. It also works via a remote desktop, which HAXM based emulations don't.
If these two advantages aren't enough then the clincher is that it is fast and it has lots of extra, easy to use, features. For example, there is an easy to use control panel that gives you control over the accelerometer, location, network, battery state, camera and SD Card.
You can also use it to take screen shots.
While most of these things can be done using the standard emulator this one makes it easy. In addition you also get the ability to restore a backup by just dragging a zip, copy a local folder to the SD card and use a command line interface.
The fact that the emulator is part of Visual Studio was about the only thing off-putting about trying it and now you don't need to install Visual Studio. You can simply download and install the emulator on its own.
You will need a machine that supports HyperV, but that means most recent machines. If you have run anything else that makes use of HyperV then it should just work. You also don't have to install or configure HyperV to make it work. Simply download and use the installer. When it is all installed try the Nexus 7 emulator first as it has reasonably low resource requirements.
When you have the emulator installed there are still things that can go wrong. In particular the emulator makes use of a USB ADT connection to the IDE you are using. This means if the machine has a lot of USB devices already installed it might not work. I had to remove everything but the USB mouse and keyboard to make the emulator start on one particular machine.
If the emulator starts to load and stalls at 456 MBytes or thereabouts suspect that either your machine doesn't support HyperV or there is a USB clash.
Another problem is that, for some unknown reason, the installer fails to locate the Android SDK. If you run Android Studio and can't see the emulator listed in the drop-down list of devices then you need to edit the registry. Run Regedit and create or edit the key:
HKEY_LOCAL_MACHINESOFTWAREWow6432NodeAndroid SDK Tools
Notice the spaces in Android SDK Tools. Add the variable Path and set it to the directory where the SDK is stored. When you restart the emulator it should appear in the drop-down list and you should see lots of messages in logcat.
Once you can see the emulator listed as a device you can simply select it as the Run target, either in the dialog box that appears or in the Run Configuration for the app. Essentially, you use the emulator as if it was a real hardware device connected via USB.
You don't get as wide a range of emulator profiles, but those provided - Lollipop to Jellybean - are generally the useful ones. You also only get x86-based emulators, but this is true of HAXM too. The Google ARM emulators are so slow you really have to use a real device.
One final downside is that if you want to use the emulator beyond a 30-day trial period you have to log in with an Azure or Microsoft account. This is still free but you might not like it.
