Cannot be root on Android Emulator

I'm currently trying to develop an application for Android devices on an Android Emulator. I installed Android 4.3 on a VMWare Workstation, on a Windows 10 OS.
I want to test the app I'm developping on the Android emulator, so I have to create a bridge connection between my phyisical computer where I develop the aps, and the emulator, where I can test it. But when I try to create this bridge, I have to change settings and to be root of the emulator. When I try to do a 'su' command, I have the following error :
'su : uid 10000 not allowed to su'
I tried to follow this tutorial to give me the root acces of the emulator, but it didn't worked for me. The best answer is to execute this commands :
adb shell mount -o rw,remount -t yaffs2 /dev/block/mtdblock03 /system
adb push su /system/xbin/su
adb shell chmod 06755 /system
adb shell chmod 06755 /system/xbin/su
How to get root access on Android emulator?
More over, When I did the installation of the Android Emulator, I've done the installation specifying the read-write option.
It is not working for me, because when I try the first row, I obtain this message :
ADB error : 'device not found'
Such as it is described in this link :
How to fix: Error device not found with ADB.exe
But the answer exists for a phone, and not for an emulator. Do you know how to fix it ? How can I be root, and how can I found the 'device not found' ?
Here are the different parameters of the VM

su stands for super users which is available only on rooted device. it is more like using android application with administrator privilege.Try using BLuestacks rooted version.

No active compatible device found to running android application

I've fully searched this site in order to solve my problem without any success.
My device is Sony Xperia Go (ST27i)
When I want to run my android application in Eclipse, I get this error:
No active compatible AVD's or devices found. Relaunch this
configuration after connecting a device or starting an AVD.
But I can see my device name in "device list" linked to USB ports.
Can you please help me about this problem?
Thank you.

see the
<uses-sdk
android:minSdkVersion="see here"
android:targetSdkVersion="see here" />
for compatibility in your manifest

Can you connect to your device? Try this from the command line:
adb shell
If this fails try this as root:
killall adb
adb shell

For future readers may have this problem:
I've installed Sony PC Companion and now I can use my phone in order to test the application.

Android Device Not Detecting In Eclipse

I am trying to run my application on my Device from the Eclipse In windows.But my device is not detecting there in the eclipse.
My device driver is updated. In My device, I turned on "USB debugging mode" in Settings->Application->Development and also "Allow installation of non-market Applications" in Settings->Application->Development. And in Eclipse Target tab, selected "Always prompt to select device". My ProjectBuildTarget is not newer than my device's version. And tried adb kill-server also.
When i run adb devices it shows nothing in my command prompt.
How do I get Eclipse to load my app to my phone instead of my AVD?
When i tried it in my Mac machine It works perfectly..
Any solutions? Please suggest me..

Please try the following:
Go to settings in your phone
Go to storage menu
Select connect as MTP
Worked for me!

If you are using a MAC OS.... no need to install the Driver
But for Windows, try this http://developer.android.com/training/basics/firstapp/running-app.html#RealDevice

Debugging to phone
Please see the link above, the process is defined there from google.

close you AVD if its running, then re-plug your Mobile device, check in your phone USB debugging notification should come.

try deleting your AVD and leave your phone connected, then restart your IDE. Make sure you've downloaded the OEM USB drivers. If it still doesn't appear on the list, hit refresh then just run your app.

Android adb unable connect with ip address

I have installed android operating system in Oracle Virtual box successfully.

Finally, I solved my problem. This was my solution:
In the emulator press the CTRL + Home keys and press Devices > Network Adapters.
See the menu, select Network and select Bridged Adapter.
Press CTRL + ALT + F1 in the emulator to open the Android terminal and type the following command:
netcfg
Press CTRL + ALT + F7 to see the Graphical View.
Restart the emulator.
Use the found IP in the command:
adb connect <IP address>

At first enable adb over tcpip in the Android VM Terminal Emulator.
Type the command #
adb tcpip 5555
Then to connect via adb from a command line
Type the command #
adb connect 219.91.220.142
