Unrecognizable device on Android

I want to run my code on the phone. But Android does not recognize my device. I also did the connection assistant.
But the following error is given. please guide me.

Needed informations
Is ADB installed with Android Studio, or have you got external tool?
Is there a generic Android USB Device driver installed? It's provided with Android Studio, and should be obtained with SDK Tools.
Possible solution
If even AVD cannot be recognized, it could be fault of built-in ADB server. I would recommend installing ADB as an external program, e.g. from here (ClockworkMod page).
After installation, reboot PC and plug your phone in. If phone is visible, check for availability via adb devices command from CMD/terminal. Don't launch Android Studio yet, as it has its own instance of ADB server and you wouldn't be able to launch second one from console.
If phone is visible, use adb kill-server command to finish the console instance, and launch Android Studio. Everything should be detected, if not - you really should submit that bug...
If phone is not visible all the time after issuing adb devices, there is a chance that not all drivers are installed. Check ASUS for drivers, if they were installed automatically - install them manually.
Hope it will help!

Have a look at PdaNet+
Install both the desktop client and the corresponding android application from the google play store. Once you plug in your device it will prompt you that your device has been connected and adb should recognise it.

Trying to debug apps from eclipse on android

I am developing apps for android and I bought an bq Maxwell 2 Lite, and I wanted to test them in the device, but i can't seem to do it... can somebody help me with that?
The android version on the device is 4.1.1 and I have enabled debugging throw USB.
Thank you all for your time and thanks for all the help

So to test with any device you need
Install the driver for the device on your OS.
Enable USB debugging on your device.
Plug-in the device through an USB.
Run the app through the IDE and select the configured device to run the application
This should help you get started.

For using USB debugging in eclipse, make sure that you have all the drivers installed. Open sdk manager, under extras you can see Google USB drivers, make sure that this is downloaded.
If after this also it didn't work, go to device management if you are using windows and find your device. Right click on your device and update device drivers, update from my computer and give this folder sdk folder\sdk\extras\google\usb_driver. Set platform-tools folder in your path variables and run these commands:
adb kill-server
adb start-server
You can see list of attached devices using this command:
adb devices

My phone cannot be detected in eclipse to test run

Before asking my question, I have looked through a few threads that share the same problem as me and have tried all the given solution with no success. I am from Malaysia.
I cannot get my device to be detected to test my app on my phone. I have checked both the "Unknown sources" and "USB debugging" settings in my phone. I am using eclipse. But if I create a random virtual device, my app is able to run there.
Okay so I am using a Motorola Atrix 2. And I'm using Windows 8 Pro 64 bit
I have downloaded android SDK bundle from here : http://www.motorola.com/sites/motodev/us-en/motodev_lp.html
I have also tried downloading the latest driver with no success. I have also added this line in the manifest android:debuggable="true"
I have tried both as a mass storage device and a media transferring device.
I would appreciate any help a lot because as of now, I cannot progress further into developing an android app and that saddens me. :(
I have attached a picture of which my android phone should be detected in the window, but as you can see, none.

go to /your-android-sdk-directory/platform-tools using command prompt.
type
adb kill-server
adb start-server
adb devices
n see whether ur device is detected now or not...
Note: if you're using a Linux machine then put ./ before adb

Install proper drivers for your adb devices, from Android-SDK archive or Motorola site.
If you are on Windows machine, go to the device manager find your device, and select folder with drivers for it.

Open you windows os's explorer, have a look at the process, if there two or more process hold your adb, try to exits the process

Check that the android:minSdkVersion is lower or equal to the Version running on the phone. If it is higher it wont show on "Android Device Chooser"
Install and run programs/drivers with admin rights.

Have you installed Motorola Device Manager?
When debugging Samsung and HTC devices I got it to work by installing that kind of software (for syncing the devices to the computer).

Download from the following: ABD Universal Driver
and install it. Make sure you have your device plugged in before installing and make sure you are on USB debug mode on the phone settings.

why is my device not shown when I want to deploy the application?

I want to deploy my android application on samsung, my device is not shown in Android device chooser even Samsung kies is installed.I tries all my possibilities but it doesn't work 4 me. Can anybody help me Your help would be appreciated !!

Check If you have enable USB Debugging and Allow Mock Locations ON in your Device

Make sure In settings -> developers options-> enable USB Debugging
And in terminal, go to platform-tools where you installed android, then give command
1. adb kill-server then
2. adb start-server then
3. adb devices: it should display your device.

Adb can't find my device

I was developing an android application from Eclipse, connecting my Acer ICONIATAB A 500, with Android 3.0.1. And I did not have any problem.
Now I'm trying to developing the same application on Acer ICONIATAB A 501, with Android 3.2
and my ADB can't find the new device, while Windows can find it! I set in my tablet Debug USB option active, and I installed the appropriate driver on Windows.
I installed even the last Google USB driver (Rev. 7)
I tried to list the device find form adb with command
adb devices
from command line, but List of devices attached is empty.
What can i do?

execute these line
adb kill-server
adb start-server
if it is mobile device check that in settings, developers options , debugging mode is checked or not

You need to install LGUnitedMobileDriver package from the LG website, even though Windows 7 automatically installed USB drivers for the phone.

Try to update your Android-SDK on your computer (in Eclipse or whatever IDE you are using), this helped me solve a similar Problem.
