I used to run my application in VIVO Y51L device. It's showing as No USB devices detected.
Developer options and USB debugging is ON, but it is still not detecting. What should I do??
This is probably due to improper driver installation or adb. Although this should not have happened if you had it working earlier re-installing the drivers should fix this. I'd recommend you to download and run the 15 second adb installer. It would install adb system-wide and also give you an option to re-install the required google drivers.
Installing them should fix this. You can verify that your device is connected by opening the command prompt and typing adb devices. It should kill the daemon and restart it. Once you switch back to Android Studio and run it. Your device should show up there.
Good Luck.
I am working in a native-script application, so I use Android Emulator for checking, I have mentioned below the version of Emulator.
The Internet is not connected in my emulator even signal of the WIFI also shows cross mark whenever I connect the internet connection from my mobile (Android Lenovo P2) through hot-spot.
The emphasized textInternet does connect in my Emulator whenever I connect internet via my ACT connection wifi through the router.
Emulator APK version: 26.
Emulator device: Nexus 5.
Note: My laptop connects the internet only problem in Emulator
Does anybody help me To do any setting has to be done in my Emulator to connect the internet when I connect through my mobile hot-spot?
This clearly indicates Android emulator doesn't recognize youe mobile network connected with your machine network configuration. I would recommend to try following actions to resolve this issue.
Open the AVD Manager and wipe the data of that emulator.
If you were working with wifi network and instantly switch with your mobile data may cause this problem. just try to restart the emulator and try.
Your Emulator may be pointed with older version of SDK, so you may want to uninstall Android Emulator and re-install it. Sometimes older SDK data causes the issue that you have encountered.
Reboot your machine then connect freshly with your mobile data started with emulator and check it out.
If above nothing works just uninstall AVD and re-install.
Look out this Reference link as well.
Please let me know the above solutions works for you! Cheers!!!
I have fixed the issue by adding this line in Androidmanifest.xml
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
I am unable to run the emulator in android studio. I received a "Your cpu does not support required features (VT-x or SVM)" message. Someone told me to try and do what this link states "http://www.howtogeek.com/213795/how-to-enable-intel-vt-x-in-your-computers-bios-or-uefi-firmware/" which led me to a video and I tried following those directions but was unable to because first, there was no HyperV feature in the Windows features section. Second, there was no UEFI Firmware settings icon when I went to advanced settings in set up. How can I proceed from here to enable the VT-x in order for me to be able to use the emulator in Android studios? Thank you so much!!
Okay your cpu does not support is not the same as cannot use emulator you just have to use one that runs x86 images which is in fact GenyMotion...
https://www.genymotion.com/
sign up for free account and when you download you want the full install package with virtualbox included.
and it does support instantrun just like the google android emulators do
You will also find the android studio genymotion plugin at the same site to download and use with android studiio
I downloaded the Suite for the phone, the Google USB drivers and the Phone's connection drivers. So far, the phone works perfectly with the PC but Eclipse still refuses to see the phone and Device Manager is convincing me that I have no hardware compatible with the Google USB drivers. Therefore the Google USB drivers are downloaded but not installed or assigned to any device. I followed every answer on stackoverflow that there is so far, but none have solved the problem.
First, set your device into USB / debug mode.
Second, after you connect your device to the USB make sure your drivers is installed properly.
And last verify that adb.exe can detect you device from cmd (if running in windows) ..(path to your SDK)\platform-tools\adb device
If last step fails, then re-install you device driver, it should be handled automatically by sony pc-companion for your xperia phone.
You also have to enable USB-Debugging in Settings->Developer Options on your phone.
I have the samsung galaxy tab, when I plug it into to eclipse to run and debug my apps. Eclipse doesn't recognize the device. When I try it with my friend's Droid 2 it still doesn't work. Can someone please help me?
If you are developing with Windows, you might need to install the USB driver for our device. For Windows 7, here's how you do it:
To install the Android USB driver on Windows 7 for your device:
Connect your Android-powered device to your computer's USB port.
Right-click on Computer from your desktop or Windows Explorer, and select Manage.
Select Devices in the left pane.
Locate and expand Other device in the right pane.
Right-click the device name (such as Nexus S) and select Update Driver Software. This will launch the Hardware Update Wizard.
Select Browse my computer for driver software and click Next.
Click Browse and locate the USB driver folder. (The Google USB Driver is located in \extras\google\usb_driver.)
Click Next to install the driver.
Check this link for more information if you need it.
Have you tried:
Settings -> Applications -> Development - Enable USB Debugging
In android 4.2.* The “Developer Options” menu item is gone!
Answer: The “Developer Options” menu item on 4.2.* is hidden.
Goto Settings -> About Phone.
Goto “Build Number” at the end of the Scroll list.
Tap on “Build Number” repeatedly (7 times). On your third tap you should see message indicating that you only have 4 more taps to go to ‘become a developer’.
Continue: 4 more taps.
Hooray, you are now a ‘Developer’, go back to the Setting page.
You should see Developer Option menu item in your setting list now.
Open Developer Options and check USB debugging > Ok
****it's work for me****

download the samsung software Kies .it detects samsung deivces
Go to http://developer.android.com/tools/device.html and follow up
this solution worked for me
In addition to Settings -> Applications -> Development - Enable USB Debugging, click on the following option:
Revoke USB debugging authorization
And then plug the device again.
Addition to Tor-Morten's answer: Only checking the Developer setting for USB debugging may not be enough. The USB connection setting (Android 4.4: Settings -> Storage -> Option Menu -> USB computer connection) needs to be checked for either "Media device" or "Camera" before it will be shown in Eclipse's Android Device Chooser window.
Maybe its a matter of how you plugged the device onto your computer. I'm using a mac and pluged the usb into one of the keyboard slots. It doesn't find anything even you've installed Kies with all its new drivers.
After plugging it directly into one of the slots at the computer the device has been recognized imediately.
Even it is a beginner mistake....maybe it helps :)
This is a fairly common problem. You basically don't have the drivers you need for USB debugging.
There are a few different ways I've had to obtain drivers for phones. The first way you should attempt is to go into the Android SDK and AVD manager and download the Google USB driver debug package.
This may or may not give you the driver you need. If it doesn't you will have to do one of two things. One, add the device details to the driver file you just downloaded. Generally these will be posted on forums/boards discussing your phone type. Secondly, you can download a different driver from another source like the phone manufacturer.
Make sure your account has admin privileges. I installed my Motorola drivers without elevating, and although the install ran smoothly it never associated them to the device. Once I ran as admin, worked like a charm.
Ι had the same problem:
While i had activated the debugging options on my phone (Samsung Galaxy S Duos Black), eclipse couldn't find the device because the usb drivers failed to download or something and so in the Device Manager (win7) i saw only Android and CSC something, all yellow and with no installed drivers.
I tried to download the Samsung drivers manually, but this failed to work.
What REALLY worked was downloading+installing Samsung Kies, connecting my device through usb and at first it failed again to put the drivers, then i disconnected the device, pressed some troubleshooting errors button that was on the main screen (NOT the lite version, the normal one), that took some time, re-connected the device and voila, the drivers were installed successfully and both the Device Manager and eclipse recognised the device.
If you are on Linux you can try on terminal the following steps. Don't forget to have your device plugged in. Use sudo if doest work.
adb kill-server
adb start-server
adb devices (see if device is recognized)
I had the same problem with my LG G3 phone.
I tried to re-install the driver as explained here: http://developer.android.com/tools/extras/oem-usb.html
Nothing helped. Fortunately on the very same page I have found the link to LG firmware site: http://www.lg.com/us/support/software-firmware
So I did the following:
Connect the phone to the PC using the USB cable
Uninstalled the Google's USB driver (My Computer->Management->Devices->Portable Devices->MyPhone: uninstall)
Download driver for my LG G3 phone (LG885) from the LG site
Install this driver
Got on the phone screen request to approve the new RCA key and allow debugging.
Try to Run an Android project in Eclipse.
PROBLEM SOLVED.
I Had the same problem.
I saw that the product was correctly defined under Device Manager, but Eclispe did not show the product in the target.
The easy way was to install Samsung Kies and to see that the following command:
...eclipse\adt-bundle-windows-x86_64\sdk\platform-toolsadb\adb device
gives me some output instead of only "List of devices attached".
once it recognizes the product, use "run configuration" choosing target "Active devices" under "Launch on all compatible devices/AVD's" radio button.
still, you don't get the product on the list as expected but it works.
Good Luck!
I had the same problem on windows with my samsung galaxy device .. installing samsung kies solved the problem for me.
I had loads of problem getting this to work when I switched to a new computer.
I downloaded and installed Kies, but Windows 7 still didn't recognize my device.
My problem was the proxy my company use, Kies tries to download USB drivers in the installation, but fails silently and finishes the installation.
You might have this problem if your USB Driver folder in the installation is empty (i.e C:\Program Files (x86)\Samsung\Kies\USB Driver).
Solution for me: install Kies without a proxy.
Unload EasyTether extension.
This worked for me - look at the part about unloading the EasyTether extension. adb not finding my device / phone (MacOS X) I was able to connect my samsung galaxy note 2 to macbook pro snow leopard.
Download new USB driver for samsung/pc connection here:
http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
After enabling developer mode and USB debugging of course.
The phone should ask to accept the pc location as secure after USB driver upgrade.
Installing KIES did not fix the problem on my Galaxy Note 3.
