Just to be clear, the device isn't locked or anything and it works perfectly for my friend who has the same android studio version. The problem isn't with detecting the usb device (by the computer), I can access the device's content just perfectly so it connects correctly to my computer but not to android studio.
When I try to run an application, the usb device doesn't show amongst the options.
Can someone please help me with this issue, knowing that my android studio is updated.
UPDATE:
the devices I used are: Samsung J2 and J3
Have you installed Universal USB Driver, if no then you will not see any device to connect. you can also install individual company device driver.
just try Universal USB Driver to connect all devices
Download from here Universal USB Driver
Open the Device Manager window from the control panel in your computer. In the Others/Unknown Devices tab you would see an unknown android device. Right click on it and update the driver and re-run android studio.
Make sure usb debugging is on in your device.
In Android Studio
Tools->Android->Enable ADB Integration
Enable ADB Integration
Then run app
Hope it will solve the problem
Enable your ADB in your Android
-> First go to Settings->Developer Options
-> Then On or Enable your ADB Mode
Just a Restart of Android Studio worked for me.
In my case it happened because of non-interaction in Android_Studio for long.
Else, Check with Run -> Edit Configurations -> Target.
I have the same problem and I use Samsung too.
I fixed it by installing the device driver from Samsung which you can download from Samsung's website
Note
You need to enable ADB mode(Like the second comment)
You need to set Target in Android Studio to > Open Select Deployment Target Dialog
to set Target : Run > Edit
Configurations > Targets > Open Select Deployment Target Dialog
I've just installed VS2015 Community with Xamarin to develop some mobile apps. The problem is, I can't achieve debugging Android apps on any device. Android Device Monitor shows empty list. I tried connecting different phones, which I know are detected on my friend's PC. I can explore their files from windows explorer, from there computer sees them.
USB Debugging on the phone is turned on.
USB connection mode is set to camera, no change at all.
I have Google USB driver installed in Android SDK manager.
I tried adb kill-server, adb start-server. Nothing changed. adb devices
shows empty list.
This is device manager while Developers options are disabled on the phone.
And here with enabled Developers options
I also tried updateing driver to google usb driver, but windows said it's up to date.
You most likely did not grant access to the device. Try to go into the developer settings on the smartphone and revoke the USB debugging authorisation. Then connect the phone to the pc and and wait for a popup on the phone which you should accept. After accepting you should see your device with adb devices.
You can also try to set the connection mode to MTP (instead of the camera PTP).
Hope it helps!
Enable the device for development
Goto: Device > Settings > Developer Options > tick USB debugging
Sometimes just restarting Visual Studio might help
Try the this:
1 - Close Visual Studio
2 - connect your device
3 - Restart visual studio with the device already connected by usb (with the device options checked)
This just happened to me. And it seems setting the startup project to your Android project fixed it.
My understanding is that the Google USB Drivers from the Android SDK Manager only work for Google Nexus devices (at least according to https://developer.android.com/studio/run/win-usb.html); annoyingly enough, to use other kinds of devices you'll probably need to download vendor-specific drivers. For example, I definitely had to download Motorola's drivers to use my Droid for debugging purposes. Unfortunately, for whatever reason Windows wasn't able to automatically detect that that's what it needed to download, so I had to download them manually.
I had the same problem, using a Samsung Galaxy A5
Google Drivers Installed
Samsung Drivers Installed
Phone shows up in file explorer
Plugging the phone in while Visual Studio was opened resulted in a pop up asking for permission. After authorising, everything worked perfectly. I didn't have to go into the developer settings on the smartphone and revoke the USB debugging authorisation.
To preface, I had connected my phone (a blackberry which had Android and full Google Play Store access) via Android Studio before so I KNOW it's possible, but when I was trying to do it with Xamarin I was having issues, Visual Studio just wouldn't recognize my device.
Found the problem appears to be the USB cable I was using. When I standardly plug in the USB, blackberry gives me the option to just charge the phone, or to enable File Transferring. But the first cable I was using always just charged the phone and didn't give me options. I tried switching the usb cable and voila, I got the prompt, and I can see the device now in the Start Debugging dropdown. So it looks like there's charge-only usb cables as well as Data cables. Be sure you're using a Data cable else it won't be able to see your Device
I had the same issue after updating Visual Studio found that in recent versions is better if you open VS in administrator mode to properly work, this should fix the problem.
I had previously revoked debug auth on my phone, but my phone didn't prompt me to allow debugging on my PC when I connected it again. Ended-up restarting my LG V30 while connected to my PC and I was prompted to allow debugging.
After that, Visual Studio 2019 version 16.10.0 adds my phone to the device list.
Running on Windows 11. Visual Studio 2022. But, I don't think the versions are really relevant here - included for completeness.
Followed all instructions re enabling USB debugging from the device. Also, the USB Drivers for my Samsung device were successfully installed on the Windows machine.
I was running the Duet Display application as I had previously installed it for use with my iOS devices. This appears to have created a conflict when connecting the Android device, as the prompt related to Duet would appear but not the prompt to allow USB debugging from the computer along with the RSA thumbprint. Once I exited the Duet app from my system tray and reconnected the Android device I got the prompt and it immediately appeared in Visual Studio 2022.
Here's some things I check when having an issue with Android device not appearing:
Enable developer mode on the device from settings
Install (e.g. to windows) the manufacturer's* developer USB drivers for the device
Ensure the Minimum Android Version in the AndroidManifest.xml is lower or equal to your device
And as always, try a different lead and restart both PC and Device!!
*Manufacturer Android USB Development driver links I know of:
Sony | Samsung | Google/Nexus | Blackberry
I have just updated from VS2015 (14.0.25402.00 Update 3) to VS2017 (15.7.5).
Amongst other things, I had to migrate a .forms app from 2.3.x to 3.1.x...
As it (according to MS) now should be possible to install also the Xamarin integration software in parallel to older versions of VS, I first (for security reasons) wanted to leave my “old” .forms app under VS2015 and .forms 2.3x and start to update to .forms 3.x with VS2017.
First, everything looked good - I was able to open my “old” .forms 2.3.x project in VS2015 (what was not possible in the earlier migration from VS2013 to VS2015).
But, I was not able to bring my two dev mobiles (both Samsung Galaxy S7) to work under VS2015 again, although, they were showed to my dev-machine (windows explorer) correct.
After wasting about a full day (doing every suggested workaround, I found on the web), I gave up und started to migrate the .forms project under VS2017.
Under VS2017 both mobiles were showed immediately without any problems and I was able to debug to the device.
So.. it seems, as the installation of VS2017 (with Xamarin integration SW) has “destroyed” something in the VS2015 installation regarding the access to the mobile devices...
I wasn't getting the USB debugging prompt on the device to trust the PC it was connected to and it wasn't appearing in the drop down list of devices in Visual Studio or ADB. Tried many things but installing the USB driver for the device (in my case Sony Xperia XA1 from: https://developer.sony.com/develop/drivers/
After installing this device driver by right-clicking the ADB Interface device in Device Manager and choosing the downloaded driver it showed the prompt to allow the PC and now works fine. This was on Windows 8.1 . I don't remember having to do the same for my Windows 10 PC.
I tried all the options but the only way I got it working is to unplug the USB cable and connect it on a different USB port.
After downloading phone specific drivers and restarting computer / restarting visual studio etc etc. What fixed it for me was from developer options
Disable USB Debugging
Enable USB Debugging
This was on a Samsung Galaxy, looks like although it was saying USB debugging was enabled it was in fact not enabled until I retriggered it using the above method.
I searched for the answer before asking. They weren't satisfactory.
Environment and what I did so far:
My device is Xiaomi Redmi 2. I have enabled USB Debugging in my device.
My phone uses a Cyanogen mode with 5.1.1 installed ( Lollipop ) and not 4.4 ( Kit-Kat )
It is also connected as a media device as asked in an answer
I'm running android studio on Windows 8.1.
I don't want to change my OS if that's possible.
Minimum level it is set to be API Level 15 so all the devices with ICS will be supported.
Questions:
Do I need to install a driver and if yes, what driver do I need to install to make it work?
If I need it how do I use it?
Where do I get it from?
I have to mention that I am using this site for the first time so I might not know the best way to search.
Any tips on that?
It may just be that the MTP mode isn't supported. Try changing your usb connection to PTP in your device's usb connection settings.
Taken from the Android Studio User Guide.
If you are developing on Windows and would like to connect a device to test your applications, then you need to install the appropriate USB driver.
Find the appropriate driver for your device from the OEM drivers table.
Once you've downloaded your USB driver, follow the instructions to install or upgrade the driver, and whether you're installing for the first time or upgrading an existing driver.
Update your android studio and your android project :
Android Studio > SDK Manager (top right of the ide) > Launch Standalone SDK Manager > uncheck the 'installed' checkbox > make sure you have all the recommended updates, tools and apis installed to your development machine.
Update your android project manifest file (AndroidManifest.xml) on about line 20 usually to match the target SDK version you want to build for :
You have to install ADB USB driver manually
Try the below link
http://visualgdb.com/KB/usbdebug-manual/
Here is the problem. I want to run my Android Studio apps on my device (Samsung Galaxy Ace 2). But nothing works for me. Tell me what I've missed:
1) USB debugging is on
2) ADB driver is installed (in device manager i can see Android Composite ADB Interface)
3) ADB device list is still clear, even if i reset server(adb kill-server, adb start-server, adb devices - list of devices is clear)
4) in google usb driver directory, in android_winusb.inf file I added my device identificators
5) Android device manager still cannot connect to my device, showing this error when I reset it: "adb connection error an existing connection was forcibly closed by the remote host"
So I will be glad to hear any advices. Hope you'll help me
Did you try to configure the "Media Mode" in "Camera (PTP)" instead of "Media device (MTP)"? This is sometimes solving the issue. Its in the USB Computer Connection options of your Android device, you should see an "authorize" dialog then.
Update 04/2017: looks like it has been fixed in Android 7.1.2
I have done numerous ways of handling that issue. Finally it has worked! I am using LG Optimus II, but I believe the following steps are generic to other Android devices as well.
Step 1:
Make sure your device is enabled for development. If yes, go to Step 2, otherwise go to Settings > About phone and tap Build number seven times which is magic number :-).
Now Developer Options is available in the Settings.
Step 2:
Before you plug your device to PC, Go to Settings > Developer Options and select USB Connection method.
Step 3:
Plug the phone to the PC, you are given options for the USB Connection method, and please select Internet connection. Make sure you have connected to the Internet. By the way, I have changed MTP to PTP, it did not work for me. Therefore, I tried Internet connection mode, then it worked.
Step 4:
Run the app in the Android Studio, it will ask you to authorize the device for development, and select YES!.
Step 5:
Run the application via Android Studio and choose the device, not emulator, and BINGO! Welcome to Android development board.
Try swapping the USB port the cable is plugged into.
Sounds crazy but after 20 minutes of debugging this worked for me.
I also tried above solutions but got no luck. So here's what I did:
Download and install PdaNet+ to fix connection issues between my computer and android device
Enable USB debugging on my android device
Unplug the phone and plug it again after it's installed
Run my app and voila! My android device is now recognized by Android Studio
Although my computer could recognise my phone, I had to install the official drivers from the Samsung developer site to get adb/Android Studio to recognise it:
Samsung Android USB Driver for Windows
Click Revoke USB debugging authorization in Developer option and try it again.
Solution for those working with Huawei phones - You will get this error when ADB interface is not installed. Check if you have installed Huawei HiSuite. USB driver gets installed when you install HiSuite (I suppose this is true for most of the new phones that come with a Sync Software). If the ADB interface is installed on your computer you should see 'Android Composite ADB Interface' under Android Phone in your Device Manager as shown in this picture.
If you have Mi Device than you need to enable this two option after enabling Developer Mode.
USB Debugging (Enable = True)
Install via USB (Enable = True)
See this screenshot.
LG Optimus Zone 2 pp415 d\n connect in mtp, but does work in internet connection mode. Lost lots of time messing with it. There's no doc for this, but I'd suggest trying all 4 of the connection options. Only 1 that works for me is Internet Connection->Ethernet, then win 8 auto-detects a driver and installs it. In MTP mode despite all drivers being registered with device manager, adb doesn't pick it up.
I had the same problem. So here is what i did
reinstalled the device driver
changed the USB computer connection from MTP to Mass storage(UMS)
And it worked.
For me, I tried the above. Turns out my USB cable was bad. I changed the cable and then it worked.
I am sorry that i bothered you all. The problem was my device is cloned in different places in device manager. It was gone when I tried to update driver for my phone in "Other devices" list, and before i have been updating it in wrong sections. Thank you all.
In my case it was due to already running and hanged adb.exe on another user under my PC. I had two users on my PC, the second user had the adb.exe process hanged even when I tried to end the process. It worked with me after (End Process Tree) from the Task Manager.
Hope this will help someone with multiple users :)

In addition to the above configurations, I had to set deployment target to "Open Select Deployment Target Dialog", run once (choosing my device from the options listed), and from then on Android Studio was able to see my device even after changing the deployment setting back to "USB Device". My SWAG is that since Android Studio uses its own internal cache to find your device, it has to be initialized first.
I was on Samsung S8 and had same problem too. After I installed Samsung Kies, issues was resolved for me, as I believe it had updated the correct driver required for my Samsung S8.
On Windows 7 , the only thing that worked for me is this. Go to Device Manager -> Under Android Phone -> Right Click and select 'enable'
i had to install android studio in 2 machines and ive solved this problem intalling samnsung kies, i use 3 diferents samnsung devices (plus some other of my family and friends) and i dont have to strugle with the drivers, it works for me and i recomend it. hope it helps
For me, this ended up being because I had the wrong SDK level installed (new version of Android Studio installed the SDK for Android 10, whereas I have a device that runs only Android 8.1). While Android Studio would "recognize" the device and display a string in the "devices" menu instead of just saying that no device was connected, installing the right SDK level for my device ended up changing the string to something recognizable (my device's model name) and allowed me to actually run my app over ADB.
I had a big problem with my Samsung S10 Plus as it was not detecded by Android Studio on my Macbook even if I did all what is required to be detected, that is to say:
Enable developer mode (7 taps on Build version in Android settings)
Enable USB debugging
What I did is to start "Android File Transfer" on my Macbook and the magic happened. A popup appeared on my device asking if I want to authorize an USB access to it. I clicked "Yes, always" and now Android Studio can detect my device on my Mac :)
Change the connection method Build-In CD ROM it works for me
On HTC mini one 2, besides enabling the Developer Options, the following worked for me:
Go to More in Wireless & Networks
Mobile Network Sharing
In USB network setting
Select Internet pass-through
Eclipse can't detect my android device but it can run with the emulator. i have no problem with the android device setting since it work well in my old laptop.
any idea?
When you start the Device sometimes adb doesn't recognize it because it has already started. So, in that case you just need to reset adb from DDMS->Devices
Go to android-sdk/platform-tools/ via command promt...
write command.. adb devices (It will show the list of attached devices)
If its not display device number then look at the drivers of device on your system. And if display then just restart eclipse..
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"
Also, after installing the usb drivers you may need to set your Android device to developer mode and enable USB debugging on your device before it will be seen by adb or eclipse. From http://developer.android.com/tools/device.html
2.Enable USB debugging on your device. ◦On most devices running Android 3.2 or older, you can find the option under Settings > Applications > Development.
On Android 4.0 and newer, it's in Settings > Developer options.
Note: On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options.
In my case, i ran adb-devices and it did show my device and it was unauthorized on the PC I was using.
I went to developer tools and disabled and then enabled USB debugging. It then prompted me for authorization for that computer, and then it worked fine.
Hope this helps someone.
Try connecting using the command prompt ./adb connect 192.168.xxx.xxx:5555
If you are running Linux you will have to add your device to the /etc/udev/rules.d/51-android.rules file.
Have a look here: http://developer.android.com/tools/device.html . Its a document on using hardware devices.
haven't you enable 'debug mode' in your Android device?
If not, then please enable it first. Then follow the steps in this article.
This example use Lenovo P770 as a device.

-hope this is helpful, :).
just install any driver are any compatibility software provided by your device provider like Samsung provide kies,Htc provide Sync etc..
Either check check your sysytem or antivirus not block it.
