I like to start my app directly on Samsung S7 with AndroidStudio.
I have already enabled debugging mode in the developer option by tapping 7 times on build number, but still I don't see the device when starting the app and getting the "Select Deployment Target" Dialog.
What else do I have to do ?
In developer options at bottom of setings menu, ensure USB debugging is ticked. Then start again, restart windows and S7 to make sure and try again. With one of my devices, tapping seven times enabled developer mode, but the debugging options was not selected by default and had to be manually selected from developer options after they were enabled.
Install necessary drivers from this site. Then connect your device with debugging enabled, your device will prompt a dialog for permission, click ok.
If you are using windows, i have sometimes needed to "reconnect" the device. Particularly when switching between the device and emulator.
To do that, find the folder in the sdk that you have downloaded for adb.exe
In that folder, start up a command prompt and try "adb reconnect". This usually works for me. Sometimes, I have also had to revoke the debugging permissions and then reenable them from the developer settings on the phone...
Note that this S7 Is the most problematic phone I have with this issue. I have about 6 other development phones, and this is the worst for connection issues. Otherwise, I think the phone is great.
Suddenly my Android Studio stopped detecting all my devices, none of them is working. It happen from one execution to another. I've changed a few lines of code (1 min maybe?), hit run (instant run) and then I missed all my devices.
I'm using a Mac and as devices: Nexus 5x, Galaxy s6 and Oneplus One. What can be happening? I've checked previous questions here and tried all this:
Run configurations: no matter if I chose usb device or show the window, it does not work.
Tools > Android > Enable ADB integration: didn't help
Command line adb devices does not detect any either.
I've revoked and granted again USB authorizations. Still not working.
I've tried other apps I have, none work.
Restarted phones
Restarted android studio
Restarted computer
(Note: if I start an emulator it works, but I'd prefer to use physical device since I have to scan real barcodes)
Thanks a lot in advance.
On Lollipop 5.1
Go to About Phone
Click 7 times on Build Number. Now Developer options are enabled
Go back and Click Developer options
Enable USB debugging under Debugging.
Well, I've fixed. The problem in case any faces the same was a Stetho (http://facebook.github.io/stetho/) tab in chrome, the one you open by typing: chrome://inspect/#devices not sure about the reason because it's been open for 2 days now, but it was the cause, once I closed it, it worked.
Found this unaccepted answer here: macbook adb cannot open interface That for sure should be accepted.
EDIT: I've been able to replicate the problem. It happens when you have the devices tab open and try to run a second app that has stetho configured.
It happens if your device drivers not installed Please do this.
In Case of PC
Right click my computer select manage select device manager from left panel if your phone drivers not installed there will be yellow alert on driver right click on it select update driver software then select search automatically for update driver software.
Other
Please install the missing drivers of your phone.
I had the same problem . What I've done to solve it going to Setting >> Additional Setting >> Developer Option
Now select:
Developer option on
USB debugging on
Install via USB on
USB setting security on
Verify apps over USB
OK, what finally worked for me was to go into Settings\Developer options\Select USB Configuration and change it to PTP or MIDI....either one of those worked for me and all of the sudden my phone showed up and I was able to see and run my test app on my android phone.
This woorked for me
Go To Settings
Developer Options
Enable USB Debugging
Enable Verify Apps over USB
Select USB Configuration: Choose MIDI
I hope it also works for you
I tried to play Android Studio 2.0 with my mobile without success, what I did are:
In my mobile, Apps/gear icon/Settings/SYSTEM/{} Developer options/ Android debugging/, enable the Android Debug Bridge(adb) interface (set tick).
After plug in my mobile to my PC with a USB cable, I found A0001 in my Computer folder. Within A0001, I can see the files in my mobile.
In my PC, run Android Studio/bin/studio.exe, "Select Deployment Target" window shows with message "No USB devices or running emulators detected"
I have tried two different USB drivers but got no lucky.
Perhaps I should tell Android Studio where is my USB driver? But, how?
Can you help?
I had the same problem too and I managed to resolve it this way.
First, enable debugger mode in your android device.
Go to Device Manager from Start Menu and try to find ADB Interface with an error symbol on it. This generally happens because windows sometimes fail to load all the mobile device drives.
Next, Go to http://adbdriver.com/downloads/ and download the driver installer, unzip and run it.
Now go to Android Studio and you should find that everything is working fine.
Chill....
same here... but I hope you can avoid this problem the same way I Did.
There is an "universal ADB Driver for all Android Devices".
Yep... sounds like magic.
Just follow this link.
https://devs-lab.com/usb-adb-drivers-for-all-android-devices.html
Fun fact there is no "Step 5" in that article so I'll give you.
you have to enable "USB Depuration" from "Developer Options" connect your cellphone to computer as a "MTP storage" , after windows detected your cellphone as a "Portable Device" Execute ADBDriverInstaller.exe (that downloaded from devs-lab)
check the device list and your cellphone will say "Driver incorrectly", select your cellphone and press install.
Step 6: Once the process is completed, you’ll see something like the image that appears there (in the link).
I hope that somebody else work this
Go to Run > Edit Configurations...
Under Deployment Target Options select Show Device Chooser
Dialog from the drop-down-list
See picture for reference
After struggling with this problem for a while, I found that there are certain cables that can only charge your phone, and even though they seem to be working, they do not allow your phone to be used as a "Media Device" and therefore Android Studio does not detect it.
Go to
Tools | Android | Enable ADB Integration
Make sure it's enabled. When I upgraded to 2.X it was for some reason disabled for me and it took me hours to find it.
I just cannot beleive why it is so difficult! let me try again and please check my steps again:
I installed Android Studio 2.0, then run Computer/OS(C:)/....../Android Studio/bin/studio.exe.
The Android Studio window appeared in my working area Computer/OS2(J:)/Users/MyAccount/Desktop/.
I connected my mobile with my computer, Cpmputer/A0001/ appeared, from it, I can see the files in my mobile.
I clicked the run icon in the Android Studio window, a "Select Deployment Target" window apeared with message "No USB devices or running emulators detected".
(I got two USB ports and tried both but got the same result.)
Finally found the solution : )
1. Install device’s required driver. (for me it was motorola device
manager)
2. Download Google Usb Driver from SDK Manager
3. Open your phone's setting->developer options and turn on USB debugging.
4. connect your device to computer
5. Go to Device Manager from Start Menu and try to find if there is ADB Interface with an error symbol on it.
5.1. If yes, then right click on the ADB interface->Update driver
software->Browse my computer for driver software-> Let me pick from
a list of device drivers on my computer->Select Motorola ADB interface
5.2. Now one confirmation will pop up in your mobile, accept it
5.3. Now you should see no error mark beside the ADB interface in your
device manager
There are 3 steps to set up your phone for debugging:
1) Change your phone to developer's mode by going to Settings, About Phone, Software Info, Android Version - tap at least 7 times on the Build Number text. You will get a message saying you are now a Developer.
2) Enable USB Debugging in Settings - Developer Options. Make sure you are not connected to your USB port to see the USB Debugging option enabled, otherwise it will be disabled.
After you plug in your USB, swipe at the top of your screen, you will see USB Debugging on.
3) Make sure USB connection is set to Photo Transfer (or MTP - Transfer photos and videos). After you plug in your USB, swipe at the top of your screen, and you will see Tap to change USB options on the menu. Tap it, and select Photo Transfer option.
Perhaps your mobile manufacturer does not provide the proper driver.
Go to Device MAnager and look for: Android Composite ADB Interface. If it's there, the driver is properly installed. If not... You and I are on the same "wagon"...
I tell you: Acer? Never again.
USB debugging somehow got turned off under developer options on my Samsung. Turned it back on and it worked, but only by clicking on "debug app" instead of on "run app".
With me, when connecting the mobile to the pc, three options appeared on my mobile.
Charge this phone
Transfer Files
Transfer Images
I thought I should select "Transfer Files", but it dd not work
But it only when works I choose "Charge this phone"
Few ways to resolve this problem.
Case 1: Install PdaNet+ in your system. (worked for me).
Case 2: Enable the USB debugging option in your mobile. Setting > developer > Check "USB Debugging".
Case 3: Change from MTP to PTP.(sometimes vise versa works).
Question is Your development sdk no mobile version android sdk Platform.
For example, my android phone system is 6.0, i need download sdk Platform 6.0.
First, try to revoke the usb sessions in the developer options, then try downloading an oem usb driver
If then doesn’t help you can try opening the device manager on windows, right click on your phone, select uninstall. This worked for me if I had the same issue.
I couldn't find my android phone or any USB device I connect to my windows laptop on the hidden icons. Well, my mouse and phone could charge but I can't seem to see my phone in the File Explorer option.
I prefer running Apps using my phone rather than emulator in Android Studio and yet I couldn't see my phone when I connect using the USB.
This helped me solve all my problems after several hours of searching for solution.
Download Universal ADB Drivers - One size fits all Windows Drivers for Android Debug Bridge
Please use this link: https://adb.clockworkmod.com/
I hope this works for you like magic!
I can see all the devices I connect using the USB cable and my mouse receiver.
I am trying to connect my android device on mac to test application I developed.
First I installed USB driver, then I activated in my phone the developer option by tapping on Build Number and then tick USB debugging option.
Once I did all those steps when I connect my android mobile, my Mac still not recognize my device.
Any idea to solve it?
Maybe it's your USB cable, try another one.
There are two types of USB cables:
for supplying power only
for supplying power and data
I after few research and testing of existing solutions, I found mine, my issue was released while I have installed Android file Transfer for Mac
I experienced the same problem with a Moto X and my Macbook Pro. I tried many of the suggestions (installed Android File Transfer, tried different usb ports on my computer, Settings => Storage => USB computer connection => toggled between MTP and PTP, etc.). None of these other recommendations helped.
It finally worked when I tried a different micro-usb cable.
Bizarre. You definitely want to first enable Developer Options first by going to Settings => About Phone => tapping Build number 7 times to display Developer Options. From there, you want to enable USB debugging.
I found this solution to be helpful to resolve this problem
Connect your Android to your Mac via USB.
Unlock your Android's screen. ...
Swipe down to open the Android Notification Panel.
Tap the USB option in the Notification Panel.
Tap "File transfer" or "MTP."
Click the Go menu and select "Applications."
Double-click "Android File Transfer."

I had this problem. The only solution was to reboot my computer. Then it started working again.
Just to add my experience here. I had a similar problem with my mac book pro and my Google Pixel 1 device. For me when running adb devices locally, I was no longer showing my device on the list. I would see any emulators I had running, but not my physical device.
My solution and steps:
Go to the "Settings App"
Go to "Developer Options"
Revoke USB debugging Authorizations
Toggle Developer Options off / on
My device then prompted me to allow debugging from my computer and everything continued to work as expected. adb devices resulted in showing my connected device.
Hopefully, this will help someone else if the above does not.
Make sure to have debugging by usb enable on your device.
It is an option inside "Developer options"
I've recently (2018) started to have this issue, and have found the only way to get my device connected is to use a USB hub. I have not been able to track down a root cause but will edit this answer if I can find a solution rather than a workaround.
I connected my Android deceive with my mac:
1) If you use Android studio, you may update to latest version of 1.0.2 or 1.1 preview, because lower version have some problem with ADB connection.
2) You may restart your IDE once again.
3) You may go to settings -- storage -- three docs on the right up corner -- USB computer connection -- enable MTP
I have an HTC U11 and a MacBook Pro (2017). It used to work most of the time, but I experienced issues with it once or twice. Then a restart of the Mac solved the problem.
Recently I was not able to USB debug. adb devices gave nothing, even though my phone said I'm USB debugging (even asked if I wanted to).
After trying many things the solution was to connect my phone and run HTC Sync Manager (I also had to update it). Then it magically started to woek.
I hope it helps somebody.
check your android sdk tools, install your sdk-plateform-tools package.then it is ok
For me what fixed the problem is
i clicked on the notification "USB for file transfer" in the
notification panel on the phone
Clicked on "Transferring images"
Than I clicked on "Transferring files / Android Auto" and it was fixed.
I've connected my Samsung Galaxy Tab device to my Mac. Yes, I've turned on debugging. When I go to run my application to test on the device the device is not listed on the Android Device Chooser menu. Running the ./adb devices shows no results.
NOTE: Posting this question for others to find. When looking for the solution earlier all I was able to locate were answers to broken links to device driver downloads for Windows.
Make sure you uncheck
Settings > Applications > Unknown Sources (Allow installation of non-Market applications)
Turn on USB Debugging inside Settings > Applications > Developers Settings
If you're trying to connect to a Mac, I had this issue with a Samsung Galaxy Tab 10.1 running Android 4.3. To enable developer options, open the Settings app, tap on "About device" under the "General" tab and then tap on the "Build number" repeatedly (it's grayed out but you can tap on it anyway). A small pop-up will appear showing the amount of additional taps you need to do to turn on these options.
Once enabled, just turn on USB Debugging and it'll show up in Eclipse just fine.
I had this problem on my Mac and after 30 minutes tried switching USB ports and it finally started working on the second port.
I fixed it by reboot the device (Samsung Galaxy Tab2 7.0)
Update your driver for samsung. It can be found here: http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
Connecting your phone after development mode is on, and USB debugging is on.
At connecting to the PC the phone asks to trust this location. Finally.
This fixed my problem while all other tips were incomplete.
It does not answer your question of how to get ADB to see the device - I could not get that working. But what I did to install an APK I needed to test was to put it in Dropbox on my computer, then install it from there on the device.
Connect your device via USB hub instead of directly connecting to one of the usb ports on MAC. It worked that way for me. Please give a try.
There's also a pop-up that comes up at times requesting the currently connected computer to have access to your device(not to be confused with the Linux not supported pop-up; it lies ; ] ). I continued to receive Target:Unknown in Eclipse until I managed to catch it and accept. This is on a Samsung Note 8", which I believe is registered as a Tab 10.1 in my Arch Linux udev rules.
It may also happen that USB debugging is not checked on your device. Please go to developper options in your device and check it is enabled.
By the way, for devices with android Jelly Beam (4.2) and later versions, you will find out that this option is hidden. To activate it, click 7 times on the compilation number, and the option will be activated.
Tried everything, nothing helped. Including
USB debugging enabled
MTP/PTP
ADB restarted
Device/PC restarted
Tried Samsung's USB driver
By tricking/modifying driver installer, installed Google OEM Usb drivers for Galaxy Tab.
All software up-to-date
The only thing that helped is installing Kies3 + setting PTP on device, instantly authorization pops out in device. Everything OK now.
Kies3 download here: http://www.samsung.com/uk/support/usefulsoftware/KIES/
Enable USB Debugging mode solve the problem!
For those who don't know how to enable it (it's very hidden on Android 4.3 onward), see this.
In my case, this solved the problem:
unchecked the Settings->Security->Unknown Sources,
clicked on the upper left corner and changed USB mode from MTP to PTP,
unplugged/plugged the device, and
clicked OK on the USB debugging prompt.
Had this problem last year, never solved it. Again, after googling high and low, I could not find a cure for the USB debugging flakiness. Now for the good news:
1) Root your device. 2) Install adbWireless widget from Play (I am in no way associated with the author).
You are now good to go. After starting adbWireless and following its directions, you can now debug through adb wirelessly to your device, in my case, the original 7" Galaxy Tab.
