Why doesn't Android Studio detect my device?
What I tried:
-I enabled developer options & USB Debugging on my Android phone
-I checked that the USB driver for my phone is installed & updated
-I checked that the USB option is set to "File transfer / Android Auto"
-I uninstalled Android Studio & reinstalled it.
-My phone can be found when running "Troubleshoot Device Connecions", but it says "Unable to locate ADB"
-I have checked that I have a SDK selected
What can I do?
Android Studio doesn't recognize my phone... It worked in the past with the same computer & the same phone.
I had this problem before
In my case, there were two different versions of ADB on my computer.
(which I had installed manually not from android SDK)
after uninstalling the old version and replacing android studio's own adb the problem resolved

I have been using android studio for the past 5 months and everything was fine. Suddenly, yesterday when i tried to debug my app android studio gave me the error of 'adb.exe start-server' failed -- run manually if necessary.
In an attempt to solve this, I
Killed adb.exe via task manager, restarted android studio and got the error
Opened command window,navigated to platform tools, adb kill-server and adb start-server, restarted android studio and still got error
Then,
I downloaded the latest platform-tools of version 28 something from the documentation.
Updated SDK tools from SDK managet to version 28.0.3
Updated Android emulator to a version of 28
Tried to debug my app, got no 'adb.exe start-server failed' error but my device is not being detected by the android adb despite it is detected by my laptop
Then i started again the command window, restarted the adb server, then i checked the connected devices on the adb by typing 'adb devices' but no devices was shown in the list.( maybe the problem is something here)
I toggled among the usb options on my phone, still my device is not detected on android.
Can somebody help me on this please?
Note: My android device is on debugging mode and this is the same device i have been using since 5 months on android studio.
Install and configure your Android device:
Install the USB driver for your Android device.
Enable USB debugging on your Android device.
If necessary, install the Android development tools (JDK/SDK/NDK).
These libraries are installed by default by the RAD Studio installer.
Add your Android SDK to the RAD Studio SDK Manager.
Connect your Android device to your development system using the USB
cable provided with your device.
At the AutoPlay prompt, select Open device to view files.
In the Control Panel, search for and select "update device drivers".
In the system Device Manager:
Your Android device should be listed under Portable Devices. Locate
and right-click your Android device, and select Update Software
Driver.
Browse to the \extras folder in your installed directory, and
select the folder that matches your Android device. Then click OK.
For example, select google for the Nexus 7 or Nexus 10 tablet.
If you do not find a folder for your Android device, see Installing the USB Driver for Your Android Device.
Verify that your Android device is now:
Listed in Windows Explorer, below the system disk drives, along with your mapped network drives.
Displayed in the Target node in the Project Manager.
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
I searched trough many questions and couldn't find an answer that fix my problem.
I'm new on creating Android projects and I'm still getting familiarized with the eclipse platform.
To the point, when I run my project I get this error
No compatible targets were found. Do you wish to add new Android Virtual Device?
I changed the AndroidManifest.xml from targetSdkVersion="18" to "15" (Which is my device level, Android version 4.0.4, correct me if I'm wrong)
Then I clicked on Run Configuration and switched from "Launch on all compatible devices/AVD's" to "Always prompt to pick device", and still couldn't get the project to work.
When I reverted the Run Configuration I get this output everytime I try to run the project
[2013-12-15 21:27:28 - MyFirstApp] No active compatible AVD's or devices found. Relaunch this configuration after connecting a device or starting an AVD.
What's the meaning of both messages? How can I make it work?
Some details:
Android Version: 4.0.4
OS: Windows XP
Samsung Galaxy S DUOS
Please follow the steps
Step 1
Check if the device driver is installed successfully. If not, download the drivers and plug the device again.
Try this link to download the driver software - http://samsung-kies.en.softonic.com/
Step 2
Click Start-> Run-> CMD. (Go to command prompt)
Navigate to the android SDK platform tools path.
Type adb devices
Now you should get the device listed and a tag "device" next to the device ID
Step 3
If you get "no devices found", type adb kill-server
Type adb start-server
Now type adb devices.
Now you are good to start testing your applications on device.
You have to have Samsung Kies installed on your computer so you can have drivers for your device, also, from eclipse:
window -> show view -> devices
if you don't see your device here, this means either your ADB is not running, or your device is not recognized by your computer
also verify you have debug mode enabled in your device
Do you have the usb debug driver for you device installed? This is the driver that allows your device to "comunicate"with eclipse in order to debug
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.
I downloaded the emulator and followed the steps on the android website on how to install the SDK. i made an AVD and everything showed up on my computer screen perfectly, but now the problem was installing it to my phone. i can't find the instructions the android website on how to install it on my device.
If you're using the ADT Plugin for Eclipse, it's totally seamless. Just connect your Android device to your computer like normal and mount it. Then in Eclipse, right click your Android project, and say Run As -> Android Application. It will actually run the app on your device.
And if you unplug the phone and run the project again through Eclipse, then it runs inside the emulator. It just works. =)
run this console command:
adb -d install -r /path/to/your.apk
or windows version:
adb -d install -r c:\path\to\your.apk
As Drew said - if you're using Eclipse on the PC, then it's just a case of plugging in your phone and running the app from within Eclipse. There are just two things you might need to do:
On your phone, go to settings -> applications -> development -> "enable USB debugging" and also "allow unknown sources"
If you've got both the emulator running and the phone plugged in at the same time, you will have to change the project run properties to "manually select the target device". Otherwise it might try to install the app on the wrong one.
You don't need to install the SDK or anything like that on your phone. From your phone's point of view, it's just running an application like any other, since Eclipse (well ADB really) fully installs the app onto your phone when you test it.
