Eclipse is not detecting my phone. It's a Samsung Galaxy S2 HD LTE, Android version 4.0.4. Working in Windows 7. I have enabled USB debugging and updated the driver for it, but when I go into Eclipse Run --> Run Configurations --> Target it is not listed.
Not sure if this is relevant but I heard in another thread that the build target for your project has to be <= to the version of your device. If this is the case, all the options here are higher and there doesn't seem to be a way to add another so I'm not sure what to do. Also checked the manifest file to see what the min SDK is. It's 8 (which corresponds to android version 2.2) so that is fine.
I'm wondering if it has to do with "Android" being listed under Other Devices in the Device Manager (as per image below). I'm not even sure what this is. The phone itself says it's already updated, but when I try to update Android it can't find the driver software.
Another issue could be that when I connect the phone to my PC, it lists it as a camera instead of a mobile device, and displays the message "Connected as a camera" on the phone itself. The first time I connected, it also showed some error message about how device was not installed properly, but I haven't seen this message again and so not sure what to do about that, or that stupid Autoplay window that pops up every time I connect.
If you have any ideas please let me know!
Check if your Android Composite ADB Interface is correctly installed.
You can refer OEM USB Drivers and Debugging on real device for more details.

I am working at an android studio project and I always work with my own physical device SAMSUNG S7. It always worked (for a few weeks now) but today suddenly from one moment to the other my device cant be recognized by android studio anymore. I didnt change any settings! I just changed a line in the code (like a hundred times before) and after it my device is not shown in the list of devices. There is only the virtual device which is useless for me because it never displays the app correctly. Just my physical device shows the app correctly so now I need help. Otherwise I cannot continue programming.
I tried to reopen android studio and restart my phone but it didnt help.
Changing the cable plug mode (credits to Hack06)
Just swipe down the OS status bar, and tap on the device, then choose another connection mode.
Installing Samsung's development drivers
When this doesn't work, try installing the drivers provided by Samsung to improve developments. These can be found here.
USB Debugging
USB debugging may have failed. Or all of the developer settings have been reset. Try that
Reboot your phone into ODIN mode
Caution:
ODIN mode is in charge for flashing your Android phone, and if you’re not careful, you can cause permanent damage to your phone.
This solution applies only to Samsung’s devices, since they are the only devices with access to ODIN mode.
A guide how to access ODIN mode for your phone can be found here.
Install KIES software
If nothing worked till here you might want to download KIES software.
KIES software only works for Samsung’s devices.
Samsung KIES is part of Samsung Smart Switch.
Download here.
Google - Android USB Driver
My last suggestion would be to install Google's Android USB drivers. An official guide can be found here.
This may sound obvious..
but sometimes it could be a cable issue
even if it's charging it could not transfer data
try a new cable
I've been working on the HelloWorld app for a few weeks now, overcoming many little hurdles, and I think I've reached the last one. I'm working out of 'Learn Android Studio' by Adam Gerber (not an endorsement, just happens to be the book I'm using). I have an HTC One.
When I open the device manager, there is no device listed. In the terminal, I issue the command adb devices and I get the heading "List of attached devices" with nothing listed. If I click the green run arrow, I'm asked to choose my device, but my device isn't shown.
I used to get the error "Unable to obtain result of 'adb version'" when I opened the device manager, but I don't get that anymore, for some reason. But now, when I open Android Studio, I get a Windows Firewall window telling me that some aspects of Android Studio are blocked, including public networks. I don't know if this is the reason for my difficulty or not (I don't think connecting my phone to my laptop is like a public network, is it?).
I went to the developer.android site and followed the directions for connecting a device:
How to connect an Android device to Android Studio.
Step 1 is: "Verify that your application is "debuggable" in your manifest or build.gradle file." The details on how to do it are provided, and I made the appropriate addition to my build.gradle file.
Step 2 is: "Enable USB debugging on your device." This is the thing where you tap your phone at a certain place in the settings to enable development capabilities. I did that.
Step 3 is: "When plugged in over USB, you can verify that your device is connected by executing adb devices from your SDK platform-tools/ directory. If connected, you'll see the device name listed as a 'device.'" As I mentioned above, I get a heading for a list, and no items listed. My book says on page 23: "If your computer does not recognize your Android device when you connect to your computer via a USB cable, you probably require a USB driver. If your computer initially recognizes your Android device, you should probably forgo installing a different or newer version of the USB driver, as this could cause the USB connection to fail." Since I've transferred image and music files to and from my HTC One dozens of times, I followed this advice and did not install a driver (Actually, before I read this book, I had started looking for a driver, following the links on the developer.android site, but I wasn't able to locate one).
On another site where programmers congregate, someone gave me this list of 4 items to check:
- Have you reinstalled adb? (I'm not sure what this means.)
- Do you have the DeveloperOptions SubMenu enabled on your phone? (yes)
- Do you have USB debugging enabled on your phone? (yes)
- Do you have AllowMock Locations enabled on your phone? (I did not, and I enabled it.)
Regarding the first item, my adb is an exe. How do I 'reinstall' that? I responded to his message, and he has not responded to clarify what he means.
Regarding mock locations, that was not enabled, and I enabled it and tried again to connect my phone to Android Studio. That's when the Windows Firewall window showed up for the first time. I don't know if it's because I enabled mock locations or not.
I also tried rebooting after starting the adb, as suggested by my book, on page 25, but that didn't do anything. "If after restarting the ADB server you still don't see the device, it's possible, though unlikely, that the USB driver requires a system reboot to take effect." I've noticed that adb starts up when I boot up (I tend to keep the task manager open), so I know my problem is not that the adb is not running.
I looked at many similar questions on this forum, and the most common advice seems to be to install a driver. Since my book says a driver might not be necessary and could ruin my USB connecting ability, and also since some programmers stated that their Android Studio connection to their phone was failing in spite of installing drivers, I'm not rushing to install a driver, especially since I need USB connectivity on my phone for my job.
So this is where I am. So, what about this statement in my book that if my laptop can see my phone, I don't need a driver. Would that be true? What else could be the problem?
Any help/suggestions/comments gratefully appreciated.
The fact that your computer can see your phone does not mean that you don't need a driver.
What that means is that your computer has the appropriate drivers installed for recognizing your phone as a media device.
What you need is for your phone to be recognized as an ADB device. These are often different drivers from the phone drivers that are installed by default, as the vast majority of users do not need to use developer tools with their phone.
If you can find these drivers from HTC, then they are very safe to install and the risk to your computer is negligible. Google's USB drivers installed via the SDK manager work for many devices and are also safe, though I cannot speak as to whether they will work with the HTC One or not.
I'm trying to use my HTC Desire as a test phone for my Android application, but Eclipse just can't see it, now If i go to device manager there is a yellow !, i click uninstall, re-connect my HTC phone to the computer and it can not install the drivers, can anyone help me fix this problem? I really need to be able to use my HTC phone as a test device.

I always had the same trouble with HTC phones and some Samsung phones as well even when using the official driver.
I found if you install PDANet http://pdanet.co/ this installs the driver for you and it always seems to work. You don't actually need the software afterwards and can be uninstalled, but it successfully installs the driver and device is detected.
Installing HTC Sync Manager on Windows 8.1 resolved my problems with HTC Desire 600.You can download it from here:
http://www.htc.com/www/support/software/htc-sync-manager.aspx
Details brought from here:
http://grindheadgames.com/htc-desire-showing-adb-devices-fix/
Important Note: I also noticed there is a checkbox in USB Settings called 'HTC Sync Manager'. You should check it to enable 'USB Debugging'. Otherwise although you have enabled usb debugging in 'application development' section, USB Debugging will not work.
I just upgraded my phone to 4.2.2, but now i cannot use it in eclipse anymore.
I tried rebooting the device, reset my debug-settings but I cannot get it to work anymore.
I saw it is already a registered issue. There are some new security enhancements, so there should be a dialog (see here at bottom) but this dialog doesn't appear. I don't have several accounts on the phone, which is pointed out in the issue..
Anyone any suggestions?
EDIT: Look at accepted answer below, this should cover all cases. In my case, there were some packages missing, which weren't shown in the Android SDK Manager. I just found the Packages -> Reload in the Android SDK Manager... And I thought this happens automatically
You need three things in order to make sure this update goes smoothly:
Make sure your device is actually running 4.2.2 and the problem is not something else
Your SDK is updated to the latest tools. The adb binary in all but the latest version does not support the 4.2.2 security enhancements.
You are on the main account of your device in case of multiple user accounts.
Connect your Device to your computer and execute adb devices (make sure USB debugging is enabled). You should see something like this:

Right about now, there should be a dialog on your device that looks something like:
Check the Always allow from this computer box if you want and click OK.
That's about it.
Some other things to check:
Make sure your USB cable isn't broken. Sometimes, the smaller cables break inside the main one, and your device may charge but have no data connection. Try with a different cable, or try accessing files on the device over USB (this will go fine if your cable is fine)
Make sure you're using the newest version of adb. Even after I updated my SDK tools, I couldn't get my device authorized when using adb. I eventually figured out that the Nvidia install of the NDK and SDK tools had updated my PATH variable to use the adb from that install, which wasn't the latest update. By using the adb in my newly updated install, I was able to get it all working.
For me it was solved by changing Nexus 7 tablet to "Camera(PTP)" mode.
Check out this blog post on how to do it.
After USB connection of Nexus 7 and confirming digest on Nexus 7, also connecting through TCP/IP with ADB worked.
Wierdly, unchecking and rechecking the "Allow USB Debugging" option popped me the window and selecting "ok" solved my problem.
If none of the solutions worked for you then Reset ADB.
Go to Devices ---Click the right most down arrow----Select Reset ADB from the list.
I had tried everything suggested here and suggested in every log/blog that I could find in google, but still no go. The USB cable is known to be good. ADB is version 1.0.31 (as shown with , USB Debugging is enabled in the Nexus 7 tablet, the SDK was updated to the very latest tools as available on 1-mar-2013 for 4.2.2/API 17. I had tried both Media and Camera modes for USB, rebooted windows, rebooted device over and over again, re-installed latest google USB driver, etc. etc. but ADB Devices still showed nothing.
I hard reset the Nexus 7 tablet thinking that maybe the screen to allow usb debugging had appeared but got hit with cancel. But that didn't work either.
What finally worked was:
going into windows control panel | Device Manager,
selecting NEXUS under Portable devices,
then in the Driver tab clicking on update and manually selecting the Google USB driver (the check feature said it was up to date). Previously, the date shown was in 2006, afterwards a date in 2012 (but more on this in a moment).
That didn't fix anything though.
So then I switched USB from MEDIA device to Camera device - THEN it wanted to install driver software, so I let it do that. Afterwards, I noticed that the driver for the Nexus was back with the 2006 version, BUT then ADB DEVICES FINALLY SHOWED OFFLINE!!!! HALLELUJAH AND the Nexus was displaying the Dialog to allow USB debugging, and it now all works.
What I am not sure of is what step actually solved the problem. I don't think it was necessary to hard reset the Tablet, but the fiddling with the device driver wasn't a very convincing solution either - I don't think the driver was corrupt - but maybe it had to be changed to get the right driver associated with the tablet when connected as a Camera Device. In any event, it is necessary to connect the tablet as a Camera device for ADB to work...
Restarting device or enabling USB debugging did not solve my problem.
However I changed USB PC Connection to "Camera(PTP)" mode and adb devices showed the device id of the phone.
After reading a lot post talking about this particular problem, I actually solved it by resetting user permissions on files (that were owned by root): ${HOME}/.android/adbkey and ${HOME}/.android/adbkey.pub
Go to Device Manager and uninstall your device and remove from USB
HAve you CMD opend and make sure you are at least in ADB Help.
Connect device to USB and continue with steps provided by Raghav Sood - few answers ahead of me.
Worked for me just fine
I tried with this custom build and it works for me. Now I can see my logcat in Eclipse again.
https://github.com/khaledev/ADT/releases
Download the zip file then in Eclipse menu Help > Install New Software... > Add > Archive... Just pick the downloaded zip and do the rest of the install process.
ive got a slight problem with Eclipse. For some reason i cant find my device in the run configurations. USB Debugging is enabled on the phone and even the logcat output when the phone is attached in eclipse works, however i cant find the phone. If i select manual in the run configurations everything gets disabled in the menu like this:
Any ideas why? Phone is a HTC Desire HD running android 2.2.1 and i have the Froyo sdk installed.
Thanks in advance
That window allows you to choose your preferred Android Virtual Device.
If you chose "Manual", when launching the application from Eclipse, Eclipse should display a dialog, asking you on which device the application should run -- your real phone should be present, in that dialog.
As an example, here's how this dialog looks like for me, after I've choosen Manual in the one your posted :

The 192.168.0.10:5555 phone is my HTC Desire, connected over wifi (I would get the same result with USB -- except I would have the model's name of my phone, and not it's IP address)
Maybe your platform target is sdk version 10. Your Desire only has 8. Does your manifest maybe include the line:
<uses-sdk android:minSdkVersion="10" />
