Can't Get Debugging To Work On Nexus 7

I'm trying to run my app while debugging on my Nexus 7, but it always loads in the AVDs instead of on the tablet.
Here's my checklist of things I've done:
Went into the settings on the Nexus 7 and enabled USB Debugging.
Installed the official ASUS Nexus 7 drivers. When I connect it to my PC, Windows 7 64 bit pops up and says the Nexus 7 is connected and the drivers loaded successfully.
Connected it to my PC (Windows 7 64 bit) and it pops up and saying the Nexus 7 is connected and the drivers loaded successfully.
However Eclipse doesn't detect it at all. The app loads the AVD instead of it. And if I go to Run As->Run Configurations->Target, it's not listed. If I select Launch on all Compatible Devices/AVDs and choose Active Devices and then try to run, I get the error "No active compatible AVD's or devices found. Relaunch this configuration after connecting a device or starting an AVD".
The app is set to be compatible with Android 4.1.
Suggestions?

The only way I've ever gotten it to work is switching the 7 from a media device to a camera.

Strange. Unfortunately it still doesn't work for me. Same symptoms. Thanks though! Any other ideas?

I found I had to fiddle with the drivers a bit to get the proper adb connection. Check Device Manager and make sure it shows up under Android Phone->Android ADB Interface. If you see anything else you'll need to uninstall the offending driver and reinstall.

Ehhh...Crap. You're right. Device Manager shows Other Devices -> Nexus with a caution sign on it. Weird cause when I plug it in it'll ask me if I want to transfer photos and it'll mount it as a drive and everything....grrrrrr. This might be annoying.

I'm trying to remember exactly what I did to get the right driver to install. I think you need to uninstall the all drivers being used and then make sure that USB debugging is turned on in the Nexus before plugging it back in. I used the Wugfresh toolkit which includes tools to check what drivers are lurking around in your system.

Finally got it. Turned out, the driver files were no good. I got them from a link to Asus's site from another thread. I googled their site for different driver files and found the correct ones:
http://www.asus.com/Tablet/Nexus/Nexus_7/#download
It should be a zip file with USB in the title.
Thanks for the help!

I can confirm this, I switched it from MTP to PTP and installed the driver, and everything is working now. It's showing up in the ADB list.

Download the asus drivers and extract the zip file. Plug in your Nexus 7. Go to Device Manager -> the device (might be listed as an android device) -> Update driver. Browse to the extracted folder.
On the Nexus 7, make sure USB debugging is enabled. And, when it connects, change it from being connected as a media device to instead being a camera device.

Thanks. I ended up being able to do it with the one click root program it helped me get the drivers super happy. Now my galaxy nexus and nexus 7 are rooted. Haven't had something rooted since my Samsung galaxy s fascinate

Been at this fir 3 days. Installed, uninstalled drivers. Got ASUS drivers. Switched from Debugging on to off, then off to on. used Camera, used Media....The closest I come to seeing Nexus7 in Explorer or Computer is INTERNAL STORAGE/DCIM OR CAMERA.
I am unable to see any files, no matter what I do. So, now I must ask this: Must I be rooted to see android files? I doubt it, but I never used a Nexus before. Quite frankly, this tablet is awful for use with a PC. I need help-can u help me, pls.

Can I ask for your help guys? My Nexus 7 v1 is stuck on boot loop (either stuck on google screen or sometimes would proceed up to the nexus animation screen) and I've been trying to fix it with the Nexus Root Toolkit (NRT). I just have problem proceeding with the steps since the toolkit advices me to enable my device's USB DEBUGGING (open device , go to settings, then developer options etc) which I CANNOT POSSIBLY DO COS AGAIN, NEXUS IS JUST STUCKED ON BOOT LOOP.
Can you suggest OTHER ways I can enable USB Debugging in Nexus 7? I would greatly appreciate your help.

Nexus 4 usb storage doesn't show up in windows after Root

For some reason when i connect the phone the the computer, it wont show up MTP.. but for PTP it works.. When its connected the small window pops up alerting me the "nexus 4" was connected but thats it, the drive wont show up.
I think getting rid of the adb drivers I used so it doesnt show up as "android adb inferface" will solve the issue... but whenever I uninstall the drivers from device manager and delete
the usb drivers folder.. it still installs them right back when I connect the usb!
*edit* it detects on my dads computer just fine and MTP works.. i think it has to do with the adb drivers i installed.. wish i knew how to uninstall them for good so windows wouldnt automatically install them again even with deleting the drivers folder off my harddisk

Bump. Tried everything to no luck

Did you find a solution to this? I am having the same problem. The original drivers that installed worked just fine over MTP but not adb. Now, abd works but my Nexus wont show up as an MTP device.

[Q] Nexus 7 MTP

Weird problem I'm having with Nexus 7 and MTP. So my girlfriend and I both have nexus 7. I recently Flashed my Nexus with AOKP and everything went smooth. Can connect my nexus 7 to my windows 7 ultimate 32 bit OS and it gets picked up and I can easily transfer files to and from. Last night I went to connect my girlfriends nexus 7 to same PC to transfer some movies for her and it would not pickup as MTP device. I switched from MTP to PTP. It gets picked up as PTP but I can't transfer movies to it, just pictures. So i changed it back to MTP and nada. In MTP mode the nexus gets picked up i see it in device manager as ADB device, nexus is charging while plugged in but does not show up in windows explorer. So i disconnected plugged in my nexus 7 and comes up just fine as MTP device. Switched back to hers and still nothing. So i thought it was her nexus. I decided to connect it to my mac and download the android file transfer app. That worked fine and I was able to transfer movies to it. connected it back to the windows machine and still nothing. I want to do a factory wipe on it and flash it but i really want to resolve this problem. I thought about just doing a factory reset to see if that fixes it but there has to be something else i can do. Also the only was I can get nexus root tool kit to pick it up to root and flash is to have it in PTP mode. any ideas? any help is greatly appreciated, thanks for listening!

Having a hard time thinking its a driver issue since my nexus gets picked up fine. wanted to add that I rebooted the pc and nexus with same result.

Try going to device manager and uninstall the drivers from your Nexus. Then unplug and replug it again and let it install its drivers again.

Try using USB Deview and delete all drivers pertaining to android. Then download the google usb drivers for Nexus 7 and see if it fixes the problem.

Try an app on the market called "stickmount" it should do the trick.

Another thing i just remembered it could be the cable your using. Speacialy if your nexus 7 are different i mean like one is 3g the other is wifi or one is 16 gb the other is 32 gb' so i would suggest using her original cable on her nexus 7 and same thing to you. About stickymount i dont think thats gonna work, kinda was thinking something else.

think i just made it worse used usb deview and now I can't get my nexus to show up as MTP device. Both nexus are 32gb wifi only. I used usb deview to uninstall all android and nexus 7 drivers...there were quite a few...downloaded nexus 7 drivers from asus site...when i plugged the nexus in windows installed its own driver, i tried to update the driver with driver from asus but windows indicated that the latest driver was already installed...I think i'll try installing the drivers from the root tool kit and see what happens ...ugh

something is different between the 2 nexus, which doesn't make sense. They're both 32gb/wifi. So I used usb deview to uninstall all drivers. Then useed Nexus root tool kit to install drivers (somewhat) only went through frist 3 steps or so and windows installed ADB and Nexus 7 MTP driver and I was able to see my girl friends Nexus now as MTP device and transfer files to and from...just to play safe i used the USB cable that came with hers. I then connected my nexus which originally worked fine (but then i jacked up the drivers and they both wouldn't connect) and now does not get picked up as Nexus MTP, rather only ADB device shows up for it. So it looks like windows only likes one of them? Very strange, I'll keep playing with it but doubt I will be able to get them both to be picked up by windows as MTP....gotta love windows

so the only thing i notcied is when her nexus is connected if you go to control panel then devices and printers hers is now seen as Nexus Portabl Media player (MTP) and when mine is connected it comes up as Nexus 7 Unspecified and only driver i can install or updated is ADB..where with her device it is seen as ADB in device manager and also comes up as portable device nexus 7. Now i know if i use usb deview and uninstall all drivers then install mine first mine would probably be fine and then hers would prob not work

I have the exact problem ... but under win8. I have two Nexus 7s which I didnot have any (connecting issue) on my previous win7/64.
After upgraded to win8, windows only mounst one and refuses to mount the other. I can remove all devices relating to the Nexus7 then win8 will
mount the next N7 then refuses the other (the nexus7 is recorgnized but not mounted). Seems like it indexes the first Nexus then afraid to mount
the other as it sees a difference.
No solution so far, except everytime I want to work with the other Nexus, I have to remove&re-install the driver.
It has no issue when I connect other Android devices (AsusTF101, Nook Color, Samsung 4 Player).. Just refusing the identical twin.

Yup, it appears that USB Debugging suffers some sort of identity crisis after a root or OTA to 4.3 - toggled debugging off & the MTP mount worked as advertised.
Had to revoke all debug authorizations and re-init for USB debugging and MTP to function together.
SIGH!
Cheers

I started experiencing this issue right after the OTA to 4.3 update on both my wife and I's rooted Nexus 7 Tablets, both first gen and current. The issue was resolved by removing the drivers from my computer and before reinstalling them revoking all ADB/USB debugging authorizations. I'll post the the steps I took.
1. Followed the Wug Fresh steps for removing Android related drivers (I have owned a lot of Android devices so I cleared the slate of everything)
2. Turned off debugging on both tablets with MTP on
3. Revoked USB debug authorizations on both devices
4. Connected the first gen N7, let drivers install
5. Turned on USB debugging while still connected
6. Repeat 4 & 5 for second gen
7. Both tablets connect with no issues and I have adb access to them

I suggest you have a look here.
this worked perfectly for me.

[Q] No MTP connection

When I connect my Nexus 10 to my Windows 7 computer, the only driver installed is the Android ADB Interface.
I don't get the MTP connection, and my tablet does not show under "My Computer".
On the Nexus 10, I have tried turning debugging on and off, and I tried deleting the driver from the device manager in Windows and reconnecting it and hoping it would re-detect and re-install, but still no go.
Can anyone help me to get the MTP connection working? I think it worked on the initial Android version 4.2, but after the Nexus 10 system updates, it stopped working.
Thank you

You shouldn't have problems if you are on 4.2.2 (as I see on your sign). Did you try unplugging and replugging the Nexus 10 or trying another usb port? As soon as you connect the n10 to the pc, drivers will automatically install and it will show up under my pc. Also, if you go to settings - storage, I think you'll see the option of mtp (once you connect it and the pc recognizes the tablet).
PD: Maybe you have issues with the drivers from your nexus phone? You shouldn't since they should be generic, but who knows...

My phone connects fine. In the end, it looks like something broke in Windows. I did a clean install and it recognized my tablet again. But, I still don't know what broke it.

Back when I was on Windows, I did notice sometimes I'd have to uninstall the ADB driver completely for MTP to show properly. No idea why though.
Works great on Ubuntu though, right out of the box too on raring

Cannot connect through Android File Transfer on Mac

For some reason, when my Nexus 4 with stock 4.4.4 (rooted with TWRP) is connected through USB cable to my Mac desktop with Android File Transfer, the connection cannot be established. The message says:
Could not connect to device
Try reconnecting or restarting your device
The strange thing is that 1) I can connect to my Nexus 4 through adb with no problem; 2) I have no trouble at all connecting my Nexus 10 with stock 4.4.4 (rooted with TWRP) to my Mac through Android File Transfer. Anyone know what could be the issue with my Nexus 4?

Have you checked if it is using MTP instead of PTP? MTP is the correct option to use with Android File Transfer.

Few things come to mind.
1. go PTP and then return to MTP
2. Disable USB Debug and re-enable (or enable then disable, if that suits better your situation)
3. "Revoke USB debugging authorizations" also at Developer Options.

My knowledge for in-system solutions has come to an end. I can only think now of (1) cleaning cache and dalvik cache, (2) factory reset and (3) factory restore via factory image.
Are you willing to take this route?
