Android Studio no longer recognizes LG G Stylo - android

I need to know how to make Windows 7 forget it ever connected to my LG G Stylo phone. I have three devices that I use in Android Studio development. For some reason, this one is no longer being detected by the ADB. Something has happened to make it no longer show up, because it did a couple of weeks ago.
AS's ADB will detect my other two devices, and this device shows up in the in the ADB on another computer. I have tediously gone through the registry and removed everything referencing the Stylo, but it still will not show up in AS's ADB.
Thanks for the help!
John

To start, I have just purchased the LG Stylo 3 plus and ran right into this situation. TO repeat the basics you need
With Android Studio shut down...
Turn on Developer options (tap 7 times on build number in settings
(Settings>System>About Phone>Build Number
Turn on USB Debugging in Developer Options
(optionally) check on the type of USB connection, MTP or PTP should
work
(Optionally) Because I did it, also do a revoke USB tap.
Here was the key for me. I needed to install the LG USB Windows Drivers for my Windows 7 (I'll try 10 tonight and update). Go to this page
LG Drivers and firmware
and either type in model number or browse to find device. LG has a nice interface to install the Windows Drivers. I recommend the Support tool to verify the device as the up to date drivers as well. Start Android Studio and to test I just started the app in debug mode and went through the process of setting up ADB for using the new;y connected device.

Developer options" has to be ON in order to make AS see the device
If even though device manager you can't saw the device, Windows couldn't find drivers.Maybe the drivers are hidden on the device otherwise download it and install it.
If that doesn't work:
Shut down
Hit F8 (or whatever gets to startup options screen on your computer)
Disable Driver Signature Enforcement.
Run driver

How to Connect Pixel 2 to ADB

I have a Pixel 2 that is unlocked and has USB debugging enabled. Yet if I plug it into my computer, it only ever shows charging. The USB cord works to connect other devices for data transfer no problem though, so it's not the cord. I have no trouble connecting any other devices to any of my ports, even the original Pixel. I am running Windows 10 pro. The Pixel 2 connects fine to an older computer running Windows 10 pro. I have Android Studio 3 and the usb driver from Google tools. If I go into device manager and click on the Pixel 2, it says I have the most updated driver if I try to update. I have tried disabling and reenabling USB debugging, revoking permissions, etc. Nothing causes it to do anything other than charge. There is no pull-down menu either to select different options.
How can I get my Pixel 2 to be seen by my computer?
I had the same issue connecting my S7 Edge to my MacBook Pro running Android Studio. Make sure that you have the "USB Configuration" setting in the Developer Options to be set to "MTP" ("PTP" on newer phones).
One last ditch effort, a lot of the times when my phone would not show up, switching USB ports on my computer would work most the time. I am very unsure as to why it would, but it would. I thought this was just my situation, but it's worth a try on your end.
Plug cable into device by interchanging upside down. This is hilarious but it worked for me.
I had the same issue connecting my Google Pixel 2 to my Android Studio and this works for me:
Settings -> Connected devices -> USB -> Transfer files (otherwise it's only charging your phone by default)
Settings -> System -> Developer options -> USB debugging (turn this on)
A question prompts up and you need to allow your computer to see your device
lo and behold, my Android Studio can see my Google pixel 2.
My problem ended up being that my Pixel 2 wouldn't connect to my MacBook Pro when using a USB 3.0 cable. It would charge fine, but the mac wouldn't detect it (in any USB Configuration) and the trust device dialog or USB debugging notification never appeared on the device.
Using a chain of cables/adapters that included a USB 2.0 component fixed the problem, e.g. Pixel 2 -> USB-C to USB 2.0 cable -> USB to USB-C cable -> MacBook.
It doesn't appear this problem (and solution is limited to just me
I tried all of the above, several times over the last few months and the only way I am able to get it to work (temporarily) is to reboot my MacBook Pro. It will work for the rest of the day, until I sleep the MBP again.
After my Pixel 2 updated to Android 9, I had to clear the cache of the Media Storage app for my phone to be recognized by my computer / have my phone recognize it was connected to a computer.
My phone has to be plugged in at Windows 10 startup time for this to work.
I connected my phone with USB-C and restarted Windows 10.
In Android,
Search Settings for Media Storage
App info -> Storage -> Clear Cache
Phone prompts me (immediately in my case) with 2 notifications, 1 notification that USB Debugging is enabled (follow steps from this answer), and 1 notification that it is charging.
Tap the charging notification for more options. What I see by default worked for me. I see "USB controlled by: This device" and "Use USB for: No data transfer" (Selecting "File transfer" also works for me)
In Windows 10's Devices -> Bluetooth & other devices -> Other devices, I now see Pixel 2 (Or "MTP" if I had selected "Use USB for: File transfer" in step 4.
The first time you do this, Windows should have sent a notification that the device is being set up (I assume it installs the drivers).
I can now see my Pixel 2 as a connected device in ADB.

For debian/ubuntu only
If you try to use the adb in {your sdk location}/platform-tools/, you will see the message
no permissions (user XXX is not in the plugdev group); see [http://developer.android.com/tools/device.html]
Turns out, you should be using another package with some custom rules of some sort (I have no idea what plugdev group means), and basically you just have to
apt-get install android-tools-adb
and use that adb instead.

Android Studio 2.1.1: "no usb devices or running emulators detected"

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

LG G3 device not recognized by Eclipse on Windows

I recently bought LG G3 and I have enabled debugging mode but Eclipse is still not recognizing it, back when I used the Galaxy S3 for development I had to install Samsung Kies. The G3 drivers are installed and I can see it in My Computer, do I need something like the Kies but for the LG? If so can someone please post a link for that?
See update below
I found the answer that worked for me.
When you plug in the phone, bring down the status shade, pick the USB item ("USB connected") then, from there, pick "Internet connection" -- I chose Ethernet, but I'm not sure the choice matters on the dialog that pops up..
This enables USB debugging to become active; leaving it on Charging, MTP, or PTP does not work.
Once you do this, you can follow #Siddharth's steps to setting the ADB drivers, if needed. (You may need to use the actual LG drivers and not the Google drivers, but once I got this far, it was just like any other phone.)
Caveat
For me, even after going through this once, I still get the "installer" first and then have got go in and choose the "Internet connection" again. But, at least it works.
Update 10 Dec 2014
A recent firmware update has, indeed, removed the "Internet connection" as an option. Instead, PTP now works. I still get the "Connected as an installer" notification every time I plug in the phone and have to click on the notification then click on "Camera (PTP)" -- or wait about a minute. It's slightly better than what It was.
Also note: When this change occurred I had to install the drivers again for the phone, since it comes up as a different type of device when "Camera (PTP)" is chosen than when I used the "Internet connection" option.
For me, this has solved the problem: simply go to LG's website, http://www.lg.com/us/support/software-manuals, select the model (I have selected 'D850') and go to Software Updates tab where you can download the driver. I have installed it and then Eclipse recognized my device. I'm working on Windows 8.1, by the way.

After a lot of searching and trying all solutions still I couldn't connect my LG G3 to eclipse on mac. Finally I find this solution, it works for me hope for you works too:
Install LG USB driver for mac
Go and enable developer mode in your G3 (Setting->About phone (in General Tab)--> Software information --> Tap 8 times on Build Number) then you will see the message which says the Developer option is enabled
In this step you expect that after connecting your mobile via USB cable, the Eclipse detect it
But for me it didn't happen
in this step you need to go (Setting--> Developer Options--> and turn off this option from above green (on/off) switch then again switch on this option from same place (If you don't do this step the "USB Debugging" mode will stay fray and you can not enable it)
In Developer Options menu scroll down until find the "USB Debugging" then tic it and enable it.
almost finished , you should back and configure running mode for your application and see the G3 in your connected usb devices
Try this solution :
Right click on My Computer --> Properties --> Device Manager
Right Click on your device --> Update driver software
Click on "Browse my computer for driver software"
Give path of your android sdk like "D:\Android_Sdk\sdk\extras\google\usb_driver" and tick "Include subfolders"
Click
Now repeat the steps till "Browse my computer for driver software".
Then click on "Let me pick form list of device drivers on my computer". Click on the first option and click next and then click yes. Drivers will be installed for your device.
Hope this helps.
Change the USB mode to PTP and you will get the RSA prompt.
Within the prompt, select allow it > ok and you are done.
This worked for me when I had the same problem on a Mac computer.
To contribute to possible solutions for this fix: I am using an LG G3 on a Mac.
In my case, ADB saw it as a device when I checked, and the Mac showed the device information in the System Information window, yet Eclipse did not see it. I also did not get the RSA confirmation pop-up when I connected the device through USB.
To fix, with my G3 connected, I selected the USB PC Connection (either from the navigation bar or through the settings) and changed it to be Send Images (PTP). Once this was on, I was given the RSA pop up and Eclipse recognized the phone in the Run Configurations window.
If you have this problem on Ubuntu; here is what I did to get it working:
Switch to PTP from MTP on the phone (this assumes you're connected via USB)
Disconnect the USB cable
Go to settings -> developer options and select revoke usb authorizations then ok
Make sure USB Debugging is checked
Reconnect the USB cable and your phone will say its connected as an installer; wait a minute or three and debugging mode should appear on the status bar (on the phone)
Open Eclipse and go to DDMS
Select "reset adb" in the dropdown if your phone isn't appearing yet
Working on Windows 7. All of the solutions from other sites didn't help (i.e. restarting adb and switching between MTP, PTP, Charing). In the end, I found this article (http://www.technobuzz.net/install-lg-g3-lg-drivers-windows-mac-usb-adb/), which contains links for the necessary drivers for the lg g3 (and some others I think). This did the trick and made the RSA key fingerprint dialog appear finally. After confirming, adb and eclipse recognize my device perfectly!
I had this buggy error with my LG Optimus L3 phone connecting to Win7/8 machines!
Cause: Device Driver was missing as it seemed at the end when I fixed it!
How to Fix:
Search through web (using Google) "LG < Your_Phone_Model Number > Drivers Download".(Ex.:- Go to About phone in your settings list > Model Number, for me it's LG-E400f)
Mostly the first few links are related to the required Device Driver download page.(Ex.:- for me I got the following link and for each device driver LG or most of the other vendors/manufactures have that kind of a Manuals and Drivers Page) Visit that page mentiioning about software update and drivers downloads.
Scroll down to the section of "Manuals and Software Update" and doing just the Step 1 was enough for me, which is "Install the USB DRIVERS "
Download it(for Mac or Windows) > Install It > Check Your Eclipse ADT > and it should be visible under Devices tab by now
Cheers!!!
Hope this helps to someone else to clearly get to the solution!
it seems that Eclipse shows the offline mode for lg G3 and some newer devices
and there is no way no use these devices for ADB debugging
there is a way
I am using windows 10
1- download this 11 MB file < http://dl2.uncox.com/android/upload/platform-tools-v22.zip>
2- then go to the directory that you installed the SDK
3- extract the zip file in to the platform-tools folder , override all files(click yes to all) be sure that Eclipse doesn't running
4- open Eclipse and select your android device that stands in devices tab at the right-top corner of your screen and then you can see the arrow near the screen- capture icon and you will find the reset-ADB. click on it ,after that your phone will ask you to allow android debugging for your device click on it
5- congratulations .now you can see that your device shown online
i hope this will help .sorry for my english
I also had a great deal of trouble when attempting to debug android applications on my shiny new LG G3. What ended up working for me was first installing the default google drivers onto the G3 and then following the process detailed by #lilbyrdie.
The process of installing the google usb drivers is very nicely gone through here.
However, with the most recently pushed android update to the G3 there are no longer the options for internet connection or charge only; but they seem to have fixed this defect forcing you to make this odd choice to enable debugging. The only options remaining are MTP and PTP, but if you pull down the notification drawer, choose the 'USB connected' notification (assuming the device is connected to your computer via USB of course) and from there click on 'Media sync (MTP)' even if it is already selected then debugging should be enabled.
Android can't update on the fly the developer mode. So, after turning on developer mode (and given you have the latest driver) switch the green button(under settings->general->developer options) to off and then back on. Then turn debug mode on (after that windows recognizes a new device) and you should be good to go.
In my solution for Windows 7 was helpful to update Android SDK Tools to latest version.
ADB Single/Composite values for LG G3 phones -
I found it was necessary to update (~userName/.android/)adb_usb.ini file with the line 0x1004:
# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x2207
0x1004
In addition, I needed to add the following entry in (.../sdk/extras/google/usb_driver/)android_winusb.inf:
;
; Android WinUsb driver installation.
;
...
[Google.NTx86]
...
;LGE Android Phone
%SingleAdbInterface% = USB_Install, USB\VID_1004&PID_633E
%CompositeAdbInterface% = USB_Install, USB\VID_1004&PID_631D&MI_00
%CompositeAdbInterface% = USB_Install, USB\VID_1004&PID_631D&MI_01
[Google.NTamd64]
...
Oh, and set USB to PTP as well as turn-on USB debugging.
When you're all done with the file modifications and several passes at installing the drivers (ref. earlier posts), you can verify your phone is ready via the Device Manager. It will list your phone as "Android Device"->"Android Composite ADB Interface". I believe an earlier post explains setting up the drivers

Eclipse not detecting my Galaxy S3 GT-I9305 in list of devices

I know this question has been asked numerous times, but none of the threads have had an answer to solve my problem. It seems no matter what i try Eclipse just wont detect my phone, I have set it to debug mode in the settings, i've installed "Kies 3" on my laptop and it says i have the latest drivers already installed on my phone when i try to update it.
I've installed the google USB driver package from the sdk manager and have downloaded and installed the samsung driver from the samsung website. Windows recognizes the device and in the device manager under android phone it appears as "SAMSUNG android ADB Inerface".
Im running windows 7 and have even tried deleting all the mounted dive drivers from regedit as i seen suggested in another thread but still no joy! Really starting to get frustrated with this at this stage i've been trying for two days now to figure this out!
This is such a pain! I need to be able to debug on my phone too as i'm using features that the emulator can't handle (i.e. audio recording). I'm all out of ideas here so any help would really be appreciated!
Thanks
The method I followed to install my GT-I9300 drivers was this:
Download samsung drivers from this link:
http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
Then just connect your phone and make sure you have a stable Internet connection: It will download required drivers automatically.
Also, make sure you have enabled Android developer options in your phone settings. Enable USB debugging in developer options.
I usually get it to work, when I switch the USB mode in my smartphone (e.g. MTP to PTP). This way, windows starts downloading more drivers.
1) Try disconnecting device from PC, revoke USB Debug authorization from settings menu, and then re-authorize the computer you are working on once you connect it again.
2) Check to see if you see the phone in DDMS perspective (left hand side) - if so, try clicking on it and it should work.
3) try removing all drivers (Google, Samsung etc.) + scan "leftover" registery entries using a reg cleaning program. Then install ONLY Kies Light version and try again.
4) It once worked for me - try changing the USB cable (preferably, to an original one)
Let us know if something worked!
1) enable USB debugging in your phone's settings.
2) ensure that you have the proper drivers installed.
3) open adb in command prompt and run "adb connect"

USB Debugging: How to revoke the "Always allow from this computer" option

I've started developing for android. I'm using different computers with different operating systems. (A Windows desktop PC and a Macintosh at home and a Windows Notebook at work)
Most of the time I am using my desktop pc for development but since yesterday my Nexus 4 is displayed as offline in the Eclipse ADT Devices view. This problem only occurs on my desktop pc. On the other computers I don't have any problems getting the device online in eclipse.
I already tried a lot of things like:
- unplugging/plugging the nexus 4
- switching off/on usb debugging
- restarting computer, nexus 4 and the adb server
- reinstalling nexus 4 usb drivers (I'm using the Android Composite ADB Interface Drivers from the Android SDK)
I was about to give up but then I remembered something. After connecting the nexus via usb the "Allow USB debugging" dialog shows up and on my desktop pc I checked the "Always allow from this computer" option.
My hope is that disabling this "Always Allow"-permission could help to get my device back online. I already searched in the developer options to find a way to reset the "Always Allow" permission without success. Maybe it is possible to reset the permission by clearing the data of the App/Service (Settings->Apps(All)) which stores this information but I didn't find the name of it in Google.
So does anyone know the name of the App/Service whose data has to be cleared to reset the permission? Or is there another way to get the device back online that I have not tought of?
You can use your device with multiple computers with that enabled as well. I can use my Nexus 7 and Galaxy Nexus, both running 4.2.2 and having checked the always allow option on 3 machines right now.
Make sure all your machines are running the latest update for ADT and the SDK Tools, as the adb in the previous versions does not support the 4.2.2 security measures. One of my machines had the same problem, and it got fixed when I updated my tools.
Also, sometimes you have multiple Eclipse installs (I have about 11, for various reasons). If all of them aren't updated with the latest tools, make sure your PATH points to the adb in the newest update, and not any other.
