Android Studio doesn't recognize my device

Question

Here is the problem. I want to run my Android Studio apps on my device (Samsung Galaxy Ace 2). But nothing works for me. Tell me what I've missed:

1) USB debugging is on

2) ADB driver is installed (in device manager i can see Android Composite ADB Interface)

3) ADB device list is still clear, even if i reset server(adb kill-server, adb start-server, adb devices - list of devices is clear)

4) in google usb driver directory, in android_winusb.inf file I added my device identificators

5) Android device manager still cannot connect to my device, showing this error when I reset it: "adb connection error an existing connection was forcibly closed by the remote host"

So I will be glad to hear any advices. Hope you'll help me

So, you've downloaded/installed the device's drivers on the machine? — ChiefTwoPencils, Aug 08 '14 at 09:04
Some times you need to add device interface id into your_username/.android/config file. — Tugrul, Aug 08 '14 at 09:05
Yes, I downloaded Google USB driver and then replaced my Samsung driver with it — Red Hot Chili Coder, Aug 08 '14 at 09:32
Tugrul Asik, there is no such file in .android directory on my PC — Red Hot Chili Coder, Aug 08 '14 at 09:34
On windows, make sure "ANDROID_SDK_HOME" variable is pointing to your SDK. — BubbaGum, Nov 07 '14 at 18:53

Did you try to configure the "Media Mode" in "Camera (PTP)" instead of "Media device (MTP)"? This is sometimes solving the issue. Its in the USB Computer Connection options of your Android device, you should see an "authorize" dialog then.

Update 04/2017: looks like it has been fixed in Android 7.1.2

Unfortunately, I can't change that mode. I searched how to do that, but according to some sources there should be a chooser dialog, where you can choose MTP or PTP. But there is no such option on my device. Do you know another way to do that? – Red Hot Chili Coder Aug 08 '14 at 09:26

My device works only in MTP and i can select that from the notification area, you can also try the "Universal ADB drivers" https://github.com/koush/UniversalAdbDriver – FrankMonza Aug 08 '14 at 09:31
Yes, it helped some way. Now I have something really strange - Android Composite Adb Interace (my device) and it's clone Google Galaxe Nexus ADB Interface (also my device). But unfortunately Android studio see none of them – Red Hot Chili Coder Aug 08 '14 at 09:55

This worked for me too. My phone is LG G4, and after I switched to PTP rather than MTP and replugged the cable, "Install PC drivers" screen showed up no the phone and I clicked on "install" then made the installation on computer and I "authorized" for debugging.. That's it.. – Orhun D. Oct 10 '15 at 15:45

I have done numerous ways of handling that issue. Finally it has worked! I am using LG Optimus II, but I believe the following steps are generic to other Android devices as well.

Step 1:

Make sure your device is enabled for development. If yes, go to Step 2, otherwise go to Settings > About phone and tap Build number seven times which is magic number :-). Now Developer Options is available in the Settings.

Step 2:

Before you plug your device to PC, Go to Settings > Developer Options and select USB Connection method.

Step 3:

Plug the phone to the PC, you are given options for the USB Connection method, and please select Internet connection. Make sure you have connected to the Internet. By the way, I have changed MTP to PTP, it did not work for me. Therefore, I tried Internet connection mode, then it worked.

Step 4:

Run the app in the Android Studio, it will ask you to authorize the device for development, and select YES!.

Step 5:

Run the application via Android Studio and choose the device, not emulator, and BINGO! Welcome to Android development board.

I simply installed correct adb drivers from http://adbdriver.com/. I looked at devices in windows manager and found that it couldn't install it on it's own. This helped me. — Simon Guldstrand, Nov 18 '16 at 12:09
After an hour reading on stackoverflow THIS was the ONLY solution, THANKS! (updating drivers via abdriver.com) — Goty Metal, Oct 05 '17 at 20:42

Try swapping the USB port the cable is plugged into.

Sounds crazy but after 20 minutes of debugging this worked for me.

Sometimes swapping the cable might help too. I once had a USB cable that wouldn't work for debugging but only power. – AdamMc331 May 22 '15 at 18:14

I also tried above solutions but got no luck. So here's what I did:

Download and install PdaNet+ to fix connection issues between my computer and android device
Enable USB debugging on my android device
Unplug the phone and plug it again after it's installed
Run my app and voila! My android device is now recognized by Android Studio

Solution for those working with Huawei phones - You will get this error when ADB interface is not installed. Check if you have installed Huawei HiSuite. USB driver gets installed when you install HiSuite (I suppose this is true for most of the new phones that come with a Sync Software). If the ADB interface is installed on your computer you should see 'Android Composite ADB Interface' under Android Phone in your Device Manager as shown in this picture.

If you have Mi Device than you need to enable this two option after enabling Developer Mode.

USB Debugging (Enable = True)
Install via USB (Enable = True)

See this screenshot.

LG Optimus Zone 2 pp415 d\n connect in mtp, but does work in internet connection mode. Lost lots of time messing with it. There's no doc for this, but I'd suggest trying all 4 of the connection options. Only 1 that works for me is Internet Connection->Ethernet, then win 8 auto-detects a driver and installs it. In MTP mode despite all drivers being registered with device manager, adb doesn't pick it up.

No need to apologize. It seems my answer regarding swapping USB ports still receives regular up-votes. Maybe set it as the accepted answer as this still seems to be a very real problem for Android Studio developers. – Nick Sarafa Apr 15 '16 at 21:14

In my case it was due to already running and hanged adb.exe on another user under my PC. I had two users on my PC, the second user had the adb.exe process hanged even when I tried to end the process. It worked with me after (End Process Tree) from the Task Manager.

Hope this will help someone with multiple users :)

In addition to the above configurations, I had to set deployment target to "Open Select Deployment Target Dialog", run once (choosing my device from the options listed), and from then on Android Studio was able to see my device even after changing the deployment setting back to "USB Device". My SWAG is that since Android Studio uses its own internal cache to find your device, it has to be initialized first.

For me, this ended up being because I had the wrong SDK level installed (new version of Android Studio installed the SDK for Android 10, whereas I have a device that runs only Android 8.1). While Android Studio would "recognize" the device and display a string in the "devices" menu instead of just saying that no device was connected, installing the right SDK level for my device ended up changing the string to something recognizable (my device's model name) and allowed me to actually run my app over ADB.

I had a big problem with my Samsung S10 Plus as it was not detecded by Android Studio on my Macbook even if I did all what is required to be detected, that is to say:

Enable developer mode (7 taps on Build version in Android settings)
Enable USB debugging

What I did is to start "Android File Transfer" on my Macbook and the magic happened. A popup appeared on my device asking if I want to authorize an USB access to it. I clicked "Yes, always" and now Android Studio can detect my device on my Mac :)

If you've got developer mode set up on your device & usb debugging set to on, then don't be surprised if SEVERAL different usb cables are all to blame! I tried to find the problem for ages, then tried a third usb cable & my MacBook recognised the device straight away. The phone shows it's charging with all 3 of them but only the one works for data transfer.
