I'm pretty new to android studio and app developing. I ran into some problems after installing android studio and I don't have any solution yet after a day's google search.
I'm using windows 7 system, 32 bit.
1, my Preview panel doesn't show a phone layout (nexus 4, 5 etc.)

2, after I click the green RUN button, it will show: waiting for device to come online and get stuck there.
Could anyone help me solve this problem please?
Perhaps your device hasn't installed correctly. Go to device manager, uninstall your device and then re-install it. Make sure your device allows debugging.
In Hololens Emulator with Windows 10 Pro, I can only use keyboard strokes and my mouse is not recognized. How can I turn on mouse input? I did nothing to connect my keyboard, so why is it with a mouse that I have to change something?
One problem that may solve it: make sure when using the emulator that in Package.appxmanifest in Visual Studio the MaxVersionTested line is the correct version. I was looking at an older version which everyone says to use: 10.0.10586.0 which was incorrect. When choosing the device for debugging, the version will be in the name. Currently, the most updated version (that I am using) is 10.0.14342.1018. After that, start debugging and run the emulator and you should have keyboard and mouse input!
I had the same problem, but I'm not sure how I solved it. Here is what I have done:
Installed Update 3 for VS 2015. Tried again without restarting the PC and got the same problem. On the next day I started the HoloLens Emulator directly via Hyper-V Manager. After that I started my project in Visual Studio. The Emulator loaded correctly and now the Human Input and Keyboard and Mouse Input buttons are enabled.
Update: That was definitely not the answer, but I found a working solution here:

Just put off your proxy in IE and the icons will be enabled. I could turn my proxy on again and the controls remained active.

Cannot see Nexus 6P for debugging

Closed 4 years ago.
I am struggling to figure out the problem with my device not being recognized in Android Studio. However I do see it from file explorer and can browse the device files.
OS: Windows 10
Device: Nexus 6P
Yes, I did some research before posting this question, so I'll enumerate what I tried:
Enabled USB Debugging
Installed Google USB drivers from the SDK manager
Intalled HiSuite(apparently including some device drivers)
Switching between MTP/PTP
Restarting Android Studio several times
Restarting my computer several times
Every USB 2/3 ports of my computer
Tried updating drivers from device manager(however it did not suggest anything)
adb kill-server / start-server
Any suggestions would be greatly welcome!
Thanks in advance!
Apparently, installing 'Google USB Drivers' from the SDK Manager doesn't actually install them!
You have to go to:
'C:\Users\your_user\AppData\Local\Android\sdk\extras\google\usb_driver\'
right-click on 'android_winusb.inf' and install.
Try to use ADB over Network but it depends what Android version you have.
In Developer options you should see ADB over network section if not then sorry for this unhelpful advice.
check for SDK platforms in Android Studio whether you have installed the Android 6.x(N), Because Nexus got Android N updates, so it may be one of the issue you faced...
When I had this problem what I did was install the drivers manually. What you do is download the drivers from the google website NOT with Android Studio then you go into device manager and right click on your nexus. Then go to drivers tab and hit the update then manually find drivers on computer. Navigate to the downloaded drivers and click on them. Device manager will install your drivers and should fix the problem. Also for drivers you may want to try this or this driver Also please post these kinds of questions on the Android Stack Exchange Thanks!
If you have already tried all those steps , i would like you to install pdaNet software . This will automatically detect and repair the driver and you can find device in Android Studio.
This has worked for me
SO references :
Android studio doesn't list my phone under "Choose Device"
eclipse or android studio not recognize my phone on usb debugging mode
References for installing the drivers and enabling USB debugging is available here for reference , you could cross check with as well.
Reference 2 : Installing pdaNet
First of all I make sure that I've installed google's usb_driver. Either through the SDK or what SlashJ said:

You have to go to:
'C:\Users\your_user\AppData\Local\Android\sdk\extras\google\usb_driver\'
right-click on 'android_winusb.inf' and install.

After that's done:
Insert your device into your PC
Open device management
Click start > run devmgmt.msc
Right click my PC > manage > devices in left panel
Check if there's a tab android device and look for your device or an ADB Interface, Otherwise just search for your device
Right click your device and Update Driver Software
Browse my computer for driver software
Let me pick from a list
Search for google or android in the left pane.
And select ADB Interface in the right.
Continue installation and it should work now.
You can try to unplug and re-plug your android device.
Maybe you also have to enable developer mode on the device.
Here's a walkthrough
I have a similar problem with my Wiko phone, I had installed the wrong usb driver and I could not do it manualy.
In developer mode, enable the usb debuging
Try to update your driver with apk installer for Windows 10 even if it is already installed:
APK DRIVER
This tool permits to install automaticaly the right driver.
Have a look to my previous question fo further details:
How can I run my ionic app on a physical device (Wiko phone) on Windows?
i just have that problem and anything works for me
what help me is to click a lot of time on the build number (setting-about phone-build number) and magic happens :)
Did you check in Android Studio Run tab->Edit Configurations->Target set to USB device.
if that doesn't work, try updating Android Studio, and/or device's firmware, also here is a similar question, involves a nexus and windows 10: https://stackoverflow.com/a/31938193/3817308
I hope this help.
I'm not sure how you installed adb driver. If your device is displayed in device manager but not as a ADB device, try these steps
Go to Control Panel and open Device Manager.
Find the device
Right click the device and select properties.
Select Driver tab, then click the Update Driver button.
Choose Browse my computer for driver software.
Let me pick from a list of device drivers on my computer
Browse for the .inf driver file. Open and Next.
Select ADB interface from device list (i can't remember the exact name)
Install
There's another another Stack post (Cannot see Nexus 6P for debugging) you might want to try.
You need to manually download the driver here (http://developer.android.com/sdk/win-usb.html)
Go to "Devices and Printers", right-click on "MTP", and choose properties.
Click "ADB interface", then click "Properties"
Go to "Driver" tab and update driver with the file you just downloaded. (Make sure you unzip them first)
When I select any emulator, I'm getting this weird old red phone. The screen is super small and I can't see anything. I've tried searching, but it looks like no one else has had this problem. Does anyone recognize it? My emulators did work fine, but I had to uninstall and reinstall Android Studio because it broke. After reinstalling, this is what's happening :/
Open AVD Manager in Android studio
Select the target emulator and click edit
Click Show Advanced Setting
In the Boot Option section select Cold Boot
Click on Finish
This solved my problem
Go to Tools>Android>AVD Manager and remove all device than add again. Hopefully this will fix your problem. I had exact issue when I moved my sdk folder.
You can try genymotion as your emulator. Its faster and more stable than android studio's emulator. Search on Google for more information.
I had the exact same problem.
I removed all existing devices from my AVD manager and re-installed one which is required. The problem went away.
I want to develop for Google Glass with Android Studio. I'm really new to it. When I connect Google Glass to my computer over USB, Android Studio does not recognize it ("no connected devices").
Android Studio recognizes when I'm connecting my mobile over USB, and my computer recognizes the glasses, but Android Studio cannot find the connection to the glasses. I of course enabled debugging on the glasses, and it's connected to my mobile. What am I doing wrong?
I had the same issue. I posted about it earlier this year on the Glass Explorers forum to ask for some help. I got a couple of responses, tried them, and this is what worked for me, posted by Kevin
"Are you running Windows? If so open the device manager and see what Glass is listed as, if it has an exclimation point right click and update driver software choose to search your computer for the driver and point it too the sdk>extras > google_usb folder (assuming you have updated the drivers in the sdk manager recently.
After this is done reboot the pc plug your Glass in let it install the drivers and if it is working properly you may get a prompt on Glass to trust this computer for debugging.. If this didnt work.
Go back to the device manager, glass should now be listed as an android adb device. Now click on this and choose to update driver software, then instead of pointing the the google_usb folder, click on the part below that "let me pick from a list of device drivers on my pc.." When you do this choose composite usb device and then it should recognize the Glass in adb. "
I hope this helps.
EDIT:
Another thing to try:
You need to make sure that you have the right drivers. The issue for me was that I needed to open the SDK manager and download the USB Drivers - go try that.
