Problem Picture
Hey guys. I just installed to flutter and android studio. So, I new installed to emulator. I started to follow a tutorial and in there, instructor's emulator's name was in the devices label but mine is not like it(it says no devices.As i show in picture). Also, when i was click over devices button I can open my emulator. My question is, can my emulator work as manuel, with my manuel click or do you have any advices for me about this? Thanks in advance.
When you start your emulator for the first time, you must authorize your computer to access it by enabling the USB debugging on it in the Phone Settings and by changing the Use USB for to Transferring files
I am sort of lost on where to find the Tools Menu in Android Studio.
According to this link https://developer.android.com/studio/run/managing-avds.html, I do not have to run an Android Studio project in order to launch the AVD Manager.
Currently, I am on Android Studio Version 3.0 Beta 6.
I would like some guidance on where the Tools Menu is located in which the link above mentions. Pictures would really help and are much appreciated.
While you do not have to run a project to access the AVD manager, you cannot access it in the welcome screen. You must first create or open a project and then you should be able to find what the link is referring to.
I'm using Android Studio on a Windows 10, and I'm trying to run an app I created. The emulator starts up with a black screen and then the word android pops up, but then nothing happens. I know other people have posted about this topic, but none of the solutions work. I don't have an actual phone, so I can't plug it into a real phone. What should I do here? Thanks in advance.

It's a much better emulator than what comes with Android Studio, and it should work. In fact, Google even has plug ins for it because they even admit it's much better.
I'm having real trouble when I try to use the IOS emulator from the visual studio. So I created a hello world app in VS using xamarin (latest stable version), I set the project as main project, and When I refresh the connexion with the mac, I can't select the device that should be shown in the selectList. The message is "No device attached" :
And if I try to use xamarin studio on the host mac, all is okay, the sample app builds on the iphone emulator:
Thanks to help me !
I know this question has already been answered, but i found it when i had a problem, and it did not help... but i did find the solution:
Under the debugging menu in VS2012, click on Configuration Manager
make sure that iPhone Simulator (or iPad, if you want) is set...
Default seems to be looking for a physical device...
hope this helps.
Are you sure the device is connected to the Mac and not the Windows machine? Have you tried debugging from that same device from Xamarin Studio on the Mac?
Had the same problem. Issue was when i loaded my solution, visual studio 2012 decided to choose a library project as the 'Startup project'.
Rt Clicked the ios project, chose 'Set as StartUp Project' and the device list was populated.
P.S: Visual Studio you should be old enough to figure this out by now.
When I ran into this problem, I had another instance of visual studio running which was connected to the Mac.
Apparently you can only have on VS instance connected at a time.
Check your server log in Visual Studio output window for some more clues:
Closing the other instance of Visual Studio allowed me to connect in the instance I wanted to debug in
I discovered something missing. For me, in Visual Studio 2013, for some reason they have removed Solution Platforms from the toolbar. This makes it impossible to switch from iPhone to iPhoneSimulator without opening Configuration Manager. So, to fix this.
Click TOOLS/Customize then select the 'Commands' tab then select the 'Toolbar:' radio button and click the dropdown to the right of it and select 'Standard' as the toolbar you're working on.
Now, click 'Add Command' and select 'Build' from the catagories on the left and then scroll down commands until you find 'Solution Platforms'. Select that one and click OK. Then click the 'Close' button. You will now see an additional dropdown next to the Solution Configurations dropdown on your Standard Toolbar.
This will allow you to easily switch from iPhoneSimulator and iPhone. Use iPhone when you want to plug in an actual device, and use iPhoneSimulator when you want to pick a simulated device.
Hope this helps somebody out. I too have spent lots of time trying to figure this one out when I went from a device and was trying to use the simulator instead.
Restarting of Visual Studio 2010 worked for me.
Different things worked for me (Windows 8.1 & Visual Studio 2013):
Restart Visual Studio
Set 'iPhoneSimulator' as platform (only working one)
In Properties - iOS Application change 'Deployment Target' version to some lower number (6.0 worked for me).
As well as checking you have the right startup project selected as per #Chamkila's answer, check that you haven't accidentally broken your project's Info.plist file by attempting to open it through Visual Studio.
I just opened a new project in Android Studio, but the preview screen isn’t working. It should show “Hello World!” right now, but it’s blank. When I go to other projects I’ve completed, the preview doesn’t show up there either.
I’ve reinstalled the program and I’m googling ways to fix the problem. If anyone has had this problem and fixed it, or just has an idea of what to do, I’d greatly appreciate the help! I will attach a screenshot of my Android Studio. Android Studio w/ preview problem
Thanks
Have you checked your preview window in android studio ?
I am asking to you because I was also in the same problem a month ago.
If yes, In The Preview Window. There Will Be A Error Symbol On that window.
Tap on that it will show you the reason for preview error. Fix it and now it works perfectly in my pc.
Edit 1:
Exact Solution after your comment
Tap On That Blue Dot
It would tell preview fidelity issue for the session. Mute The Fidelity Issue For The Session From Same Window And You Are Good To Go.
