I installed the Android 2.2 SDK (2.2 is the version i have on my smartphone). I've tried running the NotePad sample project as an Android project. Here is what happens: the emulator loads, but when I click on the app, the screen goes blank. There are no errors being thrown. Has anyone else run into this problem? If so, how have you fixed it?
When you press run, the emulator loads AND the application should automatically open and run. Also, make sure there are no errors with the code itself.
If all else fails, try a new/ different SDK and make sure the app has no errors during it's installation into the SDK. Look at the Console and LogCat to make sure that there are no errors the emulator runs.

After installing everything it couldn't create emulator. Running emulator from android studio. Using a Hello world Xamarin app. It installs on the emulator successfully but stops after showing a white screen. Then closes automatically showing this error:
Couldn't connect debugger. You can see more details in Xamarin Diagnostic output and the full exception on logs.
Manually opening the app also fails to show second time but opeing it third time shows the UI that has only a label and a button.
Third time it works. Also closed android studio so that theres no conflict on debugger.
Now what is wrong here?
Clean and Rebuild the Solution Is working fine for me, also in some cases you need to uninstall the app from Device.
I got the same problem after updating Android Sdk from Android Studio, then Visual Studio showed that error. A restart will help.
I hope this should mainly because of the device connectivity, so I change the cable and the issue was solved. 😀
Doing a factory reset on my emulator device via Android Device Manager fixed this for me.
I've been working on a Xamarin project for a few days and have been testing it fine, but today it has suddenly stopped allowing me to debug the app, either via Live Player, or by connecting my smart phone via USB.
The only error I am getting, as far as I can see, is
Failed to debug your app
I've not got a way of testing it on iOS devices, but the built-in Windows Phone emulator runs the app fine, albeit with an error in my code popping up now and then.
What could be causing the Android version to stop debugging, or how do I at least fix it?
There are a couple of steps that can help with that issue:
Clean the solution and exit visual studio
manually delete the .vs folder in your solution directory
Delete the /obj and /bin folders in your shared code, and in each project for the platforms you are using
if you are developing for iOS, sometimes it helps to restart your mac
Start Visual Studio
Rebuild your shared code project
Rebuild every native project
Beyond that also make sure that you are using the latest versions of Visual Studio, Xamarin and Xamarin.Forms on all your computers, and that the nuGet Packages your project is using are at the very same version each in shared and native code
Also check, if your app isn't throwing an unexpected exception during its initialization. Especially if not caught, it can happen that your app crashes before your code gets executed at all.
In addition you may find further information about what is going on at Help -> Xamarin -> Open logs or in the device management in XCode (iOS only)
Try this :
Close visual studio if open.
Open App Data and then go to
(a) Local\Xamarin
(B) Local\Xamarin\Xamarin.Android
Empty these folders.
Open your project and then try to build your application.
Not a proper solution, but I uninstalled and reinstalled Visual Studio. This seems to have fixed the problem, but I've still no idea why it stopped working in the first place.
Since yesterday, my android studio emulators don't start. It was just after i updated Android Studio Library, i don't know if it is just a coïncidence.
What happens when i press start is:
The emulator command is executed
I see emulator.exe process in windows task manager, but no window is opened
Before that, the emulators started just fine, i had no problems, so it shouldn't be hardware issues.
I tried to launch it from the command line, to see if there were errors, but there's nothing. I also checked android studio's logs but still nothing... I also reinstalled completely android studio with no effects. I also tried to let it run for awhile but nothing appears.
Does anyone have a clue about what could cause this ?
EDIT :
It was a known issue (GPU related) of the SDK Tools 25.1.1 , it has been updated about 5 days later and now it works perfectly.
I had exactly the same issue.
Removing C:Windows\System32\Wbem from system PATH variable helps me:

I recently installed Android studio and the first time around AVD worked fine and the emulator was up and running no problem with that. But when I turned off my computer and booted it up again. But now when i try to open avd the following error message is displayed
when i reinstalled the android studio the same thing happens again,for the first time around it works but second time around the same error message comes.
Not able to find solutions over the internet as well.
This is a common problem that many people have faced. The Access Denied is indicating that Android Studio is trying to access files that require elevated privileges.
To solve this error, right click your Android Studio launcher, and click Run as Administrator.
I am new to Android development and Eclipse. I have been given an Android app and asked to make some simple changes to it. I can build the project and run it in the emulator, but I see some errors in the LogCat window in Eclipse.
I put aside the app I was given and wrote the Hello World app, following the Hello World tutorial on developer.android.com. With this simple app, I was surprised to see many errors and stack dumps in the LogCat window. I closed Eclipse and re-launched it. After waiting for Eclipse to finish initializing, LogCat was empty. Then I started the Hello World app by clicking the run button. After a while entries appeared in LogCat, including many errors.
With such a simple app, copied from the tutorial, I am guessing the errors arise from the development environment and/or virtual device rather than from the app itself, but I would like to be able to run apps without errors.
Is it a reasonable expectation to be able to run Android apps from Eclipse on an AVD without any errors? Or is it the state of the art that the development environment logs many errors and dumps stack traces even when everything is running "normally"?
If it is reasonable, I will pursue each error until I have cleaned up my environment and application. I would prefer this, as I would then know that if errors appear as I continue development, they arise from my application and must be fixed. On the other hand, I can't spend months developing Eclipse and the Android SDK. If I have to learn to live with logs full of error messages, I'll just ignore them unless something crashes.
Note that the Hello World application runs as expected - it appears to be working despite the errors.
I am running Eclipse Indigo SR2 and Android SDK ??? (I don't see a version number for the SDK - the installer is r18 and SDK Manager says there are no updates available) on Windows 7 Professional, 64bit. I am testing with Android 4.0.3.
Use either:
adb com.your.package:v
or in log cat on the side button (You may need to make this visible by pressing the button with two rectangles in it in log cat) press the plus button and then add an application filter
