I just installed VS 2015, the installation was finish (after some fail time caused by the slow network, I run setup again).
I create a project as Android > Android blank project
When I press F5, the build is seem to by success but the deploy is fail, there isn't error message. Tried set Tool->Option->Build->Diagnostic, no result. VS 2015 is pretty new, is anyone met this? How can I fix this?
I bumped into the same, but I started VS2015 as Administrator and solved the problem.
Is any Android Virtual Device running?
Open AVD menu
Launch the device
Wait for it to fully load
Build and deploy
Find your app in device's menu and execute it
Visual Studio gets stuck trying to deploy the app to the emulator or the emulator does not appear as a debug target in other IDEs
If the emulator is running, but it does not appear to be connected to ADB (Android Debug Bridge) or it does not appear in Android tools that make use of ADB (for example, Android Studio or Eclipse), you may need to adjust where the emulator looks for ADB.
The emulator uses a registry key to identify the base location of your Android SDK, and looks for the \platform-tools\adb.exe file under that directory. To modify the Android SDK path used by the emulator:
Open Registry Editor by selecting Run from the Start buttons context menu, typing regedit in the dialog box, and choosing OK.
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Android SDK Tools in the folder tree on the left.
Modify the Path registry variable to match the path to your Android SDK.
Restart the emulator and you should now be able to see the emulator connected to ADB and associated Android tools.
And yet another recipe of fixing this:
clean projects
remove all bin, obj folders
mark your android-project
as startup
then try to deploy again
As for me, in some cases, if visual studio stucked on project building, it requires pc reboot.
I had the same annoying issue. Going to Options -> Xamarin -> Android Setting and checking Preserve application data/cache on device between deploys solved my problem.
I was facing same issue.
Just reopen visual studio and rebuild your project..and then try to deploy.
Its worked for me!
According to Magnus Grindal Bakken's comment, I found the solution.
1) The installation must have an internet connection to be completed.
Any interruption may cause components to be excluded.
2) You need android emulator. Installing the Android SDK and Visual Studio 2015, is not sufficient, You either need the Microsoft emulator, the android one or another third party emulator (like Genymotion). You also need to ensure that the Xamarin plugins for Visual Studio are installed.
Xamarin for Visual Studio can be downloaded here. Once it is installed Visual Studio will be able to create and run Xamarin projects. Xamarin for VS includes the Xamarin Player for emulation. I think it's even better than Genymotion.
Start emulator via AVD manger ... [start] button (as user m93a suggested).
And next option contains check option "wipe user data". Check it !
It helps me solve this problem. Then deploy or debug the application and all process will works as expected.
I had the same problem with my XF App, it didn't deploy and just one message saying Deployment Failed, internal error....
I solved it. Working on Mac with Xamarin Studio, make sure that the ABI of your simulator is supported by your app.
Xamarin Studio Android project Options
Just run your Visual studio as Administrator mode.
Sometimes the physical Android device gets confused about versions.
On the device, to go settings | Applications Manager | All applications.
Manually delete your application.
Manually delete "Mono Shared Runtime" (don't worry it will reinstall during deploy)
Make any change in your project so it is seen as altered and needing to be recompiled: Add a new blank-line to a .cs file or something.
Build
Debug/deploy
I faced that problem couple hours ago, I tried to deactivate hyper-V and it worked for me.
In the Android App project Properties in Visual Studio I had to go to Android Options>Advanced and make sure the Support architectures had the architecture of my AVD checked.
In my case this was x86_64 (which, by the way, does not have a particularly discovereable method of installation - took me days).
First of all, we can find the error in "Details" when we click "Start" button on "AVD Manager" for "Android_Accelerated_x86". If the error is as follows :
Please ensure Intel HAXM is properly installed and usable. CPU
acceleration status: HAXM is not installed on this machine
So, in this case we need to install "Intel® Hardware Accelerated Execution Manager". It can be downloaded from following link :
haxm-windows_v6_0_6.zip (6.0.6)
Note: After installing Xamarin for the first time in visual studio 2015 i had the same error to run "Android_Accelerated_x86". After installing this accelerated emulator is now up and running.
If the emulator does not even lauch, maybe deploy is skipped.
You cas see this in the output console.
If so, you may have to activate the deploy by checking it in the solution's (not project) parameters.
If the emulator launches but the deploy won't end after minutes, with no error, try the steps described here : https://stackoverflow.com/a/32564067/7505268
That solved it for me.
I had Xamarin Android Player opened while trying to deploy the Android project. This steps worked for me:
Closed Xamarin Android Player
Ran Android project again
in my case I had this problem because "Solution Configuration" was set to Release. I change it back to Debug and I solve the problem
Try one of the following and see if you can get the app to deploy to your device.
Clean and build project/solution
Make sure you have updated all the NuGet packages (Right click on solution and click on Manage NuGet Packages.... Then check in Updates section whether there are any updates)
Make sure you have installed all the necessary SDKs from the Android SDK Manager
Check whether you have selected the correct project as the startup
Check if you have set the correct path for Android SDK and NDK locations
Make sure you have checked Deploy for your selected project from Build -> Configuration Manager
Well there can be many reasons,one of them could be that from the Build section in your toolbar,if you check the configuration manager there will be project names that are available in your current solution all you have to check is if the deploy checkbox is checked or not.If not kindly check it and things will work just fine
This worked for me:
Making sure that Define DEBUG constant is checked.
Using Log.Info("yourTag-AnyString", "Error before/after ");
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
Log.Info(tag, "Error before Layout");
SetContentView(Resource.Layout.Main);
// Get our button from the layout resource,
// and attach an event to it
//Button button = FindViewById<Button>(Resource.Id.MyButton);
//button.Click += delegate { button.Text = string.Format("{0} clicks!", count++); };
Log.Info(tag, "Error before variables");
userName = FindViewById<EditText>(Resource.Id.editTextUsername);
password = FindViewById<EditText>(Resource.Id.editTextPassword);
btnInsert = FindViewById<Button>(Resource.Id.btnInsert);
Log.Info(tag, "Error after variables");
btnInsert.Click += BtnInsert_Click;
}
changing emulators or exporting the signed .apk instead
For android apps, using android device logging
There is actually a connection between running Visual Studio as administrator and setting the registry path.
I followed the instructions here but it only worked after running VS as admin because my Android SDK path is in "C:\Program Files (x86)". So in order to add or change files there you need admin rights. Alternatively you can change the permissions of the "Android" folder so that the group "Users" as full access. This worked for me as well.
Or you make sure you don't even install the Android SDK in "C:\Program Files (x86)".
By the way I found that restarting VS, or even the Emulator again wasn't necessary after I added the registry key. It picks it up when it needs to.

I'm very new to Android development and have never used Android Studio before. I set it up, got my app working on my phone and left it alone for a few weeks. Upon returning, I could not find the Android Studio executable on my computer, so I reinstalled it and restarted on the same project.
Not sure if this has to do with the AVD Manager button being grayed out. Things I have tried:
Making sure my SDK path is correct
Running Android Studio as administrator
Launching the AVD Manager executable from windows. I can create a virtual device but doesn't affect disabled AVD Manager button when restarting Android Studio.
Installing Intel X86 Atom System Image and Google APIs in SDK Manager, under API 24.Everything under API 25 is installed.
Any help is appreciated. Thank you!
This generally happens when Android Studio is not able identify the android sdk installation in the machine. This could happen if Android Studio is launched in non-Administrator mode.
Just close and relaunch Android Studio in administrator mode. You will see a saying "android framework is identified" Click on the configure link on that notification. The AndroidStudio will start configuring the android sdk. After some time the buttons would be visible and enabled.
If you tried running the Android Studio in administrator mode and it still do not work for you try the following way.
Delete the .idea folder in the project
Re open the project from going to File->Open Recent->
Then you will be asked to convert the project
Click convert
For anyone seeing this problem following the React Native tutorial make sure to click the "Configure" button in the Event Log next to the log text that reads "Frameworks detected: Android framework is detected in the project"
This action seems to be what configures the project to be an Android project.
I'v solved this issue by updating gradle.
It is simple
The only thing that worked for me was that I clicked in Androidstudio in the top right on SDK Managar.
And there under android sdk it was so that there was no path entered. and it was also so that NO Check box was checked below.
So I had to first click in the top right on Edit thereby was written to me the path pure.
After that I had to select a chack box below it no matter whiche and sometimes it must then just install something. When it has finished installing click OK. It may be that you then have to close and open android studio again.
I was having this issue on a new machine running MacOS High Sierra.
After installing Android Studio and the most recent SDK/
SDK Tools, I was unable to create any AVD from Android Studio (button greyed out, no option under Tools) or run the AVD Manager any other way.
I tried the same things the OP had done, then noticed I was getting the following error: Gradle sync failed: Failed to find Build Tools revision 26.0.2
From the Event Log I followed a link to download the Build tools and now it works!
If you are working on Flutter, Follow the steps:
Open Settings in Android Studio (CTRLALTS)
Search Flutter
Check may path of Flutter SDK is not available.
Set the path and press OK.
Done! Thank you
I tried the answers here, but the only solution for me was to restart my machine and it fixed itself. It happened after upgrading AS (from 4.0.2 to 4.2.2)
in android studio or intellij program:
goto tools > android > SDK manager
click on Edit (android SDK location)
click next and next
close dialog
its ok.
I've started with Xamarin and Android using Visual Studio 2013.
When I start debugging the android app, it builds, deploys to device and then debugging in Visual Studio stops. I can't hit any breakpoint. App is working in device, but I cannot debug it.
Am I missing something?
I've tried various emulators and a physical android device but debugging doesn't work in any of them. It just act like I have stopped it.
Debugging the same solution in Xamarin Studio works, I just can't get it working in Visual Studio.
I was having the same problem and I found this workaround with Hyper-V in Xamarin's documentation: https://developer.xamarin.com/guides/android/deployment,_testing,_and_metrics/debug-on-emulator/visual-studio-android-emulator/
TL;DR; Open Hyper-V Manager -> Go to settings on your emulator -> Go to processor settings -> Select Compatibility -> Mark the "Migrate to a physical computer with a different processor version" checkbox -> Done! (At least for me) VS is now debugging my Android App
Another reason why Visual studio can't debug Android Xamarin app with a Hyper-V is due to you don´t have 'Deploy" option check in android project.
Steps: 1) Enter in "Solution properties" 2) Select "Configurarion Properties" 3) Check "Deploy" in Android project.
Make sure you are running on Debug mode (on target).
Then, check the Properties of the App Project and see if it's using the Xamarin debugger instead of the VisualStudio Debugger.
Enter in "Solution properties"
Select "Configurarion Properties"
Check "Deploy" in Android project.
Open Hyper-V Manager
Go to settings on your emulator
Go to processor settings
Select Compatibility
Mark the "Migrate to a physical computer with a different processor version" checkbox
This will also happen if you don't have any activity marked as your main launcher activity:
[Activity(
...
MainLauncher = true,
...)]
public class MainActivity ...
Easy mistake to make if you're shifting code in from a prior project and the prior project is using a splash activity and your new project is not yet doing so.
Go to property of app project then click android option and checked checkbox in debugging section.then run again.
For anyone who might still need help. Also make sure the build and deploy checkbox's are checked in the configuration manager. .
In my case, after some investigation, I saw I was having this warning: "Failed to read .android.dll' with debugging symbols. Retrying to load it without it. Error details are logged below. 2>Mono.Cecil.Cil.SymbolsNotMatchingException: symbols were found but are not mathing the assembly"
The solution was to disable linking:
Right-click the Android Project -> Properties -> Android Options -> Under "Linker properties", set Linking to None (see image below)
Got this from TedFalasco's answer on this post.
Hyper-V manager can't be installed on Windows 7 (only the management tool gets installed) so if you get this problem, following those steps don't help.
Here is the thing that worked for me and it's mentioned here as an answer but hasn't been marked up or marked as an answer. This is actually the best and easiest solution. nothing else worked for me.
In Visual studio, make sure you choose the solution file (not project files) in the solution explorer. Then go "Project > [project]properties"
in the left pane choose "Configuration Properties > Configuration"
Now check the Deploy feature if possible. Only deployable projects have the option.
This saved my life and I almost gave up on Xamarin. I really hope this helps others like me.....
In my case, the warning was self-explanatory:
Set the debugging information to Portable in the Visual Studio project property pages or edit the project file in a text editor and set the 'DebugType' MSBuild property to 'portable' to use the newer
In other words: Right click on project => properties => build => click on advanced => set the debugging information to portable.
I have tried every answer and none of them worked.
Here is what I did to make it work again:
Plug your physical android device to the computer. Android device must have Developer options enabled.
Choose your android device in Visual Studio.
Run app in Debug mode. Your app should appear on your android device.
Unplug your android device from computer.
Try running your app in android emulator. For me Debug option starts working again.
So just now I decided to switch over to Android Studio from Eclipse, everything seems to be fine except that I can't even find the menu to add a new virtual device.
On the Android dev website it says it should be in Tools>Android>AVD Manager or to execute "android avd" from the tools directory, but I don't have a tools directory.
I installed it with pretty much all the default settings so i don't know how it's not there.
Fixed itself sort of. I tried running a project and android studio had a message come up there that allowed me to install the part that was missing, I don't know why I didn't have it at the beginning though.
I'm Windows 7 64-bit user and I got Android Studio problem after I update the latest version of Android Studio and SDK components..
The following SDK components were not installed: sys-img-x86-addon-google_apis-google-22 and addon-google_apis-google-22
Please help me to resolve this problem. Thank you.
I had the same issue when trying to upgrade Android Studio from 1.1 to 1.2 on Mac OS 10.10.
I solved the problem by selecting custom installation instead of standard. Also we need to select the Android SDK Platform (Lollipop 5.1).
Choose the new UI Design >> next
Just try to cancel the "Downloading Components" from upper right
corner 'X' button.
A dialog box will appear then click OK (wait a bit for first time
launch)
I uninstall Only Android studio (keep the SDK and Emulator) and then reinstall it just android studio. took me 2 minutes and my android studio work again.
I had this same problem, but I'm a Linux user.
I resolved the problem by reattempting the installation with adminstrator privileges. [For those Linux users reading this, I ran studio.sh with sudo.]
I just click 'Retry' and it's ok! Also run on Win7 64-bit.
TRY BELOW SOLUTIONS.
SOLUTION 1:
-> Run Android Studio as Administrator (this is only required for first run or when any issues arise due to automatic updates on any run in future).
Though it shows API 23 is or any other updates are not installed (and wouldn't show any 'Retry' button), BUT still the download and installation of rest of the updates would proceed (you can see the download progress incrementing even after seeing the above errors). So, DO NOT ABORT the operation.
-> At the end of installation (after rest of successful updates are installed) it would this time display the "Retry" button to retry installation for API 23 or any other versions which had failed earlier. Then click the "Retry" button, it would work this time.
This would resolve your issue with successful installation.
-> Next time onward no need to run Android studio as Administrator, unless it does any automatic updates and shows similar issues.
SOLUTION 2:
-> Alternative approach is to install any updates (which ever failed in earlier attempt) from Android SDK Manager first and then later launch Android Studio (which would not need any check for updates and any additional installations).
To install any features or updates, run Android SDK manager as administrator (run as administrator is not mandatory for this but preferred to avoid any permissions related issues) and check the required options and proceed with the installation without any issues.
SOLUTION 3:
-> If still your issue is not resolved, then try the proxy solution as suggested by others or check your internet connectivity if it's working properly or not.
*Any of the above solutions should resolve your issues.
go to c->users->[Your user account]-> remove android 1.2 and restart the android studio
when it ask to import select first radio button which is import setting from previous config
there you go fixed
I am using Windows 7 Professional and I was having same problem #Bayu Mohammad Lufty not worked for me.
I simply delete .AndroidStudio1.2 from my C:\Users\UserName\ and restart my Android studio again.
It open Android Studio perfectly!
It configured everything again in next start :)
I'm a MacOS user.
I solved it by uninstalling Android Studio and reinstalling it again.
If you want to try this link helped me a lot.
Uninstall Android Studio MacOS (terminal)
When you are installing Android Studio, under Install type do not use standard setting, use custom setting instead, and check all the option boxes in the next step.
i have solve my same problem
i update my android studio, and i choose not to import my setting from my previous version than that problem appear.
than i realize that i have 2 AndroidStudio folder on my windows account (.AndroidStudio and .AndroidStudio1.2) and on my new .AndroidStudio1.2 folder there are no other.xml file.
than i copy other.xml file from C:\Users\my windows account name.AndroidStudio\config\options to C:\Users\my windows account name.AndroidStudio1.2\config\options
and that how i solve my problem.
I'm using UBUNTU and I got this same error. I restarted the set up using sudo and did a custom install. This solved my problem!
--More Specific--
re-installed using # sudo ./studio.sh
then I made sure to click "Custom Install"
then I made sure all packages were selected.
And I got this message Android virtual device Nexus_5_API_22_x86 was successfully created
I just run:
C:\Users[Username]\AppData\Local\Android\sdk\SDK Manager.exe
Install SDK Platform Android M Preview
And run Android Studio again.
It's working for me :D
When this error occured I first clicked retry for few times and waited for 2 minutes and clicked 'retry' then it installed without any error.(for 2 minutes I was searching to solve this problem online).
I was getting an "out of space" error, which left me scratching my head as I had plenty of disk space, until I realized that it ran out of space on /tmp, which on Arch Linux is mounted on a tmpfs with a size limit.
I'm just getting started with Android development and was setting up Android Studio on my mac. (Following the instructions here)
When trying to run a simple hello world application and trying to learn my way around the IDE, I noticed the "Android Device monitor" disabled. Any ideas how I can fix this? This should be important when debugging apps hence the question.
I'm not sure what other info might be important for this question. I did make a few changes in the SDK manager, but they were just installing more components on top of what was already installed.
Once you open a valid project, the buttons become enabled.
Note that, even if the option is disabled, you can still bring up the Device Monitor by running the monitor.bat file in the tools directory of the Android SDK. (On Windows you can just double click the file or run it from a cmd shell.)
This problem occurs to me today. And I just click the button on the pic.
Problem solved.
and If this didn't work ,you can check this list in your Android Studio
1.Tools->Android->Enable ADB Integration
2.If you open DDMS, CLOSE it .
If these didn't work too, check the official file.
