why next button is disabled in xamarin studio? - xamarin

I installed the xamarin studio and next button is disabled when I want to create a new project.
What should I do?
next button is disabled:-

To hit the 'next' button you will have to have an Android SDK installed so you can check the box next to the Android Target Platform.
I believe Xamarin Studio installs with the Android SDK Manager installed, try searching for it on your computer (SDK Manager). Once you install at least 1 SDK in the manager you should be able to hit next.

Visual Studio 2017 your emulator is out of date please update by launching android studio

In Visual Studio 2017 (new installation) when I'm running the android emulator "VisualStudio_android-23_x86_phone" I'm getting the message "Your emulator is out of date please update by launching android studio".
This message doesn't prevent me from running the application and only appears once every day (when I run VS for the first time)
So, how can I resolve this problem?
Thanks
open your Android SDK Manager icon on Visual Studio toolbar. Check the Android SDK Tools and SDK Build Tools on Tools folder and then click Install Packages. But, I recommended you to use Genymotion Emulator

Can't create a project with Xamarin on Visual Studio

I'm having a problem with running the ios .cspoj file, when i want to start new project for iOS devices I get error that i have to install Xamarin. I have installed Xamarin program and still says that i need to install Xamarin for start ios project. I don't know what to do so i hope you guys can help me fix the problem.
Here is image of the problem
You said that you installed the "Xamarin program", but what exactly did you install? I cannot tell from your screenshot if you are using Visual Studio 2013 or Visual Studio 2015, but...
If you are using Visual Studio 2013, you will need to use the Xamarin Universal Installer(Just input your information and the file will be available to download).
If you are using Visual Studio 2015, then you can install Xamarin directly from within the Visual Studio 2015 installer window. Using Microsoft's guide from here you can:
...open Control Panel > Programs and Features, choose the Visual Studio 2015 item, and click Change. When the installer opens, click Modify
Check the following boxes:
Cross-Platform Mobile Development > C#/.NET (Xamarin)
For Windows 8+: Cross-Platform Mobile Development > Microsoft Visual Studio Emulator for Android
(Optional) If you plan on targeting Windows devices, also check Windows and Web Development > Universal Windows App Development Tools and/or Windows 8.1 and Windows Phone 8.0/8.1 Tools
Click the Install button
Once installation is complete... check for Xamarin updates through Tools > Options > Xamarin or Tools > Options > Xamarin > Other, where you’ll find a Check Now

Xamarin error on visual studio

I install xamarin on my visual studio and when i want to create a blank app project it gives error :Object refrence not set to an instance of an object.
this is out put:
enter image description here
Looks like you didn't install the (right) Android SDKs.
Go into Tools > Options and find the 'Xamarin' page. Then go into 'Android Settings' and check if the SDK path is found.
If these aren't filled correctly you should install them. Easiest is to download the installer from Xamarin or reinstall from Visual Studio (through add/remove applications and edit Visual Studio installation).
You can install and manage seperate SDKs by using the Android SDK manager. You can find this under Tools > Android > Android SDK manager.
In the next screen you can install the SDKs you want to use with the according emulator images, etc.

error in running a app in visual studio

firstly I installed visual studio 2015 community. at the end of the installation the android sdk, ios and xamarin studio didn't downloaded correctly Message appeared.
then i was having an offline setup of xamarin studio only so i installed that successfully.
after that i created a new project by FILE->new project-> visual c# -> android ->blank app on visual studio.
now when i RUN it, there are many errors like :
Xamarin.Android for Visual Studio requires Android SDK. Please set Android SDK path on Tools->Options->Xamarin->Android Settings menu.
Since i installed only XAMARIN studio not android sdk, so can i install android sdk again externally just like i installed xamarin studio and if YES then How?
Try Update All the SDK because your project may required higher SDK to build
In Xamarin Studio, Open Tools--->Open Android SDK Manager----->Then install what is missing

Xamarin Studio cannot find Android tools/devices

After installing Xamarin Studio, I've found it to miss Android related items such as Android SDK Manager under Tools menu:
Additionally I cannot run the application on an actual device, nor see any emulator:
Please note that I've developed Android app using Eclipse prior to this so I have everything properly setup (including device driver, ADB, Android SDK/NDK, etc), and have also made Xamarin Studio work on another computer. The problem is that it refuses to work on this particular computer, and uninstall/install it didn't help.
How do I fix it so that Android tools are shown in Tools menu and I can run Xamarin applications on an emulator/actual device?
The following steps resolved the issue for me:
Uninstall Xamarin Studio
Uninstall x86 JRE/JDK 1.6 installed by Xamarin Installer
Run Xamarin Installer and let it reinstall both JRE/JDK & Xamarin Studio
Don't know why the Xamarin installation wasn't working correctly the first time, nor why the above steps work, but it worked.
