I have been trying to find some reliable solution to this but I couldn't. I have added Android 11 - S which is an Android 12 Beta image in Android SDKs as shown in the following screenshot
But when I go and try to create the Emulator device in Device Manager I don't see this API in the list
What Am I doing wrong here?
Final release planned for early 2022.
In Visual Studio you can find Android 12 here:
From document Android 12 Preview, we find that :
The Android 12 Preview program runs from February 2021 until the final
public release to AOSP and OEMs, planned for later in the year. At key
development milestones, we'll deliver updates for your development and
testing environments. Each includes SDK tools, system images,
emulators, API reference, and API diffs.
Since it's still in beta, there's definitely some instability, so for that reason, it's still not released. We need to wait patiently for the final release.
In VS2022 17.0.5, Android 12 is available as a choice in the emulators list. However, be warned. Debugging/deploying android Xamarin in VS 2022 as of this version is sloowwwwww. Anyone with any leads on that, please hit me up!

I am trying to build an Android app to make a simple prototype. Using Microsoft Visual Studio 2022 (v17.2.4), I create an Android App (Xamarin), blank app. And I target Android 9.0 version.
But, I have compilation errors :
Could not find 2 Android X assemblies, make sure to install the following NuGet packages:
Xamarin.AndroidX.Lifecycle.LiveData
Xamarin.AndroidX.Browser
Problem is that I can't install these NuGet packages because they need Android 12.0 version or greater :
Package Xamarin.AndroidX.Lifecycle.LiveData 2.5.1 is not compatible with monoandroid90 (MonoAndroid,Version=v9.0). Package Xamarin.AndroidX.Lifecycle.LiveData 2.5.1 supports:
monoandroid12.0 (MonoAndroid,Version=v12.0)
net6.0-android31.0 (.NETCoreApp,Version=v6.0)
So I don't know how to solve this. I don't want to target Android 12 version, I need this app to launch on an Android 9.0 device.
What are these libraries the app need to compile? Can I do without them? I don't find any references to them.
Note : I have a warning too on the same way, but not sure if it has to deal with my compilation issue. I Put it anyway, if it can help :
Warning Google Play requires that new applications and updates must use a TargetFrameworkVersion of v11.0 (API level 30) or above. You are currently targeting v9.0 (API level 28).
Please, any idea to solve my issue?
I just want to compile and launch an Android (Xamarin) blank app targeting Android 9.0.
Thank you and have a good day,
I'm finding this a problem too. Just deployed an app (Dec 2022) that targeted 28 / 12 and has min version 10 as appears enforced by Google?
Prob is I've got a lot of people wanting to use the app that can't see it because they have ancient phones (9 or earlier - is that 5 years or more). Seems a bit tough? Is there a way to overcome this.
I assume that the today's Xamarin Android project templates are designed to compile with Android 12. I don't think there is a way to build them with Android 9.
I guess we just have to find another older template?
For my part I had finally took an older project I had instead of creating a new project.
I can only select up to Android 7.1.1:
What gives, Google?
And with Android 7.1.1 you don't seem to be able to sign into Google services, which also limits functionality:
Android Studio 4.1.1 released in November 2020 includes an AVD with Android 11 that can run ARM-only apps. The release notes explain that this new virtual device can convert AMD instructions (32 bits) into x86 code on the fly, without major loss of performance. Because of that, we may expect future Android Studio emulators to also run ARM apps in a similar way.
AVD running Android 10, 9, 8, as far as I can see, still only support x86 though, and I suspect that will not change, because that would require Google to retroactively apply this new technology to older virtual devices, and I don't think they're ever going to do that.
I have been using the Visual Studio Emulator for Android to test my Xamarin apps and I am very impressed with the performance of Hyper-V over HAXM. However I can't seem to find any options for emulating anything past 6.0 API Level 23:
Is there any way to download additional system images for API levels greater than 23?
According to this and corroborated here, there will be no support for levels above 23 and they recommend that use the improved emulator that comes with the Android SDK. Here's the quote:
From Microsoft:
Hello,
This is an automated message. Unfortunately, we have no plans to
publish Android images past 4.4. We recommend that you try Google or
GenyMotion’s emulator for future images of the Android operating
system.
When we first released the Visual Studio Android emulator, the Google
emulator was slow, out-of-date, and a significant source of pain for
mobile developers. In addition to the great work performed by
GenyMotion, the Visual Studio Android Emulator proved that emulators
can be fast, productive tools for mobile development.
Since then, Google has responded to developer feedback by increasing
their investment in their tools. The next generation Google Android
Emulator has closed the feature gap that previously differentiated
Visual Studio’s emulator. Google’s emulator has become much faster and
more feature rich.
We also know that, for mobile developers, authenticity is key. We
believe that Google, as the platform owner, is best positioned to
provide ongoing support for new versions of the platform in a way that
accurately and authentically reflects the real-world behavior on
devices.
For developers like you who’ve come to love and depend on the VS
Android Emulator, thank you! We will continue to support in-market
platform images according to Visual Studio’s generous support policy.
However, Microsoft will no longer produce new Android images for the
VS Android Emulator. We consider this a successful project that has
come to a natural conclusion.
Happy coding!
I have installed Android API version 21 (lollipop), since i have been trying to set up an AVD . There is no "new" button,instead there is a "Create" option . then no matter what configuration i set , AVD manager fails to create the emulator.I have checked for updates.No issue with OK button . I tried a lot of things ... Any clue ??
Android 5.0 Lollipop has not been released by far. But it will be at 12th Nov at America time zone. So, the IDE downloaded from Android Developer site is the preview version. And, I tried it as you, but, I realized it was incomplete. And some features were unavailable. So, I have been waiting for the release version, Android 5.0 Lollipop and its IDE bundled with ADT and Eclipse. Hopefully, this will help.
I am very new to the android development. I currently installed Android 4.0.3(API 15) via android sdk manager. I am in great confusion if this version is enough to develop the android apps or we should install from Android 1.5 (API 3) to the latest. Thanks in advance.
Depends which versions you want to support.
This depends on your users and features you use.
(Also, I hate the emulator, so depends on what device you actually have access to!)
If you're only playing around and figuring things out don't worry about it and just use the most recent.
To get a sense of what each version has changed, take a look at the platform highlights:
4.0
3.2
3.1
3.0
2.3.4
2.3.3
2.2
2.1
With regards to learning, 4 is much better than 3, since 4 is open source, so you can look at the source. In fact if you're using Eclipse, you can browse the source within your project!
