Hi, I've a problem when building my Android Project, it says that my API version isn't API 30 so I cannot launch the build.
The error message :
Erreur : The android.jar file could not be found for API level 30. This means that the Android SDK platform for API level 30 is not installed. Install it in the Android SDK Manager (Tools> Android> Android SDK Manager ...), or change the Xamarin.Android project to target an installed API version. (C: \ Program Files (x86) \ Android \ android-sdk \ platforms \ android-30 \ android.jar missing.)
The thing is that this API 30 doesn't exists in Android SDK Manager :

Hi AurelienBouillon,
You need to change the framework of your project to API 29:

Hi, it shows this :
C:\Program Files (x86)\Android\android-sdk\emulator\emulator.EXE -no-boot-anim -avd pixel_2_q_10_0_-_api_29 -prop monodroid.avdname=pixel_2_q_10_0_-_api_29
Unable to start the pixel_2_q_10_0-_api_29 emulator.
Hi @Aurélien Bouillon , please refer to this thread: Xamarin: Android phone emulation not working, to check if your hyper-V has been opened in your machine.
Hi, I cannot open Hyper-V on my pc because I'm on Windows 10 Family
Hi @Aurélien Bouillon , the android emulator needs to enable and run Hype-V. Please refer to this document: System requirements . You need to install Windows 10 Enterprise, Pro, or Education on your machine.
It's like.. 150$ ?? Is there any other way to do this ?
Hi @Aurélien Bouillon , maybe you could try to follow this answer to enable Hype-V in windows 10 home.
I think you can try to download it (should be a tool inside Visual Studio to download SDKs).
Otherwise change the target platform to 29 (android 10)
I've tried but it doesn't work, it shows the same message about API 30

It also shows "Xamarin.Forms recommends TargetPlatformMinVersion >= 10.0.14393.0 (current project is -1) and Xamarin.Forms recommends TargetPlatformVersion >= 10.0.17763.0 (current project is -1)
