Do you want us to reinstall the Android Emulator? I've tried to go Tools > Device Manager > New Device.Īndroid emulator component is incomplete therefore the device Pixel 3 XL Q 10.0 - API 29 could not be created. This is on a new blank Xamarin Forms project Using an x86 system image can speed up the emulator considerably. The First Prototype is an emerging Mobile App Design and Development consulting small business, specializing in Cross platform and Native iOS & Android apps. I've got Visual Studio 2019 on MacOS Catalina Only start and restart your app from Android Studio, and not from the target device. What are the steps I need to take to get this working? When we enable these options we can finally obtain startup performances very similar to a native app (similar, not the same…yet!) so may suggestion here is to enable AOT and Startup Tracing and to create a Custom Profile for every project you are going to create! My suggestion is add this page as preferite as you will need it for every project you are going to create.Hi i'm really struggling to get the Android emulator running on my Mac.
I’ve personally tried the Startup Tracing with Custom Profiles and trust me, the results are impressive, the first time i couldn’t believe my eyes. This will solve the problem and you will be able to have your custom profile.Īgain according to Xamarin (you can read it here) this is the result of their tests: csproj file) write: set PATH=%PATH% "C:\Program Files (x86)\Android\android-sdk\platform-tools" If you do, open the Command prompt with admin privileges and (always in the folder containing you Android. ONLY IN CASE OF ERROR: When running the command msbuild /t:FinishAotProfiling some people (I had it as well on one of my machines) get the error:Īotprofile-tool: Unable to read profile through local port: 9999 Generate a Custom Profileįollow this short guide and you’ll get your Custom Profile in no time and you’ll really improve the performances of your Xamarin Forms apps for Android. I’ll try to keep it as easy as I can and as usual, if you have questions or issues, leave a comment here and I’ll reply as soon as possible.

Unfortunately for now there is no UI to generate a Custom Profile (hopefully Microsoft will do it soon), but I’ll show you how to generate your Custom Profile in no time.

The code for SwiftUI is not relevant as it was all working perfectly fine before. We can now generate a Custom Profile of our app! If we do that, the next time our app will run in no time (Cool cool cool cool cool…cit.). Output of iOS Launch Screen App in Swift. I was really impressed by it so do a favour to yourself and continue to read!

Since Visual Studio 16.5 (or Visual Studio for Mac 8.5), Xamarin did even better and trust me, the result is more than amazing.
#App not showing up on android emulator xamarin for mac apk#
It means that AOT is amazing and you should enable it but if you care about the apk size you should definitely enable the Startup tracing as well, so you’ll get an incredible startup speed improvement without affecting too much your apk size.

If you enable this option, the profiler will do its magic (memory, execution time and some stats) to create a profile for your app to increase the performances without affecting too much your apk size.Īccording to Xamarin (you can read the full post here), these are the results of enabling these options: Type Since Visual Studio 2019 Version 16.2 you were able to enable the Startup Tracing. At this point you can decide what is more important for you, performances or apk size. If you enable the AOT Compilation (Ahead of time), your app performances will improve significantly and so the startup time, but your apk size will increase as well. If you go into the Android Options of your Xamarin projects, you’ll see this:
I’m not going into many details here as the only thing that matters is how we can improve the performances of our Xamarin Forms apps for Android. A native app takes nothing while even the most basic Xamarin forms apps takes several seconds to show up on Android.ĭuring the years Xamarin has tried hard to make things better, sometimes with very small improvements and other times with a bit better improvements but now with the new Visual Studio release (> 16.5) they did something amazing, something called Startup Tracing with custom Profiles. Since ever, one of the most annoying problems of Xamarin Forms on Android was the start up time. It then gives Chrome the ability to run Android apps and games (albeit with limited support).
