I created a blank Android App and I get the following error when I try to view designer for Main.axml.

[Something went wrong]

The installed Android SDK is too old. Version 25.1.3 or newer is required. Please update the latest version.

But I already have the latest version: Android SDK Tools 25.2.2

Please help me.

  • I'm having the same issue. Ridiculous, isn't it ? All I wanted to do was write my first Xamarin app, but I can't, due to this error. Yet (on the same laptop) Android Studio runs perfectly. I followed some StackOverflow tips to upgrade my Xamarin, and now it just demands an even higher version of the Android SDK ! I surrender.... I just wanted to write a dumb first Xamarin app, but can't even get that far. – Mike Gledhill Oct 18 '16 at 08:40
  • Hi..... i solved this by installing the sdk build-tools from 19.1 up to 25.2.2. I also installed the API 25, 24 and 23. Some links mention the API 23 as the solution. I have followed this link: https://forums.xamarin.com/discussion/47251/the-installed-android-sdk-is-too-old-version-24-3-or-newer-is-required... good luck – Turay Melo Oct 22 '16 at 05:27

Here is the process that worked for me:

  1. Install 64-bit JDK 1.8
  2. Update Android SDK Tools, Platform-tools, and Build-tools. Close SDK Manager and repeat if the version required in the warning isn’t shown. You may need to exit Visual Studio if you get "Warning! A folder failed to be moved"
  3. Make sure the Android settings in Visual Studio are pointing to the right locations: Tools > Options > Xamarin > Android Settings

This is the full post about what I did to resolve this issue.
