Android SDK could not be found - Android SDK Location is correct

Question

I've installed Xamarin and tried in Visual Studio to start with a small app and test the web view with this. So for this, I've installed the JDK, the Android SDK and Android NDK on my computer. I'm working throught a tutorial for a web view and I have the problem, when I run the Main.axml, it shows me the error, that my Android SDK could not be found (look at the first attachement). When I check my location paths for the JDK, SDK and NDK, it shows me the correct path and a green tick, so the path and files are correct (look at the second attachement). But my app don't recognize it. What's the problem here? I found some threads on stackoverflow for the same problem, but nothing helped me.

1. Attachement

2. Attachement

• OS: Windows 8.1
• IDE: MS Visual Studio 14.0.23
• Xamarin: 4.2.0

EDIT:

I also tried to open my Android SDK Manager, but this one is disabled in my visual studio. I've installed Xamarin, so it should work:

Any ideas? Thanks.

Answer 1

I tried so many things and finally I have the solution for my problem:

Possible reason for the problem: I just installed the Xamarin, which installes also the JDK, Android SKD and Android NDK in it's wizzard, so I thought this should be the correct versions. After installing Xamarin, I opened my Visual Studio and checked the paths (Tool - Options - Xamarin - Android seetings) for my JDK, SDK and NDK. The paths show on the versions, which were installed by Xamarin. My Android SDK Manager was disabled.

Solution: Then I uninstall everything - the JDK, SDK and NDK and also the whole Xamarin and my old Android Studio. After that, I decided to install the newest JDK from the Java website, the newes Android SDK/NDK from the Android Studio website and a plane xamarin without the sdk/jdk installation. So I could be sure, that I have the correct versions. After the installation, I again opened Visual Studio - Tool - Options - Android seetings and set the paths to the new versions. Than I checked my Android SDK Manager and it was finally enabled and so I installed also the newest Android SDK Tools. After that I cleaned and builded my solution, start it and my android emulator opens my webview page. So I think, the best way is to install the required programms from their website and not automaticlly with xamarin. Now it works. Cheers.
