Unity requires Android SDK to be minimum API level 21

Question

So I've been trying to build a Unity 4.6.1 project in Android, but the problem is that my Android SDK is outdated. However, I believe Google discontinued support of the traditional ADT to switch to Android Studio. Android Studio doesn't have an easy to find SDK folder in version 1.0.1. This is the error I get: "Error building Player: UnityException: Minimum platform required is Android 5.0 (API level 21)" How do I build my Unity project for Android, if the ADT doesn't have support for API level 21?

Solution 1

Click on the SDK manager button (on the top) and in a grayed out text on top of the window (which looks like it did in ADT) it should show you the location of your SDK(e.g. C:\users\admin\appdata...) . And you can change that location in the settings. Just remember to move the files.

Solution 2

1) Download SDK Tools (v25.2.5) from http://dl-ssl.google.com/android/repository/tools_r25.2.5-windows.zip

2) Extract in a folder and navigate inside.

3) run android.bat which would open SDK Manager.exe. Update the packages from this tool (must done step). You can also install any specific API if required in your unity project.

4) In Unity, Go to Edit -> Preferences -> External tools and update path for JDK and the path of the folder where you extracted SDK Tools.

Now Unity would build for android without any issues.
