Error when compiling program

Hello. I have an error when compiling program.

D:\AR3DObjectsAndShadows\Temp\StagingArea\AndroidManifest-main.xml:3:3-72 Error:
uses-sdk:minSdkVersion 14 cannot be smaller than version 16 declared in library D:\AR3DObjectsAndShadows\Temp\StagingArea\android-libraries\gvr\AndroidManifest.xml as the library might be using APIs not available in 14
Suggestion: use a compatible library with a minSdk of at most 14,
or increase this project's minSdk version to at least 16,
or use tools: overrideLibrary="com.google.vr.cardboard" to force usage (may lead to runtime failures)
UnityEditor.HostView:OnGUI()

Please help me correct this error?

 

Well, as the error itself suggests, I recommend you "increase this project's minSdk version to at least 16." Personally, I tend to use 25. You find this in the Player Settings under "Other Settings":

 

JoeStrout, I changed the Minimum API Level to 25, but I have the same error when compiling. Please help, how to correct?

 

Hmm, that's weird. I suspect your project has a AndroidManifest-main.xml file that's overriding the values from Unity, or something along those lines. Did you create this project from scratch, or is it something you downloaded from somewhere?

 

Did you isntall the SDKS that are needed for lower API levels? When starting Android Studio, go to configure/SDK manager, and check everything above level 21 for example and you'll bee good to go. If you did that already, you can try reinstalling Android Studio, or you can try setting the SDK path in Unity.
