Hello again,

The minimum Android API level Vuforia supports is defined here https://library.vuforia.com/articles/Solution/Vuforia-Supported-Versions

I confirmed that this is accurate and was able to successfully build the Core Samples project in Unity 2017.2.0f3 with Vuforia 6.5 to a Galaxy S3 running Android 4.1.1. I had the Minimum API Level set to 4.1 with the Target API Level set to "Automatic (highest installed)."

Can you confirm that your minimum and target API levels are set correctly and try deploying again?

Thanks,

Hello,

Thanks for the reply, 

I`m a unity developer and i know where to set.

Actually your SDK for AR is supported for minimum API level 24 means the target Android OS is 7.0 and + but my target is 6.0 or less. 

Now my question is, when i set the target to 23 or less, while building It is showing error of target SDK version &  asking to set minimum 24.

So, How can i build an apk to run in Android 6.0 or less also. 

Hello avinash018,

You can specify the minimum and target versions of Android OS in Player Settings -> Other Settings -> Identification.

Thanks,
