Invalid key build for android

Question

I have build project using easy ar 3 but it become invalid key , the key i create from easy ar 4 then i put in easy ar 3 project. So how can i fix this problem?

Answer 1

EasyAR Sense 3 and EasyAR Sense 4 use different license keys, you cannot use one key for both. And EasyAR Sense 3 is not available for new apps now so you need to use EasyAR Sense 4 with the new key or EasyAR Sense 3 with the old key.

P.S., when you get invalid key error, it does not always mean the key is not usable. The causes may differ in different cases.

Comments

what other cases make it as i have the same error in IOS and the key in developer and unity is the same and cant find the reason of the error

it works fine in android but get that error in IOS

Too many possibilities. Please check the logs and follow document setup guides.

SchemaHashNotMatched means the csapi.cs version and easyar.framework version not match, it will only happen if you are trying to merge multiple SDK releases and made something wrong. Try the raw packages first.
This should also fail on Android but we did not check.
