Error: Invalid key or package name

Question

Hi, I keep getting the "Invalid key or package name even after verifying several times that the key is correct and that the package name is exactly the same that I used for the licence on the easyar page.

I have also re-create and delete keys in order to make my app work but it just keeps giving me the same error.

The app works when I turn the network connection off, but my app NEEDS to have internet connection, so it's not a solution.

What i've been doing is building the app on Unity, then exporting it to gradle and then attaching it to my Android app as a library, but I don't know if I have to enter the key in some place after building it from unity, because in unity I've already entered the key.

In the docs (https://www.easyar.com/doc/EasyAR%20SDK/Getting%20Started/2.0/Setting-up-EasyAR-Android-SDK.html) I see that when you are working on android studio, you need to enter the following method: 

protected void onCreate() {
    Engine.initialize(this, key);
}

but I don't know if in my case I have to do it too and where to put it.

Thanks.

Answer 1

I managed to solve this.

What was happening, was that the BundleId / PackageName have to match the AndroidApp BundleId / PackageName, and not the UnityExport ones.

So I just put the Unity project a different BundleId and then I updated my AndroidApp bundleId to match the EasyAR platform one and it worked!

My AndroidApp is made with Ionic, if someone wans to integrate EasyAR with Ionic, take a look at this plugin:

Everything works for EasyAR too, but you have to take a look at this here:

Hello,

You need to check if the name of the Sample you imported in Android Studio is the same as the Package name in the EasyAR official website.

Thank you!

When I export the project from unity to Android Studio, it just creates a folder with the name of the app that I'm creating, I just checked the package name in the AndroidManifest.xml file and is exactly the same as the one on the EasyAR page.
What I understand of your comment is that the folder (exported from unity) should have the same name as the package name (in EasyAR page).
I just did that and it keeps giving me the same error.
This only happens when I export that from unity to Android Studio, because when I build the .apk from Unity it works perfectly, but I don't need the .apk from unity.
Can you please help me or be more specific?
Thanks.
