    When I try to create instance of UnityPlayer in native android, passing context that is not activity:

    mUnityPlayer = new UnityPlayer(getContext());

    e.g. application context, my app crash with following stack trace:

    2021-05-27 15:40:09.776 2276-2328/com.DefaultCompany.LW2WithOlderUnityVersion A/zygote64: java_vm_ext.cc:534] JNI DETECTED ERROR IN APPLICATION: can't call android.view.WindowManager android.app.Activity.getWindowManager() on null object

    Question is what am I doing wrong?
    Can UnityPlayer be created with context that is not activity?
    Thanks!

    We've stopped supporting this due to very low interest in it.

    Hi, do you mean UnityPlayer cannot be created with non Activity (such as Service) context anymore? Do you know any method to support it or which unity version support this? :(

    In Unity 2022.1 UnityPlayer constructor has an Activity parameter. Unity 2020LTS and 2021.2 still has a Context parameter, however UnityPlayer code assumes it received an Activity. If you are using a Unity version which works with other types of contexts, then that most likely is a lucky accident, since on our side only an Activity Context is tested.
    I'm curious, which Unity version are you using currently?

    :(:(:(
    I am learning to make live wallpaper for Android using the Android WallpaperService and Unity 2021. I googled the tutorials and tried, then the same error in this post happened.
    Someone says Unity2018 can work well. So why the latest Unity version stops supporting non-activity context? Is there any solution to make live wallpaper with latest Unity? It confuses me a long time. Please help me

    Hi, I currently am selling an asset based on this feature. Does this mean I must retire the asset?

    I think the answer is yes. Is your asset for making wallpaper？

    Yes, it does. I think unfortunately you're probably correct.

    Can you give a definitive response to whether or not this is true?
