可以使用以下代码来获取当前设备是否支持ARcore：

private boolean checkARCoreSupport(Activity activity) {
    try {
        // First we need to check for the existence of the ARCore service
        PackageManager packageManager = activity.getPackageManager();
        packageManager.getPackageInfo("com.google.ar.core", PackageManager.GET_SERVICES);
        
        // Then we need to check if the device is compatible
        ArCoreApk.Availability availability = ArCoreApk.getInstance().checkAvailability(activity);
        return availability.isSupported();
    } catch (PackageManager.NameNotFoundException e) {
        // ARCore is not installed, return false
        return false;
    }
}

该方法使用PackageManager来检查设备上是否安装了ARCore服务，并使用ArCoreApk来检查设备是否兼容ARCore。如果返回值为true，则当前设备支持ARcore，否则不支持。
