    catch (Exception ex)
    {
        // If we get here only means the Package does not exist
    }

    return false;
}

Dear friend, it is impossible for that to happen because if a game searches as such another Android app detects it as a suspicious application,
and if you find something for unity you tell me that I’ve been looking for myself
