    [UE 4.19] Android Package/Launch fails

    Hello everyone,

    I've posted a similar question to answerhub ( https://answers.unrealengine.com/que...d-project.html ), but noone answered. What I describe below is for a game I'm making. However, I have the exact same behavior with default templates. Note that my project uses C++, it's not blueprint only.

    So I try to package my game for Android (ATC) and I get this long error:

    Code:

    • Running the editor as Administrator
    • Uninstalling my VS 2017 and installing VS 2015
    • Reinstalling CodeWorks a bunch of times
    • Upgrading Android SDK
    • Use independent Android SDK/NDK (not those of CodeWorks)
    • Upgrade Unreal Engine (the error started on 4.18 but continues on 4.19)
    • Try packaging Blueprint-only projects. Didn't work, same problem
    • Mess around with sdk/ndk versions on Project Settings
    My Project Settings:
    • SDK API Level - matchndk
    • NDK API Level - android-14
    • Minimum SDK Version - 14
    • Target SDK Version - 14

    I just don't know what else to try. Could someone help me please?

      Found it. Jesus christ.

      So, the problem has something to do with disabling plugins. After 3 days almost going mad, I noticed that the problem occurs ONLY when I disable OculusVR and SteamVR plugins. Funny enough, disabling them is the very first thing I do every time I start a new project.

      So the steps to reproduce would be:
      1. Create a new project for mobile (even empty project)
      2. Package to verify it packages correctly
      3. Disable ANY plugin.
      4. Restart the editor
      5. Package again
      Package fails.

      Jesus christ. I have no clue what's going on. Could someone help me understand if that's MY problem or a bug in Unreal? Should I submit a bug report?
