    So I'm finding that if I build an app bundle using Gradle then a load of stuff that works fine in individual apks gets broken. For example Vuforia AR stops detecting AR core being available.

    I can build an apk using the internal build system and all checks out fine, ARM64 or ARMv7 or joint doesn't matter.
    I can export a Gradle project and build an apk and that works too.

    However in order to publish I'm building signed app bundles and as soon as I do and install via the app store then things stop working, anything that needs a 3rd party library seems to stop functioning.

    Is there some trick to building a Gradle project generated from Unity to an app bundle to stop this happening?

    Unfortunately building a bundle directly from Unity fails to work so I haven't been able to test that option.
    Everything I tried to fix that has failed.

    Did you check the logcat for errors?

    Also, what kind of errors you see when exporting app bundle from Unity?

    I'm not seeing any errors in the Pre-launch tests. Just 1 warning about APIs

    API     Ljava/lang/invoke/MethodHandles$Lookup;-><init>(Ljava/lang/Class;I)V

    The error I get building from Unity directly is:

    ...The sticking out tongue emoji's are now just taunting me :(

    Google says, that's something is locking your cache, search for fileHashes.lock in <userprofile>\.gradle\caches\

    Try deleting it

    Creates a new lock file when I build and then seems to give much the same results

    So giving up on bundles until this gets fixed, hopefully Google don't drop support for apks

    Unfortunately I'm using 2018.3.14 and these are different instructions to those you posted

    These are the ones I followed
    https://docs.unity3d.com/2018.3/Doc...667.1369058017.1570450803-62453373.1568817120


    2018.3.14 doesn't give me the option to install the Android SDK via the hub
