    This issue is happening to me on 2018.3.0f2 for devices running Android 7.0. So it hasn't been closed/fixed. Please look into it again. Using NET 4.6 and Stripping is disabled.

    I was told that this is a duplicate of: but I've never changed the Stripping option and I apparently have always had it disabled. Are there two bugs at play here?

    Happens for me in 2017.1.0f3 when building an empty project, even after setting Stripping Level back to Disabled. I have to restart Unity for stripping to actually be disabled. I'm not sure how incremental building works, but I deleted the target directory and built a new APK, and it still crashed on startup.
