Android studio 3.5 requires Refresh Linked C++ project each time I build the app

Issue

Since I updated to Android Studio 3.5 when ever I run the application (no matter which button I pick) first thing that happens is this error:

Build command failed.
Error while executing process Library/Android/sdk/cmake/3.6.4111459/bin/cmake with arguments {--build /.cxx/cmake/prodDebug/arm64-v8a --target jni-lib}

Only after I "Refresh linked C++ projects" / "Clean project", the application will then compile, build and install on the device.

This started happening only after upgrading AS to 3.5.

Any clues why? Thank you!

Solution

So eventually I gathered that building for arm64-v8a during debug has stopped functioning correctly for some reason in AS 3.5.

So as a fix for release builds, I simply use

ndk {
    abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64
}

and

ndk {
        abiFilters 'armeabi-v7a', 'x86', 'x86_64
    }

for debug builds heh.

Perhaps, some day, I'll look into the exact reason why 'arm64-v8a' fails. Anyway, this solved the problem for me :)
