Stephen,

Have you tried using Nexus/Pixel device? This should work with those devices. Please let us know.

I don't own those devices, but I am really looking to reach the larger Android N family of devices in general

Hi Stephen, do you mind sharing your apk with us? We'd like to reproduce this and solve your problem.

Hi,

I just followed the steps again, creating a new project with both Instant App and C++ support, and the resulting project published as both a regular App (shows 'Hello from C++') and an Instant App (shows 'Open App' and 'Open in Browser' options).

So this issue appears to be fixed in Android Studio 3.0 Beta 6 / Build Tools 26.0.1... I still need to test my actual app that utilizes C++, but if I run into any other issues I can report them separately.

Thanks!
- Stephen

Just an update - this bug still persists in Android Studio 3.0 beta6.

The above comment true, but the crash happens when you click 'Open App'

I am facing exact same issue. My instant app uses native libs one of them loads at onCreate. And on ASUS ZB602KL (Android 9) all goes fine. But on Samsung s6 edge (Android 7) and other less Android O devices crush happen because System.loadLibrary() try to finds so file in strange place:
dlopen failed: library "/data/user/0/com.google.android.instantapps.supervisor/files/native-lib/ru.arproduction.mmrs/110/libEasyAR.so" not found
I was trying to adb list that directory /data/user/0 but there is no such place on devices or permission denied.
On Samsung s6 edge (Android 7) I have Google Play services for Instant Apps (Version 6.08-release-335882674)
