WearOS executorch `dlopen failed: library "libexecutorch.so" not found`

[Heinrich-XIAO]

🐛 Describe the bug

When I open my app, it immediately crashes.

This is all I had to add for it to break. I added it into app/build.gradle.kts. I'm running on a galaxy watch 6.

    implementation("org.pytorch:executorch-android:0.7.0")

Versions

0.7.0 of org.pytorch:executorch-android

@kirklandsign Can you take a loot at this ? I think Android Studio has a wear os simulator support , We can try and repro there ?

Thanks @Heinrich-XIAO for raising the issue

[cccclai]

Any chance you can try the 1.0 release?
