Weather Demo doesn't build for Android
hut opened this issue · comments
I tried building an apk with xbuild and slint 1.7.1 for the weather demo example, but it gives me this error:
~/.../examples/weather-demo$ x build --platform android --arch arm64
[1/3] Fetch precompiled artifacts
info: component 'rust-std' for target 'aarch64-linux-android' is up to date

Error: failed to locate bin /path/to/slint/target/x/debug/android/arm64/cargo/aarch64-linux-android/debug/librusty_weather.so
Turns out it created a librusty_weather_lib.so in that destination instead of a librusty_weather.so. I could resolve this by renaming librusty_weather_lib.so to librusty_weather.so. But this should not be happening, right? Perhaps there is something misconfigured in the Cargo.toml?
My system is ArchLinux with slint 1.7.1, rustc 1.80.0, xbuild 0.2.0, android-sdk 26.1.1-2, android-ndk r26.d-1, android-platform 32_r01-1.
I believe this was fixed recently. Could you try again from the master branch?
(edit: i believe this could have fixed it: #5715)
Oh, embarrassing, I should have seen that PR!
Unfortunately, same problem with a fresh build on master (b1dab29).
It creates a libweather_demo_lib.so but in the "Create apk" step it looks for a libweather_demo.so.
Full build log on master:

Perhaps this is some difference between cargo-apk and xbuild? Our CI uses the former to build an apk and that works. Maybe there’s a config key?
Right, xbuild has some issues when we rename things in Cargo.toml:
rust-mobile/xbuild#161
So maybe related.
(We need to rename the lib in our example because of support of both a binary and a lib. Although since there is a - in the name, this might not be necessary.)

Solved the problem for me, just weather_demo_lib to weather_demo in the Cargo.toml and the build doesn't fail.
