1 month ago @jianshu93 I've created an android branch, can you try to compile it and run tests?
minimap2-sys compiles just fine, but the main crate is complaining about missing libz.so, but I believe it is in the NDK (I'm just using cross to compile).
Let me know how you get on.

1 month ago Hi @jguhlin,
I just tested, it was successful. Maybe we need some code cleaning for the new Rust v1.82? I attached the building and test:

Thanks so much! let me know how I can use it when adding to crate.io (e.g., a feature?)

1 month ago Hi @jguhlin,
Check this for compiling with easy: https://github.com/BrainiumLLC/cargo-mobile
I still manually setup android studio toolchain path but this may be more convenient.
Thanks,

1 month ago @jianshu93 For now use the branch. Later it won't need a feature (probably). I don't want to merge this until I can get the tests to run using cross.

1 month ago Hi @jguhlin,
I forget to mention, you also need to configure the cargo configure file under ~/.cargo/config.toml:
[target.aarch64-linux-android] linker = "/Users/jianshuzhao/Library/Android/sdk/ndk/27.0.12077973/toolchains/llvm/prebuilt/darwin-x86_64/bin/aarch64-linux-android35-clang" ar = "/Users/jianshuzhao/Library/Android/sdk/ndk/27.0.12077973/toolchains/llvm/prebuilt/darwin-x86_64/bin/llvm-ar"
Tell the linker to use android studio provided clang. Not sure how this can be integrated.

I've opened up a discussion on cross here: https://github.com/cross-rs/cross/discussions/1537
For not being able to run the binary, is it the same architecture? aarch64 and the machine you are running on? That's probably the error you are receiving. You could run qemu-aarch64 to emulate aarch64.
I'm using these commands to test:
cross test --target aarch64-unknown-linux-musl
cross test --target x86_64-unknown-linux-musl
cross test --target aarch64-linux-android
cross test --target x86_64-linux-android
cross test --target armv7-linux-androideabiThe first two work, the rest do not. Hopefully someone will have some insight and we can merge into the main branch
It looks like cross does come with the NDK, so it should compile and run, but is having an issue finding the correct zlib.

3 weeks ago @jianshu93 Haven't had any luck figuring out a workaround with cross, but I've merged this branch into main for now. If it does work when you deploy it let me know and I'll make a note of it.
Hi @jguhlin,
I am not sure whether this is interesting to others but I want to report here. I was trying to import and compile many Rust software packages to Linux-based android device so that we can run them on phones for a mobile bioinformatic era (CPU for phones are now quite powerful, like SnapDragon 3 generation). For pure Rust based packages, I have no problems for example, my GSearch crate, sourmash crate, rust-mDBG crate and many others. However, when I was trying to compiling minimap2-rs, there are tons of problems:
install android studio first and deploy it for rust in .bash_profile like this:

I can see that android clang does not support -lpthread, which is only for linux. However the android libc (bionic) does support many pthread functions: In Android, all pthread functionality is directly available through the Bionic libc without requiring explicit linking. This means that while you can use pthread functions like pthread_create or pthread_mutex_init, you don't add -lpthread to your linker flags.
I am wondering whther it is possible to add a conditional compiling for android devices so that -phthread is not used but it is actually functioning.
I also want to hear how @lh3 thinks, https://github.com/jguhlin/minimap2-rs/issues/63#issuecomment-2269003167_
