[bug] Cannot build for android

[Berrysoft]

Describe the bug

When packaging for android, tauri-cli tries to build for armv7. Actually I don't need that target, but don't know how to turn it off neither. It finds the right linker in the Android NDK - armv7a-linux-androideabi24-clang.cmd, but adds param -march=armv7-a behind it. Cargo calls CMD to execute the link command, and CMD refuse a param like "-march=armv7-a". It just throws a line of error

=armv7-a"" was unexpected at this time.

The param -march=armv7-a comes from the armv7-linux-androideabi target of rustc.

https://github.com/rust-lang/rust/blob/master/compiler/rustc_target/src/spec/armv7_linux_androideabi.rs#L13

I don't know why it calls CMD, and don't know why it adds such a param, and even don't know how to remove it.

Reproduction

cargo tauri android build

If you feel it is complicated, start a cmd. Suppose your linker is %FOO%\armv7a-linux-androideabi24-clang.cmd, type

"%FOO%\\armv7a-linux-androideabi24-clang.cmd" "-march=armv7-a"

You will find that it works if you remove the quotes.

"%FOO%\\armv7a-linux-androideabi24-clang.cmd" -march=armv7-a

Expected behavior

Build successfully.

Or give us an option to disable armv7 target.

I modified the generated project and removed armv7 arch. It is resolved temporarily.

I wasn't able to reproduce this at all with a new project, try recreating the project from scratch.

[Berrysoft]

I've installed a new NDK and could still reproduce that. However I've found it an NDK issue. I've opened one for NDK: https://github.com/android/ndk/issues/1856

We're seeing this issue on CI: https://github.com/tauri-apps/tauri/actions/runs/4774744796/jobs/8488622948?pr=6708#step:13:783

@Berrysoft may I ask how you managed to remove the armv7 arch? I have the same problem and I'm new to android dev.

[lazytiger]

add "targetList=aarch64,x86_64" in gradle.properties

I choose to modify NDK following this comment: https://github.com/android/ndk/issues/1856#issuecomment-1542248775
