Supporting Android platform?

[tiann]

I run the demo code in Android plaform:

fn main() {
    let me = procfs::process::Process::myself().unwrap();
    println!("PID: {}", me.pid);
}

and the error occurs:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: PermissionDenied(Some("/proc/sys/kernel/osrelease"))', /Users/weishu/.cargo/registry/src/mirrors.sjtug.sjtu.edu.cn-7a04d2510079875b/procfs-0.10.1/src/lib.rs:303:34
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Normal app in Android have no permission to read /proc/sys/kernel/osrelease, (it is forbidden by SELinux), how can i fix this?

Hi, thanks for the report.

This is unfortunately a bug: #138

I'm a little surprised to see this panic while calling Process::myself() (so seeing the full stack trace would be helpful), but this is a procfs bug that still must be fixed

It seems that backtrace is not working well on Android ?
