panics on termux

[phanirithvij]

When I try to run a very simple minimal reproducible example

use webbrowser;

fn main() {
    if webbrowser::open("http://github.com").is_ok() {
        println!("hello, github.com");
    }
}

With webbrowser = "0.8.1" as the only dependency

# can be run on termux (rust required, `pkg install rust`)
# cargo install sample_webbrowser --git https://github.com/phanirithvij/sample_webbrowser && RUST_BACKTRACE=full sample_webbrowser

The output is

thread 'main' panicked at 'android context was not initialized', /data/data/com.termux/files/home/.cargo/registry/src/github.com-1ecc6299db9ec823/ndk-context-0.1.1/src/lib.rs:72:30

Based on this stackoverflow answer, it seems that Android APIs are not available to programs running inside Termux.

In this scenario, it'd be best to detect the Termux environment and solve for it separately, as against treating it as regular Android env. I'll search online to see what mechanisms others have used to detect Termux env, but if you have any ideas, I'd appreciate the help greatly.

[amodm]

As of now, TERMUX_VERSION env var seems more appropriate, so I'll be proceeding with that as a way to detect the termux env in Android, unless you have better ideas.

@phanirithvij, please give the android-termux branch a shot. My local testing seems to show that this works, but I'll await your confirmation for a while before merging this.

[amodm]

@phanirithvij in the absence of any confirmation from you, I'll be merging #54 on the basis of my local testing alone, by tomorrow. So if possible, please do give it a test run.

This is now released as v0.8.2

Works! Thanks for the quick fix and new release. Sorry for the late response.
