Debugging a panic?
$ adb logcat | grep RustAndroidGlueStdouterr

01-16 10:47:43.492 9610 9626 D RustAndroidGlueStdouterr: note: Run with `RUST_BACKTRACE=1` for a backtrace.
Is there a way to either get the backtrace, or run gdb/lldb remotely?
You can do something like std::env::set_var("RUSTC_BACKTRACE", "1") to get a backtrack on the logs.
It's probably possible to plug gdb in but I'm not familiar with that.
I got backtraces to kind of work, but using android's built in stack straces

This backtrace is somewhat readable, but it lacks more debug information (Like lines and files).
On a separate note this is still not good; I generally use cargo apk run --release because my app happens to be unbearably slow on debug, and even with
[profile.release]
debug = true
I still don't get debug info at all.
