RustAndroidGlueStdouterr: fatal runtime error: failed to initiate panic, error 9 RustAndroidGlueStdouterr: stack backtrace: Here's some sample output with the usual logcat stuff cleaned out: RustAndroidGlueStdouterr: thread '' panicked at 'explicit panic', src\drawable\water.rs:59:29 On Android/NDK, on crashes, even if you don't get full stack trace, can you at least get a file name / line number before program dies? Then I can print out a file name / line number before it dies. In wasm32, I use set panic hook to capture panics. If you've any more questions please let me know I'll try to answer them based on my experience. I'm not quite sure what you mean by the android 'native' API, since there's the NDK (native development kit), and the JNI (java native interface).Ī noteworthy point to make though is that given the progress made in cargo-apk, I can have a java-less codebase, so I don't have to juggle languages. And since egl isn't a very nice interface to work with, I was left with println debugging. I was stuck trying to debug an glutin for a week only to find it was a debug flag that was wrecking everything.
The biggest obstacle in developing on Android I have faced is not knowing what the obstacle was.Which can unfortunately lead to some ugly code. Because, as mentioned earlier, the NDK provides essentially event handling, the rest, more complicated things you'd want to do are left up to you using the JNI.You don't get stack traces on panic they're either obscured by release mode, or unattainable because of a bug in android, so either println debugging or an actual debugger are necessary.Optimizations are important, without them the rust code unfortunately doesn't run very fast.I currently use a locally modified piston clone. It's a very barebones interface that is exposed by the NDK, meaning you need to do everything from loading OpenGL ES to writing (or using a preexisting) gui/drawing library.I don't know how it would have worked in Java, but there are a few things I'd like to note:
I'm currently working on a personal project which uses android/rust.
