Tried it; no change. The code path in the VM is essentially the same. Either the "throw" instruction or the "divide integer" instruction is going to post an exception, and the common code in the interpreter's exception handling is what posts the exception to the debugger. The VM does filter the exception against the rules the debugger has provided (e.g. "class is an instance of RuntimeException", "caught or uncaught exceptions"), but that bit is pretty straightforward. > BTW, a documentation suggestion: Most of the stuff in the Dalvik > Debugger Support document you pointed me at is only going to be of > interest to geeks like me, but some of it is helpful for anyone trying > to debug -- [...] > I think a brief article with the highlights -- including points like > the debug protocol being debugger-agnostic -- would be a good addition > to the developer documentation.

Values would appear and disappear in ways that drove people nuts. "dx" will generate more efficient code in some circumstances if you disable the debug info. The fancy documentation was written (or at least edited) by tech writers. The stuff in dalvik/docs was written by engineers (e.g. debugger.html is mine). This is probably noticeable in both content and presentation. :-) I can forward your suggestion. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
