问题 I’m confused by the Debugger. It seems to pause the app and show the Debug window for some breakpoints and not for other breakpoints. It still ticks the breakpoints, though it doesn’t pause the app. And when I open the Debug window I see no frame so I couldn’t look at variables. I’ve looked at many documents and they haven’t cleared my problem. So what I’d like to know are: how frame and thread are related does breakpoint work differently in different place or different class in the app? 回答1:

问题 I needed some sample code to test out the AudioRecord class and I came across this website LINK TO THE SOURCE CODE However the program doesn't run, and hangs after a while. When the program starts it gives blank screen and does not do anything, and after a while a message box pops up saying the program is not responding and whether I want to close it.

问题 I have backtraces obtained from executing the command dumpheap -n <PID> <file> . I have to convert these address to function names and line numbers to make these backtraces meaningful. I used addr2line to convert these addresses to function names. This is the command i used addr2line -C -f -e <libname>.so <address> . There are certain places where addr2line gives me $t in the place of function names but gives the filename:linenumber correctly. How should i resolve this '$t' into function name

问题 I'm switching my development environment from Eclipse to Android Studio these days. And I really enjoy its autocompletion and many other features this IDE provide. However, I have some problem when doing debugging. I hope to use Monitor tool which this IDE provided, self-included DDMS and very nice visual interface to track memory usage, thread condition and so on. But I can't find a way that this could support step by step using breakpoints I have to create (That red dot in editor) I can
