BTW,What I expect to see is a stack trace with file name and code line 
number,but when using "printf("%s",1),they're missed.

Your entire stack is in system libraries. You don't have symbols for those 
system libraries, so you're not getting a useful stack. I don't think there's 
anything Breakpad is doing wrong here. You can pull the libraries from the 
device and run dump_syms against them to get symbols for them, although that 
still might not get you a fully useful stack.
