1 抓log打印
LOGCAT 打印出debug打印如下：

2 提出部分log存入error.txt
#00 pc 00011862 /system/lib/libGLES_android.so

#02 pc 00019b6c /system/lib/libsurfaceflinger.so
#03 pc 00019f18 /system/lib/libsurfaceflinger.so

#05 pc 0001dd20 /system/lib/libutils.so

#07 pc 0000c494 /system/lib/libc.so
#08 pc 0000c034 /system/lib/libc.so
3 前辈总结出来的脚本 hy.panic.py
#!/usr/bin/python
# stack symbol parser
import os
import string
import sys
#define android product name
ANDROID_PRODUCT_NAME = 'generic'
ANDROID_WORKSPACE = os.getcwd()+"/"
# addr2line tool path and symbol path
addr2line_tool = ANDROID_WORKSPACE + 'prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-addr2line'
symbol_dir = ANDROID_WORKSPACE + 'out/target/product/' + ANDROID_PRODUCT_NAME +'/symbols'
symbol_bin = symbol_dir + '/system/bin/'
symbol_lib = symbol_dir + '/system/lib/'
class ReadLog:
def __init__(self,filename):
self.logname = filename
def parse(self):
f = file(self.logname,'r')
lines = f.readlines()
if lines != []:
print 'read file ok'
else:
print 'read file failed'
result =[]
for line in lines:
if line.find('stack') != -1:
print 'stop search'
break
elif line.find('system') != -1:
#print 'find one item' + line
result.append(line)
return result
class ParseContent:
def __init__(self,addr,lib):
self.address = addr # pc address
self.exename = lib # executable or shared library
def addr2line(self):
cmd = addr2line_tool + " -C -f -s -e " + symbol_dir + self.exename + " " + self.address
#print cmd
stream = os.popen(cmd)
lines = stream.readlines();
list = map(string.strip,lines)
return list
inputarg = sys.argv
if len(inputarg) < 2:
print 'Please input panic log'
exit()
filename = inputarg[1]
readlog = ReadLog(filename)
inputlist = readlog.parse()
for item in inputlist:
itemsplit = item.split()
test = ParseContent(itemsplit[-2],itemsplit[-1])
list = test.addr2line()
print "%-30s%s" % (list[1],list[0])
4 将hy.panic.py跟error.txt放在android编译根目录，执行python hy.panic.py error.txt即可到处堆栈
python hy.panic.py error.txt
read file ok
primitives.cpp:688 _ZN7androidL13lerp_triangleEPNS_2gl15ogles_context_tEPNS0_8vertex_tES4_S4_
vertex.cpp:214 glNormal3f
DisplayHardware.cpp:167 android::DisplayHardware::init(unsigned int)
DisplayHardware.cpp:81 DisplayHardware
SurfaceFlinger.cpp:203 android::SurfaceFlinger::readyToRun()
Threads.cpp:753 android::Thread::_threadLoop(void*)
Threads.cpp:127 thread_data_t::trampoline(thread_data_t const*)
pthread.c:207 __thread_entry
pthread.c:343 pthread_create
住：以上为根据前辈的帖子总结!
