无法从logcat提取堆栈跟踪

Question

I've encountered my first SIGSEGV on my Android app project and I'm trying to get the reason behind this error.

My project is a webapp packaged using PhoneGap and works fine on Android 2.2. On 2.1, it launches, passes the splashscreen, displays part of the first screen (toolbar, fields, but no images) and crashes.

I tried passing the logcat addresses entries to stack.py and parse_stack, but with no success. I must be doing something wrong...

stack.py

macbookair:Dropbox alexandre$ python stack.py crash.log
make: build/core/envsetup.mk: No such file or directory

parse_stack

macbookair:Dropbox alexandre$ python parse_stack.py crash.log
Traceback (most recent call last):
  File "parse_stack.py", line 41, in <module>
    asm, stack = sys.argv[1],sys.argv[2]
IndexError: list index out of range

I'm running this from a specific folder on my laptop (Dropbox in this case), should I be running this in another folder, perhaps the Android SDK?

Thanks!

Answer 1

Even though I did not manage to get the arm-eabi-addr2line command installed, I found out that a Phonegap 0.9.3 packaged app that is using on single CSS file that is minified (all the CSS on one single line) generates this SIGSEGV exception.

The solution: Minify your CSS, but on many lines (you can still remove blank lines, compress colors and remove the last;), just make sure it's not on one line!
