解包大型apk文件,可能会出现如下错误,
UNEXPECTED TOP-LEVEL ERROR:

这是由于Linux文件数限制导致的错误.
可以使用Ulimit -a查看:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 20
file size (blocks, -f) unlimited
pending signals (-i) 16382
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) unlimited
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
解决的方法就是提高这个上限数,切换到root账户,执行ulimit -n 4096
然后就在root下面执行baksmali就可以.
如果在root下没有java环境,只要source一下java环境设置就可以了.例如我的环境设置文件为:
---------------setup.sh------------------------------
JAVA_HOME=/opt/jdk1.7.0_71
export JAVA_HOME
ANDROID_JAVA_HOME=/opt/jdk1.7.0_71
export ANDROID_JAVA_HOME
PATH=/opt/jdk1.7.0_71/bin
PATH
export PATH
只需要source setup.sh就可以了,这是因为只要离开root账户,或者重开terminal, ulimit的设置就无效了.
