如果确定库没有问题，他们需要调整静态库的前后顺序，或者加上如下编译选项LOCAL_LDLIBS := -lz

mkdir /data/coredump_log write /proc/sys/kernel/core_pattern "/data/coredump_log/core-%e-%p" write /proc/sys/kernel/core_uses_pid 1 setrlimit 4 67108864 67108864

根据报错信息可以看情况添加LOCAL_CFLAGS += -Wno-unused-const-variable -Wno-unused-variable -Wno-unused-parameter -Wno-format -Wno-sign-compare

IPCThreadState::self()->getCallingPid();

使用busmonitor测试内存带宽些内存带宽占用程序：int main(int argc,char *argv[]){ char* buf = (char*)malloc(MALLOC_SIZE); if(buf == NULL) { printf("malloc failed\n"); ...
