android init执行service的脚本code位置

 在service.cpp中的Start()调用ExpandArgsAndExecv()

system/core/init/service.cpp

static bool ExpandArgsAndExecv(const std::vector<std::string>& args) {
    std::vector<std::string> expanded_args;
    std::vector<char*> c_strings;

    expanded_args.resize(args.size());
    c_strings.push_back(const_cast<char*>(args[0].data()));
    for (std::size_t i = 1; i < args.size(); ++i) {
        if (!expand_props(args[i], &expanded_args[i])) {
            LOG(FATAL) << args[0] << ": cannot expand '" << args[i] << "'";
        }
        c_strings.push_back(expanded_args[i].data());
    }
    c_strings.push_back(nullptr);

    return execv(c_strings[0], c_strings.data()) == 0;
}

以下面的reboot service为例,ExpandArgsAndExecv()函数args参数为:

/system/bin/sh /system/bin/recovery_test.sh

# service for reboot                                                       
service reboot /system/bin/sh /system/bin/recovery_test.sh
    class core                                                               
    console                          
    oneshot                                
    group system audio drmrpc
