Ffos Nfc Bug V 2.5调试

android 参考：

2.5版的唯一Log，

Log：

351的Log在哪个文件？

可能性如下：唯一的线索

While creating services from category 'profile-after-change', could not create service for entry 'Nfc', contract ID '@mozilla.org/nfc;1'

在创建'更改后的配置文件'类别的服务时，无法为条目'Nfc'创建服务，合同标识'@ mozilla.org / nfc; 1'

卡在创建类别服务时，无法为nfc创建服务，如何才能创建。

先修复如下部分，nfcd---->ipc/nfc通路

grep -rni "While creating services from category '.*', could not create service for entry "
gecko/xpcom/components/nsCategoryManager.cpp:809: LogMessage("While creating services from category '%s', could not create service for entry '%s', contract ID '%s'",

xpcom/components/nsCategoryManager.cpp:876:        LogMessage("While creating services from category '%s', service for entry '%s', contract ID '%s' does not implement nsIObserver.",

xpcom/components/nsCategoryManager.cpp:876: LogMessage("While creating services from category '%s', service for entry '%s', contract ID '%s' does not implement nsIObserver.",

grep -rn "nsCategoryManager.h"
grep -rni MOZILLA_XPCOMRT_API

system/nfcd/src/NfcIpcSocket.cpp
nfcinit

2.2版的添加错误log,
在Nfc.js里添加了console.log(),符号错误时报如下：

gaia setting nfc

正常打开开关

三顺序梳理：

nfcservice::sendcommand

Nfc.js 里的Nfc()

接着定义Nfc.prototype下的原型，用到了sendcommand

也就是let mmm nfcService对象已经分装了sendcommand在里面了.

gecko/js/xpconnect/src/XPCShellImpl.cpp
变量定义，名称替换吗？

一个函数，

.idl文件定义接口C++到ＪＳ

grep -rn getService |grep -v \.js\: |grep -v \.html\: |grep -i getService

接口

添加到Firefox OS

添加js 和manifest文件到

gecko/b2g/installer/package-manifest.in
