2.2修改后的预期错误log
357:I/GeckoConsole( 180): While creating services from category 'profile-after-change', could not create service for entry 'Nfc', contract ID '@mozilla.org/nfc;1'
358:I/GeckoConsole( 180): While creating services from category 'profile-after-change', could not create service for entry 'NfcContentHelper', contract ID '@mozilla.org/nfc/content-helper;1'
（１）
vim xpcom/components/nsCategoryManager.cpp
（２）同2.5，两个manifest 文件有问题。
NfcContentHelper.manifest:7:category profile-after-change NfcContentHelper @mozilla.org/nfc/content-helper;1
gonk/Nfc.manifest:10:category profile-after-change Nfc @mozilla.org/nfc;1
nfc.manifest
推理猜测：
执行了某个js 文件然后log出来了。
就是认为没开启任何东西，他们就建立好连接了。
一开机就有连接好
