關於4.0的Wi-Fi Direct

剛剛照著developer.android.com/resources/samples/WiFiDirectDemo的做法做出他的程式
使用兩台裝置互相搜尋，結果因為WiFiDirectActivity.java在Menu中有設定能開啟Direct
狀況：平板的可以很順利開啟，但Sony的手機就...選項呢???
結果：因為Sony的"不清楚"是否有開啟Direct連線(我的平板是搜不到東西的)，然後我又沒有第二台非Sony裝置，所以不了了之...晚點看朋友的支援設備有沒有出現(眼神死)
來這發結果算是給這串文一個結尾，引免以後有人走上同樣的路又跟我一樣

system\etc\permissions\android.hardware.wifi.direct.xml
这样就出来wifi direct选项了。。
然后不知道怎么弄,sgs2无法搜索arc
android.hardware.wifi.direct.xml
