整個無言…google play store 問題… 網路上最多的是root，砍 對應錯誤程式的資料夾….手機現在不見得會root了 所以建議，把android的同步開到最大，先同步備份一次，然後把手機還原吧！ 記得一個小問題，本人碰到的，因為一開始有插sd卡，結果還原時，android把程式還原到sd卡上，所以先把sd拔了，還原完，再插sd卡………….我覺得可能是我搞錯，…..但懶得查了…反正就這樣做

firebase response Great question. We are actually putting the finishing touches on login v2 and I think you will be happy with the offline improvements it brings. Ultimately, you are running into issues with what you are trying to do because it cannot be done with the current API. However, with our upcoming login refresh, we will persist session tokens on the client, allowing you to authenticate via custom or simple login without any internet connection. We are still a couple weeks out from finishing this project and making it production-ready, but keep an eye out on this group for announcements. ...

Now P2P is too good, so use QOS can’t stop. So 1、 setup limit connection：in Firewall, Filter Rule add Action: drop Protocol: TCP UDP Extra-Connection Limit: xx 2、set connection timeout: in Firewall, Connections, Tracking-TCP Established Timeout: 00:05:00 (5mins by your want) then……p2p……can use, but…..you know

剛用intel XDK 做crosswalk，用codova，做純網頁 app，非常慢…..慢到極點了 crosswalk是把最新的chorme的核心，包在apk中，只有4.4才是內建chorme新的核心，所以crosswalk就是把apk包了chorme，讓apk走html5架構暴快 如果單純crosswalk比cocoonjs還快，目前看有人測試，所以是慢在codova….. codova太慢了，如果用android studio 做原生的webview，連網頁超快，但我現在手機，雖然是4.2，但底層已換chorme，所以我測很快，所以現在兩種情況： 一、以後走4.4後，chorme為底層broswer時，html5暴快， 二、等android studio可以包crosswalk時，就算4.x的都暴快，4.0以下不能用crosswalk，但包了crosswalk會胖20 MB 但，很妙的是，如果走codova crosswalk XDK，放到手機中，吃的記憶體不多，5x~8x MB，但會自動掛掉 …….
