ANR with Google Analytics when purchasing the in-app-purchase items

     昨天suffer了一個離奇的deadlock issue，情境是如果User已經買過某個IAP Item後，重複購買時有些Device就會卡住然後ANR，結果dump出來Thread的狀態後發現，結果Main Thread卡在在GA回報Crash的Task。

stackoverflow有人建議直接把它回報crash的功能關掉（專心做event的事情就好了啊GA）

The Free Translate API from Google

   The google translate api is not free in v2. but some way(hack) let it's work. we can sniff the Google Translate. and mimic the request, the example show as follow:

main.py

TRANSLATE_URL_PREFIX='http://translate.google.com.tw/translate_a/t?client=t&hl=zh-TW&sl=en&tl=zh-TW&ie=UTF-8&oe=UTF-8&multires=1&prev=enter&ssel=0&tsel=0&sc=1&q='

# the user agent is neccerry ...
query = "THE WORDS YOU WANT TO TRANSLATE"
user_agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.93 Safari/537.36'
headers = { 'User-Agent' : user_agent }
req = urllib2.Request(self.TRANSLATE_URL_PREFIX+query), None, headers)
res = urllib2.urlopen(req)

r = res.read()

while ',,' in r:
    r = r.replace(',,',',')
content = json.loads(r)
result = content[0][0][0]) 

The most trick is the response JSON is invalid. we should remove the wied tag : ",,".

hope it's help for you :)
