假設我有兩個不同的應用程序A和B.從device_id和device_token創建數據庫。哪個組件是唯一的設備ID或設備令牌?
如果我在IOS, Android, Window mobile
安裝這兩個應用程序。安裝後, 然後我卸載這些應用程序,然後重新安裝IOS,Android和Window移動然後which component is unique device ID or device token
?
A and B:
IOS: device ID or device token??
Android: device ID or device token??
Window: device ID or device token??
我怎麼能區分A和B應用在每臺設備上安裝獨特之處?
我創建數據庫:
id, platform (1=> android,2=> ios, 3 => window), request_coming_from (A=> A app, B=> B app), device_id, device_token, created,modified
1, 1, A, ????, ???? , 2016-07-07 12:02:34,2016-07-07 12:02:34
2, 1, B, ????, ???? , 2016-07-07 12:02:34,2016-07-07 12:02:34
3, 2, A, ????, ???? , 2016-07-07 12:02:34,2016-07-07 12:02:34
4, 2, B, ????, ???? , 2016-07-07 12:02:34,2016-07-07 12:02:34
5, 3, A, ????, ???? , 2016-07-07 12:02:34,2016-07-07 12:02:34
6, 3, B, ????, ???? , 2016-07-07 12:02:34,2016-07-07 12:02:34
每次應用程序的每個設備也將達到一個API和開放從中 我將存儲平臺,request_coming_from,DEVICE_ID,device_token以及創建和修改日期的系統的當前日期時間。
If you have any idea and effective way to store device_id and device_token in database?
使後我可以計算移動臺的應用程序(A & B)的多少nuumber 安裝在不同的移動(未同一移動。)
實施例:
Mobile (M1 - android):
A is install
Mobile (M2 - ios)
A is install
B is install
Mobile (M3 - ios)
B is install
Mobile (M4 - window)
B is install
產量:
A =>
1=> android
1=> ios
B=>
2 => ios
1=> window
