Is there a way how to get trafficStats from some date? For example from last month.
I´m using this Get wifi traffic stats android and as u can see from the code there is only number value of traffic in this file, but for example in DroidStats app data are counted from last day/month etc.
Also value is always 0 when i reboot my phone or when i´m messing up with settings of network is there another file somewhere or do i have to store this data myself if i don´t want to lose them?

You would have had to have been running last month, collected the data yourself, and saved it to a database or something. TrafficStats does not have any history. It only reports current cumulative values, except for resets (e.g., reboots).
Also value is always 0 when i reboot my phone
Correct. This is working as intended.
do i have to store this data myself if i don´t want to lose them?
Yes.

I want to calculate the amount of network usage/network traffic stats for my app in a month.
I can use TrafficStats to provides network traffic statistics, but the statistics returned by this class reset and start from zero after every reboot. I think about storing the statistics on the storage, but I want another way.
So I change to use NetworkStatsManager to calculate, but most of method required API >= 23.
So how can I do it with api below 23? Thank you.
you should persist the data from traffic stat in sqlite at some time interval. And store the last reading just before Shutdown using
action android.intent.action.ACTION_SHUTDOWN in broadcastreceiver. After restart, you should start storing the data again. This way, you will not lost the data. The solution works on all android version.

How about storing this data somewhere? E.g. in SharedPreferences, SQLite database or somewhere else. After that, your data will be persisted after reboot and you can accumulate the calculated results.
Even if we persist the data in sqlite, it is not necessary that the value is reset to zero after shut down of device. In that case there is confusion whether to add the previous stored bytes with the value that we get after reset, because the value is not always zero after shut down.
I have an app which is used for collection all day users collecting amount normally offline and then in the evening they uploaded amount online. Sometimes there device date and time is inaccurate so they uploaded wrong data.
At the time of collection my app is getting date and time from the device. Is there any way that app always store accurate date and time without Sim and without the Internet.
You can create a Sqlite Table in application cache when user switch on data,you
can save current server time in that Table and in offline mode you can compare server time with current time. this is the nearest approach to get accurate time
Well, before searching for an app to do this. As a human how can you tell if the date/time is correct without internet?
A possible solution would be a service which counts seconds from the last time the device was connected to the internet (which means it had a correct date/time at that moment) then when you want to add the new amount you can add the seconds to the last time and store this value.
Edit
You will 2 things to achieve this:
BackgroundService
Counter which you can achieve in many ways, I would go the easy way. check this: how-to-measure-elapsed-time
Or you can have an AlarmManager to do this.
One more thing You need to be careful if the device goes off or for some reason, something stopped the service. All of these are user issues and you need to decide how much you want to handle stuff for the user.
You can fix user mistakes by pushing to a SqlLite database every 10~15, but this won't fix if the device went off for hours and then started again at a wrong time - I don't think there is a possible solution for this-.
here is what i'am trying to achieve, either one of the two would be ok
Get the date and time from a specific url/website like "www.mywebsite.com"
Get the date and time from my MSSQL Server
either one of the two would be ok, because all i need is to get the same time from the website/server's end, because i'am making an APP Version for the Mobile Website i'am making and i want to show a Clock or Date&Time Reminder in the App
i have no codes working as of now, i tried searching online in search engines and also in stackoverflow but i can't seem to find what i'am looking for, either i'am using the wrong words to search for it or there really isn't any way
the reason why i need the date is because i'am checking when the records inside the database was created and verifying how much time has passed since it was created, it like comparing (CreationDateTime & CurrentDateTime)
i can successfully Display how many hours have passed, i just need the CURRENT PROPER & ACCURATE DATE & TIME of the server :)
I can't help but think this is an XY problem, or at least close to it.
Your client device knows what time it is, because it stays in sync via NTP and whatever network it's attached to (and we already know you're attached to a network because otherwise, this whole thing falls apart). And it knows (or should know) what timezone it's in, so you can translate that to UTC or whatever alternative timezone you might need.
Your server(s) should also be keeping time synced via NTP, so drift between the client and server should be sub-second at worst.
IOW, the time (when corrected to UTC, which all date/time libraries I've used have a method built in to do) will almost always match between your client and server, so why bother with the complexity of "pushing" the current time from server to client?
I'm not seeing why you'd need to do this at all. Have the server tell the client when the reminder is set for, then let the client work out the rest. Anything else would be excessively chatty over the network.
To get the date in the format below, just convert todays date to a string
--07/06/2017
SELECT convert(varchar(10), getdate(), 103)
i have found an alternative answer that works 100% in getting date and time from SERVER instead of URL
SELECT GETDATE() AS CurrentDateAndTime
GETDATE()
I am trying to get the exact Data Usage per Day , or by Range of Time in Android
however from what I searched, I cannot found anything that could do this
Something that I tried
TrafficStats
this one will reset all data every time the device is boot, so I
couldn't use it
NetworkPolicyManager
this one require system permission. So, I can't use it
any help would be appreciate
You need to have a service that will periodically call TrafficStats APIs to get current statistics, and store the results. E.g. the delta between two invocations of getMobileTxBytes() is the number of bytes received during that time period.
Of course, if someone just pulls a battery out of their phone, you'll lose statistics since the last invocation of your service. So set the frequency of updates according to your needs (every hour versus every minute).
I would like to get some help about getting 3G data statistics between a date interval.
As far as I know, I should use TrafficStats (Android api 2.2 or higher). I would like to save this information into a SQLite table to show statistics for apps monthly:
Interval date: 01/01/2012 - 31/01/2012
Google Maps - 1,5 Mb
Google Talk - 0,9 Mb
Facebook app - 5,6 Mb
So, I Think I should use a background service. Is this the best way? How should I try to do it in the background service? How do you think I should save the information in SQLite?
(#Pabloku, sorry this answer is coming so late, hopefully it will still be of some help)
Firstly, if you're looking to get traffic stats for individual apps, but only on 3G, it's not possible using public APIs. Android provides the TrafficStats.getUidTxBytes(int) and TrafficStats.getUidRxBytes(int) as public APIs to get the total number of bytes used by apps, but nothing (public) to separate them by interface.
Assuming this doesn't ruin your day, here is a pseudocode algorithm for how to do the rest of what you mention:
Set an alarm if necessary (using AlarmManager) for the start of your range, and store these values (presumably in a DB). Reason: you may need to subtract these existing TrafficStats values as an offset if they are > 0 at the time your date range starts.
Also set an alarm for the end of your range.
Create a BroadcastReceiver to receive ACTION_SHUTDOWN.
In your BroacastReceiver, note down the TrafficStats for your app(s) at shutdown. Reason: TrafficStats will get reset on every reboot.
If this is the first shutdown since start: subtract your initial offset and store that final value (being careful to remove the initial offset)
Otherwise, whatever value is reported will be accurate since boot.
Once your end alarm is triggered, note down the TrafficStats at that point, and add all previously collected stats
(if somehow the phone never rebooted between start and end, just do endStats - startStats).
Good luck!
