Android Question Data from server

[hookshy]

Hi,

Please help me understanding how can I make app with data to be refreshed each day from a server.
What are the methods to upload data within the app ?

One method I know is to have mysql database and I failed to make the libs work with all the nauty mysql services.
Do you know other simple stuff to make app get data daily from a remote host ?
Parse.com was a blast and easy to use for everyone , is there other easy stuff like this one ?
Any other libs or services that you know ?

Thank you !

Take a look at my php/MySql examples (see my signature). Very easy. It uses OKHttpUtils and a php script. No other libs needed and: Most servers support it.

Just put your HttpJob in a service than StartService after 24 hours. You need to check there's internet connection or not. If not retry after 30 minutes or longer.

Ok... If it's just a file you can download it every day with Job.Download2. Otherwise use B4J on your server if your hoster allows that.

PS: When I was 1 1/2 years old I didn't know how to walk or to speak. But I learned it...

Additional you also can use
- Firebase Storage
- Dropbox, Box, GoogleDrive
- Depending on the data you probably can use CloudKVS
- FTP
- Depending on the data you probably can use Firebase Realtimedatabase

There are a lot of possibilities

Use RDC. If it does not involve images/blob data (which you would otherwise store on disk - rather than blob), it is quite easy to do - when you know what to do...
I do this with all my tables in my app. It determines what is new on the server and refreshes my mobile app with 'new stuff'.

First, your server table(s) need to have an updated field (MySQL Timestamp). This field gets updated each time the record is updated/modified on the server (or when new data from mobile updates it - if shared). When your mobile app last updated it's tables from new stuff from the server, it should update a local table with a time-stamp of when THIS table last updated. This is your check if it needs to be done again.

Have your mobile app check each table's LAST update record to see if new changes exist on the server. If new data on server exists:

1. What I found is most practical...
DROP the local table, recreate it and insert EVERYTHING from the server. This way, you don't have to deal with updates, new inserts or deletes. Everything from the server gets into your local table.

2. Manage updates, inserts, deletes in your own fashion.

Note: Option 1 works great when dealing with a small amount of records/data.. (under 5 meg - configuration data )... Otherwise bandwidth and cell costs (data plans) may be an issue depending on how often it is invoked. (Wifi - no concern).

Your question has HUGE implications depending on your actual needs/environment. There is no "one solution fits all". These days it all depends on how much you (or your customer) is willing to spend in data transfer costs - when on cell (eating up your 1 gig/month/device plan) - which most rely on now.

Think about it...

I need only data tables, no pictures ..so it would be more easy to figure how it the best way to do it
