I am working with web service using soap parser. I need to retrieve the values from the web service and store it in local. I have lot of string values in it.
My question is, how and where to store all the string values in my application.
Like, this sort of storage normally we use raw folder.
Thanks in advance
Have a look # Android Data Storage
Raw and Asset folders are Read-Only. You cant modify the contents inside, though you can read it only.
In your case, either you should use SQLite database or SharedPreference to save your data. Another technique would be saving your data in a file created inside sd-card, but then you should evaluate the feasibility.

I have a static table around 100 000 records. How should I use realm so that it can save my time? As I know I can put my static table (in case of sqlite) directly in assets and can access it's data.
Is there any way to put static data (rows), so that I can save my time to manually enter the data?
I already used realm's
realm.createAllFromJson("myfile")
But for this I have to put myfile in assets folder, and I guess it will need double the disk space.
There are two restrictions why this is impossible now.
Any sqlite database is stored inside a particular path:
'//data/data//databases/'
To get access to any database you have to use a path
You can only get data from assets (or raw) in order to copy to somewhere. This is not possible to manipulate with SQLite without namely 'file' data.
That's why you have to copy data from app resourses into filesystem. Imho, this is ugly but I had not found another solution.
Android default API (Realm uses it) use only the files stored in 'databases' folder.
My app collects data which it stores in arrays, and I need to be able to access the data from outside the app. The tablet I am using has no SD card, so I'm thinking the best way to transfer data would be to save to 'external' system memory. I have found tutorials to save data on internal storage and for specific data types like pictures onto SD cards, but I can't figure out how to write an arbitrary file to an arbitrary location. Thanks.
This sounds like a perfect time to use a SQLite database. Android comes with SQLite support built in so its easy to set up. You can just create a database and store your array data there (you can even store pictures too as a byte[]). There are a number of tutorials that show how to do this. Here is 1 and 2. It should be pretty easy from there.
I'm not sure that you can write to an arbitrary place on the Android system. You could write to a file in /data/data// and then email that file to yourself.
What is the most appropriate way to store some structured texts?The texts will be a collection of "books".each book contains a collection of articles,and each article has a title and a body.
The ways i could think of are:
create a database using sqlite
write an xml file in assets
put them into res/value/string
use java string
which method is the best for my situation?is there a better way other than those ive listed above?
Thanks in advance.
=========================
edit: Yes,the data can be regarded as static.
XML, or any other format you prefer in res/assets is the preferred way, if your data is static (it won't change).
If you want to work with dynamic data gathered from a webapp for example, then you should use the built in SQLite database.
If you're looking for persistent storage then I would suggest a small SQLite database. You could also store it in XML documents and then use a ContentProvider to abstract your access to the books, but then you would have to write the I/O and XML-parsing operations yourself.
Basically, I'm trying to store some data (~300 rows, ~10 columns) for an android app. This data will not be changed by the app, just used in calculations and stuff.
However, everything I've found online (example) talks about using a database that is created at runtime. I do not want this, the data will be the same every time the app is run.
So is there a way of using a databse like this? (Or any other way of storing data in a table-like fashion?)
Generate the SQLite database as part of your build and keep it in your app's raw resources. Since all you need is the file's path and name to open it, you can still read it fine. Your open helper will still go through onCreate() the first time unless you include the table Android uses for its own bookkeeping, but that should be okay.
Make sure you only open it for reading, and you should be good to go.
Put your custom file in the assets folder under the project root.
To get a inputstream from the file, just do:
context.getAssets().open(file);
In this way you can store your static data in conma separated or any model you want.
If you want the data constantly changing, you can create a temporary file in the SDCard, by accessing and creating a new file under some path at:
Environment.getExternalStorageDirectory()
How about storing this data in raw file under Assets or Res/raw folder. You can either dump this data on the fly in Database or read it and process it [which may be costly]. Dynamic handling may be costly, test it and compare performance.
Is it a good idea to save user generated values in a .xml file in the res values folder?
The values look like "Aircraft", "Type", "Note" in one row. Is it even possible to save Values there while runtime and is it possible to save there a multi-part value?
I just want to know, what's the most recommended way to save a three part value, to show it in a Table (table layout).
First of all android .apk file is read only so you can't store values in /res directory at runtime..
You an store these values in Shared Preferences, Xml file and then it in internal storage or sdcard and in SQLite database..
Now you have a multi-part values, and you want to display it as a table layout format, So I think SQLite database is useful for it..
Now choice is yours..
If your amount of data is small, you can consider using SharedPreferences.
Else, the prefered way to store persistent data is using a SQLite database I think.
You can't save values to res folder at run time. you can store those data in Shared Preference or in SQLite database or
