What's the easiest way to populate a SQLLite table with data off a URL?
I'm writing a Delphi web app that will generate a file on a server for my Android app to download.
In Delphi, I'll probably save it as a .csv file and use bulk import to import into MS SQL Server.
What's the easiest / best practice way to do this in Android? How would I download the file from the URL and then load it into SQLLite?

I'm kinda new to android programming so please bear with me. I'm having some problems with retrieving records from the db. Basically, all I want to do is to store latitudes and longitudes which GPS positioning functions outputs and display them in a list using ListActivity on different tab later on. This is how the code for my DBAdapter helper class looks like:
public class DBAdapter
{
public static final String KEY_ROWID = "_id";
public static final String KEY_LATITUDE = "latitude";
public static final String KEY_LONGITUDE = "longitude";
private static final String TAG = "DBAdapter";....................
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_list);
mDbHelper = new MyDbAdapter(this);
mDbHelper.open();
fillData();
registerForContextMenu(getListView());....................
The date is actually stored as an int in the SQLLite database, and thus it displays as an integer. Does anyone know a way to create a date from the int so it doesn't display as 1216544611 (or whatever) but as "12/11/2009 11:32"?

I think i'm getting senile because I was convinced that to give a name to your application, you had to fill this part of the manifest: <application android:icon="@drawable/icon" android:label="MyApplicationName"> However for a reason I don't understand, my application gets the name of my first activity, in which I load data, henceforce, It is called "Loading"...(defined as follows in the manifest) <activity android:name="AccueilSplash" android:label="Loading">
View 2 Replies View Relatedi am fetching XML from the web, parsing it and display it on the screen. The problem which i am getting is that the activity tries to load the data from web each time the activity is called.(Actually, my mobile app requires frequent trips to the server) So i am in search of the below solution: On Re-launch of an activity, the data from web should not be loaded again. (But it should load data from the cache or local database that we have created while calling the web-xml for the first time). creating a class that i can use to transparently make application faster by selectively caching items in memory. And thus, making users very happy and This class can even apply individual refresh times to each cached item.
So, i think i need to store the data in Cache , or in local database or something like that. Is there any way/technique to implement such thing ? so that it need not to load from web every-time on Re-launch of an activity. [Note: I want to do to make client happy by decreasing the loading time and running the application efficiently and optimizing application's loading time]

View 2 Replies View RelatedI have a widget that supposed to call an Activity of the main app when the user clicks on widget body. My setup works for a single widget instance but for a second instance of the same widget the PendingIntent gets reused and as result the vital information that I'm sending as extra gets overwritten for the 1st instance. So I figured that I should pass widget ID as Intent data however as soon as I add Intent#setData I would see in the log that 2 separate Intents are appropriately fired but the Activity fails to pick it up so basically Activity will not come up and nothing happens (no error or warning ether)

How to load data in expandable List Adapter through Scroll .
Means I want to add data as per Scrolling in Run time.
My app is made of two activities, A and B. I'm considering this sequence of steps: Activity A is started. A launches B [A is paused, B is running]. B launches a map intent [A and B are both paused now]. Now the user is using the maps application and the system decides it needs more memory. Can the system kill only one of my activities for memory, or will it always kill all activities in a "process" in this situation?
Both activities share some static data like:
class Data {
public static String mName;
public void save() {
// write to file: mName;...................

I would like advice from those with 2.2 on Orange. I've had my Desire for 2 months now and love it-apart from one thing-the damned Internet connection. Quite often, with a strong 3G+ (HSDPA) signal, my internet connection fails to load data. Then, a few minutes later, in the same location, it works perfectly. I know for a fact that this is not a network only problem. The reason I know this is because I previously used the exact same SIM in my iphone for 6 months in the very same locations and it always worked perfectly.
Therefore, my strong suspicion is that the problem is a result of the combination of the Orange branding on a Desire and the network itself. I'm sure I read of a couple of posters here who had the very same problems and when they moved to 2.2 the problem disappeared. Can anyone confirm? I've been waiting patiently for the Orange update to 2.2 but am getting fed up and I'm concerned that the Orange bloatware may still cause an issue after this. Hence, I'm considering a debrand and update myself.
I would like to store an object into a SQLlite database. I am looking for how to best do it in order to ensure that if I need to updata/change this object in the future that users of the new and old object layout will be minimally impacted. In other words I want to ensure that making changes to the object will have minimum affect on clients that do not update their software on the old database format.
I want to also ensure an easy update from the old record style to the new format. I was thinking that I could add an element in the SQL row to identify the object type with a unique name, and to identify the object version number. That way I could read the row and use the object number to control the deserializer to use the correct version of the class.
Has anyone got an example of how to write a ContentProvider that gets its data from somewhere other than a SQLLite database? Mine is half working, in so much as I can retrieve the requested data and apparently populate a MatrixCursor, but I can't figure out what I'm supposed to do with the 'projections' parameter supplied to the 'query()' method.

View 4 Replies View RelatedI'm a .NET developer starting to dig into an android application. One thing that seems a little abstract is working with SqlLite. In a .NET application, I can do my Database setup, query testing and profiling, and enter in some test records through Management Studio for MSSQL. In fact, I'm constantly in Management Studio checking something - so I'm finding it difficult to work without a similar tool.
What are some good tools/tricks to use when developing SQLLite on Android? The tool doesn't have to have a GUI, but would be nice if I could run it as a desktop app and have it look at the same DB as my emulator.
For instance, something that will allow me to run a simple SELECT statement against a table to view records without having to do it through android?

View 1 Replies View RelatedI have been assigned the task to use an android tablet to run a single app in an enterprise setting.

View 2 Replies View RelatedIs it possible to load a layout XML at runtime and load into activity?
In my app, I have various types of data like Person, Company, City, etc; The requirement is to dynamically load the layout, find views by tags (property names like Person.name, Person.address) and then fill in data. For example, if user has selected an object of type Company, we want to load a company.xml layout, inflate it and then associate various properties (company name, company slogan, city, address, revenue) to tagged views. One possibility I see here is - each view in the layout will be associated with property-name as tag and then appropriate data will be loaded in appropriate views.
What should be the best design you would recommend?
I am working on building an android app but I'm nothing that my SQL operations are taking forever to complete
I have profiled the app to narrow it down to the act of moving the Cursor to the first row of the result set for a simple select query (only returning 1 row where I'm testing it to eliminate the size of the result set as a problem.
Are there any better options for moving to the start of the result set?
edit:
some code...
this runs 3 times and i have time it to approximately 2 secs for all the rest of the code or over a minute with this in.
i have also run just the rawQuery statement with out the move to first and its takes bout 18 secs so im looking at the worst part of the code first.
I have created a program, with a service - the service is "START_STICKY". So when i close the program (i am using Advanced Task Killer, to kill programs) the service is restarted automatically, but this presents a problem cause i get an error when trying to call ContextWrapper.openOrCreateDatabase(ContextWrapper.java:203) (see stacktrace below).
I have created a class to handle context, which will return my Activity's context if it is not null, or a fake one i created if the activity's context is null - and the activity's context is null so the fake one is used, i suspect this may be the problem, but have no idea.
In my activity i have a constructor which gives a reference of it self to the contexthandling class, but it seems the activity is not instantiated (not before the service is started at least) when the system is restarting my service.
There is of cause no problem when the program is just started normally, the service starts fine then... which is why i am suspecting the fake context, i created it as follows (and it is referenced in the manifest application tag with android:name=FakeContext):

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.
