I want to know how can I get the number of records (rows) in a specific table in my db. I need this so I can create a loop to go through every record and add each one of it to the specific Array and display it later on.

I have a 800 kb xml file on a server. I download it, and parse with a SAXParser.
And then i add all item elements to my SQLLite db on the phone.
All item has 50-60 element.
One insert query take about:
11-18 21:15:54.079: ERROR/448 delay_(9169): 41207
11-18 21:15:54.099: ERROR/448 delay__(9169): __ 41223
about 20-90ms , i have 500 row, and it takes 40 minutes, it is a good value for this?
How i can do it faster? Is it possible?
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";....................
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.

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'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?
Hi. Can someone please tell me how can I easily display every record from sqllite in ListActivity tab? I'm kinda confused with this. Do I have to create db from my helper class in TabActivity or ListActivity or both? My db helper class is as follow,,.

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):

View 2 Replies View RelatedI would like to know whether its possible to record call in Android. If its possible then which class should be used for that purpose. I think there should be some message broadcast receiver invoked when a call is accepted and application should be started in background and record the conversation. Would like to know if this is actually possible and it it is then what classes to refer to?
One more thing if I want to send the recorded file to a server through GPRS then is there any limit in size for it to get transfer through GPRS? Small files will be transferred easily through GPRS but what about larger files? Is there any upper limit as to files of this much size can be transferred.
More importantly I want to know about the call recording function. Whether its available in Android phones as a native applicatoins or not? If its not available then can a application be written that can record all incoming and if possible outgoing calls as well.

View 2 Replies View RelatedI am using the excellent Record It utility to allow me to send record instructions to my Sky+ box. All was well until the last update, where version 3.6.0 was corrupted in the Android Market. I have spoken to the developer by email and the problem has been fixed now. However, whenever I try to download now, the download fails, and Market FC's when I cancel the download. I have managed to find an old version I had backed up, but I am now stuck at v2.7.3. Can someone post the apk for version 2.8.0 please? I have asked the developer, but he did not reply. This is a paid app, and is linked to the phone ID, so I am not trying to install without paying.

I have an screen that displays all the names in the Contacts in a ListView. When the user clicks on a name, I want to launch another Activity which display the details of the selected Contact (Phone number/ email) in another screen. How do I display details for the selected row. (i.e When starting the intent how do I send over the row_id of the item selected)?

I'm a developer looking to create an Android application to record phone calls. This spawned out of my own personal need to record phone calls for my own purposes and for my records. Is it possible to do this? Is it possible to get access to the microphone and what's coming through the speaker? I'm kind of new to Android development, so bear with me :) I assume that I could probably record into WAV and then at the end of the call, transcode it into MP3 using LAME or something. This may kill the battery, but this seems like a good project for me to get used to Android with. I'm looking to use Android 2.X.

View 2 Replies View RelatedIs there any app to record phone conversation on the fly. I searched some threads but didnt find anything that was popular. I tried "All Call Record" but its a crappy app. I could hardly hear anything and even after uninstalling the app, th voice quality was bad. Had to reboot the phone.
I need something where I can select what part of the conversation to record. Say somebody is giving directions/phone numbers. Instead of fumbling for a pen to jot it down, I can just start recording and then turn it off when required so the file size is small.
