Android :: SQLlite Crashes After Try To Retrieving Data

Jun 6, 2010

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";....................

Android :: Load Data From A URL To SQLLite?

Oct 30, 2010

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?

Android :: ListActivity - Alter Data From SQLLite Before Putting Into Row

Dec 11, 2009

@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"?

Android :: Retrieving Data From The Database

Jul 10, 2009

I created the following method for retrieving stored settings from the database:

public String getEntry(long rowIndex){
String value = "";

Cursor c = db.query(DATABASE_TABLE, new String[] {KEY_NAME, VALUE}, KEY_NAME + "=" + rowIndex, null, null, null, null);
int columnIndex = c.getColumnIndex(VALUE);
int rowsCount = c.getCount();
if(rowsCount > 0){
String value = c.getString(columnIndex);
}

return value;
}

On debugging I can see cursor c contains two columns and one row but when it comes to line

String value = c.getString(columnIndex);

it throws the CursorIndexOutOfBoundsException although columnIndex = 1 which should point to a valid entry. Does anyone know what could be wrong here?

Android :: Retrieving Data From USSD Command

May 17, 2009

I want to call a USSD (http://en.wikipedia.org/wiki/USSD) command and have the reply returned as a String. I can make the device automatically dial the USSD - like so

// String encodedHash = Uri.encode("#"); String ussd = "*" + encodedHash + "105" + encodedHash; startActivityForResult(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussd)), 1); //

This calls the USSD and the result is displayed in an alert menu generated by the OS dialer. There's no way that I can see to intercept the USSD reply, prevent the dialer displaying it, and then use the result as a String. Essentially, all I really want to do is (pseudo code) // String ussdReply = call("*#105#"); // I've tried creating an "onActivityResult" but it never receives anything from the startActivityForResult. So, does anyone know how I can use the reply within an application?

Android :: AppWidget Retrieving Data From Another Application

Apr 30, 2010

I have an AppWidget which provides a summary of some data stored and controlled by my main Application. (In a similar way to a Calendar AppWidget showing the next event from the main Calendar application). I want to know the best practice for retrieving the data to update my widget. I have followed the example, and I have extended AppWidgetProvider and have a working widget, onto which I can update. I would expect to read the data from my main application and then update it via my AppWidgetProvider's onUpdate() routine.

Now, is the best practice here for my separate main application to provide the data via a ContentProvider? I assume so, as my Appwidget is not part of the same application. Is it possible to access a ContentProvider inside my onUpdate() routine? Before writing my main application content provider I started to test out retrieving some available data like Contacts information, and showing say a contact name in my widget, to show I can extract data from an existing ContentProvider. When accessing the Contacts contentprovider, the examples talk about:

1) Activity.managedQuery(), but my AppWidget is not an activity. 2) ContentResolver.query(), but I can't work out how to get a valid ContentResolver so I can access the Contacts. getContentResolver() does not appear to be defined for AppWidgetProviders. Am I approaching this the correct way?

Android :: Error When Retrieving OData Data While Using OData4J

Nov 2, 2010

I am trying to use OData4J to retrieve a list of Users from the StackOverflow OData service (onto an Android 2.1 device), but it isn't working.

public static Enumerable<OEntity> getUserInfo() {
ODataConsumer c = ODataConsumer.create("https://odata.sqlazurelabs.com/OData.svc/v0.1/rp1uiewita/StackOverflow/");
return c.getEntities("Users").execute();

I think it is unable to retrieve data from the URL. Any ideas why this would be? Is there anything wrong with my code?

Android :: Retrieving And Parsing ICal Data Over HTTP

Jan 23, 2010

I am making an application that asks the user for userid, appends the userid to a static HTTP link to retrieve the user's daily schedule info file that has a .ical (calendar) extension. I need to read the data from file, format in new UI and representing some useful data on an Android device. My query is can I access a static HTTP link behind the scenes? And when I use the same link on desktop browser, it asks user to save the file — how can I do this on a mobile? Do I need to read the data and save it somewhere or I can save the .ical file and read from it?

General :: Retrieving Google Keep Data

Aug 20, 2013

I have the following issue; a couple of months ago i had a Desire z (happy HTC One owner now) but it fell and it broke. Or atleast the phone itself/ screen does nothing. However i can hook the phone up to my pc and its get recognized and i can browse the phone with the command prompt.

My phone broke while i was on a trip in Thailand and unfortunately the info (email adresses from new friends) that i typed into google keep that night had not been synced yet...

I would very much like to get this info off of my phone and read it or transfer it to my new phone or something (reading it on the pc has my preference as my HTC One is not rooted).

General :: Viber Crashes If Using Restored Backup Data

Jun 2, 2014

I'm on a Samsung Galaxy S2 GT-i9100 running SlimSaber 4.4.2 20140531 (Kernel 3.0.80-SlimKernel+). I backed up my APKs and Data with MyBackup Pro. Switched from NeatROM by flashing to Slim Saber. Restored all my data using MyBackup Pro. Mostly everything works except for Viber

A fresh installation of Viber works. But the moment I restore my data, it will not start up anymore. I've checked CatLog and the main error seems to be permission based:

Code:
Failed to chmod(/data/data/com.viber.voip/databases/viber_messages):
libcore.io.ErrnoException: chmod failed: EPERM (Operation not permitted)

Unable to create files directory /data/data/com.viber.voip/files

I've tried manually changing the permissions to follow the same perms from the "fresh data" of Viber - but that doesn't seem to fix this error.

Full Viber log:

06-02 15:22:57.295 I/ViberApplication(11763): ViberApplication, initialization STARTED
06-02 15:22:58.145 W/FileUtils(11763): Failed to chmod(/data/data/com.viber.voip/app_optimized): libcore.io.ErrnoException: chmod failed: ENOENT (No such file or directory)

General :: Data Usage Settings Crashes When Opened

I have a Motorola RAZR V XT885 running stock Android 4.0.4 on Virgin Mobile.

A couple days ago I tried to set a mobile data limit at 6gb using the stock app. For some reason it thought I wanted a limit set at 500gb. Since then I have not been able to reopen the app to reset it or turn off the limit, settings crashes and sends me back to my home screen. I have rebooted my phone multiple times and cleared the cache, but I'm unsure where to go from here.

Android :: Activity Crashes When Remote Service Crashes

Jul 16, 2010

I'm trying to understand remote services at the moment and everything works fine, i can start the service and know how to communicate with it through the AIDL-interface. My problem is that the service seems to still run in the same process like the activity it was started from, because the activity crashes too, if there is an error thrown in the Service.

I set the service process to remote ( android:process=":remote" ) so what am i doing wrong? Or what do i have to do to unbind the service-process completely from the activity-process?

Android :: Storing Object Into SQLlite Database

Nov 16, 2010

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.

Android :: Write Content Provider Not Backed By SQLLite?

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.

Android :: Tips - Tools For Working With SqlLite In Phone?

Nov 14, 2010

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?

Android :: Droid Sqllite Taking Long Time To Complete / Options For Moving To Start Of Result Set?

Nov 2, 2010

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.

Android :: Android SqlLite ContextWrapper.openOrCreateDatabase() Nullpointer?

Nov 18, 2010

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):

CODE:...........

Stacktrace:
