Hi,
I have written the following content provider, but when I try to pull
information from it into an array, I get the following error:
12-21 15:14:18.627: ERROR/ActivityThread(1160): Failed to find
provider info for cicero.org.provider.CiceroContentProvider
I presume its something to do with my naming of the CONTENT_URI or
something? I'm not quite sure how it works so could anyone explain a
bit and spot what I have done wrong?
This is what I have in the manifest:
XML:
<provider android:name=".CiceroContentProvider"
android:authorities="cicero.org.provider.CiceroContentProvider" />
Java:
public class CiceroContentProvider extends ContentProvider{
//URI
public static final Uri CONTENT_URI =
Uri.parse("content://
cicero.org.provider.CiceroContentProvider");
//Underlying database
private SQLiteDatabase settingsDB;
private static final String TAG = "CiceroProvider";
private static final String DATABASE_NAME = "cicero_settings.db";
private static final int DATABASE_VERSION = 1;
private static final String SETTINGS_TABLE = "settings";
//Column names
public final static String _ID = "_id";
public final static String VOIPUSERNAME = "voipusername";
public final static String VOIPAUTHID = "voipauthid";
public final static String PASSWORD = "password";
public final static String SIPPROXYSERVER = "sipproxyserver";
public final static String SIPREGISTRAR = "sipregistrar";
public final static String SIPREALM = "siprealm";
public final static Integer EXPIRESTIME =30;
//column indexes
public static final int VOIPUSERNAME_COL = 1;
public static final int VOIPAUTHID_COL = 2;
public static final int PASSWORD_COL = 3;
public static final int SIPPROXYSERVER_COL = 4;
public static final int SIPREGISTRAR_COL = 5;
public static final int SIPREALM_COL = 6;
public static final int EXPIRESTIME_COL = 7;
//helper class
private static class settingsDatabaseHelper extends
SQLiteOpenHelper{
private static final String CREATE_SETTINGS_TABLE
= "CREATE TABLE tbl_settings(" +
"_ID INTEGER PRIMARY KEY AUTOINCREMENT," +
"VOIPUSERNAME TEXT," +
