Inserting a row with Android Content Provider

I have the next Content Provider
To insert a row in Table AGENDA, I do:

ContentValues values = new ContentValues(1);
values.put("MSG", "test");
context.getContentResolver().insert(DataProvider.CONTENT_URI_AGENDA, values);


and all works well.

But now, I´d like to use the uri with AGENDA_INSERTWITHCONFLICT to insert a row.
Please, How can I modify the line :

context.getContentResolver().insert(DataProvider.CONTENT_URI_AGENDA, values);


to do it?

Here is my Provider:

public class DataProvider extends ContentProvider {
public static final String TAGPROVIDER = "net.techabout.medappointment.provider";
public static final Uri CONTENT_URI_AGENDA = Uri.parse("content://"+TAGPROVIDER+"/agenda");

public static final String TABLE_AGENDA = "agenda";

private DbHelper dbHelper;

private static final int AGENDA_ALLROWS = 5;
private static final int AGENDA_INSERTWITHCONFLICT=7;

private static final UriMatcher uriMatcher;

static {
uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
uriMatcher.addURI(TAGPROVIDER, "agenda", AGENDA_ALLROWS);
uriMatcher.addURI(TAGPROVIDER, "agenda", AGENDA_INSERTWITHCONFLICT);
}

@Override
public Uri insert(Uri uri, ContentValues values) {
SQLiteDatabase db = dbHelper.getWritableDatabase();

long id;
switch (uriMatcher.match(uri)) {
case AGENDA_ALLROWS:
id = db.insertOrThrow(TABLE_AGENDA, null, values);
break;
case AGENDA_INSERTWITHCONFLICT:
id=db.insertWithOnConflict(TABLE_AGENDA, BaseColumns._ID, values, SQLiteDatabase.CONFLICT_REPLACE);
break;

default:
throw new IllegalArgumentException("Unsupported URI: " + uri);
}

Uri insertUri = ContentUris.withAppendedId(uri, id);
getContext().getContentResolver().notifyChange(insertUri, null);
return insertUri;
}

}

Answer

make following changes, Please use naming convetions as required.

// content provider
static {
    uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
    uriMatcher.addURI(TAGPROVIDER, "agenda", AGENDA_ALLROWS);
    uriMatcher.addURI(TAGPROVIDER, "agenda_insert_conflicts", AGENDA_INSERTWITHCONFLICT);
}

calling mechanism

 String URL = "net.techabout.medappointment.provider/agenda_insert_conflicts";

  Uri students = Uri.parse(URL);
context.getContentResolver().insert(DataProvider.CONTENT_URI_AGENDA, values);
