Problem inserting rows in SQLite database

I am trying to insert rows into my database, but nothing gets persisted. Here is my helper class:

When I display it in my ListAdapter, it appears fine. As soon as I kill my application. My changes are not persisted. Why is this?

Where do you make your database? Also, you should be referencing aspects of your database with defined constants.

I don't see in your post where it is that you create your database. For example, in an app I have (link to the full file: http://code.devminded.com/score-it/src/56ac2292cfa3/src/com/devminded/scoreit/ScoreDbAdapter.java ) you can see my database class as such:

public class ScoreDbAdapter {

public static final String TAG = "com.devminded.scoreit.ScoreDbAdapter";

/**
 * Keys for the player table. ID is incrementing value to
 * reference the players.
 */
public static final String KEY_PLAYERS_ID = "_id";
public static final String KEY_PLAYERS_NAME = "name";
public static final String KEY_PLAYERS_ICON = "icon";
public static final String KEY_PLAYERS_SCORE = "score";
public static final String KEY_PLAYERS_ORDER = "turn";

/**
 * Keys for the History table.  Sequence is an increase value.  Their order
 * is the order the transactions were made.
 */
public static final String KEY_HISTORY_ID = "_id";
public static final String KEY_HISTORY_PLAYER = "player";
public static final String KEY_HISTORY_VALUE = "value";
public static final String KEY_HISTORY_NOTE = "note";

In create player you can see I am using the same functionality for adding that you are. I do not however see where you are creating the database. Can you present to us that similar functionality? Something is obviously amiss and we seem to be missing some aspect of the required information still.

Edit: Sorry, apparently my source somehow got a mixture of tabs and spaces in it, I guess I messed up an eclipse setting.
