I have a problem with my database in Android app. Here’s some code:

private static final String QUESTIONS_TABLE = "questions";
/* questions keys */
public static final String KEY_ROWID = "_id";
public static final String KEY_TYPE = "type";
public static final String KEY_CONTENT = "content";
public static final String KEY_A = "answerA";
public static final String KEY_B = "answerB";
public static final String KEY_C = "answerC";
public static final String KEY_D = "answerD";

private static final String QUESTIONS_TABLE_CREATE = 
    "create table "+ QUESTIONS_TABLE +" (" + KEY_ROWID + " integer primary key autoincrement, "
    + KEY_TYPE + "integer not null,"
    + KEY_CONTENT + " text not null, "
    + KEY_A + " text, "
    + KEY_B + "text, "
    + KEY_C + "text, "
    + KEY_D + "text); ";

//--- QUESTIONS SECTION ---
//--- inserts a close question ---
public long insertCloseQuestion(int type, String content, String[] answers) {
    ContentValues initValues = new ContentValues();
    initValues.put(KEY_TYPE, type);
    initValues.put(KEY_CONTENT, content);
    if(answers != null && answers.length > 0) {
        initValues.put(KEY_A, answers[0]);
        initValues.put(KEY_B, answers[1]);
        initValues.put(KEY_C, answers[2]);
        initValues.put(KEY_D, answers[3]);
    }
    Log.d("VM", initValues.toString());

    return db.insertOrThrow(QUESTIONS_TABLE, null, initValues);
}

When I call insertCloseQuestion method, Android returns an Exception:

android.database.sqlite.SQLiteException: table questions has no column named answerD: , while compiling: INSERT INTO questions(answerD, content, answerB, answerC, type, answerA) VALUES(?, ?, ?, ?, ?, ?);

Do you have any ideas how to fix it? I know there are is a couple of topics like this, but none of the solutions help me.

    private static final String QUESTIONS_TABLE_CREATE = 
    "create table "+ QUESTIONS_TABLE +" (" + KEY_ROWID + " integer primary key autoincrement, "
    + KEY_TYPE + "integer not null,"
    + KEY_CONTENT + " text not null, "
    + KEY_A + " text, "
    + KEY_B + "text, "
    + KEY_C + "text, "
    + KEY_D + "text); ";

    I guess there are no spaces between column name and it’s type. KEY_B + "text, " put a space before text (here and with other columns).

    And do not forget to delete database after that (uninstall application from the phone)!
