cannot insert a record with a foreign key (android sqlite)

I have two tables. One with primary key and another with foreign key to the first table.


I try to add item to the first one and then an item to the second one.


my fragment code:



long phoneNewId = phoneDal.addItem(newPhone);
if ( phoneNewId != 0) {
String comment = ((EditText)rootView.findViewById(R.id.comment_text)).getText().toString();
commentDal.addItem(phoneNewId, comment);
}


PhoneDal:



public class PhoneDal extends SQLiteOpenHelper {

// Database Version
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = Constants.DB_NAME;

public static final String BLOCKED_PHONES_TABLE = "BLOCKED_PHONES_TABLE";

public PhoneDal(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {
// SQL statement to create book table

String CREATE_BLOCKED_PHONES_TABLE =
"CREATE TABLE "+ BLOCKED_PHONES_TABLE +
" ( "+ KEY_ID+" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL DEFAULT 1, "
+ KEY_PHONE+" TEXT, "
+ KEY_IS_BLOCKED+" BIT )";

db.execSQL(CREATE_BLOCKED_PHONES_TABLE);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
if (newVersion > oldVersion) {
Log.w("MyAppTag", "Updating database from version " + oldVersion
+ " to " + newVersion + " .Existing data will be lost.");
// Drop older books table if existed
db.execSQL("DROP TABLE IF EXISTS " + BLOCKED_PHONES_TABLE);

// create fresh books table
this.onCreate(db);
}

}



private static final String KEY_ID = "id";
private static final String KEY_PHONE = "KEY_PHONE";
private static final String KEY_IS_BLOCKED = "KEY_IS_BLOCKED";

public long addItem(Phone phone) {
Log.d(Constants.LOGGER_TAG, "add saved-offer");
// 1. get reference to writable DB
SQLiteDatabase db = this.getWritableDatabase();

// 2. create ContentValues to add key "column"/value
ContentValues values = new ContentValues();
//values.put(KEY_ID, phone.id);
values.put(KEY_PHONE, phone.phone);
values.put(KEY_IS_BLOCKED, phone.isBlocked);

// 3. insert
long newRowId =
db.insertWithOnConflict(BLOCKED_PHONES_TABLE, KEY_ID,
values, SQLiteDatabase.CONFLICT_REPLACE);

// 4. close
db.close();
return newRowId;
}


CommentDal:



public class CommentDal extends SQLiteOpenHelper {

// Database Version
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = Constants.DB_NAME;

private static final String COMMENTS_TABLE = "COMMENTS_TABLE";

public CommentDal(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {
// SQL statement to create book table

String CREATE_COMMENTS_TABLE =
"CREATE TABLE " + COMMENTS_TABLE +
" ( "+ KEY_ID+" INTEGER, "
+ KEY_COMMENT_TEXT+" TEXT "
+ "FOREIGN KEY("+KEY_ID+") REFERENCES "+PhoneDal.BLOCKED_PHONES_TABLE+"("+KEY_ID+"))";

db.execSQL(CREATE_COMMENTS_TABLE);

}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
if (newVersion > oldVersion) {
Log.w("MyAppTag", "Updating database from version " + oldVersion
+ " to " + newVersion + " .Existing data will be lost.");
// Drop older books table if existed
db.execSQL("DROP TABLE IF EXISTS " + COMMENTS_TABLE);

// create fresh books table
this.onCreate(db);
}
}


private static final String KEY_ID = "id";
private static final String KEY_COMMENT_TEXT = "KEY_COMMENT_TEXT";

public void addItem(long phoneID, String comment) {
Log.d(Constants.LOGGER_TAG, "add saved-offer");
// 1. get reference to writable DB
SQLiteDatabase db = this.getWritableDatabase();

// 2. create ContentValues to add key "column"/value
ContentValues values = new ContentValues();
values.put(KEY_ID, phoneID);
values.put(KEY_COMMENT_TEXT, comment);

// 3. insert
long newRowId = db.insertWithOnConflict(COMMENTS_TABLE, KEY_ID, values,
SQLiteDatabase.CONFLICT_REPLACE);

// 4. close
db.close();
}
}


but i get this error: even after re-installing my app
