Próbuję stworzyć 2 tabele w bazie danych, ale otrzymuję kolejne błędy sintax:

Wydaje się, że pierwszy błąd znajduje się w następnej linii kodu:
String CREATE_ACTIVITIES_DETAILS_TABLE = "CREATE TABLE " +
TABLE_ACTIVITIES_DETAILS + "(" +
ACTIVITY_ID + " INTEGER FOREIGN KEY REFERENCES " +
TABLE_ACTIVITIES + "(" + KEY_ID + "), " +
KEY_HEARTRATE + " INTEGER, "+
KEY_HEARTBEATNO + " INTEGER, "+
KEY_DISTANCE + " INTEGER, " +
KEY_SPEED + " INTEGER, " +
KEY_STRIDES + " INTEGER," +
KEY_CURRENTDATETIME + " TEXT" +
")";
db.execSQL(CREATE_ACTIVITIES_DETAILS_TABLE);
Oto moja klasa DatabaseHandler:
public class DatabaseHandler extends SQLiteOpenHelper {
// All Static variables

private static final int DATABASE_VERSION = 2;
// Database Name
private static final String DATABASE_NAME = "YastDB.com.yast.db";

private static final String TABLE_ACTIVITIES_DETAILS = "ActivitiesDetails";
// Activities Table Col names
private static final String KEY_ID = "id";

db.execSQL(CREATE_ACTIVITIES_DETAILS_TABLE);
}
// Upgrading database
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// Drop older table if existed
db.execSQL("DROP TABLE IF EXISTS " + TABLE_ACTIVITIES);
db.execSQL("DROP TABLE IF EXISTS " + TABLE_ACTIVITIES_DETAILS);
// Create tables again
onCreate(db);
}
}
Atrybuty i konstruktory ActivityEntity znajdują się poniżej. Zawiera metody ustawiania / pobierania wszystkich atrybutów
public class ActivityEntity {
//private variables
private int id;
private int activityType;
private String startDateTime;
private String endDateTime;
// Empty constructor
public ActivityEntity(){
}
// constructor
public ActivityEntity(int id, int activityType, String startDateTime, String endDateTime){

this.endDateTime = endDateTime;
}
public ActivityEntity(int activityType, String startDateTime, String endDateTime){
this.activityType = activityType;
this.startDateTime = startDateTime;
this.endDateTime = endDateTime;
}
Atrybuty i konstruktory ActivityDetails znajdują się poniżej. Zawiera metody ustawiania / pobierania wszystkich atrybutów
public class ActivityDetalis {

this.heartBeatNo = heartBeatNo;
this.distance = distance;
this.speed = speed;
this.strides = strides;
this.currentDateTime = currentDateTime;
}
Odpowiedzi:
2 dla odpowiedzi № 1Masz spację w nazwie tabeli. Usuń spację lub umieść nazwę tabeli w podwójnych cudzysłowach:
private static final String TABLE_ACTIVITIES_DETAILS = "ActivitiesDetails";
lub
private static final String TABLE_ACTIVITIES_DETAILS = ""Activities Details"";
