데이터베이스 생성 안드로이드/안드로이드 스튜디오

Question

그냥 안드로이드 시작하고 간단한 데이터베이스를 만들려고 작동하지 않습니다.

FoodMacrosTable.java 
public class FoodMacrosTable { 

public static final String DB_NAME = "FoodDatabase.db"; 
public static final int DB_VERSION = 1; 

public class FoodMacros implements BaseColumns { 

    public static final String TABLE_NAME = "FoodMacros"; 


    public static final String FOOD_NAME = "Food name"; 
    public static final String FOOD_PROTEIN = "Amount of protein in 100g"; 
    public static final String FOOD_CARBS = "Amount of carbs in 100g"; 
    public static final String FOOD_FATS = "Amount of fats in 100g"; 
    public static final String FOOD_CALORIES = "Amount of calories in 100g"; 
    public static final String FOOD_VIT_A = "% of daily needs in 100g"; 

    public final String[] TABLE_COLUMNS = {FOOD_NAME,FOOD_PROTEIN,FOOD_CARBS,FOOD_FATS,FOOD_CALORIES, 
      FOOD_VIT_A}; 

} 

}

HealthyDbHanbler.java 

public class HealthyDbHandler extends SQLiteOpenHelper { 

public HealthyDbHandler(Context context){ 
    super(context,FoodMacrosTable.DB_NAME,null,FoodMacrosTable.DB_VERSION); 
} 

@Override 
public void onCreate(SQLiteDatabase sqLiteDatabase) { 
    String createTable = "CREATE TABLE " + FoodMacrosTable.FoodMacros.TABLE_NAME + " (" + 
      FoodMacrosTable.FoodMacros._ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + 
      FoodMacrosTable.FoodMacros.FOOD_NAME + " TEXT NOT NULL, " + 
      FoodMacrosTable.FoodMacros.FOOD_PROTEIN + " TEXT NOT NULL, " + 
      FoodMacrosTable.FoodMacros.FOOD_CARBS + " TEXT NOT NULL, " + 
      FoodMacrosTable.FoodMacros.FOOD_FATS + " TEXT NOT NULL, " + 
      FoodMacrosTable.FoodMacros.FOOD_CALORIES + " TEXT NOT NULL, " + 
      FoodMacrosTable.FoodMacros.FOOD_VIT_A + " TEXT NOT NULL);"; 

    sqLiteDatabase.execSQL(createTable); 


} 

@Override 
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) { 
    sqLiteDatabase.execSQL("DROP TABLE IF EXISTS " + FoodMacrosTable.FoodMacros.TABLE_NAME); 
    onCreate(sqLiteDatabase); 
} 

public void addFood(Food food){ 
    SQLiteDatabase db = this.getWritableDatabase(); 

    ContentValues values = new ContentValues(); 
    values.put(FoodMacrosTable.FoodMacros.FOOD_NAME,food.getFOOD_NAME()); 
    values.put(FoodMacrosTable.FoodMacros.FOOD_PROTEIN,food.getFOOD_PROTEIN()); 
    values.put(FoodMacrosTable.FoodMacros.FOOD_CARBS,food.getFOOD_CARBS()); 
    values.put(FoodMacrosTable.FoodMacros.FOOD_FATS,food.getFOOD_FATS()); 
    values.put(FoodMacrosTable.FoodMacros.FOOD_CALORIES,food.getFOOD_CALORIES()); 
    values.put(FoodMacrosTable.FoodMacros.FOOD_VIT_A,food.getFOOD_VIT_A()); 

    db.insert(FoodMacrosTable.FoodMacros.TABLE_NAME,null,values); 

    db.close(); 
} 

}

MainActivity.java 
public class MainActivity extends AppCompatActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    HealthyDbHandler db = new HealthyDbHandler(this) ; 
    Log.v("DBINFO","Database created"); 

}

Answer 1

sqlite 또는 응용 프로그램이 아닙니다. (아무것도 할 수없는 경우)

봅니다 Eclipse DDMS error "Can't bind to local 8600 for debugger"
