I design this logo by canva.
I decided to use red and green, the red color naturally gives users pause due to its connotations. Green, on the other hand, symbolizes growth, safety, a success state and generally a positive outcome..
Then I used this site to find color pattern: https://pigment.shapefactory.co/
MVC is used in this app,
And this is my directory.
This is ER diagram of the project.
To store data, I used SQLite.
As Field, I prepared 4 field: "id", "food_Name", "food_quantity", "expiry_date", "user_id".
This is the database structure.
public void onCreate(SQLiteDatabase db) {
String query =
"CREATE TABLE " + TABLE_NAME + " ( " +
COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
COLUMN_NAME + " TEXT, " +
COLUMN_QUANTITY + " REAL, " +
COLUMN_EXPIRY_DATE + " TEXT, user_id INTEGER); ";
db.execSQL(query);
}
