Question

I created a database called “enigmeDB” and a table “table_enigme”:

public class EnigmeDatabase extends SQLiteOpenHelper {
    private static final int DATABASE_VERSION = 1;
    private static final String DATABASE_NAME = "enigmeBD";
    private static final String TABLE_ENIGME = "table_enigme";

    // fields 
    private static final String KEY_ID = "id";
    private static final String KEY_DESCRIPTION = "description";
    private static final String KEY_REPONSE="reponse";
    private static final String KEY_CATEGORIE="categorie";      

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

    // creation of the table
    @Override
    public void onCreate(SQLiteDatabase db) {
        String CREATE_ENIGME_TABLE = 
            "CREATE TABLE " + TABLE_ENIGME
            + "("
            + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," 
            + KEY_DESCRIPTION + " TEXT,"
            + KEY_REPONSE + " TEXT,"
            + KEY_CATEGORIE + "TEXT"
            + ")";
        db.execSQL(CREATE_ENIGME_TABLE);    
    }

    // Update
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_ENIGME);
                onCreate(db);
    }....

When I open my DDMS perspective and open the file explorer: /data/data/com.android.enigme (my package) I find “enigmeDB” but I don’t find “table_enigme”.

Although in Sqlite database browser my table looks empty:

I insert data from an Activity , here is my class :

public class EnigmeActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    //recuperation des champs depuis main.xml
    final EditText description=(EditText) this.findViewById(R.id.description);
    final EditText reponse=(EditText)this.findViewById(R.id.reponse);
    final EditText categorie=(EditText)this.findViewById(R.id.categorie);
    Button ajouter = (Button)this.findViewById(R.id.ajouter);


   final EnigmeDatabase db=new EnigmeDatabase(this);


    ajouter.setOnClickListener(new OnClickListener() {


        public void onClick(View v) {
            Log.d("Etape : " , "Recuperation");
            Log.i("description : ", description.getText().toString());
            Log.i("reponse : ", reponse.getText().toString());
            Log.i("categorie : ", categorie.getText().toString());
            //add a new Enigme
            Log.d("Etape : ","Insertion" );
            db.ajouterEnigme(new EnigmeBean(description.getText().toString(),reponse.getText().toString(),categorie.getText().toString()));      
            Toast.makeText(EnigmeActivity.this, "Ajout avec succes!", Toast.LENGTH_SHORT).show();

        }

        });


}

That is a database file which holds all the tables.

You have opened it as in your last picture, and the column names exist as you created them.

The reason it is “empty” is because there is no data in it.

You need to populate your table with data.
