SQLiteDatabase.insert() and SQLiteDatabase.execSQL("insert into ...") doesn't work

Question

I'm working on an Android application in Java. In my application I need, among other things, to store an address in a database. My address is stored in a table named "adresse". This table is defined as below:

CREATE TABLE "adresse" (
    "numero_rue"  TEXT,
    "type_voie"   TEXT,
    "voie"        TEXT,
    "code_postal" TEXT,
    "ville"       TEXT
);

I've tried to insert an address in my table by two different methods:

public void setAdresse(String numRue, String typeVoie, String voie, String codePostal, String ville) {
    // First one
    ContentValues values = new ContentValues();

    values.put("numero_rue" , numRue    );
    values.put("type_voie"  , typeVoie  );
    values.put("voie"       , voie      );
    values.put("code_postal", codePostal);
    values.put("ville"      , ville     );

    db.insert("adresse", null, values);

    // Second one
    String req = "insert into adresse (numero_rue, type_voie, voie, code_postal, ville) values";
    req += "(\"" + numRue + "\",\"" + typeVoie + "\",\"" + voie + "\",\"" + codePostal + "\",\"" + ville + "\")";

    db.execSQL(req);
}

I call the setAdresse(...) method in this method:

public void valider(View paramView) {
    [ data recovery without problems ]

    final DatabaseAccess db = DatabaseAccess.getInstance(this.getApplicationContext());
    db.open();

    db.setAdresse(numRue, typeVoie, voie, codePostal, ville);

    db.close();
}

I show you my constructor, my open(), close() and getInstance() methods:

private DatabaseAccess(Context context) { this.openHelper = new DatabaseOpenHelper(context); }

public static DatabaseAccess getInstance(Context context) {
    if( instance == null ) instance = new DatabaseAccess(context);

    return instance;
}

public void open() { this.db = openHelper.getWritableDatabase(); }

public void close() { if( this.db != null ) this.db.close(); }

My problem is that inserting the data into the table is not working. I don't find errors in the logs and my application does not crash. I don't think it is a code error and someone told me it could be linked to my "driver utilisation".
