want to delete database file in my app. .tried with a program, that did not work - android-sqlite

Question

I am trying to delete database table either programmatically or manually.
I created my own app which is under development.
My app is named SWULJ CT Conductor
But I do not find it under android/data/data folder with any com.xxx.xxx name format
code:
public class DatabaseHelper extends SQLiteOpenHelper {
public static final String DATABASE_NAME = "BusDetails.db";
public static final String TABLE_NAME = "bus_details_table";
public static final String COL_1 = "ID";
public static final String COL_2 = "NUMBER";
public static final String COL_3 = "ROUTE";
public static final String COL_4 = "CITY";
public static final String COL_5 = "STATUS";
public DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, 1);
}
#Override
public void onCreate(SQLiteDatabase db) {
String myPath = TABLE_NAME + DATABASE_NAME;
SQLiteDatabase.deleteDatabase(new File(myPath));
db.execSQL("create table " + TABLE_NAME +" (ID INTEGER PRIMARY KEY AUTOINCREMENT,NUMBER TEXT,ROUTE TEXT,CITY TEXT,STATUS INTEGER)");
}
It is the partial code for the databasehelper class
It is called from Activity like this:
public class GenerateQrCodeActivity extends AppCompatActivity {
ImageButton imgButtonGenerateBulk;
ImageButton imgButtonGenerateSingle;
DatabaseHelper myDb;
EditText edit;
boolean flag = false;
String data_bus_number=null;
int ID_bus_number = -1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_generate_qr_code);
myDb = new DatabaseHelper(this);
imgButtonGenerateBulk =(ImageButton)findViewById(R.id.imageButtonGenerateBulk);
imgButtonGenerateSingle =(ImageButton)findViewById(R.id.imageButtonGenerateSingle);
edit = (EditText) findViewById(R.id.bus_number);
.....
.....
I placed lines
String myPath = TABLE_NAME + DATABASE_NAME;
SQLiteDatabase.deleteDatabase(new File(myPath));
But the old data from the database shows up. It is not deleted. Why? how to fix?

Answer 1

done using the function->
public void deleteDatabase() {
// Are you sure? (y/n)
final SQLiteDatabase db = this.getWritableDatabase();
final File dbFile = new File(db.getPath());
db.close();
Toast.makeText(cntxt, "db deleted", Toast.LENGTH_SHORT).show();
edit.setText("db deleted");
if (dbFile.exists()) {
SQLiteDatabase.deleteDatabase(dbFile);
}
//mOpenHelper = new DatabaseHelper(getContext());
}
