Where can find Sqlite database?

I want look for my database in my mobile (HTC M7)

Actually when I use sony mobile I can find it

But now I can't find it since I change HTC M7

This is my data path set up

And where can find it in HTC M7 ?

       public static final String TABLE_NAME = "Gsensor";  //sqlite table name
       public static final String X = "X";
       public static final String Y = "Y";
       public static final String Z = "Z";
       private final static String DATABASE_NAME = "Gsensor.db";  //database name
       private final static int DATABASE_VERSION = 1;  //db ver
       private File path = new File( Environment.getExternalStorageDirectory().getAbsolutePath() + 
                            File.separator); //db path
       String filepath = Environment.getExternalStorageDirectory().getAbsolutePath() + 
                            File.separator + "Gsensor.db";
       private File f = new File(filepath);

       //DB table
       String CreateTable = "CREATE TABLE " + TABLE_NAME + " (" +_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + 
                            X + " CHAR, " + Y + " CHAR, " + Z + " CHAR);";
       //del table
       String DelTable = "DROP TABLE IF EXISTS " + TABLE_NAME;
       public DBHelper(Context context) {
           super(context, DATABASE_NAME, null, DATABASE_VERSION);
           this.context = context;//openOrCreateDatabase is this method
                                  //so need to init context and return to
      }

       @Override
       //create table
       public void onCreate(SQLiteDatabase db) {
        SQLiteDatabase dbwrite= context.openOrCreateDatabase("f", context.MODE_WORLD_WRITEABLE, null);
        db.execSQL(CreateTable);
      }
       @Override
       //del table
       public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
         db.execSQL(DelTable);
         onCreate(db);

      }
}
