sockets - RethinkDB Connection timed out issue for Android App

Question

I want to make an android application using RethinkDB locally. However, while connecting to the database, I encounter a problem as follows. What am I doing wrong?

MainActivity.kt:

class MainActivity : AppCompatActivity() {

    private val r = RethinkDB.r

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val conn: Connection = r.connection().connect()
        r.db("test").tableCreate("tv_shows").run(conn)
        r.table("tv_shows").insert(r.hashMap("name", "Star Trek TNG")).run(conn)
        conn.close()

    }
}
