client.connect() funktioniert nicht

Question

Ich habe versucht, eine Android-Anwendung zu bauen. Ich versuche das "mobile_num" in der Datenbank zu speichern. Ich verwende GET-Methode, um die Daten zu senden. Client.connect() funktioniert jedoch nicht. Ich habe alles versucht, um es zu korrigieren und den Fehler zu finden, aber alle meine Versuche sind gescheitert. Ich hätte gerne Vorschläge, wie die Fehler behoben werden können.

Code:

public class Mobile_num erweitert AppCompatActivity {

/** 
* ATTENTION: This was auto-generated to implement the App Indexing API. 
* See https://g.co/AppIndexing/AndroidStudio for more information. 
*/ 
private GoogleApiClient client; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_mobile_num); 
    // ATTENTION: This was auto-generated to implement the App Indexing API. 
    // See https://g.co/AppIndexing/AndroidStudio for more information. 
    client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build(); 
} 

public void m_sign_in(View view) { 
    final EditText num = (EditText) findViewById(R.id.txt_mob); 
    try { 
     String mob_val = URLEncoder.encode(num.getText().toString(), "UTF-8"); 

     RequestParams params = new RequestParams(); 
     params.put("app", "user"); 
     params.put("method", "register"); 
     params.put("mobile_no", mob_val); 

     String tag = "play"; 
     Log.i(tag, "num :" + params); 

     new signin_process().execute(params); 
    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    } 
}

public void onStart() { 
    super.onStart(); 

    // ATTENTION: This was auto-generated to implement the App Indexing API.

    client.connect();

String url_s = "http://localhost/int/api.php";

Läuft auf Ihrem Telefon ein Server? Sie erhalten die Verbindung zurückgewiesen, da localhost Ihr Gerät ist, auf dem Sie diesen Code ausführen.
