App gestoppt beim Aufruf von registerToken

Question

Ich versuche, einfache Anwendung (namens Noti) mit Benachrichtigungen mit Firebase-Plattform zu entwickeln. Ich muss das Token in Datenbank speichern mit PHP-Skript auf meinem Server gespeichert. Das Problem ist, ich erhalte die Nachricht Noti has stopped nach dem Drücken der Taste.

package com.example.jaroslavvystavel.noti; 

import android.content.Intent; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.widget.Button; 
import android.widget.Toast; 

import com.google.firebase.iid.FirebaseInstanceId; 

import java.io.IOException; 

import okhttp3.FormBody; 
import okhttp3.OkHttpClient; 
import okhttp3.Request; 
import okhttp3.RequestBody; 

public class MainActivity extends AppCompatActivity { 

    private static final String TAG = "MainActivity"; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     Button btnShowToken = (Button)findViewById(R.id.button_show_token); 
     btnShowToken.setOnClickListener(new View.OnClickListener() { 
      @Override 

      public void onClick(View v) { 
       //Get the token 
       String token = FirebaseInstanceId.getInstance().getToken(); 
       Log.d(TAG, "Token: " + token); 
       Toast.makeText(MainActivity.this, token, Toast.LENGTH_SHORT).show(); 
       registerToken(token); 

      } 

     }); 

    } 
    private void registerToken(String token) { 

     OkHttpClient client = new OkHttpClient(); 
     RequestBody body = new FormBody.Builder() 
       .add("Token",token) 
       .build(); 

     Request request = new Request.Builder() 
       .url("http://www.stud.fit.vutbr.cz/~xvose02/testuji.php") 
       .post(body) 
       .build(); 

     try { 
      client.newCall(request).execute(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
} 

Ich wurde von diesem Youtube tutorial inspiriert, wo alles gut funktioniert. Ich habe nur den Code des Autors leicht geändert, um die Methode registerToken jedes Mal aufzurufen, wenn der Benutzer die Taste drückt.

Nicht sicher Parameter der Methode ...

Answer 1

ein Hinzufügen Antwort zum Beispielcode

Die Anfrage sieht gut aus. Die anderen Parameter sind jedoch nicht wirklich notwendig. Unten ist, wie ich denke, der Code sollte (vereinfacht) sein.

private void registerToken(final String token) { 

     new updateDb().execute(token); 

    } 

    private class updateDb extends AsyncTask<String, Void, Void> { 

     @Override 
     protected Void doInBackground(String... token) { 
      try { 
       OkHttpClient client = new OkHttpClient(); 
       RequestBody body = new FormBody.Builder() 
         .add("Token", token[0]) 
         .build(); 

       Request request = new Request.Builder() 
         .url("http://www.stud.fit.vutbr.cz/~xvose02/testuji.php") 
         .post(body) 
         .build(); 

       client.newCall(request).execute(); 

      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
      return null; 
     } 
    }
