java.net.SocketException: Socket fehlgeschlagen: EACCES (Berechtigung verweigert)

Question

Ich habe alle Lösungen durchsucht und in mein Projekt übernommen. Aber sie arbeiten nicht. Ich habe diese Berechtigung verweigert. Ich habe alle diese möglichen Berechtigungen in die Manifestdatei eingetragen. Bitte sagen Sie mir, was mit meinem Projekt nicht stimmt.

public static void getGetResponse() { 
     InputStream inputStream = null; 
     try { 
      URL url = new URL("http://120.26.89.113:8080/common/qiniuToken"); 
      HttpURLConnection connection = (HttpURLConnection)url.openConnection(); 
      connection.setRequestMethod("GET");   
      String userPassword = "wehelper:***********"; 
      byte[] encodedBytes = Base64.encode(userPassword.getBytes(), 0); 
      connection.setRequestProperty("Authorization", "Basic " + encodedBytes); 
      connection.connect(); 
      int resCode = connection.getResponseCode(); 
      if (resCode == 200) { 
       inputStream = connection.getInputStream(); 
      } 

      BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream)); 
      StringBuilder out = new StringBuilder(); 
      String line; 
      while ((line = reader.readLine()) != null) { 
       out.append(line); 
      } 
      System.out.println(out.toString());//Prints the string content read from input stream 
      Log.d("myApp",out.toString()); 
      reader.close(); 

     } catch (MalformedURLException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 

und meine manifest.xml

<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:supportsRtl="true" 
    android:theme="@style/MyMaterialTheme"> 
    <uses-permission android:name="android.permission.INTERNET"/> 
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 
    <activity android:name=".MainActivity"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application>

Ihre <uses-permission> Elemente sind an der falschen Stelle. Sie brauchen außerhalb das <application> Element, als unmittelbare Kinder des Wurzel <manifest> Element sein:

<uses-permission android:name="android.permission.INTERNET"/> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 

<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:supportsRtl="true" 
    android:theme="@style/MyMaterialTheme"> 
    <activity android:name=".MainActivity"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application>
