Message d'erreur 'Java.net.SocketException: socket a échoué: EACCES (autorisation refusée)'

Je reçois le message d'erreur

Java.net.SocketException: échec de la socket: EACCES (autorisation refusée)

quand j'essaie d'appliquer le code ci-dessous. C'est la fonction que j'appelle et qui me donne cette exception.

public void run() {
    // TODO Auto-generated method stub
    URL myurl = null;

    try {
        myurl = new URL("http://10.0.2.2/list.JSON");
    }
    catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    try {
        URLConnection myconn = myurl.openConnection();
        InputStream in = new BufferedInputStream(myconn.getInputStream());
        InputStreamReader reader = new InputStreamReader(in);
        BufferedReader br = new BufferedReader(reader);
        String line;
        StringBuilder sb = new StringBuilder();
        while ((line=br.readLine()) != null)
        {
            sb.append(line);
            //Toast.makeText(getApplicationContext(), "I enter here", Toast.LENGTH_LONG).show();
        }
        jsoncode = sb.toString();
    }
    catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    threading = true;
    super.run();
}

Comment puis-je résoudre ce problème?

Essayez avec,

<uses-permission Android:name="Android.permission.INTERNET"/>

au lieu de,

<permission  Android:name="Android.permission.INTERNET"></permission>

Essaye ça:

<uses-permission Android:name="Android.permission.INTERNET"/>

Et votre activity namesdoit être comme ça avec capital letters:

<activity Android:name=".Addfriend"/>
    <activity Android:name=".UpdateDetails"/>
    <activity Android:name=".Details"/>
    <activity Android:name=".Updateimage"/>

l'essayer.

<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" />

Essayez de déplacer <uses-permission> en dehors de la balise <application>.

Ajoutez ce code source à votre fichier Java comme ci-dessous:

StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectDiskReads().detectDiskWrites().detectNetwork().penaltyLog().build());

Vous aurez peut-être besoin de faire Android Studio - Build - Clean

Si vous avez mis à jour manifeste via le système de fichiers ou Git, les modifications ne seront pas prises en compte.
