'Java.net.SocketException: yuva başarısız oldu: EACCES (İzin reddedildi)' hata mesajı

Hata mesajını alıyorum

java.net.SocketException: yuva başarısız oldu: EACCES (İzin reddedildi)

Aşağıdaki kodu uygulamaya çalıştığımda. Bu, çağırdığım işlev ve bana bu istisnayı veriyor.

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();
}

Ve bu benim manifest dosyam:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.apk"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="14" />
    <permission android:name="android.permission.INTERNET"></permission>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".PItestActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="addfriend"></activity>
        <activity android:name="updateDetails"></activity>
        <activity android:name="Details"></activity>
        <activity android:name="updateimage"></activity>
    </application>
</manifest>

Bu sorunu nasıl düzeltebilirim?

Şunu deneyin:

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

onun yerine,

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

Bunu dene:

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

Ve activity namesşununla böyle olmalısın capital letters:

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

dene.

<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" />

Etiketin <uses-permission>dışına taşınmayı deneyin <application>.

Uygulamanın cihazdan kaldırılması ve ardından yeniden yüklenmesi benim için düzeltildi.

Diğer tüm seçenekleri denedim, hiçbir şey. Sonunda bu gönderi bulundu . Bu izin eklendikten (aşağıda) ve derlemeyi temizledikten sonra.

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

Android manifest dosyasına satırları yerleştirerek düzeltilebilir:

<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" />

resim açıklamasını buraya girin

Bu kaynak kodunu Java dosyanıza aşağıdaki gibi ekleyin:

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

AndroidStudio - Build - Clean yapmanız gerekebilir

Manifest'i dosya sistemi veya Git üzerinden güncellediyseniz, değişiklikleri almayacaktır.

Test için bir emülatör kullanıyorsanız, <uses-permission android:name="android.permission.INTERNET" />sadece kullanmanız ve görmezden gelmeniz gerekir <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />.
