[Solved] Error message ‘java.net.SocketException: socket failed: EACCES (Permission denied)’

I get the error message

java.net.SocketException: socket failed: EACCES (Permission denied)

when I try to apply the code below. This is the function I call and gives me this 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();
}

And this is my manifest file:

<?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>

How can I fix this problem?

Solution #1:

Try with,

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

instead of,

<permission  android:name="android.permission.INTERNET"></permission>
Respondent: user370305

Solution #2:

Try this:

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

And your activity namesmust be like this with capital letters:

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

Solution #3:

try it.

<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" />
Respondent: Neeraj Singh

Solution #4:

Try moving <uses-permission> outside the <application> tag.

Respondent: Irshu

Solution #5:

Uninstalling the app on device and then reinstalling fixed it for me.

Tried all the other options, nothing. Finally found this post. This is after adding permission (below) and cleaning build.

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

Solution #6:

It can be fixed by placing the lines in the android manifest file:

<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" />

Solution #7:

Add those source code to your Java file as below:

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

Solution #8:

You may need to do AndroidStudio – Build – Clean

If you updated manifest through the filesystem or Git it won’t pick up the changes.

Respondent: David A

Solution #9:

If you are using an emulator for testing then you must use <uses-permission android:name="android.permission.INTERNET" />only and ignore <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />.It’s work for me.
