Question

Recibo el mensaje de error

java.net.SocketException: socket failed: EACCES (Permiso denegado)

cuando trato de aplicar el código a continuación. Esta es la función que llamo y me da esta excepción.

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();
}

Y este es mi archivo manifiesto:

<?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>

¿Como puedo solucionar este problema?

Answer 1

Agregue esos códigos fuente a su archivo Java de la siguiente manera:

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

Answer 2

Es posible que necesites hacer AndroidStudio - Build - Clean

Si actualizó el manifiesto a través del sistema de archivos o Git, no recogerá los cambios.

Answer 3

Intente mover <uses-permission> fuera de la etiqueta <application> .

Answer 4

Prueba con,

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

en lugar de,

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

Answer 5

Prueba esto:

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

Y sus activity names deben ser así con capital letters :

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

Answer 6

intentalo.

<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" />
