[Amin-rz]

سلام دوستان من هر کاری کردم نتونستم یه وی پی ان بسازم.
این کلاس وی پی ان :

package com.kpbird.globaltouchevent;

import java.io.FileInputStream;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.nio.ByteBuffer;
import java.util.Enumeration;

import android.content.Intent;
import android.net.VpnService;
import android.os.Handler;
import android.os.Message;
import android.os.ParcelFileDescriptor;
import android.util.Log;
import android.widget.Toast;

public class ToyVpnService extends VpnService implements Handler.Callback, Runnable {
private static final String TAG = "ToyVpnService";

private Handler mHandler;
private Thread mThread;

private ParcelFileDescriptor mInterface;

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// The handler is only used to show messages.
if (mHandler == null) {
mHandler = new Handler(this);
}

// Stop the previous session by interrupting the thread.
if (mThread != null) {
mThread.interrupt();
}

// Start a new session by creating a new thread.
mThread = new Thread(this, "ToyVpnThread");
mThread.start();
return START_STICKY;
}

@Override
public void onDestroy() {
if (mThread != null) {
mThread.interrupt();
}
}

public boolean handleMessage(Message message) {
if (message != null) {
Toast.makeText(this, message.what, Toast.LENGTH_SHORT).show();
}
return true;
}

@Override
public synchronized void run() {
Log.i(TAG,"running vpnService");
try {
runVpnConnection();
} catch (Exception e) {
e.printStackTrace();
//Log.e(TAG, "Got " + e.toString());
} finally {
try {
mInterface.close();
} catch (Exception e) {
// ignore
}
mInterface = null;

mHandler.sendEmptyMessage(R.string.disconnected);
Log.i(TAG, "Exiting");
}
}

private boolean runVpnConnection() throws Exception {

configure();

FileInputStream in = new FileInputStream(mInterface.getFileDescriptor());

// Allocate the buffer for a single packet.
ByteBuffer packet = ByteBuffer.allocate(32767);

// We keep forwarding packets till something goes wrong.
while (true) {
// Assume that we did not make any progress in this iteration.
boolean idle = true;

// Read the outgoing packet from the input stream.
int length = in.read(packet.array());
if (length > 0) {

Log.i(TAG,"************new packet");
System.exit(-1);
while (packet.hasRemaining()) {
Log.i(TAG,""+packet.get());
//System.out.print((char) packet.get());
}
packet.limit(length);
// tunnel.write(packet);
packet.clear();

// There might be more outgoing packets.
idle = false;
}
Thread.sleep(50);
}
}

public String getLocalIpAddress()
{
try {
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
Log.i(TAG,"****** INET ADDRESS ******");
Log.i(TAG,"address: "+inetAddress.getHostAddress());
Log.i(TAG,"hostname: "+inetAddress.getHostName());
Log.i(TAG,"address.toString(): "+inetAddress.getHostAddress().toString());
if (!inetAddress.isLoopbackAddress()) {
//IPAddresses.setText(inetAddress.getHostAddress().t oString());
Log.i(TAG,"IS NOT LOOPBACK ADDRESS: "+inetAddress.getHostAddress().toString());
return inetAddress.getHostAddress().toString();
} else{
Log.i(TAG,"It is a loopback address");
}
}
}
} catch (SocketException ex) {
String LOG_TAG = null;
Log.e(LOG_TAG, ex.toString());
}

return null;
}

private void configure() throws Exception {
// If the old interface has exactly the same parameters, use it!
if (mInterface != null) {
Log.i(TAG, "Using the previous interface");
return;
}

// Configure a builder while parsing the parameters.
Builder builder = new Builder();
builder.setMtu(1500);
builder.addAddress("10.0.2.0", 24);
builder.addRoute("0.0.0.0",0);

try {
mInterface.close();
} catch (Exception e) {
// ignore
}

mInterface = builder.establish();
}
}




با این کد هم شروعش می کنم :

Intent ToyVpnService = new Intent(this,ToyVpnService.class);
startService(ToyVpnService);



اینم مانیفست :

خطا میده؟ در چه مرحله ای خطا میده؟ لاگ خطاها را میذاشتید تا شاید دوستان بهتر بتونن کمک کنند!

داخل کد لاگهای زیادی گذاشته شده است وضعیت این لاگها چیست؟
