[Q] Socket code throws NullPointerException in OnsensorChanged

Hi frends im working on my android final year project based on sockets..im using ssynctask to connect socket etc..Everything works fine, since I'm using AsyncTask to create a Socket connection ... the socket works fine in the doInBackground() method, but when I try to send Sensor data from theonSensorChanged() method, I get null pointer exception. I don't know what went wrong. in short Socket returns NULL outside asyncTask Class...can some 1 help me ?..

you have to set the variable in onpostexecute() and also use
Code:
new MyTask().execute().get()
so you make sure the async task has finished for sure

Can u gv example ?

frend can u give me an example ?

forget the execute().get() for now, maybe it is not needed
read the documents for asynctask and change your result type from void, to whatever you want to set
for example if you want only the PrintWriter to be set you can do this
Code:
package com.example.sensorsmart;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStreamReader;

import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity implements SensorEventListener{
private static final int SERVERPORT = 8222;
private static final String SERVER_IP = "192.168.0.101";
private SensorManager mSensorManager;
private Sensor mAccelerometer;
private TextView tv ;
public ServerSocket serverSocket=null;
public Socket socket = null;
public BufferedReader in ;
public BufferedWriter out;
public PrintWriter pw ;
public FileWriter writer=null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new MyTask().execute();
mSensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
mAccelerometer mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
mSensorManager.registerListener(this, mAccelerometer,SensorManager.SENSOR_DELAY_NORMAL);
}
public void onStopClick(View view) {
mSensorManager.unregisterListener(this);}
private class MyTask extends AsyncTask<Void, Void, PrintWriter>
{
@Override
protected PrintWriter doInBackground(Void... arg0) {
try {
serverSocket = new ServerSocket(8222);
} catch (IOException e) {
e.printStackTrace();
}
try {
socket=serverSocket.accept();
Log.i("TcpServer", "CONNECTED");
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
pw = new PrintWriter(socket.getOutputStream(),true);
if(!in.ready())
{
Log.i("TcpServer", "READER IS NOT READY");
}
final String g;
final String c;
String b = null;
Log.i("TcpServer", "GOING");
g=in.readLine();
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(),g, Toast.LENGTH_LONG).show();
}
});
} catch (IOException e) {
e.printStackTrace();
String response = e.getCause().toString();
Log.i("TCP",response);
}
return pw;
}
protected void onPostExecute(PrintWriter result) {
pw = result;
}
}
@Override
public void onSensorChanged(SensorEvent event) {
float x = event.values[0];
float y = event.values[1];
float z = event.values[2];
if(pw!=null) pw.write("g"); //NULL POINT EXCEPTION THROWS HERE
}
}
if you want other variables to be returned too, you can make a custom object as the type of the result

is it possible to pass socket instead mof printwriter?
hi friend thank u for ur reply...is it possible to pass socket in onpostexecute () ?
i tried with below code still socket is null in ONsensor Changed
Code:
private class MyTask extends AsyncTask<Void, Void,Socket>
{
@Override
protected Socket doInBackground(Void... arg0) {
// TODO Auto-generated method stub
try {
serverSocket = new ServerSocket(8222);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
socket=serverSocket.accept();
Log.i("TcpServer", "CONNECTED");
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
pw = new PrintWriter(socket.getOutputStream(),true);
//out = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
if(!in.ready())
{
Log.i("TcpServer", "READER IS NOT READY");
}
final String g;
final String c;
String b = null;
Log.i("TcpServer", "GOING");
g=in.readLine();
//Log.i("TcpServer", in.readLine());
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(),g, Toast.LENGTH_LONG).show();
}
});
Log.i("TcpServer", "RECEIVED");
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(),g, Toast.LENGTH_LONG).show();
}
});
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
String response = e.getCause().toString();
Log.i("TCP",response);
}
return socket;
}
protected void onPostExecute(Socket result) {
socket = result;
}

yes, you can pass the socket like you do
but in the onsensorchanged function you are using the printwriter (pw) you created in the doinbackground function which is null because you haven't passed it to the main thread
so, you either have to make a new object that will pass all the things to the main threat (socket, printwriter, bufferedreader) if you want them all, or pass the printwriter only, or you will initialize them on the post execute function
for example, you can return the socket and then do
Code:
protected void onPostExecute(Socket result) {
socket = result;
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
pw = new PrintWriter(socket.getOutputStream(),true);
}

still null
here is my entire code..i have done exactly what u said...still socket null in OnsensorChanged()

this.so = s;

}
}
try this
since you are initializing in and pw inside the doinbackground, you have to pass them to the main thread
so i added another class to hold all these and i pass them on result
finally you also have to check in the onsensorchanged if the pw is null because the asynctask may have not finished yet when this is called

null
async task not completed because of socket not closed?

Thank u
bro..some how i managed to get it work..thanks a lot for ur time..and nice to meet u..

Face Detection in Background Service

I am making an android app which requires to capture image using front camera using android service. Also we need to detect face in the image so obtained. But when calling the detectfaces() function, the app unfortuantely stops. I am posting the code for it here. Please help me find out where i am going wrong.
here is my code..!!!!

Load Image from RSS Enclosure tag???

Hello everyone.
I am trying to load the Images in an listview that the RSS provides me.
http://www.nutech.nl/rss is the rss i use.
i want to load the image in listview from these tags
<enclosure> </enclosure (

is there someone who could help me ?
thank you

After few months i still havent found a solution or idea.
anyone here has ?

Use a RSS parsing library
Use my AndroidWithoutStupid Java library. It is on GitHub. There is also an article about the usage on CodeProject.
Enclosure tag is usually used for mp3 files but it doesn't matter.
After getting the enclosure value using the MvNewsFeed class, you need to download it. Use MvAsyncDownload for that. Then, use BitmapFactory.decodeFile() or a similar method to display the image in an ImageView.
