Be aware that you need to bundle an object in an Intent, that object must implement the Parcelable interface. Here's a common implementation taken from the Parcelable documentation...

public class MyParcelable implements Parcelable {
     private int mData;

     public int describeContents() {
         return 0;
     }

     public void writeToParcel(Parcel out, int flags) {
         out.writeInt(mData);
     }

     public static final Parcelable.Creator<MyParcelable> CREATOR
             = new Parcelable.Creator<MyParcelable>() {
         public MyParcelable createFromParcel(Parcel in) {
             return new MyParcelable(in);
         }

         public MyParcelable[] newArray(int size) {
             return new MyParcelable[size];
         }
     };

     private MyParcelable(Parcel in) {
         mData = in.readInt();
     }
 }

Once you've done that, simply pass the object around in an Intent...

Intent i = new Intent(getApplicationContext(), ACTIVITY_TO_START.class);
i.putExtra("extra_key", new MyParcelable());
startActivity(i);

to retrieve the object for the starting activity...

Bundle extras = getIntent().getExtras();

if(extras != null && extras.containsKey("extra_key"))
{
    MyParcelable p = (MyParecelable)extras.getParcelable("extra_key");
}

Simple solution: Use intents for this

Personal.class

public class Personal extends Activity {

    @Override 
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.personal);

        Intent i = new Intent(getApplicationContext(), Educational.class);
        i.putExtra("personal_details",<-get data from object->);
        startActivity(i);
    } 
}

Educational.class

public class Personal extends Activity {

    @Override 
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.personal);

        String personal_details; 

        Bundle extras = getIntent().getExtras();
        if (extras != null) {
        personal_details= extras.getString("personal_details");
        } 

        Intent i = new Intent(getApplicationContext(), educational.class);
        i.putExtra("personal_details",personal_details);
        i.putExtra("educational_details",<-get data from object->);
        startActivity(i);
    } 
}

Job.class

public class Personal extends Activity {

    @Override 
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.personal);

        String personal_details,educational_details; 

        Bundle extras = getIntent().getExtras();
        if (extras != null) {
        personal_details= extras.getString("personal_details");
        educational_details= extras.getString("educational_details");
        } 

        Intent i = new Intent(getApplicationContext(), FinalResult.class);
        i.putExtra("personal_details",personal_details);
        i.putExtra("educational_details",educational_details);
        i.putExtra("job_details",<-get data from object->);
        startActivity(i);
    } 
}

FinalResult.class

public class Personal extends Activity {

    @Override 
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.personal);
        String personal_details,educational_details,job_details; 

        Bundle extras = getIntent().getExtras();
        if (extras != null) {
        personal_details= extras.getString("personal_details");
        educational_details= extras.getString("educational_details");
        job_details= extras.getString("job_details");
        } 
    } 
}

{EDIT-1}

have a look at one of my answers in different storage options in android - Click Here
You can achieve it using application variable or shared preferences but i would not recommend it. !
Try storing it in POJO(Plain old Java class)

{EDIT-2}

Hmm if i understand correctly your question:: You are connected to internet(Wifi,Wired,... etc) basically you are trying to show a dialog when there is no network connectivity ! .... You can take the help of Broadcast receivers ...

Try this:: Set the broadcast receiver to fire the intent when there is no net connectivity .... Write the code to catch that intent and pop the dialog .... In this dialog give the user option to reconnect the connectivity !

thanks for your reply is any way to use global object for saving all details in one userdetails Object and update all details to that object only — , Oct 15 '14 at 07:06
