android-value problems between the different activity

android application value share

I define a class, which defines the activity I need to pass other variables,
package com.example.moi;
import android.app.Application;
public class Declare extends Application
{
private String pwd = "";
private String shopname = "";
private String position = "";
private String shelfheap = "";
private String shelfno = "";
public void setUser (String pwd)
{
this.pwd = pwd;
}

public String getUser ()
{
return this.pwd;
}


public void setShopname (String shopname)
{
this.shopname = shopname;
}
public String getShopname ()
{
return this.shopname;
}

public void setPosition (String position)
{
this.position = position;
}
public String getPosition ()
{
return this.position;
}


public void setShelfheap (String shelfheap)
{
this.shelfheap = shelfheap;
}
public String getShelfheap ()
{
return this.shelfheap;
}


public void setShelfno (String shelfno)
{
this.shelfno = shelfno;
}
public String getShelfno ()
{
return this.shelfno;
}
}
In the first user login activity, pwd = pwdedittext.getText () toString ();.
. ((Declare) getApplication ()) setUser (pwd);
Then in the third activity, String pwd = ((Declare) getApplicationContext ()). GetUser () ;/ / user pass over the job number, job number is always the result of user pass, however, do not know why the trouble to see heroes look, thank you.
Note: Other variables in the second activity, using the same method can be passed to a third activity, is the first activity of the user job number does not reach the third activity. . Hurry!<-! Main posts under Banner (D4) -><-! Posts under the main text (D5) ->

Store user information is best not to do so.
Comes to passwords, encrypted storage is best, you can use SQLCipher, using AES encryption, but this will increase the volume apk's: Android proper use SQLCipher to encrypt the database
If no requirements for information security and want to save it with a simple point SharedPreferences or SQLite, so you can always come up with.

I do not ask for information security here is that the user wants the job number from the first activity reached the third activity, then execute insert statement, stored in sqlite database, but also expert guidance.
