Android / Java - Removing Sequential Loading Animation Delay

I have an android Animation which loads a series of sequential dots (publishProgress) however there is a 10+ second delay before they start because I have them as a part of my AsyncTask which loads once the data is processing (technically - the two should be related - but it visually causes there to be a delay) how can I call this animation when the class first starts instead? I need to remove this visual animation delay.

You can use onPreExecute() and onPostExecute() methods from the AsyncTask to set the loading before/ remove it after the work is done.
try:
protected void onPreExecute() {
setProgressImgView(R.drawable.loading_full,
R.drawable.loading_empty, R.drawable.loading_empty,
R.drawable.loading_empty, R.drawable.loading_empty);
}
protected void onPostExecute(InputStream stream) {
setProgressImgView(R.drawable.loading_full,
R.drawable.loading_full, R.drawable.loading_full,
R.drawable.loading_full, R.drawable.loading_full);
// This method is called to parse the response and save the
// ArrayLists
success();
}

I know the application is crashing because of a null value in the code shown above - but I need a bit of assistance figuring out what might be causing it to be null.

If you are sure that this line
nameArr = handler.getnameArr();
gives the NPE then you know the problem must be that handler is null at this point. That is the only way this line will throw a NPE. And from looking at that massive code, it definitely looks like handler is not instantiated before you call the method that uses it (getArrayLists();). You declare it here
XmlParserHandlerFinal handler;
but you never give it a value before trying to use it.
You will need to instantiate it in this Activity before calling a method on it such as getnameArr();. You instantiate it in the other Activity but not in this one.

I'm setting a breakpoint at:

It is not called.
The call to it is at
public int InsertAPN() throws SecurityException {
int id = -1;
if (i < nameArr.size()) {
for (i = 0; i < nameArr.size(); i++) {
ContentValues values2 = new ContentValues();
values2 = getValues();
That call is in a loop over each element of nameArr, which initialized with zero elements:
public ArrayList<String> nameArr = new ArrayList<String>();
Hence the loop will run zero times. The only function that adds elements to the List is the getnameArr() function, which is never called.

String Fails to pass between two activities

I'm passing two strings between two activities and for some strange reason, the strings aren't being passed. I've done all the correct protocols and nothing seems to work, despite tinkering around with the code for several hours, I'm sure it's an simple solution, but I have no clue, what's so ever.
1st Class:
public class LogIn extends Activity implements OnClickListener {
Button ok, back, exit;
TextView result;
EditText pword;
String password;
EditText uname;
String username;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Login button clicked
ok = (Button) findViewById(R.id.btn_login);
ok.setOnClickListener(this);
result = (TextView) findViewById(R.id.lbl_result);
}
//create bracket.
public void postLoginData() {
uname = (EditText) findViewById(R.id.txt_username);
uname.getText().toString();
pword = (EditText) findViewById(R.id.txt_password);
pword.getText().toString();
Bundle basket = new Bundle();
basket.putString("keypass", password);
basket.putString("keyuname", username);
Intent a = new Intent(LogIn.this, ChatService.class );
a.putExtras(basket);
startActivity(a);
// Create a new HttpClient and Post Header

/* login.php returns true if username and password is equal to saranga */
HttpPost httppost = new HttpPost("http://gta5news.com/login.php");
try {
// Add user name and password
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("username", username));
nameValuePairs.add(new BasicNameValuePair("password", password));

Try this way.
Intent a = new Intent(context, MyActivity.class);
a.putExtra("String1", "Hello World");
context.startActivity(a);
and
Bundle extras = getIntent().getExtras();
String s1 = extras.getString("String1");

You should add both 2 activity in Mainfest.xml file

Check have you register your activity in manifest file.
