Android - AsyncTask Method Is Not Reached - java

I have an AsyncTask method titled "NetworkTask" which is supposed to query a web service and start a loading animation however the animation never starts and when I set a breakpoint at the line:
private class NetworkTask extends AsyncTask<String, Integer, InputStream> {
I never seem to reach the method NetworkTask and I'm unsure why this might be happening.
Any insight/input as to what might be causing this issue is greatly appreciated.

This isn't a complete answer but too long for a comment and should provide some insight.
I never seem to reach the method NetworkTask
NetworkTask isn't a method, its a class definition for your AsyncTask. When you call execute() on your AsyncTask object the doInBackground() method should start. Put a breakpoint at the first line inside of that method and see if that is reached.
Also, put a breakpoint on the line
else if ((tm.getSimOperator()).equals(getString(R.string.numeric_tmo))
|| (tm.getSimOperator())
.equals(getString(R.string.numeric_att)))
and use the expressions tab to make sure that at least one of those conditions is true. Alternatively, you could put a breakpoint at
TotalSteps = 6;
or anywhere inside that else if and make sure it is reaching the code to execute the AsyncTask.
One more suggestion, since you aren't actually passing anything to doInBackground(), you can remove the empty String from execute() and change the params of your AsyncTask to accept Void params.

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();
}

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.

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++) {

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.

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.
