Another question about using Global variable class, and extending Application. Hopefully it varies enough not to be considered a duplicate. I have read these great questions and answers.
Asynchronous programming best practices
How to use global class variables in android
Although I understand how these relate to my current problem, being that Im a total novice I have 2 main issues.
1- Im not quite sure how to apply these solutions, but I will try to figure it out on my own.
2- The second and biggest issue is, what part of my code should I actually even try to migrate over to a Global Class, or a helper class.
So I have 3 classes, Section1.java, Section2.java, Section3.java, which essentially do the same thing, in the same way, using the same methods, they even use almost exact xml layouts(only the xml's name and the drawable's with in each xml changes). The only difference is what they accept as a correct result.
My questions regarding my second point of concern, are under the pasted code.
Here is the code from from Section1.java (rough, looong spagetthi code)
Section1.java
public class Section1 extends Activity implements OnClickListener, OnInitListener{
private TextToSpeech myTTS;
ListView lv;
private ProgressDialog dialog;
static final int check = 111;
static final int checka = 222;
static final int checkb = 333;
TextView speak;
private int MY_DATA_CHECK_CODE = 0;
int counter_score;
RatingBar rb_cooking;
MediaPlayer ourSong;
ImageView display,image1,image2,image3;
int gotLetterA, gotLetterB,gotLetterC
int counter_score_a;
int counter_score_b;
int counter_score_c;
@Override

checkTTSIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);

I would post Section2.java, Section3.java, but there are only 4 things in the code that change.
1-The xml layout, which is itself an exact copy.
setContentView(R.layout.section1);//changes to setContentView(R.layout.section2),setContentView(R.layout.section2) accordingly
2-The accepted result as right answer of what is spoken.
if(results.contains("hey") || results.contains("a") || results.contains("ay") || results.contains("add")|| results.contains("day")||results.contains("A")){//to whatever the correct answer is for that class
3-The amount questions that need to be right to move to the next activity
if(counter_score == 3){
4-The activity where my bundle is being sent
Intent nextAct = new Intent(Section1.this, Result_Section1.class);
Im aware I can build a Global class for variables.
So finally my questions.
As I read here, I can not build a Global Class for say the AlertDialog's, because if I understand correctly dialogs require a Context and thats part of the View class.
Q1.Could I build a public class MyAlertDialogs extends View { to hold my dialogs?
As I read here, Im aware I can build a Global class to handle OnclickListener.
Q2.Can I have the the SpeechRecognizer Intent or the TextToSpeech Intent on that global class?
