Activity Reloads with Previous Selected Data Bug

So i developed an android news app. A spinner item is available on the toolbar and data reloads according to spinner selection. However, when the data reloads, for some of the items, it directly loads the relevant content but for some others, it loads the previously selected spinner data. Current data for the current item only shows after reloading same spinner data using the swipe refresh functionality which i had implemented. I want the correct data relevant to that selection to load the first time itself without having to refresh all the time.
Below is my MainActivity where all these functions are called.

I discovered that from API level 3, one can use the onUserInteraction() on an Activity with a boolean value thereby determining the user's interaction.
Find the documentation in the link below.
http://developer.android.com/reference/android/app/Activity.html#onUserInteraction()
#Override
public void onUserInteraction() {
super.onUserInteraction();
userInteracts = true;
}
The my adjustment goes as thus in the MainActivity.java
mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
int check = 0;
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (IsInteracting) {
Intent intent = getIntent(); //MainActivity
String itemSelected = mySpinner.getItemAtPosition(mySpinner.getSelectedItemPosition()).toString();
//TODO: DONE
prefManager.spinWriteString(itemSelected);
Toast.makeText(getApplicationContext(), "Constituency News Now Showing", Toast.LENGTH_SHORT).show();
startActivity(intent);
finish();
}
}

Android cannot be referenced from a static context

I'm a beginner on Android and this is the first I'm creating an app named GeoQuiz which basically has a few questions and the user has to click true/false or request the answer with the cheat button.I'm getting this one line of error related with a non-static an a static context in line 138,what am I doing wrong? I'm trying that every time i click on the button cheat, it open the other window that is under a different .xml file and in an another java class

*/
public class cheatActivity extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cheat);
}
}

Replace
Intent intent = new Intent(QuizActivity.this, cheatActivity.startActivity(intent));
with
Intent intent = new Intent(QuizActivity.this, cheatActivity.class);
startActivity(intent);
See the docs for more details..

Not sure what you're doing there, but you need to reference the other activity class. Simply calling startActivity is enough, because it will be implicitly called from QuizActivity.this.
Intent intent = new Intent(QuizActivity.this, cheatActivity.class);
startActivity(intent);
To save you from future errors choose one activity class that you will be using either Activity or ActionBarActivity. The latter is from the support package.

Android CountDown Timer in Quiz Application

I have made a quiz application which include 5 questions. I have made a ResultActivity page which displays result of the quiz.
I have added a countDown timer of 20 sec for each question. When the Countdown timer finishes it moves to the next question automatically. When the questions are finished it should move to the ResultActivity page to display result.
I have only one issue...
Afetr reaching my last Question..if i does not select any answer and timer is finished the applicaton is not moving to my ResultActivity page..The timer is getting started again and again on the same question until i select any option
Here is my code:

This is because Your return false statement will never be reached if the user has made no choice:
if (rda.isChecked() || rdb.isChecked() || rdc.isChecked()){}
in this if else statement You will return false later. But if none is selected, You automatically will return true because the code block inside this statement above will not be rached. And then in Your timer You say:
if (getNextQuestion(false)) {
// Start The timer again
countDownTimer.start();
}
getNextQuestion is allways true if the user makes no choice, so the timer starts again and again.
