Java code to show action on x amount of presses?

I have an iOS app that I worked on some time ago, and the function it uses I like, and would like to somehow get it to work on some Android code I have.
At the top of my MainActivity I have
SharedPreferences sharedpreferences;
public static final String MyPREFERENCES = "nShownLobby";
on my onCreate I have
sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
And I am calling this method
changeTextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v){
long nb_shown_lobby = PreferenceManager.getDefaultSharedPreferences(MainActivity.this).getLong("nShownLobby", 0);
++nb_shown_lobby;
if ((nb_shown_lobby % 20) == 0) {
this.turnAround();
}
int random = (int) (Math.random() * manyDifferentStrings.length);
if (random == oldVaue) {
random = (int) (Math.random() * manyDifferentStrings.length);
}
changingText.setText(manyDifferentStrings[random]);
oldVaue = random;
try {
mySound.start();
} catch (NullPointerException e) {
mySound = MediaPlayer.create(MainActivity.this, R.raw.sound);
}
}
private void turnAround() {
//Do something here
Log.i("Do Something ", "");
}
});
The intention is that after every 20 presses, the turnAround() method is called but it does not... It just gets ignored - I am guessing I have missed something?

**According to your question your code should be like this**
private SharedPreferences sharedpreferences;
private SharedPreferences.Editor editor;
private static final String MyPREFERENCES = "nShownLobby";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
editor = sharedpreferences.edit();
changeTextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v){
int nb_shown_lobby = sharedpreferences.getInt("nShownLobby", 0);
if ((nb_shown_lobby % 20) == 0) {
turnAround();
}
nb_shown_lobby += 1;
editor.putInt("nShownLobby", nb_shown_lobby);
editor.commit();
int random = (int) (Math.random() * manyDifferentStrings.length);
if (random == oldVaue) {
random = (int) (Math.random() * manyDifferentStrings.length);
}
changingText.setText(manyDifferentStrings[random]);
oldVaue = random;
try {
mySound.start();
} catch (NullPointerException e) {
mySound = MediaPlayer.create(MainActivity.this, R.raw.sound);
}
}
});
}
//created this in activity, not in the button onclick
private void turnAround() {
//Do something here
Log.i("Do Something ", "");
}

I have an Issue in a Calculator app - how to fix it?

The Problem I have is how to change last operation by pressing the new operation the New Operation Will Override the previous

I wanted to make the java code as simple as I can so I've just added the lines for my question. What I'm trying to do is
android:onClick="onePointForTeamA"make this button only clickable when foulCounterA = 5 Failed to add if (foulCounterA = 5); inside public void foulCountForTeamA(View v) {
It gave me an error that way. Says required: boolean, found: int.
What should I do with the code? Any help will be appreeciated

Regarding your concrete question, the syntax of if (foulCounterA = 5); is wrong, because the equation check is have to made by == operator.
So the correct syntax would be if (foulCounterA == 5);
As #OH GOD SPIDERS wrote in the comment, you should check the basics of java operators.
Also I recommend You to search for the answer before asking a new question.

Global Variable in CountDownTimer not changing

Please assist, I have the following code that I have tried executing in diffirent places with the following results:
1) When placed in the on create it keeps resetting to 60 seconds
2) When placed in onResume it seems to work perfectly until the play again button is pressed then it starts counting down from the last onPause position
3) When placed in the playAgain method it crashes
Code:

countDownTimer = new CountDownTimer(timeRemaining, 1000) {

I have the global var set and assumed that resetting it in the onFinnish within the countdown timer should reset it but it does not.
Thanks

Fields (what you called Global vars) are are not guranteed to be restored on activity recreation and can be GC anytime. You should rather create var in on create, store them in Bundle onPouse and again recreate them from that Bundle in another onCreate or onResume methods.
Here you have Google Dev's docs about how to handle activity creation, recreation and finalization https://developer.android.com/training/basics/activity-lifecycle/recreating.html
So basicly 1) it resets to 60 secs because it is recreated everytime you get back to your activity (from diffrerent app aor different activity)
2) idk where is your "play again" thing and I am not going to go into that code
3) countDownTimer.start(); probably here it crashes with NPE am i right? (I am reading my crystall ball right now)
Read the full Google's tutorial about acitivity lifecycle and you wont have any troubles fixing your code.
