Wrong calculation after using sharedpreferences

I'm building an app to check prime numbers and display them. the user need to be able to save the number and load it upon restart of the app.
I have problem when retrieving the saved int from Sharedprefrences. the codes saves the int and loads it on the "loaddata" function. But when I start checking if the saved in is a primenumber, the code jumps 2 primenumbers. Eg if I save "11", the next primenumber should be "13" but it jumps to "19".
Would be great if someone could point into the right direction since i'm a bit of newbie.
public class MainActivity extends AppCompatActivity {
private TextView textView;
private EditText editText;
private Button applyPrimeButton;
private Button saveButton;
private Button loadButton;
public static final String SHARED_PREFS = "sharedPrefs";
int max = 500;
int j = 2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.textview);
editText = (EditText) findViewById(R.id.edittext);
applyPrimeButton = (Button) findViewById(R.id.apply_prime_button);
saveButton = (Button) findViewById(R.id.save_button);
loadButton = (Button) findViewById(R.id.load_button);
applyPrimeButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
for (int i = j; i <= max; i++) {
if (isPrimeNumber(i)) {
textView.setText(i+"");
j = i+1;
break;
}
}
}
});
saveButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
saveData();
}
});
loadButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
loadData();
}
});
}
public boolean isPrimeNumber(int nummer) {
for (int i = 2; i <= nummer / 2; i++) {
if (nummer % i == 0) {
return false;
}
}
return true;
}
public void saveData() {
SharedPreferences sp = getSharedPreferences(SHARED_PREFS, Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
int nummer = Integer.parseInt(textView.getText().toString());
editor.putInt("prime_save", nummer);
editor.commit();
Toast.makeText(this, "Data saved", Toast.LENGTH_SHORT).show();
}
public void loadData() {
SharedPreferences sp = getSharedPreferences(SHARED_PREFS, Activity.MODE_PRIVATE);
int nummer = sp.getInt("prime_save",0);
textView.setText(String.valueOf(nummer));
}
}

Several issues:
You are not updating j to the correct value when loading data, and instead relying on what you are displaying in the textview.
To find prime number, it is enough to check until the square root of the original number and not half of it.
Try this:
applyPrimeButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(j<max ){
if (isPrimeNumber(j)) {
textView.setText(j+"");
j++;
}
}
}
});
public void saveData() {
SharedPreferences sp = getSharedPreferences(SHARED_PREFS, Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.putInt("prime_save", j);
editor.commit();
Toast.makeText(this, "Data saved", Toast.LENGTH_SHORT).show();
}
public void loadData() {
SharedPreferences sp = getSharedPreferences(SHARED_PREFS, Activity.MODE_PRIVATE);
int nummer = sp.getInt("prime_save",0);
j = nummer;
textView.setText(String.valueOf(nummer));
}

There is no onClickListener within your Activity. I would recommend creating a "next()" function, and then, for each of the buttons, do something along the lines of:
btn.setOnClickListener(new View.OnClickListener(){
next()
})

Simple EditText Alert dialog ran before main activity created

Trying to display simple edit text dialog, requesting a string be provided before the rest of my application starts. Currently im trying to make it so the APIKEY of my app is request first thing, then once entered its saved a shared preference and then the dialog will not display. The current code is being reused from a old project of mine. If anybody can help point me in the right direct to making this simple dialog.
public void getapikey() {
AlertDialog.Builder adb = new AlertDialog.Builder(this);
LayoutInflater adbInflater = LayoutInflater.from(this);
View eulaLayout = adbInflater.inflate(R.layout.custom_dialog, null);
editText = (EditText) eulaLayout.findViewById(R.id.editText1);
adb.setView(eulaLayout);
adb.setTitle("Api Key");
adb.setMessage("Welcome to the app, Please input your APIkey below");
adb.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
// CheckBox Confirm for Alert Dialog
public void onClick(DialogInterface dialog, int which) {
String value = editText.getText().toString();
if (editText !=null)
//Unsure about this part above and below
editText = "0"
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("apikey", value);
// Commit the edits!
editor.commit();
return;
}
});
// Preferences For Alert Dialog
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
String apikey = settings.getString("apikey", "0");
if (apikey!=null )
adb.setIcon(R.drawable.ic_launcher);
adb.show();
}
}

// do nothing

i.setClassName("com.example.app",
"com.example.app.CardsTesting");
startActivity(i);
finish();
}
}
};
splashThread.start();
}
}
Still doesnt save the preference after the first time then never displays

//try this one i think it may be work
SharedPreferences settings = PreferenceManager.getSharedPreferences(PREFS_NAME, 0);

How can I make my android app have SharedPreferences as just one set of preferences, so that I can control it and clear the preferences with a button

I am trying to have SharedPreferences once and control it to different methods rather than having different SharedPreferences in different methods. I have SharedPreferences in the onCreate, LoadPreferences, SavePreferences and ClearTextViews methods. I want to make it so that I have preferences saved to the TextViews from entered text in the EditText and then be able to clear them all with a button. Please help me if you can. Here is the relevant code:
public class notesActivity extends Activity implements OnClickListener

Open tutorial on first run doesn't work properly

I have a tutorial in my app showing up when a user runs it for the first time
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
if (firstRun == true) {
Intent tut = new Intent(MainActivity.this, Tutorial.class);
startActivity(tut);
firstRun = false;
}
}
}, 200);
I have delayed it because without a delay i just get a black screen (the interface doesn't have the time to load)
But doing so i get the Tutorial.class opened many times, what am i doing wrong?
EDIT:
Here is some more code, i won't paste all of it since it would be only too long to read and it wouldn't be relevant to the problem
I save my preferences like this
#Override
protected void onStop(){
super.onStop();
// We need an Editor object to make preference changes.
// All objects are from android.context.Context
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putInt("Counter1", counter);
editor.putInt("Counter2", counter2);
editor.putBoolean("FirstRun", firstRun);
editor.putString("Label1", label1S);
editor.putString("Label2", label2S);
editor.commit();
}
protected void onPause(){
super.onPause();
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putInt("Counter1", counter);
editor.putInt("Counter2", counter2);
editor.commit();
}
Here is how i restore them inside the onCreate();
// Restore previous settings and data
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
int counterRestored = settings.getInt("Counter1", 0);
int counter2Restored = settings.getInt("Counter2", 0);
boolean firstRunRestored = settings.getBoolean("FirstRun", true);
String label1Restored = settings.getString("Label1", "Counter 1");
String label2Restored = settings.getString("Label2", "Counter 2");
counter = counterRestored;
counter2 = counter2Restored;
firstRun = firstRunRestored;
label1S = label1Restored;
label2S = label2Restored;
renameLabel();
calculateTotal();
This is my second activity Tutorial.class
public class Tutorial extends MainActivity{
ImageButton btnSkip, btnSkip2, btnNext, btnNext2;
RelativeLayout tutorial, tutPage1, tutPage2;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tutorial);
btnSkip = (ImageButton) findViewById(R.id.btn_skip);
btnNext = (ImageButton) findViewById(R.id.btn_next);
btnSkip2 = (ImageButton) findViewById(R.id.btn_skip2);
btnNext2 = (ImageButton) findViewById(R.id.btn_next2);
tutorial = (RelativeLayout) findViewById(R.id.tutorial);
tutPage1 = (RelativeLayout) findViewById(R.id.page1);
tutPage2 = (RelativeLayout) findViewById(R.id.page2);
btnSkip.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
finish();
}
});
btnSkip2.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
finish();
}
});
btnNext.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
tutPage1.setVisibility(View.GONE);
tutPage2.setVisibility(View.VISIBLE);
}
});
btnNext2.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
tutPage1.setVisibility(View.VISIBLE);
tutPage2.setVisibility(View.GONE);
tutorial.setVisibility(View.VISIBLE);
finish();
}
});
}
}

why don't you try
if(firstRun){
firstRun = false;
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
Intent tut = new Intent(MainActivity.this, Tutorial.class);
startActivity(tut);
}
}
}, 200);
}

The value of firstRun will not be stored persistantly over several runs.
You should store this value in SharedPreferences so that it will retain its value even after the app has been closed. You can find a tutorial on how to use SharedPreferences here.
