I am trying above code where I use constructor for initialization of int value and then I try to access that value inside onCreate method but the problem is that int value inside onCreate method is always 0 while the value is shown correctly inside constructor. Anyone can help me with that...Thanks in Advance.

Screenshot is shown for more clarification:
enter image description here

All I want to access the constructor value and assign it to variable inside class so that to make it global.

I did not find any suitable answer related to my problem on Stack Overflow

Instead of using the constructor to pass a certain value in an application context, you should try to pass it as a Bundle to the OnCreate function. Here is a link to the documentation : https://developer.android.com/reference/android/os/Bundle . ` @Override
public void onCreate(Bundle putYourInfoHere) {
super.onCreate(putYourInfoHere);

    this.presetOption = putYoutInfoHere.getInt
//Notification Preset1
String titledText1 = "Scan Docs With A.I Filters";
String someBigText1 = "It's been a long time since no document is scanned...";
if (presetOption == 1)
{
createNotification(titledText1, someBigText1);
}
else if (presetOption == 2)
{
//notification Preset2
String titledText2 = "Try ID Car Scan";
String someBigText2 = "Best ever ID card scanning let you scan both side of ID Card on same page more visible";
createNotification(titledText2, someBigText2);
}else if (presetOption == 3)
{
//notification Preset3
String titledText3 = "Try Digital Signature";
String someBigText3 = "Draw or Import digital signature and place it on any document you want.";
createNotification(titledText3, someBigText3);
}else if (presetOption == 4)
{
//notification Preset4
String titledText4 = "D.S.P Ocr feature";
String someBigText4 = "Let's convert text image into editable text for you...";
createNotification(titledText4, someBigText4);
}
else
{
createNotification(titledText1, someBigText1);
}
}`

I am assuming that you get you're presetValue in your constructor from another page. If so, you should implement a function to store the value in your Bundle as shown in the documentation.
