How to call a method unless it was opened as an activity?

Is it possible to trigger a method when an Activity is opened by an intent.
I found onNewIntent() on articles but I have no idea how that works.

onNewIntent()

For example if I had the method loadData(). In the loadData method I will receive an Intent and get an array extra.

loadData()

loadData

public void loadData()
Bundle bundle = getIntent().getExtras();
contactsList = (ArrayList<Contact>)bundle.getSerializable("array");



But i only want loadData() to be called unless it is opened by an intent or it will throw a bug.

This article How to call a method using intent was similar to what I wanted because it seems like the getIntent is called in the oncreate. I don't know if that will work or not.

getIntent

oncreate

Any help would be appreciated, thanks.

Check intent have values or null .if its have the value call your method

if(getIntent().getExtras() != null)

loadData()



You can send a parameter to the Activity and check if that parameter exists to trigger the method. Does this fit what you want?

Intent intent = new Intent(this, OtherActivity.class);
intent.putExtra("loadData", true);


In the new activity, check that value:

Boolean loadData = getIntent().getExtras().getBoolean("loadData");
if(loadData) ...
