Android Intent.getStringExtra() returns null

Question

This is how strings are being added to Extras:

Intent i = new Intent();
i.putExtra("Name", edt_name.getText());
i.putExtra("Description", edt_desc.getText());
i.putExtra("Priority", skb_prior.getProgress());
setResult(RESULT_OK, i);
finish();

This is how I try to extract them in onActivityResult():

String name = data.getStringExtra("Name");
String desc = data.getStringExtra("Description");
int prior   = data.getIntExtra("Priority", 50);

But after the second code block name and desc are null's, though prior has it's proper value. Moreover, in debugger I can see, that data.mExtras.mMap contains needed Strings, but only after first request to it.

Are you sure prior has proper value and not default one (50) which you are setting? – Iolanthe

Yes, but the problem was in edt_name.getText(), which returns not String but some heir class, may be? – Gynoecium

Answer 1

When you insert your Extras trying adding .toString()

i.putExtra("Name", edt_name.getText().toString());

You are seeing the CharSequence value in there but you need to convert it to a String to call getStringExtra(). Obviously, just do this for the Strings. You see the correct value for your int because that is done correctly

Thanks, it works, as well as "" + edt_name.getText(), which looks not as pretty :) – Gynoecium

It works because "" is a String literal and you're adding to it. It works the same way as "" + 2 comes out to "2". Whatever is being added to the literal is converted to a String via their own class's toString function. – Checkerwork

@codeMagic, Why do you say that it's an object? Isn't it CharSequence? – Reflector

@Reflector Yes, it would actually return a charSequence – Pliocene

@Pliocene In my case, issue is not this one though, as I tried to use same receiver for different Alarms this issue triggered, don't know why? but I end up adding each individually it worked, the purpose of intent in this new approach is now gone.. – Alurta
