Changelog

Updated CHANGELOG.md

[sfriedman-stripe]

Wasn't clear on whether we actually need the next_action_spec given #8053

[jaynewstrom-stripe]

I've been leaving the JSON exactly as it is on the server to try to make things consistent and not confusing.

[porter-stripe]

On iOS leaving this next_action_spec would probably make handling the next action fail FWIW.

[sfriedman-stripe]

Removed this after Jay and I chatted. It's not in the server spec anyway

[sfriedman-stripe]

Still need to run the Lokalize script and apiDump, but having some issues with my Java env. Will pair with someone

[sfriedman-stripe]

This is heavily cargo culted from other Activities in the Example app; please lmk if I've faltered

[jaynewstrom-stripe]

Yeah, I think this is the right thing to do for now. I added this as an improvement we can make, but it seems low bar since it's example code.

[jaynewstrom-stripe]

I think we normally put these in donottranslate, as most of the time these are names, and don't get translated.

[jaynewstrom-stripe]

The lokalise build won't fail if you do that too. See others here:

stripe-android/payments-ui-core/res/values/donottranslate.xml

Line 31 in c766796

<string name="stripe_paymentsheet_payment_method_twint">TWINT</string>

[sfriedman-stripe]

Oh nice! Android Studio warns against adding anything to anything but the translations editor, so I didn't realize some were in different files
