#### Background
This is the task to add native support for GPay into the Android Wikipedia App in partnership with fr-tech. Adding Native payment method support was one of the proposed enhancements identified for improving donor experience in the apps. Fr-tech and the iOS team have already added support for ApplePay. Adding support for Google / Apple Pay was also a [[ https://meta.wikimedia.org/wiki/Community_Wishlist_Survey_2022/Mobile_and_apps#Accepting_donations_from_mobile_apps | request in the 2022 Wishlist ]].
#### Requirements
- Entry points for flow: 1) From the "Donate" option in settings 2) from an in-app banner
- An option to pay via GPay should be presented when tapping Donate
- The GooglePay option or any branding should not be visible if the user doesn't have GooglePay set-up or is restricted for compliance reasons. In this case, the user should be sent directly to donate.wikimedia.org
- Tapping "Donate with GPay" should launch the Payment Authorization view controller/action sheet
- Tapping "Other payment method" should launch the
#### Technical notes
- The donation flow should be presentable from any context.
- For now, we don't need to keep track of successful donations or keep any local information about donation history. In the future, we may want to record a donation that has occurred to prevent additional asks from being shown, but for this version, no record of donation is required.
- This feature must work well with Dynamic Type and Voice Over.
#### How will we know we are successful?
Indicators:
- 4.0% average CTR across both apps per unique user, with a higher increase in CTR on Android in December
- 30% higher donation completion rate for native payments as compared to web view
Curiosities:
- What percentage of users use native payment method as compared to users paying with Apple pay or Google pay on Web?
#### Designs:
TBA
Can be based on ApplePay general flow (ApplePay Parent task with designs: T288285)
