Below is a summary of current issues currently faced by customers releasing apps in China.
Google App Store
There is no access to the Google Play Store in China. Because of this, DoubleDutch is not responsible for hosting the app in China. You will receive a .apk handoff file, and it is recommended that you either host the file on your event webpage, or a suitable China app store (Baidu, Tencent, 360, Wendoujia, etc.)
Interactive Maps won’t work without Google Play Services; they will result in an error message. It is possible to side-load Google Play Services but attendees will not do this. The short-term option is to create web-based maps for users without Google Play Services. The downside with this is there is no offline mode and map labels are visible.
PDFs currently open in a Google Docs web view for some versions of the app (Android doesn’t support PDFs well out of the box, compared to iOS. However, in China, Google Docs is blocked. The proposed solution is to convert the document from PDF to HTML.
Push Notifications will not work without Google Play Services. Instead, any messages sent by the organizer will be received as in-app notifications.
Xiaomi (Other Chinese) Device Compatibility
Issues may vary with phones from other Chinese manufacturers. There are numerous brands and Android models out there, so there's no guarantee the app will function properly.
