Here is the complete working example, hope it help for future reader. What the app do is sign in(Sign In API included name and email) first, then request birthday & gender(People API) authentication, and save it to SharedPreferences for reuse on next launch. Finally it will print basic info and advanced (gender & birthday) info.

Reminder:
- Add
<uses-permission android:name="android.permission.INTERNET" /> in AndroidManifest.xml.
- Add
implementation 'com.google.android.gms:play-services-auth:12.0.1', implementation 'com.google.apis:google-api-services-people:v1-rev255-1.23.0', and implementation 'com.google.api-client:google-api-client-android:1.23.0' in dependencies {} of build.gradle.
- In my case I downgrade
compileSdkVersion, targetSdkVersion, and appcompat-v7 from 27 to 26 since I got warning after #2 dependencies added.
- Add
signingConfigs {
debug {
storeFile file('<path to jks file>')
keyAlias '<your key alias>'
keyPassword '<your key password>'
storePassword '<your store password>'
}
}
in build.gradle, which jks file generated from Build -> Generated Signed APK... -> Create new...
keytool -exportcert -keystore <path to jks file> -list -v to get SHA1 hex key, then visits play console, fill in project name, app package name, SHA1 hex key.- Enable People API at https://console.developers.google.com/apis/library/people.googleapis.com/?project=[your project id]", which project id can get from play console. Note that it's not project name.
- I noticed no such
Scopes.BIRTHDAY in library, so I have to hard-coded the birthday endpoint URL"https://www.googleapis.com/auth/user.birthday.read", which the link can get from https://developers.google.com/people/v1/how-tos/authorizing#profile-scopes OR "Show Scopes" in "Try it API" panel at https://developers.google.com/people/api/rest/v1/people/get
- Birthday is a list, and it may loop 2 date items, one item lack of year in my case. My code always replace to save those 2 items. There may be better way to handle it.
- Gender only able to return if it's not private. Birthday no such restriction.
- Since Android device need ~1 minute delay to get new created account name, so you might need to use PROFILE scope instead of simple
account.getGivenName() and account.getFamilyName().
