1 2 In order to build using prebuild NDK versions, this project must be initialized from a custom repo using: 3 mkdir android-games-sdk 4 cd android-games-sdk 5 Corp -> repo init -u persistent-https://googleplex-android.git.corp.google.com/platform/manifest -b android-games-sdk 6 AOSP -> repo init -u https://android.googlesource.com/platform/manifest -b android-games-sdk 7 repo sync -c -j8 8 9 Then: 10 ./gradlew gamesdkZip 11 will build static and dynamic libraries for several NDK versions. 12 13 By default, the gradle script builds target archiveZip, which will use a locally installed SDK/NDK pointed 14 to by ANDROID_HOME (and ANDROID_NDK, if the ndk isn't in ANDROID_HOME/ndk-bundle). 15 16 It is also possible to build from a direct AOSP checkout, but then you won't be able to build for multiple 17 NDKs: archiveZip will still work but the gamesdkZip target will fail. 18
