mentat/ffi

Development flow for Mentat FFI

Android SDK

Android Mentat SDK is one of two first-party consumers (the other one being iOS Mentat SDK).

Binaries produced by cargo build ... are symlinked from within the SDK, and a number of target-specific libmentat_ffi.so binaries are bundled together and distributed with the SDK.

There is a build script at <mentat_root>/scripts/android_build.sh which knows how to cross-compile mentat_ffi for various Android targets.

• ./<mentat_root>/scripts/android_build.sh - compiles for all supported targets
• ./<mentat_root>/scripts/android_build.sh x86 - compiles for x86
• ./<mentat_root>/scripts/android_build.sh x86 arm - compiles for x86, arm

General development flow while working on the Android SDK is:

• (pre) compile for all targets, if you've never done so
• make changes to mentat_ffi and/or mentat
• re-compile mentat_ffi binaries using ./android_build.sh x86. During development it's faster to compile just for the target which matches your emulator, e.g. x86
• make corresponding changes in the Android SDK, try them out from within the bundled sample project
• since binaries are symlinked, no manual copy step is necessary for the Android SDK to pick up the changes
