Quick hack: Precompiling APK files during Android AOSP build

Posted on 23/02/2017 by Robert Foss

By precompiling APK files during AOSP build a few minutes can be shaved off of the development iteration time on most commonly found Android hardware.

Enable precompilation

cd /opt/aosp_checkout/

find . -name BoardConfig.mk
./device/huawei/angler/BoardConfig.mk
./device/generic/mini-emulator-x86/BoardConfig.mk
./device/generic/arm64/BoardConfig.mk
./device/generic/mini-emulator-x86_64/BoardConfig.mk
./device/generic/mini-emulator-armv7-a-neon/BoardConfig.mk
./device/generic/mips/BoardConfig.mk
./device/generic/mips64/BoardConfig.mk
./device/generic/x86_64/BoardConfig.mk
./device/generic/mini-emulator-arm64/BoardConfig.mk
./device/generic/mini-emulator-mips/BoardConfig.mk
./device/generic/x86/BoardConfig.mk
./device/generic/armv7-a-neon/BoardConfig.mk
./device/generic/mini-emulator-mips64/BoardConfig.mk
./device/lge/bullhead/BoardConfig.mk
./device/linaro/generic/linaro_x86_64_only/BoardConfig.mk
./device/linaro/generic/linaro_arm64/BoardConfig.mk
./device/linaro/generic/linaro_arm64_only/BoardConfig.mk
./device/linaro/generic/linaro_x86_64/BoardConfig.mk
./device/linaro/generic/BoardConfig.mk
./device/linaro/generic/linaro_arm/BoardConfig.mk
./device/linaro/hikey/hikey/BoardConfig.mk

# Edit the BoardConfig.mk that you are using for your build
cd device/linaro/generic/
nano BoardConfig.mk

# Add the config option
WITH_DEXPREOPT := true

# Propagate the new settings
make defconfig
make all

 

Increase system partition size

Depending on the previous system partition size and how many APKs that are built, you may need to increase the system partition size.

nano configs/defconfig

# Change the below variable to something big enough to house all of you binaries
CONFIG_BOARD_SYSTEMIMAGE_PARTITION_SIZE=1100000000

# Propagate the new settings
make defconfig
make all

 

Thanks!
