Instructions to build sqlcipher for Android

* Extract Android build toolChain from NDK

1. Download android-ndk-r10e

2. Create android build toolchain

$NDK/build/tools/make-standalone-toolchain.sh --arch=arm --install-dir=<ANDROID_BUILD_TOOLCHAIN>

3. Export some environment variables

export ANDROID_BUILD_TOOLCHAIN=<ANDROID_BUILD_TOOLCHAIN>

export PATH=$ANDROID_BUILD_TOOLCHAIN/bin;$PATH

export CROSS_SYSROOT=$ANDROID_BUILD_TOOLCHAIN/sysroot # important for cross compile

* Build OpenSSL

1. Download openssl-1.1.0g

2. Build OpenSSL

./Configure no-shared --cross-compile-prefix=arm-linux-androideabi- android-armeabi

make

make install DESTDIR=$CROSS_SYSROOT

* Build sqlcipher

./configure --disable-shared --enable-static=yes --enable-tempstore=yes CFLAGS="-fPIE -DSQLITE_HAS_CODEC -I$CROSS_SYSROOT/usr/local/include" LDFLAGS="-fPIE -pie -L$CROSS_SYSROOT/usr/local/lib $CROSS_SYSROOT/usr/local/lib/libcrypto.a" --host=arm-linux-androideabi
