Building postgresql plugin is pretty straight forward.
If you don't want to build them yourself you can download the plugin here[1]. All you need to do is copy libqsqlpsql.so into /path/to/qt/android_armv7/plugins/sqldrivers/. It's statically linked to libpq!
Setting up Enviroment Variables
Compiling only libpq should work fine with android-9 which is what qt-android is currently compiled with.
export ANDROID_NDK_ROOT="/path/to/android/ndk"
SR="$ANDROID_NDK_ROOT/platforms/android-9/arch-arm"
BR="$ANDROID_NDK_ROOT/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-"
Downloading
Posgresql source can be downloaded from http://www.postgresql.org/ftp/source/ These instructions are only tested on the 9.4.1. Once downloaded extract.
Building
cd into the postgresql directory and run configure
STRIP="$BR"strip RANLIB="$BR"ranlib OBJDUMP="$BR"objdump AR="$BR"ar CC="$BR"gcc CFLAGS=--sysroot=$SR CPP="$BR"cpp CPPFLAGS=$CFLAGS \
./configure --prefix=$SR/usr --host=arm-linux-androideabi --target=arm-linux-androideabi --build="$CHOST" --without-readline
Since android requires that .so files end in .so and not with a version number copy and replace two things in src/Makefile.shlib
"lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION).$(SO_MINOR_VERSION)" with "lib$(NAME)$(DLSUFFIX)" and "lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION)" with "lib$(NAME)$(DLSUFFIX)"
sed -e 's/lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION).$(SO_MINOR_VERSION)/lib$(NAME)$(DLSUFFIX)/g' -i src/Makefile.shlib
sed -e 's/lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION)/lib$(NAME)$(DLSUFFIX)/g' -i src/Makefile.shlib
Next run make. For the driver we only need libpq.
make -C src/interfaces/libpq
Building the plugin
Next download the source for Qt 5 if you don't have it. We only need base http://download.qt.io/archive/qt/5.4/5.4.1/submodules/qtbase-opensource-src-5.4.1.tar.xz After downloading and extracting cd into "qtbase-opensource-src-5.4.1/src/plugins/sqldrivers/psql/"
Run qmake followed by make
qmake "INCLUDEPATH+=/path/to/postgresql-9.4.1/src/interfaces/libpq /path/to/postgresql-9.4.1/src/include" "LIBS+=-L/path/to/postgresql-9.4.1/src/interfaces/libpq/ -lpq"
make install
Build your Android App
Finally to build your android app you'll need to add libpq.so. Add this line to your .pro file
ANDROID_EXTRA_LIBS=/path/to/postgresql-9.4.1/src/interfaces/libpq/libpq.so
