ABTcore

About

This provides a back-end to ABT and is derived from core_engine of GNUkhata.

Sqlite3 is used as a database engine.

We have completely dropped an idea of stored procedures, instead we have implemented an Object relational mapping using SQLAlchemy

Android-xmlrcp client side (java)library is used to communicate with xmlrpc's of ABTcore. It uses twisted module for executing rpc calls. A server reactor from the twisted library starts a service on port 7081 with a published object and listens on given port.

Install

Note: We highly recommend to perform this procedure on an Ubuntu based system. User are free to use other variant of GNU/Linux provided the package dependencies are met.

  1. Please remember that currently adb supports only 32-bit systems, if your processor is 64-bit, then install ia32-libs-multiarch library to support multi-architecture. On Ubuntu system, install ia32-libs-multiarch using

    sudo apt-get install ia32-libs-multiarch

  2. Connect Aakash to your system using an USB data cable.

  3. Download install.zip on your system

  4. Extract the zip file using

    unzip install.zip

  5. cd to install directory

    cd install

  6. and execute install.sh

    sudo ./install.sh

Wait for the script to copy all necessary files to Aakash. After successful installation the device will reboot for changes to take effect.

Usage

WARNING: This section is for advance users only! Developer who want to contribute to this project can try this section. We are not responsible for any damage to the device.

on x86 system

clone this repo by typing

git clone https://github.com/androportal/ABTcore.git

Dependencies

  • libpcre3
  • libpcre3-dev
  • libreadline5
  • libreadline6-dev
  • libpq5
  • sqlite3
  • python-pip
  • python-sqlalchemy
  • python-twisted
  • python-dateutil

On an Ubuntu machine, these dependencies can be installed using apt-get

sudo apt-get install libpcre3 libpcre3-dev
sudo apt-get install libreadline5 libreadline6-dev libpq5
sudo apt-get install python-pip python-sqlalchemy
sudo apt-get install python-twisted
sudo apt-get install python-dateutil

to run the server, cd to directory ABTcore/ and type

sudo ./abtstart

Installing ABT frontend

Please visit README section of ABT on installaion and relevant changes in the source files

on Aakash (ARM-arch)

You have to setup a PATH for adb on your system, please refer ABT's README section "Importing ABT as an eclipse project". Once you have downloaded the SDK, update it to API-15(Icream Sandwich). and export adb's PATH using

SYNTAX

export PATH=/home/${HOME}/<path-to-your-sdk/platform-tools:$PATH

for example, if you have downloaded Android's SDK in $HOME, then your command should be

export PATH=/home/andro/android-sdk-linux/platform-tools:$PATH

assuming $USER is andro in this case.

Please remember that adb only supports 32-bit system, if your system is 64-bit, you have to install ia32-libs-multiarch library to support multi-architechture. On Ubuntu system, install ia32-libs-multiarch using

sudo apt-get install ia32-libs-multiarch

Once adb is in place, attach USB data cable provided with Aakash to your linux system and other end(USB Type-2 micro) to Aakash.

You need to push debug.sh to /data/local/ to start a server manually. Visit install directory within ABTcore (your cloned repo)

cd ABTcore/install/

and push debug.sh to /data/local/

./adb push debug.sh /data/local/

Once ABTcore and debug.sh is pushed inside the device, do

adb shell

to get bash prompt on device. You have to enter the chroot environment using

cd /data/local/
sh debug.sh

If your bash prompt says root@localhost, then you are inside the chroot!. Now type

cd /root/ABTcore
./abtstart

to start the server.

Now you can install an APK and start working

Updating present image

If you want to work with update core, then you can push the content of ABTcore/ directory inside Aakash to PATH /data/local/abt/root/ABTcore (please refer this link for adb usage).

to push latest content of ABTcore to /data/local/abt/root/ type

adb push ABTcore /data/local/abt/root/ABTcore

Note

ABTcore was originally derived core_engine. We have modified the code to work with Android.
