Requirements on Debian 7.x

echo "deb http://apt.postgresql.org/pub/repos/apt/ wheezy-pgdg main" > /etc/apt/sources.list.d/pgdg.list wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -

  libffi-dev supervisor git-core 

Deployment

Make it sure PostgresSQL and RabbitMQ services are up and running;

service postgresql start service rabbitmq-server start 

Follow steps for deployment (or use Dockerfile [TODO]);

  • First of all setup PostgreSQL server and create an user and database. You can get help from Debian PostgreSQL Documentation.

      postgres=# CREATE USER mypguser WITH PASSWORD 'mypguserpass';
    postgres=# CREATE DATABASE mypgdatabase OWNER mypguser; 
  • It's recommended to install required python dependency packages by using virtualenv.

      virtualenv --no-site-packages env
    source env/bin/activate
    pip install -r pns/requirements.txt 
  • Copy and edit sample ini file and set environment variable PNSCONF according to path of config file.

      cp pns/config_sample.ini ~/config.ini
    vi ~/config.ini
    export PNSCONF="$HOME/config.ini" 
  • Create tables

      export PYTHONPATH=$PYTHONPATH:$HOME/pns
    python -c "from pns.models import *; db.create_all()" 
  • Now you can test your web service is running

     python pns/pns/run.py  * Running on http://localhost:5000/ 

Congrats! You are done. Now we have to daemonize workers and web service application.

  • Copy sample supervisor configuration file and edit executables and paths

      cp pns/supervisor_sample.conf /etc/supervisor/conf.d/pns.conf
    service supervisor restart 

    Look at Supervisor Documentation page for extra configuration options.

  • It's recommended to use nginx to proxying requests to gunicorn. pns/nginx_sample.conf file includes a basic setup for proxy_pass

APNS Feedback Service

The Apple Push Notification service includes a feedback service to give you information about failed remote notifications. When a remote notification cannot be delivered because the intended app does not exist on the device, the feedback service adds that device’s token to its list. Remote notifications that expire before being delivered are not considered a failed delivery and don’t impact the feedback service. By using this information to stop sending remote notifications that will fail to be delivered, you reduce unnecessary message overhead and improve overall system performance. APNS Documentation

To start benefit from feedback service you can setup a cron. Edit sample configuration file pns/pns_cron_sample.sh and copy under preferred cron folder (cron.hourly, cron.daily etc.).

cp pns/pns_cron_sample.sh /etc/cron.daily/pns chmod +x /etc/cron.daily/pns 

Running Database Migrations

Change username and password in alembic.ini and run following command in application root directory (be sure PYTHONPATH and PNSCONF environment variables are set);

alembic upgrade head 

Resources

The HttpResponseCache library provides transparent and automatic caching of HTTP and HTTPS requests that use the java.net.HttpUrlConnection classes.

For information on how to use HttpUrlConnection, refer to the Android documentation - don't worry, the information also applies to non-Android Java.

Smooth activity switch animation.

PoppyView is a library which implements view on the bottom which come and go relative to the user scroll.

Just add the library to your application as a library project. And don't forget that your project must use NineOldAndroids.

A small library replicating the new dialogs in Android L.

Just as there was Retroweaver et al. for running Java 5 code with generics on Java 1.4, Retrolambda lets you run Java 8 code with lambda expressions on Java 7 or lower. It does this by transforming your Java 8 compiled bytecode so that it can run on a Java 7 runtime. After the transformation they are just a bunch of normal .class files, without adding any runtime dependencies.

ViewServer is a simple class you can use in your Android application to use the HierarchyViewer inspection tool.

ViewServer requires the Android SDK r12 or higher. http://developer.android.com/sdk/index.html
