Android client app

The app for Android allows to post blog entries directly from a Smartphone or tablet. The pictures are being scaled down to blog size before they are transferred to the arcoiris blog server thus reducing the amount of data being sent. In offline mode new blog entries are stored on the mobile device and can be sent to the server when a network connection becomes available.
