Create an Android Smart Client program(Client side of a RIA)

General Requirements:

- You must be a company i.e. you must be able to send us a pre-invoice (quote) and also an invoice after payment is made.

- Ability to communicate well in English

Technical Requirements:

- Excellent Android and Java programming skills

- The Smart Client must be tested on real Android devices and must be fully functional without bugs.

- Native Android Java code

Payment details:

We will not pay the provider upfront. Most of the funds will be released upon completing the project.

Detailed technical specification:

A detailed technical specification will be provided after signing an NDA.

Job descriptions:

We are looking for a company to create a Smart Client program (Client side of a Rich Internet Application solution) for Android devices.

Note that this is not a ‘static’ application with predefined windows. Only the Login Screen is static, all other windows are being dynamically created based on XML data streams that the Client receives from the Server.

The Smart Client needs to:

a) Receive the application GUI definition (in a predefined XML format) from the Server, and render the GUI using Android native controls.

b) Be able to interact with the Server-side application by sending application events to the Server (in an XML format).

Predefined RIA User Interface Markup Language (UI XML) language format:

The RIA XML language is used to communicate between the Client and Server. The XML specification defines approximately 200 UI elements/properties, application events etc.

The XML has the following structure:

<-Property Name 1->Value….<-Property Name n->Value

e.g. <-WindowTitle->My Window<-NewControlType->Button<-ControlText->Insert

Typical Control types that the Client needs to be able to ‘draw’ using native Android controls: BUTTON, ENTRY, LISTBOX, CHECKBOX, IMAGE, TEXT, etc.

Example Scenario:

The following example describes a typical Application User - Client - Server interaction loop. Note that Steps performed on the Server side are not part of the project but description is provided for better understanding.

Step 1. (on an Android device): User starts the Client program

The User launches the Client program. A Login Screen appears, asking for login info. The Client sends this info to the Server in a predefined XML format.

Step 2. (on the Server side): User authentication / Application list

The Server authenticates the User and sends a list of applications back to the Client.

Step 3. (on an Android device): User picks an application

The Client receives this list (in XML format), and presents it to the User.

The User selects an application. The Client sends information about this event to the Server (in XML format).

Step 4. (on the Server side): Application started, scanned and transferred

The Server receives information from the Client and launches the appropriate application.

The Server ‘scans’ the application UI elements and sends it to the Client (in XML format).

Step 5. (on an Android device): Client renders the Application GUI

The Client receives the application UI definition, parses the XML string and renders the application GUI using native Android controls.

Step 6. (on an Android device): User performs an action

When the User performs an action, for example clicks a button, the Client sends information about that action to the Server (in XML format).

In other words, the Client must ‘listen’ to all window events, and when an event happens, it must send information about that event to the Server.

Step 7. (on the Server side):

The Server receives the window event, and performs the exact same action on the Server-side application instance. If there is a visual change in the application GUI, the server will send a new XML data stream to the Client.
