== Step 5 - Start Enter the Project Name and ensure the project specific JRE selected is BlackBerry JRE.  Click next ==== Step 6 - Click Next and leave the default Java settings as it is ==== Step 7 - Click Next and select an Empty Application to start developing ==== Step 8 - Click Finish and on the Application Tab, enter the Title for your application ==== Step 9 - Expand the file structure in the Package Explorer window and examine the structure  already created for you ==== Step 10 - src folder will contain your package(s) and all your application code files. ==== Step 11 - res folder is the resources folder which can contain additional resources your app might  use - like images, audio or video files, or the app icon ==== Step 12 - Expand your src folder and double click the .java file to begin editing ==== Step 13 - It will look like it does in the screenshot below. It will have to be edited to make it  the start screen where you app starts ==== Step 14 - This is done by extending UiApplication class, which will co-ordinate the screen that is  currently on top of the screen stack ==== Step 15 - We have also added some code to create a new instance of the application and make the  currently running thread the application's event dispatch thread in the main function ==== Step 16 - In the constructor of the App's main class file, we push a new screen onto the top of  the screen stack ==== Step 17 - The name of the new class created, which will be the first screen of the app is  specificed int he pushScreen method ==== Step 18 - Right click the package, and create a new Class, called MyScreen ==== Step 19 - MyScreen will be the first screen of the app and here we can configure a screen title  and anything else we want to start the app with ==== Step 20 - In this tutorial, we create a button, defined as an instance variable of the MyScreen  class ==== Step 21 - We set the current class to be the listener for any changes in the state of this button  and assign it a title ==== Step 22 - The button is added to the screen, which is a UiApplication object ==== Step 23 - In the field changed method, we push another screen into view when the button is pressed  ==== Step 24 - The LocationTracker class is pushed into view and so it also extends the MainScreen  class ==== Step 25 - To get the location of the user in the LocationTracker class, we need to have a class  that gets the users location ==== Step 26 - The MyLocationListener class implements LocationListener, so the class can be notified  as the users location is updated ==== Step 27 - The locationUpdated method gets the latitude and the logitude of the user and saves then  in two instance variables of the MyScreen class ==== Step 28 - In the LocationTracker class, we define some RichTextFields to output the collected  value of the latitude and longitude ==== Step 29 - We also create a BitMap object and configure its weight and height using the methods  defined in the BlackBerry docs ==== Step 30 - The BitMap object, SeparatorField object and RadioButtonField objects are added to the  screen ==== Step 31 - We add a new button that will process the results of the radioButtons ==== Step 32 - The button's field change listener method is coded to alert the user based on their  radiobutton value selected ==== Step 33 - Import all required packages and resolve anyother warnings suggested by Eclipse==== Step 34 - Once all errors are resolved, Click on Run, go to Run as and Go to File > New > then BlackBerry Project Simulator  ==== Step 35 - Expand on the apps in the simulator, and select the app just created ==
