6. The next screen is used to confi gure the directory of Android SDK. Only the root directory ofthe different versions of Android platforms is required.Note: The path of the SDK is stored for all the forthcoming projects.Go to the next screen.7. The next screen allows you to choose the device that will be used to develop yourapplication.Caution: this screen is important because the size of your windows will depend on this choice.If your device is connected, select "Other" in the proposed list and go to the next screen.If you have no device, choose one of the devices proposed in the list ("Samsung Galaxy S II"for example).Go to the next screen.8. If you have chosen "Other", the screen for detecting your device is displayed.My first windowOverviewThe fi rst window will allow the user to display a welcome message via the "Display" button.You may think this is too basic, too simple, but we recommend that you create this window. You maybe surprised by how intuitive and how easy it is to use the editor of WinDev Mobile. Furthermore,this window will allow you to discover concepts that are fundamental for the rest of this tutorialand to see the entire process for developing an Android application with WinDev Mobile.Creating the window To create the window:1. Click among the quick access buttons of the WinDev Mobile menu:2. A window shaped like a wheel is displayed. This window is used to create all the elementsthat can be associated with a project.3. Click "Window". The wizard for window creation starts.4. Select "Blank" in the list of windows displayed on the left. In the list of skin templates foundon the right, the "ActivAndroid 2" skin template is selected by default. You can choose anotherskin template proposed in the list.NoteThe skin templates allow you to quickly create outstanding interfaces. A skintemplate defi nes the style of the window but also the style of all the controls thatwill be used in this window. No ugly interface anymore.5. Validate. The window is automatically created in the editor.Click the "Click here to automatically detect the device" button. The characteristics areautomatically updated. Go to the next screen.9. In the left section of the wizard, click "3-Charters". This step is used to defi ne theprogramming charter. Don't modify the suggested options. Go to the next screen via thearrows found at the bottom.10. This step is used to defi ne the style book. Select "ActivAndroid 2".11. The other wizard steps not being important for our fi rst project, click "6-End" in the leftsection of the wizard.12. Click the validation button at the bottom of the wizard. The project is automatically created.WinDev Mobile displays the different possible actions.13. Click "WinDev Mobile editor".30 Part 2: Android applicationPart 2: Android application 31
Save the window by clicking among the quick access buttons. When the fi rst backup isperformed, a specifi c window is displayed. This window proposes to enter:• the title of the element: enter "Welcome". In our case, this title will be displayed in the titlebar of the window.• the name of the element is the name of the window. This name will be used in programming.By default, this name includes "WIN_" that corresponds to the programing charter and"Welcome" that corresponds to the title of the window.NoteLet's take a look at the window name proposed by WinDev Mobile: this namestarts with the letters "WIN_". This prefi x is automatically added because theproject uses a programming charter.The programming charter is used to defi ne a prefi x for each type of object,allowing you to quickly identify the element handled:• a window starts with WIN,• a button starts with BTN,• etc.If you don't want to use this charter, all you have to do is disable it: on the"Project" pane, in the "Other actions" group, expand "Charter" and uncheck "Usethe charter" .• the location that corresponds to the fi le name created for the window. The window is a fi lewhose extension is "WPW", saved in the project directory. Click the green button to validate.Displaying a messageYou are now going to create a button used to display a message.To create the "Display" button:1. On the "Creation" pane, in the "Usual controls" group, click . The button appears increation under the mouse.2. Move the mouse in the window toward the position where the control must be created (atthe top of the window for example). To drop the control in the window, all you have to do isperform a new left mouse click.3. Perform a right mouse click on the control that was just created. The popup menu of thecontrol is displayed. Select "Description" from this popup menu. The description window of thebutton is displayed.Modify the characteristics of the control by entering the following information:1. Name of this control: "BTN_Display".2. Caption of this control: "Display"Validate the description window of the control (green button). The control is displayed in thewindow editor.We are going to display a message in a dialog box (a small window proposed by the system).To do so, we will be using our fi rst WLanguage function: Info.NotesWLanguage is the programming language supplied with WinDev Mobile. It's a 5thgeneration language (5GL) that uses highly sophisticated commands.1. Select the "Display" button with the mouse: all you have to do is click it.2. Display the popup menu of the control (right mouse click).3. Select the "Code". This option opens the code editor of WinDev Mobile, in which all theWLanguage statements can be entered.4. Enter the following code in the "Click BTN_Display" process:Note about the assisted input: As soon as the fi rst two characters are typed, WinDev Mobileproposes all the words of the WLanguage vocabulary containing these characters. The aideddevelopment is very a powerful feature. No more mistake when typing the name of an element:the syntax errors are reduced to a minimum. All you have to do is select the requested word andpress [Enter] to validate. You can focus on the algorithm.32 Part 2: Android applicationPart 2: Android application 33
