The Basics: How do I Create Hello World on Android?
This lesson describes the very basic steps of creating an application that runs on Android via LiveCode. Screen captures and sample code are provided.
Introduction
The lesson bridges the gap between installing the Android development environment (covered in lessons: How do I Become an Android Developer on a Mac? and How do I Become an Android Developer on a PC?) and implementing the first LiveCode application that runs on an Android device. The code is very elementary and the steps are very detailed, focusing primarily on the mechanics of implementation and deployment.
Note: This lesson assumes that you have already installed and configured the necessary packages to begin developing software for the Android platform.
Open LiveCode and Create a new Mainstack
Open the LiveCode IDE and create a new mainstack by selecting File -> New Stack -> Default Size from the IDE panel. This creates an empty stack on which you will be implementing the application.
Create a Button
Drag a button (1) from the IDE Tools onto the new mainstack (2).
Change the Name of the Mainstack
Right click on the mainstack window you created to open a dialog window, then select Stack Property Inspector from that dialog. Change the contents of the Name field from Untitled 1 to Hello World.
Change the Name of the Button
Select the button you just dropped onto the mainstack window and the Property Inspector changes to display the properties of the button. Change the Name of the button from Button to Click Me.
Write the Code
Right click on the button you just renamed and select Edit Script. The Script Editor window opens, allowing you to write the code that is to run on your Android application. Add the following code into the editor window:
on mouseUp
answer "Hello World!" with "Ok"
end mouseUpThen select the Apply button. You have now implemented your Android application and are ready to launch it on an Android device.
Launch the Android Device Emulator or Connect a Physical Device
In this lesson we are using the emulator to simulate an Android device. Launch the Android emulator from your Android SDK and AVD Manager. Lessons: How do I Become an Android Developer on a Mac? and How do I Become an Android Developer on a PC? would have shown you how to configure and start your simulated Android device.
Note: The emulator needs to be running for LiveCode to launch your application.
Configure the Standalone Application Settings
Select File -> Standalone Application Settings ... from the IDE Panel. This launches the Standalone Application Settings dialog. Select Android as your target and ensure that the Build for Android tick box is selected. You should be able to use the default settings.
Select the Target and Launch
The last step is to select the deployment target from Deployment -> Test Target. You should be able to select the emulator that is already running. This enables the Test button that launches your application into the Android emulator.
Running the Hello World Application
Once the application has been launched and is running in the emulator, you can interact with your application. Try selecting the Click Me button to raise the dialog. Then select the Ok button to dismiss the dialog again.
so i went to development->plugins->and there is no revandriodplugin !!!!
so what now .. i want to see this thing run...
