• Uploading and using media files in App Inventor • Playing and looping sound files • Arranging and placing user interface elements where you want them In the previous chapter, you walked through the process of creating your design goals, primitives, and process. in this chapter, you take all of that from the previous chapter and put it into play. I also walk you through several complex algorithms. Take special note of the method for placing and centering user interface elements on the screen. You need to reuse this method for almost any project you create. Creating user interfaces in App Inventor can be frustrating until you master the method of using invisible padding elements to adjust visible elements on [...]
Installing the android usb driver is the #1 priority if you ever want to access your phone through a computer, be it to transfer files or executing commands. This could lead to a lot of confusion and headaches if you fail to do this process.
Note: Newer versions of windows(vista and win7) will automatically install them as basic mass storage devices. You do not want this!!!
Firstly download the file android_usb_windows and unzip to your computer. Go enable debugging on your phone. (Settings->Applications->Development->USB debugging).
A window should pop up whenever you plug your phone into your computer, asking for you to install the device. Select “browse my computer to install driver software” option. Follow the steps to update the driver and include the android_usb_windows in your search when given the check box.
• Creating an android application with multiple screens • Getting data out of your App Inventor android application with e-mail • Using ActivityStarter to start other Android android Android application One of the questions App Inventors ask most often is, “How do I get data out of my android application?” in this chapter, you build an android application that takes user data and e-mails it to a given address. This is a good method for gathering field data and storing it elsewhere. In a later project, you see how to use the TinyWebDB component to get data in and out of your android Android application. The e-mail method you learn in this project could be used to send data to [...]
