So the other night when I finally finished the Sudoku app, I was curious as to how to go about actually pushing the app to the phone for testing. Little did I know just how incredibly easy such an endeavour truly was. Starting from absolute scratch, this is how you'd go about starting and testing your very first app on the DROID (it takes almost zero skill to do this, and as far as I know, there is zero chance of you accidentally screwing up your device, as it's a very simple Hello, World app): I'm at work at the moment, so it's gonna be a bit vague on some of the pre-done steps. I'll create a dedicated page with thorough steps later on. 1. Visit the official Android SDK site for the steps on configuring and installing the Android SDK and Eclipse IDE. 2. Go to the official Motorola page to download the necessary USB drivers to interface properly with your device. (I'd provide a direct link, but I acknowledge the fact that some users may have 64-bit systems, and you need to choose the driver appropriate to your configuration). You'll wanna go for the Motorola Mobile Phone USB Drivers (for Windows®), not the charging drivers. 3. Once again, visit the official Android SDK site for information on how to create your Hello, World app. Honestly, the app is painfully simple to create. It's little more than clicking File » New » New Project, and then selecting Android Project. Beyond that, the fields you fill out are... Code: Project name: HelloAndroid Application name: Hello, Android Package name: com.example.helloandroid (or your own private namespace) Create Activity: HelloAndroid Min SDK Version: 2 For the SDK version, you can choose anything from 1 to 6, really. The tutorial at the site was most likely written when they had 1.1 released, and they just never went back and updated it. Anyway, click Finish, and you'll have your new app framework created. 4. Plug in your DROID via the USB cable, and then click on your Menu button, click Settings » Applications » Development, and then check USB Debugging. This will set your phone into debug mode, and it'll catch your app when you run it from within the Eclipse IDE. 5. Back in Eclipse, right-click your project folder, and then choose Run As » Android Application. If you haven't saved it, it'll prompt you to do so, and within seconds, it'll launch the app on your DROID. Nothing too spectacular, really: just a readout saying, Hello World, HelloWorld!, or something to that effect. 6. Congratulations, you've just created and tested your very first Android app on your own DROID! If you have any questions on this, or need assistance, lemme know. I'll do my best to assist.
