In this article we will glimpse across the many ways possible of how to make a app free of charge, without any prior programming knowledge or other demanding conditions. Just sit back, relax and let this guide fill your cortex with inspiration, or in medical terms – endorphin secretion.
As a disclaimer, the following tutorial covers Android Jelly Bean, as well as the API level number 17. The app in mind will convert miles per hour to kilometers per hour, and of course, will be made up entirely from scratch, without any prior coding experience whatsoever (but little bits of XML and Eclipse knowledge won’t hurt either).
First, you need to install the famous Android SDK and IDE tools; there’s a bundle package for that, so head on to Google, type ‘Android SDK development tools’ and let the magic of the browser do the rest. Then click on the link provided, check if it’s virus-free and continue with your plan – to make a app free – the best one on the market. Now you can start Eclipse and follow on.
Making a virtual machine
To make everything happen on your desktop or other stationary computing machine, you need an emulator or a virtual machine that will run things for you, like debugging, testing and cover other important aspects of building apps. Of course, with everything being virtual, there’s slim chance of anything going wrong – if for some reason that happens – make sure you uninstall all software you injected before and install it again. When that’s done, go to the navigation toolbar and open an executable file under the name of ‘Android Virtual Device Manager’. Click the button that says ‘New’ to make a virtual machine and make sure you enable the ‘Use Host GPU’ option. With the same enabled, the GPU will render the AVD with light speed – if set correctly.
After that continue on your path to make a app free and start the AVD executable. In the AVD section, open a new file and make an Android Application project, with all parameters involved, and even those that are not included. Choose the minimum required SDK, the Target SDK, the compiler and your app’s theme. After that (or before that, it depends on your point of view), choose a name for your app, a name for your project and a package name. By clicking next, the window will change to a ‘configure project’ interface. Here you can create your custom launcher icon (if you happen to be the undiscovered artist), the app activity, as well as marking the project inside your app library, or create your project in a controlled workspace folder or subfolder. You can also choose to add your project to a working set, or just visit Appsbar and make your app on the fly.
The Launcher Icon
This icon, as stated above, is configurable in both the artistic and the programming way. You can change all attributes of your launcher icon, or do them one at a time while you make a app free. Now, the interchangeable things: you can change the foreground, or upload an image, clipart or even text if you desire to do so; afterwards comes the trimming of a potential blank space if it happens to surround your launcher icon; then there’s the additional padding (with crop and center as modifiable parameters), square, circle or other shapes and of course, the background color. When all of the above is done, click next and wait for the activity to happen.
