  Introduction Review of literature is a very important exercise which researchers as well as students at both undergraduate and postgraduate levels cannot shy away from, as it identifies and summarizes research and theories that are relevant to their area of interest, and as well sets good foundation for research or theses writing. In this article, we will consider some aspects of literature review such as its meaning, its significance, what it entails, steps to take in writing a good literature review, and some of the things that we need to avoid while reviewing literature. Meaning of literature review Let us first break down the key concepts and see what the dictionary has for us as per the meaning of ‘Literature’ and ‘Review’.

  Introduction: In Android application development, buttons could be programmed to perform some actions (such as navigating to another screen, showing toast message, closing the app, among others) when the user taps or clicks on them. In this article, we will learn how to make a button to perform the action of displaying an alert message to the user. This would be achieved using a composable function called AlertDialog. Note that we will be demonstrating this with the 'Click Here to Proceed' button located inside the ‘DemoScreen’ composable function in our 'Demo One' Android project from my previous article. Demonstration: First, we will open the 'Demo One' project. ‘Demo One’ project is now opened as shown in Figure 1. Figure 1 Next, above the button composable in our ‘DemoScreen’ composable function, we will define a mutable state variable, set its value to ‘false’, and store it with the name 'showAlertMessage' (as shown in Figure 2). Note th...

  Introduction: Every Android mobile application usually comes with unique app icon associated with it by the Android Developer. An app icon visually represents a mobile application on the screen of user’s device, or in any app store, for example, Figure 1 shows app icons for various applications on the screen.   Figure 1 It is therefore a good idea to have an image designed for the Android application that you are building. The dimension of the app icon could be 512 x 512 pixel. You can then add the app icon to your Android project to replace the default launcher icon associated with app projects in Android Studio. Demonstration: In this demonstration, we will be replacing the default icon with our app icon (as in Figure 2).   Figure 2 To add your app icon to your Android project, take note of the following: First, ensure that your app icon image has been designed and ready for use (for example, Figure 3 shows an image named “my_app_icon”- designed for “Dem...
