We are going to make a very simple layout xml for our activity, that only consists of a LinearLayout that contains the necessary textviews and buttons. You can see the structure of the project: Figure 7. It will also be created a fragment layout xml, that we are not going to use in this project and you can remove it if you want. xml file for the layout will automatically be created in the res/layout folder. You have to specify a name for the new Activity and a name for the layout description of your app. Select the “Blank Activity” option and press Next. We will use the default icon of android, so click Next. In “Configure Launcher Icon” window you should choose the icon you want to have in your app. The new created activity will be the main activity of your project. In the next window, the “Create Activity” option should be checked. We will use the following tools in a Windows 64-bit platform:įigure 2. However, in this tutorial we are going to see how to use a TimerTask, and we will make an application that will handle with recurring events. You can also learn more about Android Handler in the JavaCodeGeeks Android Handler Example. This is why Handler is very common amongst Android programmers and projects. Literally, Handler is a native android class that handles memory leaks problems in a better way than Java-Timer does. In Android, Timer and Handler can be used for pretty much the same reasons, and in the same way. This may result in a series of bunched-up runs (one launched immediately after another) if delays prevent the timer from starting tasks on time. With fixed-rate execution, the start time of each successive run of a task is scheduled without regard for when the previous run took place. With the default fixed-period execution, each successive run of a task is scheduled relative to the start time of the previous run, so two runs are never fired closer together in time than the specified period. We will use the abstract class TimerTask. In this example, we are going to see, how a java.util method, can help us deal with timer recurring tasks that are scheduled with either a fixed period or a fixed rate on Android.
