You can create shortcuts to your apps on your smartphone. This is done by enabling the activity launcher. The launcher acts as an entry point for your app.
Background tasks can be held in the background
The activity launcher is the Android system’s way of controlling the running application. It’s a feature that lets the user quickly switch between tasks. For example, if the user launches a music app from the Start Screen, a new instance of the application is started. This allows the user to continue to use the music application while the background task is being handled.
However, when a task is launched in the background, the system will place the activity on top of the existing app’s task. As a result, when the user presses the BACK key, the previous activity will resume.
Alternatively, the system can place the task in the “foreground”. That is, when the system destroys the task, it will lose information about the state of the activity. If the system needs to recover memory, it will destroy the activity.
Aside from destroying the current activity, the system can also run the activity for a predetermined amount of time. Some examples include transferring data or synchronising data. These activities may be resource-intensive, meaning they will require additional power to run.
Launcher activities act as entry points into your app from the app launcher
Launcher activities are actions that can be launched in your Android application for a specific intent. For example, an email app might have an activity that shows a list of new messages. Likewise, a search bar in an app could be used for search.
Android applications are made up of many components, including widgets, icons, and UI elements. The home screen is where shortcuts to these applications live. The Android home screen can be customized for the user. Alternatively, the icon in the app launcher can be a shortcut to start the app.
When a user launches an app, the app icon opens the app in the foreground. However, this is not the only time that the activity is displayed in the app launcher. In other cases, the activity is added to the back stack, which shows the order of activities opened. This stack can be configured to hide apps from the launcher.
When an activity is launched, the system calls its onCreate method. You can define your own onCreate method or use the onCreate methods that are pre-written by the platform.
Setting the activity> element’s finishOnTaskLaunch to “true”
In Android 4.4 and later, the Activity element can be configured to have finishOnTaskLaunch set to “true” in order to preserve the activity’s state when the device restarts. It is important to understand that this option is not available to non-privileged applications.
The Activity> element can also be configured to have a drawable resource. This resource provides an extended graphical banner that is used by the system to represent your app in the home screen of the Android TV. However, this option should only be used by applications that have the CATEGORY_LEANBACK_LAUNCHERS intent.
The multi-window mode attribute can be set to either “true” or “false”. If the application is running in multi-window mode, the system will ignore the orientation attribute. Therefore, an app that is in a multi-window mode may have other apps open at the same time.
The FLAG_ACTIVITY_NEW_TASK flag can be used to create a new task. The same applies to the FLAG_ACTIVITY_MULTIPLE_TASK flag.
Lastly, the PersistableMode attribute can be used to control how the system handles an activity. This value affects the behavior of the root activity as well as any additional tasks launched from the activity.
Creating shortcuts for the apps installed on your smartphone
Activity Launcher is a simple, yet effective Android launcher, designed to create and manage app shortcuts. Using this app, you can create and launch apps directly, and even manage system tools.
The home screen of an Android device is where the shortcuts for the applications installed on the phone reside. By tapping the home button, users can reach the apps and widgets they use most often. You can also set up shortcuts for specific functions and activities. Activities such as sending messages, playing TV shows, and searching locations can be accessed via these shortcuts. This allows you to start common tasks more quickly.
In the Activity Launcher, you can use the submenu to change the look of your folders. This allows you to customize their icons, as well as the animation when a folder opens.
You can also add a text label to your shortcuts. You can customize their appearance by switching the background color and drop shadow of the text label. You can also edit the size of the icon.
