What is an Accessibility Service?Īn Accessibility Service assists users with disabilities in using Android devices and apps. This codelab shows you how to create a very simple accessibility service. An accessibility service can communicate to the user on the application's behalf, for example by converting text to speech or providing haptic feedback when a user is hovering on an important area of the screen.
RootView.findViewById(R.id.content_button).Accessibility services are a feature of the Android framework designed to provide alternative navigation feedback to the user on behalf of applications installed on Android devices. Here it goes: private val windowParams = WindowManager.LayoutParams( In the short source code sample above, we called addView with the second parameter being windowParams of type WindowManager.LayoutParams. WindowManager.addView(rootView, windowParams) Val windowManager = context.getSystemService(Context.WINDOW_SERVICE) as WindowManager
Fortunately, it allows us to add and remove views directly, and if we add them with correct parameters, we have our floating windows! // Obtain WindowManager WindowManager is an interface that the app can use for communication with the window manager.Īnd the window manager on Android handles everything you can see on the screen. In this article, I will teach you how to show the actual floating window over other apps. I received feedback from tens of thousands of users and see various issues on different phones with different Android versions.īefore reading this article, it’s recommended to go through Floating Windows on Android 3: Permissions.
It’s sometimes tricky, and I spent months reading documentation and Android source code and experimenting. After 6 years of the development of the app, I know a bit about it.
I’m the author of Floating Apps the first app of its kind on Google Play and the most popular one with over 8 million downloads. Have you ever wondered how to make those floating windows used by Facebook Heads and other apps? Have you ever wanted to use the same technology in your app? It’s easy, and I will guide you through the whole process.
