Facebook Messenger Minimum Android Version

[Gabriel Litke]

Sometimeswe require our app to show some content on the main screen irrespective of the app running in the foreground, this process is known as drawing over other apps. There are many apps that use this functionality to provide maximum features with minimum screen coverage. This also enables the user to do multitasking. For example, the chat bubble of Facebook Messenger, Mobile Over Usage notice of YourHour App, Voice Command of Google, and many more. We can create similar functionality using the WindowManager interface provided by Android SDK.

The Android WindowManager is a system service that controls which windows are displayed and how they are arranged on the screen. When you launch or close an app or rotate the screen, it automatically executes window transitions and animations, among other things.

In order to draw over other apps we require, android.permission.SYSTEM_ALERT_WINDOW permissions and for android with API version > 23 we need to ask for this on runtime. android.permission.SYSTEM_ALERT_WINDOW allows an app to create windows using the type WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY, shown on top of all other apps.

Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.

I bought this ***** called Galaxy Watch 4, because I thought if it has android then my regular apps will work on it. Just to realize that basically a 30 EUR Chinese noname fitness band gives you more than this useless pieces of *****. Because the 30 EUR chinese noname fitness band usually shows your notifications from Facebook messenger, Signal, Instagram, but this sophisticated piece of Samsung technology is apparently incapable of doing that.

Does someone have any idea if there is any way to get your Facebook messenger or Signal notifications on it? Or I will return it and get the 30 EUR Chinese fitness band, because that seems smarter than this thing.

Still I cannot pickup calls from FB Messengers, or Signal. Only Whatsapp calls can be picked up through the watch. If the notification arrives in time, but usually there is a delay of 5-10 minutes. Despite of the fact that my galaxy wearable app is on all the time and ate up 10 percent of the battery of my S21 ultra.

If yours is anything like mine the notifications did not come whilst wearing the watch but when you removed the watch the notifications all arrived.... So now my watch is in the service center either being fixed or replaced...

My Galaxy Watch 4 "Classic" has worked out of the box with FBmessenger. Even the messenger calls. My wife's Galaxy Watch 4 has not worked even after the options were selected. Would it have something to do with mine being the large Classic version?
