Is there any way of reliably detecting if the home button has been pressed in an android application? Failing that, is there a robust way of telling what caused an activity to go into onPause?
One suggestion I have seen is to override onPause and call isFinishing but this will return false when pressing the home button just as it would if a new activity is starting so this fails to distinguish between the two. So it would seem that contrary to popular belief, you can in fact listen out for the home key.
Worryingly, you can return false and have the home key do nothing. Update : As expected, there are some side affects with this - it seems that embedded videos and google maps are not visible with this mode enabled. According to the documentation, the onUserLeaveHint method is called when the user clicks the home button OR when something interrupts your application like an incoming phone call.
This is built into the system to prevent malicious apps that cannot be exited. Unfortunatelly I didn't manage to change order of calls of onPause method of the starting activity and onResume of the started actvity when Activity. Override onUserLeaveHint in the activity. There will never be any callback to the activity when a new activity comes over it or user presses back press.
This will detect the home key click. This method is called right before the activity's onPause callback. But it will not be called when an activity is interrupted like a in-call activity comes into foreground, apart from that interruptions it will call when user click home key.
It's a bit hacky, but given the reasons that interception of the home button is prevented it has to be. I had this problem, and since overriding the onKeyDown method didn't accomplish anything because of the underlying android system didn't call this method, I solved this with overriding onBackPressedand I had a boolean value set there to false, because I pressed back, let me show you what I mean in code:.
So the reason why this worked is because the only way to navigate outside this activity is by pressing back or home so if back was pressed then i know the cause wasn't home, but otherwise the cause was home, therefore i set the default boolean value for homePressed to be true. However this will only work with a single activity instance in your application because otherwise you have more possibilities to cause the onPause method to be called.
This will tell you that your Application is going to the background. An option for your application would be to write a replacement Home Screen using the android.
HOME Intent. I believe this type of Intent you can see the home button. Since you only wish for the root activity to be reshown when the app is launched, maybe you can get this behavior by changing launch modes, etc. Tasks and Back Stack is a great resource for fine-tuning this sort of behavior.
It's a bad idea to change the behavior of the home key. This is why Google doesn't allow you to override the home key. I wouldn't mess with the home key generally speaking.

Today we will show you how to use a free app called Home2 Shortcut to choose the action that happens when you double-press the physical Home button on your Android device. When you double-press the Home button, you can open any app installed on your device or various shortcuts or plug-ins. If you have a device with these buttons, you can set up shortcuts for them too.

You can adjust the speed of the double-press, or double-tap, interval. We recommend you try that first to see if it works for you. Next, you need to choose the Home application you always use.

Samsung, along with many other manufacturers, is leaving the home button by the wayside as the ever-increasing displays gobble up more and more of the smartphone's front panel. The stylish Samsung Galaxy S8 was the first flagship from the Korean company to ditch it, and now even lower-range devices in the A-series follow suit. Nonetheless, the physical home button still has its fans, and we'll show you how to get the most out of it.
On older Galaxy devices, a single tap of the physical home button will bring you to your home screen, a double-tap launches S Voice, and long-press launch Google Now with a long press. Happy customizing! What other cool modifications have you made to your Galaxy? Tell us about them in the comments.

You are correct, Sir. So my s5 when i hit the sleep button on the side to power up screen. The screen stays black. The screen still has full function. I can feel phone vibrate i can unlock because i have swipe pattern but can not see screen. Sometimes it works perfectly fine. An the other half the time it dose wat i dose wat i described early its not the brightness, i also did all updates. Took to service provider tech. Please help anyone else had this problem.
Screen buttons hide quite well in Android. It's certainly not a problem I've had with buttons interfering with games. My home button on my great Samsung Galaxy S5 is now mostly redundant as I use a great app called floating Toucher, it's a super charged version of the Samsung app "Toolbox". It allows me to lock the screen, flip between regular used apps and quick settings and has a home screen button. I have also changed the settings to allow "Air Wake up" settings - Device - accessibility - dexterity.
This allows you to wake up my S5 by waving my hand over the phone. I only use the home button on rare occasions that the light sensor fails or microphone doesn't pick up Google now request. Though now I can set up the home button im going to have to play around see if it's time to start using it again. Android phone makers need to abandon the lame ideas of apple and adopt the smooth slick screen of what Android itself is designed for.

The two options below are enabled so shouldn't it go to the home activity automatically? As other people have said, the behaviour doesn't happen automatically - you need to tell it where to go. However, I need to add another answer, as the current answers are all breaking Android design guidelines - Back! See the documentation.
Which will take you to the parent activity, rather than just go through the back stack. I've also added the Intent. Flag to clear the back stack, it's a useful one to have when going to a home activity and can stop the back stack getting in a muddle when your users are using the 'Up' button.

I can't count the times a client has insisted the home button to function as back because it needs to be consistent with the flow of the iOS version of the app It is not true, that generally Back! In the exact same linked docs it says: Navigating to screens with multiple entry points: Sometimes a screen doesn't have a strict position within the app's hierarchy, and can be reached from multiple entry points—such as a settings screen that can be reached from any other screen in your app.
In this case, the Up button should choose to return to the referring screen, behaving identically to Back. I believe this can be a quite common case Till I would disagree. The very fact that Navigating to screens with multiple entry points is listed as a separate item indicates that it is a special case, not general behaviour.
As such, overriding onBackPressed should be the exception and yes, is occasionally valid rather than the rule - but all of the other answers treat this as the common solution, hence me stressing this point in my answer.
An app that commonly has screens without a strict position within the hierarchy would be hell to navigate. If this occurs often within your app, I would suggest redesigning your UI flow.One of the most attractive aspects of Android is the fact that you can customize it as you like.
