I am at a point where I need to detect if any of the hardware buttons was presses when the flutter app is in foreground or when it is open.*
For example, when someone presses a volume or another button (even if it is the power off one) I want to perform some action in my app.
I know that when a flutter app is open and I am looking at the app logs and I tap any hardware button is tapped the lops related to that tap is printed in the logs.
Like when I press Vol down Key Down Tap Detected related logs are printed in logs.
How do can I perform a function when any of the above specified action is performed?
New plugin called Hardware Buttons was released just a few days ago.
It supports volume button events and power button events, which seems like fits your need.
Maybe have a go with this?
You will need find the proper flutter packages to do so.
Any system level call needs to use the platform channel api
https://flutter.io/platform-channels/
Here is the repository
https://pub.dartlang.org/flutter/
Here is an example of a method channel.
https://github.com/flutter/plugins/blob/master/packages/device_info/lib/device_info.dart
Here is an example of a stream listener.

The stream listener wasn't really well documented when I tried to grab mic fragments.

Currently, the only way to close the notification is by pressing the stop button. But I wonder how can I wrap up the notification widget with a swipeable "thing". Can you tell me any package that would work on this or code that I have to wrap up a thing from the audio_service package?
The audio_service package publisher is - ryanheise.com
As a useful tip, the easiest way to search the entire documentation of audio_service to find an answer to some question is to navigate into the audio_service.dart file (which contains the whole plugin), and then search for the word "swipe". You will find this option on AudioServiceConfig:
/// Whether the Android service should switch to a lower priority state when
/// playback is paused allowing the user to swipe away the notification. Note
/// that while in this lower priority state, the operating system will also be
/// able to kill your service at any time to reclaim resources.
final bool androidStopForegroundOnPause;
And then inside the AudioHandler:
/// Handle the notification being swiped away (Android).
Future<void> onNotificationDeleted();
(You may find this easier to search than reading the online HTML documentation.)
What the above means is that you need to pass androidStopForegroundOnPause: true as a parameter to AudioServiceConfig and then if you want to handle any special behaviour other than the default (stop the service) when the user swipes away the notification, you can optionally override onNotificationDeleted in your own audio handler. There is no equivalent for iOS.
Note that it is not possible to swipe away the Android notification while audio is playing, but the option mentioned above will allow you to swipe away the notification from the paused state.
Hi I need to implement a functionality in my apple watch where when user swipes down will move from one module(InterfaceController1) to another module(InterfaceController2).And when user force touch menu should pop up and tapping on any button in the menu should present a model.
I am able to implement forceTouch menu option. But where as with swipe down to move to second module, i am not able to get any doc about this.
Please let me know if someone is aware of it.
Short Answer:
No, You can't.
Long Answer:
All WKInterface objects are proxy objects(aka Remote UI) that allows you to send queries to real UI Objects.
Reminds that the bundle that contains storyboard is separated with extension bundle. In sand-box concept, Your code that running on extension bundle can't access real UI Objects directly.
So there is no way to react against of user actions except that are available with interface builder(aka sentAction).
The best way I can describe this is the following. I have a poster gallery that has a bunch of images. The selected poster gets highlighted as the user moves back and forth through the gallery. I have the following code set on the poster gallery:
Gallery posterGallery = (Gallery) context.findViewById(R.id.moviePosterGallery);
posterGallery.setAdapter(new MoviePosterImageGalleryAdapter(context, key,
item.getCategory()));
posterGallery.setOnItemSelectedListener(
new MoviePosterOnItemSelectedListener(bgLayout, context));
posterGallery.setOnItemClickListener(new MoviePosterOnItemClickListener());
posterGallery.setOnItemLongClickListener(new MoviePosterOnItemLongClickListener());
What seems to happen is if you press the Remote on the vizio costar, both the Click and Long click events are being fired if you hold down the OK button. As in my case a dialog pops up when a Long click is received, but also the poster launches the video related to that to start playing which is part of the ItemClickListener code..
When testing the same code on a Nexus 7 tablet, only the long click is fired, not both. Is there a way to handle the long click correctly on Google TV. I'm using a vizio costar with Google TV 3 if that helps.
Also, if you move the mouse pointer over the item, and then hold down the - key on the front of the remote, only the long click event is triggered. It just seems to be related to the OK and how long that held down.
I looked at the following similar issue:
onListItemClick and onItemLongClick Google TV
but I already have the onItemLongClick returning true when it handles the event.
There is a quirk with the Vizio remotes. The OK button is not mapped to the right keycode. The Vizio remote sends KEYCODE_ENTER when OK is pressed when in fact it should be sending KEYCODE_DPAD_CENTER. This is what is causing your issue I think. If you try using AbleRemote as the input device you should be able to see it working as expected. Now to solve your issue you may have to go to a keycode listener if a keyboard is present and detect the key events on the posterGallery to fire off short and long clicks.
I'm working on a custom app for a client and am still relatively new to iOS development. The app involves setting reminders and I'm using UILocalNotifications. Now from my research the action on the notification will always run the app but I'm really hoping someone can correct me on that. Also from what I've read you are limited to the 'View' or 'Close' options. Ideally I'd love to have 3 buttons on the notification and not have to open the app to perform an action.
I'd like a 'dismiss' option, 'snooze' option, and an 'ok' option that dismisses the notification but runs some code in the background.
I came across a notification related question where somebody suggested opening the app with a modal view and presenting the options from there. Possible, just not as clean, I guess.
Any other ideas or is this what I have to do to achieve my desired functionality? If that's the case is there a way to close the app after I've selected one of my options from the modal view?
Thanks in advance.
That is not possible, as the notification is not created by your app but by the system, so you can't customize the appearance of the notification. (also in iOS 5, the user can choose to display the notifications as banners instead of alerts, which would hide any other button than the view and close button, if that were to be possible).
Secondly there is no way to close your app, as iOS is a user centric system, where the user takes the decision on whether to open or close app, and not the app itself.
I want to develop a program like button savior (which runs on top of a another app and we can press menu, back buttons on top of a running app). So user do not need to press hardware buttons to access menu, back functionalities.
I want to do the same but to do it I have to run a app on top of another app.
How can I do this?

Take a look at Robotium: http://code.google.com/p/robotium/
It seems to be doing what you want to do. You can take a look at the code and figure out how to do it.
Well i think that what you are looking for is creating something like Input Method (IME), there is a good tutorial to start with on Android Docs, another thing you can do is to create an activity which contains your virtual controller, distribute that as a lib and then if someone need it they can downloads and register your component into their project, something like what AdMobs does.
