I am in need of monitoring the camera hardware in android phone for an application i am building. I want to get an alert every time the camera hardware is accessed. Is there any possible way for this....?
You can set up a BroadcastReceiver that will receive any camera button presses if that's what you want to do.

I'm building a recording application. I want to show notification when other app is using mic and we are not able to record the audio from our application.
Example: There is zoom call going on and we cant record the audio till that zoom call get's over at that time I have to show pop up in my application that unable to record
How can I check if the device is a touch device or a mouse device?
Using kIsWeb is not sufficient because if using web version of the app on a mobile device kIsWeb returns true, but I need it to return false because it is a touch device.
Checking the platform doesn't work either because if using web version of the app on an iOS device for example returns false for iOS platform check.
Use case - I have two different types of video players for my app. One is suitable for touch devices (you tap to show and hide controls) and one is suitable for mouse devices (controls show when you mouse into the player and hide when you mouse out).
Youtube has the same idea. If I use the youtube app or website on my iPhone I get touch controls. If I use the youtube app or website on my iPad Pro I get touch controls. If I use the youtube website on my Mac I get mouse controls at all screen sizes (even mobile screen sizes).
So I guess I really just need to know platform on the web. I can get platform if not on the web.
Great question #jwasher! I had the same issue - a touch and swipe based UI that was great as a native mobile app, great as an single page web app (SPA) on mobile web browsers, but that was weird and clunky for mouse based interactions when the SPA was used in a desktop web browser.
The solution I have settled on is to wrap sensitive widgets in a MouseRegion (https://api.flutter.dev/flutter/widgets/MouseRegion-class.html) to detect mouse activity at runtime, then reacting by augmenting the UI with buttons to provide a mouse focussed way of triggering actions previously only linked to touch triggers.
You could use this to "mouse-enable" individual widgets, or you could wrap the whole app in a MouseRegion, trip a state field when activity was detected then rebuild the widget tree in a substantially different way for point and click users.
This strategy may incur some minor complexity/CPU overhead on devices that will never have a mouse attached (like a smartphone), but the solution will be more flexible than a build or configuration time capability determination. If a user starts the app on a tablet, then puts it in a stand and attaches a bluetooth mouse - it will react appropriately.
A device isn't "a mouse device" or "a pointer device". Events have an input type--see Pointer event.kind--but not the whole device. A laptop can have a touch screen, and a tablet can have a stylus or external mouse; an app running in those environments can receive both types of event.
Without knowing what you are trying to accomplish with this classification, is hard to advise on how to accomplish it. Trying to style your UI based on a guess of the primary interaction mode, for instance, is a completely different problem than reacting to a mouse event differently than a touch event.
I'm thinking to start in raspberry world, in my case, with Windows IoT.
I want to assemble the raspberry with a touch screen and i doubt about a concrete feature:
When my app need to show an alert, How i can wake-up the screen? (i supose that the screen is in sleep mode by tiemout or similar)
And, when i want to wake up the screen to manage the system, Can i handle the touch events when screen is sleeping? The screen wake-up automatically when i touch it? I don't want use keyboard or any other input method except the touch.
Is this scenario possible?
Thanks
I am working on Audio related project. I am playing audio, in both case, either my app is active or suspended. I am stuck here, when I play audio and lock my iphone, when I double click on home button, there appears the player controls. I try to play/pause may audio, without unlocking the iphone same as in default ipone/ipod application. Is it possible? If yes then feel free to help. Thanks in advance.
Use Remote Control events
Remote control events are any event received for the purpose of controlling media. eg iTunes pause/play/next/previous buttons available from double-tapping the home screen button, or remote-control events from play/pause buttons on headphones.

I want to build an alarm application for iphone. I want to ignore iphone device state and volume buttons state. I want to play sound anyhow in full volume and also want that user cant modify volume using iphone hardware buttons while sound is played. Does anybody know how to implement it? Please post the code here.......
Thankx in Advance.......
This is not possible (without jailbreaking).
You cannot force the iPhone to change its volume or intercept the hardware buttons. Also you cannot "ignore device state", as you cannot run background apps. So if your app is not running you can't execute any code
