I need to know that another app by using Settings.ACTION_CAST_SETTINGS started casting on the phone. When the user enables casting by this flag on an Android phone, a status bar icon will show that casting is enabled.
I tried to figure it out by using MediaRouter, but it didn't work properly.

At least for iOS, apps like Spotify, Hangouts, and Google Maps have a way of showing that they're still active when in the background (when you temporarily leave them to check a different app, etc.). This typically appears as a thicker status bar in iOS.
Other variants:
What is this bar called, and is this possible to implement for Android? I have a video chat app (in both Google Play and App Store) that uses TokBox (essentially WebRTC), and it renders this bar already for iOS when backgrounded, but not Android.
The consistent way to indicate an ongoing phone call in Android is using a notification. The Android phone app also uses a notification in this scenario:
To prevent the user from dismissing this notification, you can use the FLAG_ONGOING_EVENT or FLAG_NO_CLEAR - see https://developer.android.com/reference/android/app/Notification#FLAG_ONGOING_EVENT
On iOS, you might want to set a specific Audio Mode and Audio Category to get the right status bar look.
See https://developer.apple.com/documentation/audiotoolbox/audio_session_services/1618405-audio_session_modes
and https://developer.apple.com/documentation/audiotoolbox/audio_session_services/1618427-audio_session_categories
Further, the Background Audio capability is required - otherwise, your Apps audio session will be stopped after moving it to the background.
To achieve an even more consistent user experience, you might want to integrate the iOS CallKit or the Android ConnectionService, see
- https://developer.apple.com/documentation/callkit
- https://developer.android.com/reference/android/telecom/ConnectionService
It can be implemented in Android by using a notification and adding a flag FLAG_NO_CLEAR
This is a link where this is explained pretty clearly
I got the plugin to work. Its great, but I am not an android user neither have an android to test it with.
With what I got to see from the emulator, notifications do not show when the app is open. It plays a sound and add a bell icon on the status bar. Is this the default behavior? My app wont be scheduling any tasks for the future, it will receive some info via web sockets that I would like to explicitly show to the user. I was expecting something like a ios banner to pop of the screen. Is this possible?
Since Android Lollipop, the user can hide notifications of an application from Android settings.
I'm writing a parental control application and I'm searching for a way to disable this functionality.
Indeed, I want notifications to be always displayed, even if the child doesn't want to see them.
I saw that on tablets (not on phones) we can create a specific profile to block access to the settings app, but I don't want to lock the settings app, and the trick needs to work on phones too.
I also looked in manifest file to see if an option was there to explicitly enable/disable this but I found nothing.
Please note that my app does have admin privileges.
After hours of head scratching and hundred of coffees, nothing came to me from Android developer website or any other website, I'm desparated.
So finally, is there a way to disable the possibility to hide notifications in Android Lollipop?
Disabling the ability to hide unwanted notification would be undoing what that feature is. As far as I know there is no way to do that.
EDIT:
However - there is an broadcast send after each settings change (WiFi turn on / off etc.). Some settings blocking apps are using this to revert changes made before entering password - maybe there is an intent that does the same for hiding notification.
I am working on a control-based (V2.0) SW2 app. Is it possible to set the badge-number (i.e. the notification counter) on the icon in the application view used in a notification-based app? I do not need anything else from the notification API, I just want to be able to set the badge-number and removing it after the user opens the control-based app.
Thank you,
Andrej
Unfortunately that is not currently possible without using both the Control and Notification APIs together. If you use both of them in your extension you may be able to achieve something similar to what you want but with the limitation that the extension will always start in Notification mode (this is a bug in the current implementation) so you wouldn't be able to go straight into the Control part of your extension.
In recent versions of Android it's possible for devices to either have software or hardware buttons. I'd like to find out which is the case for the device my app is running on.
Some background information: It is possible to hide the softkeys as they are displayed on the screen but if you do this they automatically get shown if the user touches the display which is perfectly fine. Now if you do the same on a device with hardware keys the first touch still gets caught by the system like as if it would show the softkeys again but as there are none, nothing happens and the touch event does not get passed to the app.
You could use ViewConfiguration.hasPermanentMenuKey(), to check for a menu key.
For the Keyboard-question try
getResources().getConfiguration().keyboard
that gives you one of the following:
KEYBOARD_NOKEYS
KEYBOARD_QWERTY
KEYBOARD_12KEY
check for KEYBOARD_NOKEYS.
