I have to change existing app to an instant app.
While editing, there was a problem with bluetooth permission.
Does an instant app support Bluetooth?
Bluetooth is not yet supported by Instant Apps. Check the Instant App FAQS permissions and you will notice these are the supported features as of now:
BILLING
ACCESS_COARSE_LOCATION
ACCESS_FINE_LOCATION
ACCESS_NETWORK_STATE
CAMERA
INSTANT_APP_FOREGROUND_SERVICE only in Android 8.0.
INTERNET
READ_PHONE_NUMBERS. This permission is available only in Android 8.0 (API level 26).

I want my watch app to be identified by my paired iPhone.I am using CoreBluetooth Framework to implement this. I am transmitting bluetooth signals from my watch app and trying to receive the signal in my iPhone app. I am using the same concept as apple has shown in its sample code (https://developer.apple.com/library/ios/samplecode/BTLE_Transfer/Introduction/Intro.html#//apple_ref/doc/uid/DTS40012927) , the only difference is that my transmitter is the watch app.
Issue
I am unable to detect watch app in my iPhone. I have made sure that all of my hardwares are configured properly and I am configuring the Core bluetooth delegate methods properly. I also suspect if this method will be feasible with iPhone and apple watch.
All suggestions are appreciated. Thanks in advance
This is not possible because your WatchKit app runs as an extension on your iPhone and therefore all Core Bluetooth bluetooth signals are sent from the iPhone itself to itself.
Access to Core Bluetooth on Apple Watch lets your apps bypass the phone and connect directly with the Bluetooth in Apple Watch. Access Core Bluetooth to connect directly with accessories. And with Apple Watch Series 3, your apps can take advantage of built-in cellular and altimeter capabilities.
Please note, since watchOS 6 it's possible to use CoreBluetooth on watchOS.
Check for more informations this link "Creating Independent watchOS Apps"
Be aware there are still some limitations using CoreBluetooth in watchOS for example:
The minimum connection interval is 30ms instead of 15ms (for iOS devices).
The Apple watch can only operate as a central device.
The Apple watch can only be connected to two peripherals at one Time
The peripheral gets disconnected when the app goes into the background.
Maybe this will change when watchOS 7 is out.
I have the RX100-M3 camera, and it seems that some applications can be developed for it.
As far as I understand, the CameraRemoteAPI SDK can be used to develop Android or iOS applications. So is there a way to develop applications for the Sony camera?
I would like to develop a feature to be able to:
set the timer (from 2s to 2min)
select the number of shots (from 1 to 2000)
select the time between shots.
There is an existing "intervalometer" application but it is very expensive.
Camera Remote API SDK allows one to remotely control the supported Sony cameras including RX100M3 from any other device, by sending HTTP commands to the camera. The application you create can run from any
platform Android, iOS , Windows, PC, etc. You will have to connect this device to the camera over WiFi.
To get more information, please download the SDK, which contains sample applications and API documentation.

Is it required to have Apple Enterprise subscription to distribute iOS app through appcenter, or is there any method to iOS device (iOS 7.1) accecpt app from it with standard subscription? I tried everything but get error (cannot connect to ...) when i press download.
All applications managed through the Application Center must be packaged for "Ad Hoc Distribution".
With an iOS developer account, you can share your application with up to 100 iOS devices.
With an iOS enterprise account, you can share your in-house application with an unlimited number of iOS devices.
See iOS Developer Program and iOS Enterprise Program for details.
i wanna test my game that uses google play services api(for realtime multiplayer). But i don´t have an android phone or tablet, i only use the emulator.
Is there a specific model of phone that i should buy to use google play services or will it work on any android device?
On emulators, there´s a "target name" called google APIS, so i was wondering about the device.
I have already made my game work on emulators, but even of ButtonClicker example, there´s a delay on the timer on one of the emulators and not on the other. Maybe i should try with a real device?
It will work on any Android phone (not Android compatible). Avoid devices like the Kindle Fire that are compatible, but not actually Android. If it has the Google Play app and it's running Ice Cream Sandwich or higher, you should be set.
The Nexus devices tend to be developer favorites, as they have no customization from carriers or manufacturers and are fairly cheap. Developer Editions would be a good alternative.
Is it possible to transfer files between a Mac app and a iOS app? I want to transfer files that are in the documents directory in my iOS App to my Mac App via Wifi, how could I do it?
Well, as of iOS 5 onwards, there's iCloud. Since that's still under NDA, I'll just have to point to the relevant documentation and let you read up on your own.
If not, I'd consider using the fabulous Dropbox APIs. This does require your users signing up for a Dropbox account, but then you get automatic two-way syncing between their Mac (or PC) and their iOS devices.
Failing that, there's always Bonjour. Properly configured - and it's not super easy, there is a bit of CFSocket or BSD socket work that you need to do - Bonjour will discover any services on the local network, Mac or iOS.
