Welcome to Ranch, Alex Soto Bueno & Jason Porter

Intent not working after applied Lock Task Mode.
    @SuppressLint("SetTextI18n", "SourceLockedOrientationActivity")    override fun onCreate(savedInstanceState: Bundle?) {        super.onCreate(savedInstanceState)        binding = ActivityMainBinding.inflate(layoutInflater)        if (Build.VERSION.SDK_INT >= 27)            setShowWhenLocked(true);        else            window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);        setContentView(binding.root)        binding.bluetoothConstraintLayout?.setOnClickListener {            Timber.i("efefef")            val intentOpenBluetoothSettings = Intent()            intentOpenBluetoothSettings.action = Settings.ACTION_BLUETOOTH_SETTINGS            startActivity(intentOpenBluetoothSettings)        } }
Before that, bluetooth setting able to open, but after screen locked, it only display "efefef", it did not open bluetooth setting.

Our app have connected a Bluetooth media device. We place this code in onCreate, but why the size returning empty?
We did add all the Bluetooth permission.

val bluetoothManager = this.getSystemService(BLUETOOTH_SERVICE) as BluetoothManager val size =  bluetoothManager.getConnectedDevices(BluetoothProfile.GATT) print(size)  // it prints []

Chapter 9 covers Collections and Generics

Congratulations on your new book

Congrats on your new book, Rosemary Wang. Your book looks interesting.

Congratulations!

Congratulations!

thanks Stephan, it looks clear to me now.

I think should be Skaffold instead of Scaffold? Scaffold is a class in Flutter actually.

Hi Ashish Choudhary,

I'm trying to understand the relationship between Kubernetes, Skaffold, and Spring-Boot.

From my understanding, Skaffold is a great tool for microservices development. It helps us build, push, and deploy steps for Kubernetes applications.
In the book description, you also mentioned that we will learn how to deploy Spring Boot apps to cloud platforms using Skaffold.

My question is, what is the relationship between Kubernetes and Spring-Boot?  Seems like both of them can be used to build applications?

Thanks.

you can take a look in What you will learn

So who will be the next lucky winner? :P
