"requestCode" is used in order for the app to differentiate the request that is given. We need to create an if statement in the “onActivityResult” function in order to pass the data to the main activity.

[@fwajed]

You can update this segment or add a new segment that uses ActivityResultContracts

[@Harkie_21]

2023 UPDATE: This is what the code should look like using non-depreciated methods: val getContent = registerForActivityResult(GetContent()) { uri: Uri? -> // Handle the returned Uri binding.ivPhoto.setImageURI(uri) } binding.btnTakePhoto.setOnClickListener { getContent.launch("image/*") } I am still learning, so there may be a better way to implement this. This is from my research and what worked for me! * make sure to import "androidx.activity.result.contract.ActivityResultContracts.GetContent" and "android.net.Uri" *

[@rowenarrow]

Solid video even if though the API has changed a bit and it alters what we will do this video still covers concepts and thought process and it is becoming fun trying to figure out how to adjust the code to replicate the results.

I love your tutorials! There are some error caused by deprecated codes. Pls recreate this tutorial with latest code.

[@mattgraves3709]

Nicely done, thank you very much. I have always loved the implicit intent system, but I was a little cloudy on how to work with it but not anymore. I feel like I also understand a larger concept here as well so many thanks!

For Android 11, startActivityForResult is deprecated, looking at samples for ActivityResultRegistry but can't seem to get it working for this tutorial. Any help would be appreciated.

[@51bpegasi]

This seems to work: package com.tutorials.implicitintent import android.content.Intent import androidx.appcompat.app.AppCompatActivity import android.os.Bundle import androidx.activity.result.contract.ActivityResultContracts import com.tutorials.implicitintent.databinding.ActivityMainBinding class MainActivity : AppCompatActivity() { lateinit var bindingMain: ActivityMainBinding var getContent = registerForActivityResult( ActivityResultContracts.GetContent()) { bindingMain.ivPhoto.setImageURI(it) } override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) bindingMain = ActivityMainBinding.inflate(layoutInflater) setContentView(bindingMain.root) bindingMain.btTakePhoto.setOnClickListener { Intent(Intent.ACTION_GET_CONTENT).also { it -> it.type = "image/*" getContent.launch(it.type) } } } }

registerForActivityResult gets it done. This is the whole code: val btnChoseImage: Button = findViewById(R.id.btnChooseImage) val ivImage: ImageView = findViewById(R.id.ivImage) val getImage = registerForActivityResult(ActivityResultContracts.GetContent()) { uri: Uri-> ivImage.setImageURI(uri) } btnChoseImage.setOnClickListener { getImage.launch("image/*") }

how can i go outside of any callback function in general in kotlin for example if the callback that i am in is returning null to one of the parameters Because in this context.. i am trying to implement onActivityResult() callback function which is part of an abstract class ActivityResultLauncher (Because this is the new way i guess) so the function now ask me what i want to do with the uri:Uri? object (i hope you know what i mean here) i want to check if it is null i want it to go out of the callback function i tried to say " if(uri==null) return " but did not work and i try "if(uri==null) return@onActivityResult" because this is recommended by the IDE.. is this the correct way to do?

[@footballCartoon91]

First we call " registerForActivityResult()" which then returns an abstract class called "ActivityResultLauncher" which we needs to implement or override inside there are 3 abstract methods that we need to implement/override 1. getContract() //return ActivityResultContract 2. launch(input: I!, options: ActivityOptionsCompat?) // return Unit 3. unregister() //return @MainThread Unit

[@darwingsanchez5328]

It was so good tutorial, I have a question, in case I need to do the same thing but instead uploading the image to Image View I would to set the activity background ?

Great content bro Have a question When you click the image in the image Activity how does the intent know it should finish/destroy the image Activity and pass the image clicked to the Main activity ?

[@PhilippLackner]

The gallery app is programmed that way. You can declare intent-filters and declare your app as an app that can open images for example

you can use ActivityResultContracts, to know how to use check out the google guide which provides a similar example used in this video: developer.android.com/training/basics/intents/result#launch

startActivityForResult has been deprecated

[@meirox03]

As the code for the intent is now deprecated I was able to do it like this: var ivImage = findViewById(R.id.ivImage) val getContent = registerForActivityResult(ActivityResultContracts.GetContent()) { uri: Uri? -> ivImage.setImageURI(uri) } val btnGalery = findViewById(R.id.btnGalery) btnGalery.setOnClickListener { getContent.launch("image/*") }

[@Harkie_21]

You can use binding to access element by ID. For example : binding.ivImage.setImageURI(uri)

[@naginipython2772]

Alright yall, I came up with a solution (as of 2023): val image = findViewById(R.id.[your imageview name]) val content = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result -> if (result.resultCode == Activity.RESULT_OK) { val data = result.data?.data image.setImageURI(data) } } findViewById(R.id.[your button name]).setOnClickListener { val myIntent = Intent(Intent.ACTION_GET_CONTENT).also { it.type = "image/*" content.launch(it) } }

[@DanielTobi00]

thanks man.

[@alymohamed5966]

startActivityForResult() is deprecated instead you should create an ActivityResultLauncher object using the function registerForActivityResult() with a lambda function that handles the results come from launched activity. Creating a resultLauncher : private val resultLauncher = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) {result-> if(result.resultCode == Activity.RESULT_OK){ val data = result.data?.data binding.[YOUR IMAGE VIEW].setImageURI(data) } }

[@rowenarrow]

I personally just used startActivityIfNeeded(it, 0), but I am saving this to come back to to do the proper way. My way did work though.
