onActivityResult not getting called after changing the intent for (Save the full-size photo)

Im following the official documentation to capture the image and gets its path.
https://developer.android.com/training/camera/photobasics
I have write 100% same code as the documentation say, but two weird things are happing when I write the simple intent
private fun dispatchTakePictureIntent() {
val takePictureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
try {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE)
} catch (e: ActivityNotFoundException) {
// display error state to the user
}
}
The OnAcivityResult is getting called
But when I change the intent into
private fun dispatchTakePictureIntent() {
Intent(MediaStore.ACTION_IMAGE_CAPTURE).also { takePictureIntent ->
// Ensure that there's a camera activity to handle the intent
takePictureIntent.resolveActivity(packageManager)?.also {
// Create the File where the photo should go
val photoFile: File? = try {
createImageFile()
} catch (ex: IOException) {
// Error occurred while creating the File
...
null
}
// Continue only if the File was successfully created
photoFile?.also {
val photoURI: Uri = FileProvider.getUriForFile(
this,
"com.example.android.fileprovider",
it
)
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI)
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE)
}
}
}
}
It does get called anymore.
Here is my OnAcivityResult code
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if(requestCode == OPEN_CAMERA)
if(resultCode == RESULT_OK && data != null) {
// not getting called
}
if(requestCode == OPEN_GALLERY)
if(resultCode == RESULT_OK && data != null) {
val image: Uri = data.data!!
openCropImageView(image)
}
if (resultCode == RESULT_OK && requestCode == UCrop.REQUEST_CROP) {
val uri = UCrop.getOutput(data!!)
val imgFile = File(uri?.path)
if (imgFile.exists()) {
val myBitmap = BitmapFactory.decodeFile(imgFile.absolutePath)
binding.previewImage.setImageBitmap(myBitmap)
}
}
}
any help, please.
Edit: Apparently its working fine on a pixel 5 running on android 11
emulator and its not working on Redmi note 5 running on android 8

How to load audio file in ListView?

I need to load random audio files from storage, into my ListView, on a button click. But I don't understand how can I do this. When I call intent, file manager open to pick file. My song must have title, artist name and url. But after clicking it doesn't add. This is my code. Don't scold me for a possibly dull question. I'm new at android developing.
private fun loadSong() {
val intent: Intent = Intent(Intent.ACTION_OPEN_DOCUMENT).apply {
type = "audio/*"
action = Intent.ACTION_GET_CONTENT
}
startActivityForResult(Intent.createChooser(intent, "Select Audio"), PICK_AUDIO)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == PICK_AUDIO && resultCode == RESULT_OK){
if (data != null) {
audioUri = data.data
}
}
adapter = SongsAdapter(listSongs)
twoTracksListView.adapter = adapter
}

How can I pass a variable control name to findViewById in Kotlin?

I am trying to learn Kotlin and I'm building a simple example as I go. I have 3 image buttons that open the camera and take a photo. The thumbnail is then set into an ImageView. I've used the examples from https://developer.android.com/training/camera/photobasics?hl=en to get the basics working (figuring if I can make it work for one, it'll work for all. It does indeed work for one, but I can't figure out how to make it one function that drops the thumbnail into the correct ImageView.
Inside my onCreate I have the listener for each of the buttons that will invoke the camera:
camRead1.setOnClickListener {dispatchTakePictureIntent() }
camRead2.setOnClickListener {dispatchTakePictureIntent() }
camRead3.setOnClickListener {dispatchTakePictureIntent() }
And I took the sample from the url above:
val REQUEST_IMAGE_CAPTURE = 1
private fun dispatchTakePictureIntent() {
val takePictureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
try {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE)
} catch (e: ActivityNotFoundException) {
// display error state to the user
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
val thumb: ImageView = findViewById(R.id.thumbRead1)
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
val imageBitmap = data.extras.get("data") as Bitmap
thumb.setImageBitmap(imageBitmap)
}
}
and pasted it into my class MainActivity, and after I replaced imageView in the override function with a variable (thumb) and added the super, it worked perfectly for the first one.
However, I am trying to get 3 photos, read1, read2, and read3 which each need to display the thumb in thumbRead1, thumbRead2 and thumbRead3. I can't figure out how the onActivityResult is executed since the call inside dispatchTakePictureIntent is calling startActivityForResult (especially as Android Studio says that startActivityForResult is deprecated).
Obviously, once onActivityResult executes, I can see that thumb defines R.id.thumbRead1 and receives imageBitmap but I don't understand how I can make it aware of the button that was clicked.
Without understanding how onActivityResult is called, I'm thinking that if I can do something like:
findViewById(R.id("thumbRead" + imgID))
to define the specific ImageView that I want the photo pasted into. Am I on the right track here? If not, what is the recommended way of doing this?

Note they've recently added what's supposed to be a cleaner way of starting other activities for results and getting the results, explained here. But since you're already doing it the traditional way, I'll explain how to get that working.
I think the easiest thing to do in this situation is just make more request codes, so you can check which request it was.
val REQUEST_IMAGE_CAPTURE_SOURCE_1 = 1
val REQUEST_IMAGE_CAPTURE_SOURCE_2 = 2
val REQUEST_IMAGE_CAPTURE_SOURCE_3 = 3
//...
camRead1.setOnClickListener { dispatchTakePictureIntent(REQUEST_IMAGE_CAPTURE_SOURCE_1) }
camRead2.setOnClickListener { dispatchTakePictureIntent(REQUEST_IMAGE_CAPTURE_SOURCE_2) }
camRead3.setOnClickListener { dispatchTakePictureIntent(REQUEST_IMAGE_CAPTURE_SOURCE_3) }
//...
private fun dispatchTakePictureIntent(requestCode: Int) {
val takePictureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
try {
startActivityForResult(takePictureIntent, requestCode)
} catch (e: ActivityNotFoundException) {
// display error state to the user
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode != RESULT_OK) {
// possibly show message to user
return
}
val imageViewId = when (requestCode) {
REQUEST_IMAGE_CAPTURE_SOURCE_1 -> R.id.thumbRead1
REQUEST_IMAGE_CAPTURE_SOURCE_2 -> R.id.thumbRead2
REQUEST_IMAGE_CAPTURE_SOURCE_3 -> R.id.thumbRead3
}
val imageView = findViewById<ImageView>(imageViewId)
imageView.imageBitmap = data.extras.get("data") as Bitmap
}
By the way, if you want to get an ID for a view using the String like you were showing you were trying, you would do it like this:
val viewId = resources.getIdentifier("thumbRead$imgId", "id", packageName)
val imageView = findViewById<ImageView>(viewId)

You need to pass different request code for each call and pass it to the dispatchTakePictureIntent function. You do not need to get id by findviewbyid. You simply can add the image on the basis of the request code.
val REQUEST_IMAGE_CAPTURE_ONE = 1
val REQUEST_IMAGE_CAPTURE_TWO = 2
val REQUEST_IMAGE_CAPTURE_THREE = 3
private fun dispatchTakePictureIntent(requestCode: Int) {
val takePictureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
try {
startActivityForResult(takePictureIntent, requestCode)
} catch (e: ActivityNotFoundException) {
// display error state to the user
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == RESULT_OK) {
val imageBitmap = data.extras.get("data") as Bitmap
if (requestCode == REQUEST_IMAGE_CAPTURE_ONE ) {
thumbRead1.setImageBitmap(imageBitmap)
}else if (requestCode == REQUEST_IMAGE_CAPTURE_TWO ) {
thumbRead2.setImageBitmap(imageBitmap)
}else if (requestCode == REQUEST_IMAGE_CAPTURE_THREE ) {
thumbRead3.setImageBitmap(imageBitmap)
}
}
}

Android Image setImageBitmap not working when using glide load image

I have a problem using Glide load image android.I will present it simply as follows:
First I load image using glide
I want to choose image using Intent.ACTION_PICK but when I using image.setImageBitmap on onActivityResult but it not working
Glide.with(context!!).load(url).centerCrop().error(R.drawable.avata_boy).into(imgAvata)
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == PICK_IMAGE_REQUEST && resultCode == Activity.RESULT_OK
&& data != null && data.data != null
) {
filePath = data.data
try {
val bitmap = BitmapFactory.decodeStream(activity!!.contentResolver.openInputStream(filePath!!))
imgAvata.setImageBitmap(bitmap)
Glide.with(context!!)
.load(bitmap)
.placeholder(R.drawable.avata_boy)
.diskCacheStrategy(DiskCacheStrategy.NONE)
.skipMemoryCache(true)
.into(imgAvata)
} catch (e: IOException) {
}

Try this!!
val myBitmap = BitmapFactory.decodeFile(filePath!!.getAbsolutePath())
imgview.setImageBitmap(myBitmap)

android camera: onActivityResult() intent is null if it had extras

After searching a lot in all the related issues at Stack Overflow and finding nothing, please try to help me.
I created an intent for capture a picture. Then I saw different behavior at onActivityResult(): if I don't put any extra in the Intent (for small pics) the Intent in onActivityResult is ok, but when I put extras in the intent for writing the pic to a file, the intent in onActivityResult is null!
The Intent creation:
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// without the following line the intent is ok
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(takePictureIntent, actionCode);
Why is it null, and how can I solve it?

It happens the same to me, if you are providing MediaStore.EXTRA_OUTPUT, then the intent is null, but you will have the photo in the file you provided (Uri.fromFile(f)).
If you don't specify MediaStore.EXTRA_OUTPUT then you will have an intent which contains the uri from the file where the camera has saved the photo.
Don't know if it as a bug, but it works that way.
EDIT: So in onActivityResult() you no longer need to check for data if null. The following worked with me:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case PICK_IMAGE_REQUEST://actionCode
if (resultCode == RESULT_OK && data != null && data.getData() != null) {
//For Image Gallery
}
return;
case CAPTURE_IMAGE_REQUEST://actionCode
if (resultCode == RESULT_OK) {
//For CAMERA
//You can use image PATH that you already created its file by the intent that launched the CAMERA (MediaStore.EXTRA_OUTPUT)
return;
}
}
}
Hope it helps

A sample written in Kotlin. You create a Uri for camera app, CameraFragment holds it until camera returns from saving your picture and gives it back to you in onActivityResult as you would expect.
CameraFragment.kt
Acts as an intermediary between consumer and camera app. Takes Uri as input and returns it in data Intent.
class CameraFragment : Fragment() {
companion object {
val TAG = CameraFragment::class.java.simpleName
private val KEY_URI = ".URI"
fun newInstance(uri: Uri, targetFragment: Fragment, requestCode: Int): CameraFragment {
val args = Bundle()
args.putParcelable(KEY_URI, uri)
val fragment = CameraFragment()
fragment.arguments = args
fragment.setTargetFragment(targetFragment, requestCode)
return fragment
}
}
private lateinit var uri: Uri
private var fired = false
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
retainInstance = true
fired = savedInstanceState?.getBoolean("fired") ?: false
if (!fired) {
val args = arguments
uri = args.getParcelable(KEY_URI)
val i = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
i.putExtra(MediaStore.EXTRA_OUTPUT, uri)
i.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
context.grantUriPermission(i, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
startActivityForResult(i, targetRequestCode)
fired = true
}
}
override fun onSaveInstanceState(outState: Bundle) {
super.onSaveInstanceState(outState)
outState.putBoolean("fired", fired)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == targetRequestCode) {
context.revokeUriPermission(uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
val newData = Intent()
newData.data = uri
targetFragment.onActivityResult(requestCode, resultCode, newData)
dismiss()
}
}
private fun dismiss() {
fragmentManager.beginTransaction().remove(this).commit()
}
}
/** Grant Uri permissions for all camera apps. */
fun Context.grantUriPermission(intent: Intent, uri: Uri, modeFlags: Int) {
val resolvedIntentActivities = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (resolvedIntentInfo in resolvedIntentActivities) {
val packageName = resolvedIntentInfo.activityInfo.packageName;
grantUriPermission(packageName, uri, modeFlags);
}
}
Invoke camera intent
this is a fragment in your app which will trigger the camera. RC_CAMERA is your request code for this action.
val uri = /* Your output Uri. */
val f = CameraFragment.newInstance(uri, this, RC_CAMERA)
fragmentManager.beginTransaction().add(f, CameraFragment.TAG).commit()
Handle camera result
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
when(requestCode) {
RC_CAMERA -> {
if (resultCode == Activity.RESULT_OK) {
val uri = data?.data
// Do whatever you need.
}
}
}
}

Where did you create the ffor the Uri.fromFile(f)?
It must be a valid File object. Try to create it before the EXTRA_OUTPUT line.
File f = new File("valid path");
Try with something like this:
File file = new File(dataFile);
Uri outFileUri = Uri.fromFile(file);
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
intent.putExtra(MediaStore.EXTRA_OUTPUT, outFileUri);
startActivityForResult(intent, TAKE_PHOTO);

use the following:
Bitmap bitmap = data.getExtras().getParcelable("data");
it works.
