Android Camera Intent not working in OnePlus devices

I was trying to use the native camera app that comes pre-installed in Android devices to capture the images for my app. For this I've been using this code:

A function is called when the user taps on button

take_img_btn.setOnClickListener {
    dispatchTakePictureIntent()
}

That function is supposed to do this:

    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
                    ex.printStackTrace()
                    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)
                }
            }
        }
    }


    private fun createImageFile(): File {
        // Create an image file name
        val timeStamp: String = SimpleDateFormat("yy-MM-dd-HH-mm-ss-SS",Locale.getDefault()).format(System.currentTimeMillis())
        val storageDir: File? = getExternalFilesDir(Environment.DIRECTORY_PICTURES)
        return File.createTempFile(
            "FNL_${timeStamp}_",
            ".jpg",
            storageDir /* directory */
        ).apply {
            // Save a file: path for use with ACTION_VIEW intents
            currentPhotoPath = absolutePath
            currentPhotoName = name
        }
    }

And the FileProvider is configured in the Manifest like so

<application>
   ...
   <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="com.example.android.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"></meta-data>
    </provider>
    ...
</application>

I am also asking for Camera feature in Manifest

<manifest>
    ...
    <uses-feature
        android:name="android.hardware.camera"
        android:required="true" />
    ...
</manifest>

When I run this app on my android device (Realme 6 Pro) and tap the button then:

  1. The app opens the native camera app
  2. I can capture the image
  3. The image is saved to the location where it was specified

But when this same app is deployed on OnePlus devices (in our case OnePlus Nord) and tap the button then nothing happens. It feels like the button is not programmed.

This code is taken from here: https://developer.android.com/training/camera/photobasics

It would be really helpful if someone help.

As @CommonsWare suggested, here is what I did.

I basically avoided the usage of resolveActivity() and did it in my own style instead of just copy-paste from Official Google Documentation

Here is my final call for camera app:

    private fun dispatchTakePictureIntent() {
        val cameraIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
        val photoFile: File? = try {
            createImageFile()
        } catch (ex: IOException) {
            // Error occurred while creating the File
            ex.printStackTrace()
            null
        }

        if (photoFile != null){
            val photoURI: Uri = FileProvider.getUriForFile(
                this,
                "com.example.android.fileprovider",
                photoFile
            )
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI)
            startActivityForResult(cameraIntent, REQUEST_IMAGE_CAPTURE)
        }
    }


    private fun createImageFile(): File {
        // Create an image file name
        val timeStamp: String = SimpleDateFormat("yy-MM-dd-HH-mm-ss-SS",Locale.getDefault()).format(System.currentTimeMillis())
        val storageDir: File? = getExternalFilesDir(Environment.DIRECTORY_PICTURES)
        return File.createTempFile(
            "FNL_${timeStamp}_",
            ".jpg",
            storageDir /* directory */
        ).apply {
            // Save a file: path for use with ACTION_VIEW intents
            currentPhotoPath = absolutePath
            currentPhotoName = name
        }
    }

At last, thank you very much @CommonsWare

in higher version devices like Oneplus nord with android 11 or 12 the camera intent not working i added this code it is worked for me

Add this line in AndroidManifest.xml

<queries>
        <intent>
            <action android:name="android.media.action.IMAGE_CAPTURE" />
        </intent>
    </queries>

and also add your other permission required for camera

user_177108370

check AndroidManifest.xml for following change

<manifest ... >
    <uses-feature android:name="android.hardware.camera"
                  android:required="true" />
    ...
</manifest>

Make sure you ask camera permission before camera open.

try to ask run time permissions.
