How can I automate taking and returning a pic

Question

I've the below code working fine, that upon button click, the Camera intent is opened, allowing me to take a photo, then confirm the photo is ok, i.e. 2 interfaces from the user after clicking the button, till the pic is loaded in the image view. Can I automate it, i.e. once the user click the button on the activity, camera intent is opened directly, take a photo of whatever there, and return what had been captured to the user.

mm, i.e. something like the apps working with take a selfie voice command.

My typical code for opening the camera intent is:

btnCamera.setOnClickListener {   // I need this click to be the only thing done by the user 
    if(isPermissionGranted(permission.CAMERA)) startCamera()
     else requestCameraPermission(this)
}

private fun startCamera() {
    val fileName = System.currentTimeMillis().toString() + ".jpeg"
    output = File(
       this.getExternalFilesDir(Environment.DIRECTORY_PICTURES),
       fileName
    )

    val intent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
    outPutFileUri = this.let { it ->
        FileProvider.getUriForFile(
           it,
           BuildConfig.APPLICATION_ID,
           output!!
        )
     }
     intent.putExtra(MediaStore.EXTRA_OUTPUT, outPutFileUri)
     startActivityForResult(intent, REQUEST_IMAGE_CAPTURE)
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) = runBlocking {
    super.onActivityResult(requestCode, resultCode, data)
    val activity = this
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK) {
        val bitmap = outPutFileUri?.let { getCapturedImage(it) }
        imageView.setImageBitmap(bitmap)
    }
}

private fun getCapturedImage(selectedPhotoUri: Uri): Bitmap =
    when {
         Build.VERSION.SDK_INT < 28 -> MediaStore.Images.Media.getBitmap(
           contentResolver, selectedPhotoUri)
    else -> {
          val source = ImageDecoder.createSource(contentResolver, selectedPhotoUri)
          ImageDecoder.decodeBitmap(source)
    }
}

The Camera will be opened, picture will be taken, user will see what is going on the screen,, mm if there is a way to take a pic without opening the camera app it will be welcomed as well. thanks

Do you mean without opening camera you want to capture photo ? — M D, Sep 24 '19 at 11:12

No.

You would need to implement your own camera app functionality for automated image capture, whether using the camera APIs directly or via a wrapper library (CameraX, Fotoapparat, CameraKit-Android, etc.).
