The android application crash

Question

WhoDoctor was helped me on the Previous code

Now, the android application crashed when during running on my phone and This is the error log

First problem is after I scanned the QRcode with camera it cannot show at the QRcode's result into the tvResult

Second problem is after I selected a QRcode image from the storage, then tap confirmed, it crash

Here below I think are the issue

Type mismatch: inferred type is Uri? but Uri was expected

galleryLauncher = registerForActivityResult(ActivityResultContracts.StartActivityForResult(), object :ActivityResultCallback<ActivityResult>{
            override fun onActivityResult(result: ActivityResult?) {
                val data=result?.data
                inputImage = InputImage.fromFilePath(requireContext(), data?.data)
                processQr()
            }
        })

Redundant SAM-constructor

binding.btnScanBarcode.setOnClickListener{
            val options=arrayOf("camera","gallery")

            val builder=AlertDialog.Builder(requireContext())
            builder.setTitle("Pick a option")

            builder.setItems(options, DialogInterface.OnClickListener { dialog, which ->
                if(which==0){
                    val cameraIntent=Intent(MediaStore.ACTION_IMAGE_CAPTURE)
                    cameraLauncher.launch(cameraIntent)
                }else{
                    val storageIntent=Intent()
                    storageIntent.setType("image/*")
                    storageIntent.setAction(Intent.ACTION_GET_CONTENT)
                    galleryLauncher.launch(storageIntent)
                }
            })
            builder.show()
        }

'onRequestPermissionsResult(Int, Array<(out) String!>, IntArray): Unit' is deprecated. Deprecated in Java

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)

        if(requestCode==CAMERA_PERMISSION_CODE){
            if(grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED){
                checkPermission(
                    Manifest.permission.READ_EXTERNAL_STORAGE,
                    READ_STORAGE_PERMISSION_CODE)
            }else{
                Toast.makeText(requireContext(), "Camera Permission Denied", Toast.LENGTH_SHORT).show()
            }
        }else if(requestCode==READ_STORAGE_PERMISSION_CODE){
            if((grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED)){
                checkPermission(
                    Manifest.permission.WRITE_EXTERNAL_STORAGE,
                    WRITE_STORAGE_PERMISSION_CODE)
            }else{
                Toast.makeText(requireContext(), "Storage Permission Denied", Toast.LENGTH_SHORT).show()
            }
        }else if(requestCode==WRITE_STORAGE_PERMISSION_CODE) {
            if (!(grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
                Toast.makeText(requireContext(), "Storage Permission Denied", Toast.LENGTH_SHORT).show()
            }
        }
    }

onRequestPermissionsResult() method is deprecated in androidx.fragment.app.Fragment.

So you use registerForActivityResult() method instead onRequestPermissionsResult().

Following is kotlin code. .

val permReqLuncher = registerForActivityResult(ActivityResultContracts.RequestPermission()){
  if (it) {
     // Good pass
  } else {
     // Failed pass
  }
}

How to get a permission request in new ActivityResult API (1.3.0-alpha05)?

private ActivityResultLauncher<String> mPermissionResult = registerForActivityResult(
        new ActivityResultContracts.RequestPermission(),
        new ActivityResultCallback<Boolean>() {
            @Override
            public void onActivityResult(Boolean result) {
                if(result) {
                    Log.e(TAG, "onActivityResult: PERMISSION GRANTED");
                } else {
                    Log.e(TAG, "onActivityResult: PERMISSION DENIED");
                }
            }
        });



        // Launch the permission window -- this is in onCreateView()
    floatingActionButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
         mPermissionResult.launch(Manifest.permission.ACCESS_BACKGROUND_LOCATION);

        }
    });

You can request multiple permissions.

val requestMultiplePermissions = registerForActivityResult(ActivityResultContracts.RequestMultiplePermissions()) { permissions ->
    permissions.entries.forEach {
        Log.e("DEBUG", "${it.key} = ${it.value}")
    }
}

requestMultiplePermissions.launch(
    arrayOf(
        Manifest.permission.READ_CONTACTS,
        Manifest.permission.ACCESS_FINE_LOCATION
   )
)
