在我的应用程序中，我无法将我从相机拍摄的照片传输到应用程序

Question

I made an automobile management application.

I made a vehicle image adding system in the application.

When the Image is selected I want to upload it to firebase and view it.

When I select a picture from the gallery, I can upload and view it, it works without any problems.

At the same time, when I select Camera, I ask for permission and access the camera, but this is the part that doesn't work. After I take the picture from the camera, I return to the application, but the picture I took is not visible. I don't know how to do this.

And.. I don't know how to code.

I'm trying to watch video lessons and adapt them the way I want to make the applications in my head.

This application is the last point I came to.

As far as I saw the answers to the previous questions and the videos, I could not answer this question.

I know it will be difficult, but can you show this ignorant the correct method?

    Uri imageData;

    private StorageReference storageReference;

    @Override

        super.onCreate(savedInstanceState);

        //Burada Yazan kod ustteki standart titleyi kaldirmak icin.
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
        getSupportActionBar().hide();
        // Burada Bitiyor.

        binding = ActivityUploadBinding.inflate(getLayoutInflater());
        View view = binding.getRoot();
        setContentView(view);

        registerLauncher();


        //Firebase fireStorage icin

        storageReference = firebaseStorage.getReference();

Answer 1

A couple of things. You should use request codes, so you can check for it in you activity result method and use some logic to distinguish between taking a picture and selecting a photo from the gallery. Because the Gallery and Camera return different different things. Second, the image taken from the camera isn't saved. It doesn't have a URI location, because it's just in memory.

if(intentFromResult != null) {
       imageData = intentFromResult.getData();
       Bitmap img = (Bitmap)(data.getExtras().get()'data'));
       //Upload img to Database
       //Set imageView from Database
}

Here is the documentation on the way you are trying to implement it:
https://developer.android.com/training/camera-deprecated/photobasics

Here is the current documentation on how it should be implemented: https://developer.android.com/guide/topics/media/camera

And one last bit to think about. It might be better to use a library so you don't have to write a whole new implementation. I've used https://github.com/Dhaval2404/ImagePicker before, it's ok. There might be a better one out there that suits your needs. Take your time and look around.
