I'm currently learning how to use android studio in java and am trying to make a social media app. I am currently creating an edit profile page where the user would update their details and upload a profile picture.

I have been following tutorials online and all of the ones I have come across use the startActivityForResult method. It has been crossed out and wont call the method as it is deprecated. But I don't know what to use instead.

`ProfileImage.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { //open gallery

            Intent OpenGalleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(OpenGalleryIntent, 1000);
        }
    });
}
@Override
protected void onActivityResult(int requestCode, int resultCode, @androidx.annotation.Nullable Intent data){
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == 1000){
        if(resultCode == Activity.RESULT_OK){
            Uri imageUri = data.getData();
            ProfileImage.setImageURI(imageUri);
            UploadImageToFirebase(imageUri);
        }
    }
}
private void UploadImageToFirebase(Uri image){
    StorageReference fileRef = storageReference.child("Profile.jpg");
    fileRef.putFile(image).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            Toast.makeText(Edit_Profile.this, "Image Uploaded", Toast.LENGTH_SHORT).show();
        }
    });![enter image description here](https://i.stack.imgur.com/padRc.jpg)`

I know there is an alternative but I don't understand how it works.

CodePudding user response：

Yes startActivityForeResult is deprecated.

Now you can use ActivityResultLauncher for the callbacks

CodePudding user response：

startActivityForResult is indeed deprecated in later versions of AndroidX Activity and Fragment APIs (while I believe you can still use it despite of warning). New way to get result from activity is registerForActivityResult.

In your code you would need to create a launcher, which will handle result (selected image)

private final ActivityResultLauncher<Intent> launcher = registerForActivityResult(
            new ActivityResultContracts.StartActivityForResult(),
            result -> {
                if (result.getResultCode() == Activity.RESULT_OK 
                       && result.getData() != null) {
                    Uri photoUri = result.getData().getData();
                    //use photoUri here
                }
            }
    );

and then launch this launcher in onClickListener

profileImage.setOnClickListener(view -> {
            Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            launcher.launch(intent);
        });
