当相机应用程序打开以在android studio中获取图像时，您可以打开图库吗？

Question

I'm working on an native android application in Java. I have already implemented camera functionalities that upload images to firebase storage when captured, but I expected that you could also open your gallery from the camera and upload those images like facebook messenger. Until now I have only found tutorials that separate camera and gallery with a menu that appears by clicking an add button .

Where gallery should normally be located in the camera application

Answer 1

Facebook messenger is implementing their own gallery, reading files probably from MediaStore.

If you want to open the gallery from your app and pick a picture you should launch an intent:

private val pickImageFromGallery = registerForActivityResult(ActivityResultContracts.GetContent()) { 
  uri: Uri? ->
    uri?.let { 
      // handle the data here
    }
}

Then launch the intent from a button click or something else:

pickImageFromGallery.launch("image/*")
