How to make a gallery?

Question

Hello :) I took months with the problem, I already read the documentation.

https://creativesdk.adobe.com/docs/android/#/articles/gettingstarted/index.html

My application

The image is connected to a url :/

I want to know how to do to put a gallery and the user can select the image so you can edit, and the same with the camera.

Launching the Gallery

If you want to choose an image from the device's Gallery, you can do something like this:

Intent galleryPickerIntent = new Intent();
galleryPickerIntent.setType("image/*");
galleryPickerIntent.setAction(Intent.ACTION_GET_CONTENT);

startActivityForResult(Intent.createChooser(galleryPickerIntent, "Select an Image"), 203); // Can be any int

This starts a new activity that we expect to give us some kind of result (in this case, it will be an image Uri).

A common use case is to launch the Gallery when the user clicks a button:

View.OnClickListener openGalleryButtonListener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent galleryPickerIntent = new Intent();
        galleryPickerIntent.setType("image/*");
        galleryPickerIntent.setAction(Intent.ACTION_GET_CONTENT);

        startActivityForResult(Intent.createChooser(galleryPickerIntent, "Select an Image"), 203); // Can be any int
    }
};
mOpenGalleryButton.setOnClickListener(openGalleryButtonListener);

This code will either open the Gallery directly, or first show the user a chooser that lets them select which app to use as a source of images.

Receiving results

To receive the image that the user selects, we will use the onActivityResult() method:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    mAuthSessionHelper.onActivityResult(requestCode, resultCode, data);

    if (resultCode == RESULT_OK && requestCode == 203) { // the int we used for startActivityForResult()

        // You can do anything here. This is just an example.
        mSelectedImageUri = data.getData();
        mSelectedImageView.setImageURI(mSelectedImageUri);

    }
}

I put some example code in the if block, but what you do there will depend on your app.
