Using GalleryPicker

GalleryPicker opens the gallery picker and returns the selected image name plus the image file itself. Use it when you need to let the user choose an existing image from the device.

Basic flow

1. Open the picker with GalleryPicker.open(...).
2. Read the imageName and imageFile values in onSuccess.
3. Use the returned File as needed in your logic.

Example

GalleryPicker.open(new GalleryPicker.Listener() {
    public void onSuccess(String imageName, File imageFile) {
        Terminal.log(imageName);
        Terminal.log(imageFile.getAbsolutePath());
    }

    public void onCancel() {
        Terminal.log("Gallery picker cancelled");
    }

    public void onError(String error) {
        Terminal.log(error);
    }
});

Notes

• onSuccess receives the image name and the selected file.
• onCancel runs when the user closes the picker without choosing an image.
• onError runs when the picker cannot complete the operation.
