iOS save to storage issue - codenameone

Question

I've an issue while trying to save an image to the Storage in iOS. Image is downloaded but not saved.
The code is:
Form hi = new Form("Toolbar", new BoxLayout(BoxLayout.Y_AXIS));
TreeModel tm = new TreeModel() {
#Override
public Vector getChildren(Object parent) {
String[] files;
if (parent == null) {
files = FileSystemStorage.getInstance().getRoots();
return new Vector<Object>(Arrays.asList(files));
} else {
try {
files = FileSystemStorage.getInstance().listFiles((String) parent);
} catch (IOException err) {
Log.e(err);
files = new String[0];
}
}
String p = (String) parent;
Vector result = new Vector();
for (String s : files) {
result.add(p + s);
}
return result;
}
#Override
public boolean isLeaf(Object node) {
return !FileSystemStorage.getInstance().isDirectory((String) node);
}
};
Command tree = new Command("Show tree") {
#Override
public void actionPerformed(ActionEvent evt) {
Form treeForm = new Form("Tree", new BorderLayout());
Tree t = new Tree(tm) {
#Override
protected String childToDisplayLabel(Object child) {
String n = (String) child;
int pos = n.lastIndexOf("/");
if (pos < 0) {
return n;
}
return n.substring(pos);
}
};
treeForm.add(BorderLayout.CENTER, t);
Command back = new Command("Back") {
#Override
public void actionPerformed(ActionEvent evt) {
hi.showBack();
}
};
Button backButton = new Button(back);
treeForm.add(BorderLayout.SOUTH, backButton);
treeForm.show();
}
};
hi.getToolbar().addCommandToOverflowMenu(tree);
EncodedImage placeholder = EncodedImage.createFromImage(Image.createImage(hi.getWidth(), hi.getWidth() / 5, 0xffff0000), true);
String photoURL = "https://awoiaf.westeros.org/images/thumb/9/93/AGameOfThrones.jpg/400px-AGameOfThrones.jpg";
StringBuilder fsPath = new StringBuilder(FileSystemStorage.getInstance().getAppHomePath());
fsPath.append("400px-AGameOfThrones.jpg");
URLImage background = URLImage.createToStorage(placeholder, fsPath.toString(), photoURL);
background.fetch();
Style stitle = hi.getToolbar().getTitleComponent().getUnselectedStyle();
stitle.setBgImage(background);
stitle.setBackgroundType(Style.BACKGROUND_IMAGE_SCALED_FILL);
stitle.setPaddingUnit(Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS);
stitle.setPaddingTop(15);
SpanButton credit = new SpanButton("Link");
credit.addActionListener((e) -> Display.getInstance().execute("https://awoiaf.westeros.org/index.php/A_Game_of_Thrones"));
hi.add(new SpanLabel("A")).
add(new Label("B", "Heading")).
add(credit);
ComponentAnimation title = hi.getToolbar().getTitleComponent().createStyleAnimation("Title", 200);
hi.getAnimationManager().onTitleScrollAnimation(title);
hi.show();

The tree is only to see if the image was saved in the Storage.

Answer 1

You are mixing Storage & FileSystemStorage which are very different things see this.
You can use storage which is a flat set of "files" and that's what URLImage.createToStorage does. But then you need to use the Storage API to work with that and it might not be visible in the FileSystemStorage API.
Alternatively you might be looking for URLImage.createToFileSystem().
