I managed to fix the issue on my side, and now the forms a properly
finalizing, but the memory leak is still there. This is the new code:
public void start() {
if(current != null){
current.show();
return;
}
mainForm();
}
private void mainForm() {
Form hi = new Form("Map Test", new
BorderLayout(BorderLayout.CENTER_BEHAVIOR_CENTER_ABSOLUTE)) {
protected void finalize() throws Throwable {
Log.p("Finaliza Form 1");
}
};
Button btn = new Button("Show Map");
hi.add(BorderLayout.CENTER, btn);
hi.show();
btn.addActionListener((evt) -> {
showMap();
});
}
private void showMap() {
Form hi2 = new Form("Map show", new BorderLayout()) {
protected void finalize() throws Throwable {
Log.p("Finaliza Form 2");
}
};
hi2.setTransitionOutAnimator(CommonTransitions.createSlide(CommonTransitions.SLIDE_HORIZONTAL,
true, 250));
MapContainer map = new MapContainer(MAP_KEY);
hi2.add(BorderLayout.CENTER, map);
hi2.show();
Command back = new Command("Back") {
@Override
public void actionPerformed(ActionEvent evt) {
hi2.removeComponent(map);
mainForm();
}
};
hi2.getToolbar().addCommandToLeftBar(back);
hi2.setBackCommand(back);
}
And this is the stack trace when the app crashes with OOM Error:
