Hey guys. I want to open the gallery of the device and display the image selected bythe user back. I make a button and and an ActionListener should deflect me to the device's gallery. But the simulator shows a blank screen even if I omit the opening of the gallery part and just add the button. Also, It gives the following exception in the log:- > Jul 20, 2017 4:11:00 PM java.util.prefs.WindowsPreferences <init> > WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at > root 0x80000002.
