Hi Guys, Can somebody who experienced similar problem like mine is, to help me to resolve it. The problem is following: Going throw leadbolt tutorial when put code at the picture a get following errors: for the protected void onCreate... "The method on create Bundle of type SB Live wallpapers must override or implement a super type method" and for the setContentView "the method set contenView is undefined for the type SBlivewallpaper" I made layout.xml to try to fix it with that, but the error still exists. Note: xxxxxxx is the name of xml file in layout folder.
