and code line 423 looks this:

public boolean wczytajmape() { if (mmap == null) { supportmapfragment mapfrag = (supportmapfragment) getsupportfragmentmanager() .findfragmentbyid(r.id.map); mmap = mapfrag.getmap(); mmap.setonmarkerclicklistener(this); \\----->423 line mmap.setmylocationenabled(true); } homecoming (mmap != null); }

this error annoying , happens on api 10 , api 17, checked. didn't test on version. can help me?

check emulator (avd manager) has google play api version, if not not able utilize maps , more features

hope helps

edit: afraid wrong, not able utilize maps in emulator directly. google not providing means it.

there no official ways have these features, highly discouraged, not recommend using them.
