good evening. taking course in android , having issues compiling app.
i following this tutorial. have earlier set requestqueue requests.
this mainactivity.java file:

try { name = inbundle.getstring("name"); surname = inbundle.getstring("surname"); imageurl = inbundle.getstring("imageurl"); textview nameview = (textview) findviewbyid(r.id.nameandsurname); nameview.settext("" + name + " " + surname); } catch (exception e){ log.e("error on setcontent", e.getmessage()); }
in mainactivity, have this:
bundle inbundle = getintent().getextras(); name = inbundle.getstring("name"); surname = inbundle.getstring("surname"); imageurl = inbundle.getstring("imageurl"); but first time load it, inbundle null. should check if null before running getstring on it:
bundle inbundle = getintent().getextras(); if(inbundle!=null){ name = inbundle.getstring("name"); surname = inbundle.getstring("surname"); imageurl = inbundle.getstring("imageurl"); }
