i sorry forgetting paste main activity.

the line 27

public class mainactivity extends appcompatactivity  {  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main); 

super.oncreate(savedinstancestate); line 27.

sorry answer old question,but solved exception in project.

i think leads exception using context of our activity when creating.

my code like：

@override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);         regtowx(); }   private void regtowx(){     iwxapi  api;     api = wxapifactory.createwxapi(this, constants.wx_app_id, true);     api.registerapp(constants.wx_app_id);     string text = "123";     wxtextobject textobj = new wxtextobject();     textobj.text = text;      wxmediamessage msg = new wxmediamessage();     msg.mediaobject = textobj;     msg.description = text;      sendmessagetowx.req req = new sendmessagetowx.req();     req.scene = sendmessagetowx.req.wxscenesession;     req.transaction = string.valueof(system.currenttimemillis());     req.message = msg;      api.sendreq(req); } 

as regtowx method need create this context,but think context can not used(in ways) inside oncreate method. put in thread , problem solved.

    @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);         new thread(new runnable() {         @override         public void run() {              regtowx();         }     }).start();  } 

so try find out have done context in oncreate method, put these code out of or make code asynchronous.
