android - I have an error on my activity -

hope me solve error.

i have public class open :

@suppresswarnings("deprecation") public class addpostactivity extends appcompatactivity {   

in wich have code written, on section of map in activity appears error : "cannot resolve method getmap();"

the code : `

    mapfragment fm = (mapfragment)getfragmentmanager()      .findfragmentbyid(r.id.maps_fragment);     map = fm.getmap();      map.setmaptype(googlemap.map_type_normal);     muisettings = map.getuisettings();      muisettings.setcompassenabled(true);      muisettings.setmylocationbuttonenabled(false);` 

*i have tried replace getmap(); getmapasync(); :`

        public class addpostactivity extends fragmentactivity implements onmapreadycallback  {         @override         protected void oncreate(bundle savedinstancestate) {             super.oncreate(savedinstancestate);             setcontentview(r.layout.activity_add_post);              mapfragment fm = (mapfragment) getfragmentmanager().findfragmentbyid(r.id.maps_fragment);             fm.getmapasync(this);         }          public void onmapready(googlemap map) {                 map.setmaptype(googlemap.map_type_normal);                 muisettings = map.getuisettings();                 muisettings.setcompassenabled(true);                 muisettings.setmylocationbuttonenabled(false);         }       } 

but appears public (of second class) in red line

then how can add code of onmapreadycallback in first public class, not appears duplicate public clas , not give erros ?

xml

  <fragment android:id="@+id/maps_fragment"  android:name="com.google.android.gms.maps.mapfragment"  android:layout_width="match_parent" android:layout_height="match_parent" /> 

unable find problem could. let try these lines.

if implement onmapreadycallback need override onmapready function.

public class getlocationactivity extends appcompatactivity implements onmapreadycallback {  googlemap gmap;  @override protected void oncreate(bundle savedinstancestate) { .... ... . gmap = ((mapfragment) getfragmentmanager().findfragmentbyid( r.id.gmap)).getmap(); .. ..  }  @override public void onmapready(googlemap googlemap) {  // logic here }  } 

edited:

remove these lines code. [ remove second class]

then make first class implement onmapreadycallback.

then copy necessary variables , logic first class itself.

// remove below lines code.

public class addpostactivity extends addpostactivity implements onmapreadycallback {      private uisettings muisettings;     private googlemap map;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.add_post_activity);          mapfragment fm = (mapfragment) getfragmentmanager().findfragmentbyid(r.id.maps_fragment);         fm.getmapasync(this);     }      @override     public void onmapready(googlemap googlemap) {          map.setmaptype(googlemap.map_type_normal);         muisettings = map.getuisettings();          muisettings.setcompassenabled(true);         muisettings.setmylocationbuttonenabled(false);     }     } 

instead implement same logic in first class itself. let me know queries
