android - MapFragment ArcGis - The specified child already has a parent -

i'm trying display mapview arcgis in android studio. i'm using map fragments that, put in xml map , other ui stuff. putting mapview element in layout file crashes, i'm doing way:

my_main_activity.xml

<android.support.v4.widget.drawerlayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/maps_app_activity_drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" >  <!-- main content view -->  <framelayout     android:id="@+id/maps_app_activity_content_frame"     android:layout_width="match_parent"     android:layout_height="match_parent" />  <!-- navigation drawer --> <listview     android:id="@+id/maps_app_activity_left_drawer"     style="@style/drawer_listview_style"     android:layout_width="240dp"     android:layout_height="match_parent"     android:layout_gravity="start"     android:background="@android:color/darker_gray"     android:choicemode="singlechoice"     android:divider="@color/esri_gray"     android:dividerheight="1px" /> 

and framgent layout: map_fragment_layout.xml

<framelayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/map_fragment_map_container_frame_layout" android:layout_width="match_parent" android:layout_height="match_parent"> <!-- map configuration --> <com.esri.android.map.mapview     android:id="@+id/map_layout"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     initextent = "-9934033.827 1537316.31 -9933312.043 1537940.728" > <!-- xmin ymin xmax ymax --> </com.esri.android.map.mapview> 

my map fragment class holds every configuration of mapview:

@override public view oncreateview(layoutinflater inflater, viewgroup container,bundle savedinstancestate) {      mmapcontainer = (framelayout) inflater.inflate(r.layout.map_fragment_layout,container,false);      // add dynamic layer mapview (base)     // retrieve map , initial extent xml layout     mapview mapview = (mapview)mmapcontainer.findviewbyid(r.id.map_layout);     arcgisdynamicmapservicelayer basemap = new arcgisdynamicmapservicelayer(basemapurl);     mapview.addlayer(basemap);     //creates dynamic layer using service url     arcgisdynamicmapservicelayer dynamiclayer = new arcgisdynamicmapservicelayer(dynamicmapurl);     //adds layer 'mapview'     mapview.addlayer(dynamiclayer);      // set mapview allow user rotate map when part of pinch gesture.     setmapview(mapview);     mapview.zoomin();      return mmapcontainer; } 

the function setmapview configures rest of mapview options:

private void setmapview(final mapview mapview) {      mmapview = mapview;     mmapview.setesrilogovisible(false);     mmapview.enablewraparound(true);     mapview.setallowrotationbypinch(true);      // creating inflater     minflater = (layoutinflater) getactivity().getsystemservice(context.layout_inflater_service);      // setting layout params searchview , searchresult layout     mlayoutparams = new framelayout.layoutparams(layoutparams.match_parent,layoutparams.wrap_content, gravity.left | gravity.top);     mlayoutparams.setmargins(left_margin_search, top_margin_search,right_margin_search, bottom_margin_search);      // set mapview activity layout     mmapcontainer.addview(mmapview);      // displaying searchbox layout     showsearchboxlayout(); 

after debuging error shows up:

java.lang.runtimeexception: unable start activity componentinfo{zero.ucamaps/zero.ucamaps.mainactivity}: java.lang.illegalstateexception: specified child has parent. must call removeview() on child's parent first.         @ android.app.activitythread.performlaunchactivity(activitythread.java:2325)         @ android.app.activitythread.handlelaunchactivity(activitythread.java:2387)         @ android.app.activitythread.access$800(activitythread.java:151)         @ android.app.activitythread$h.handlemessage(activitythread.java:1303)         @ android.os.handler.dispatchmessage(handler.java:102)         @ android.os.looper.loop(looper.java:135)         @ android.app.activitythread.main(activitythread.java:5254)         @ java.lang.reflect.method.invoke(native method)         @ java.lang.reflect.method.invoke(method.java:372)         @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:903)         @ com.android.internal.os.zygoteinit.main(zygoteinit.java:698)  caused by: java.lang.illegalstateexception: specified child has parent. must call removeview() on child's parent first.         @ android.view.viewgroup.addviewinner(viewgroup.java:3936)         @ android.view.viewgroup.addview(viewgroup.java:3786)         @ android.view.viewgroup.addview(viewgroup.java:3727)         @ android.view.viewgroup.addview(viewgroup.java:3700)         @ zero.ucamaps.mapfragment.setmapview(mapfragment.java:313)         @ zero.ucamaps.mapfragment.oncreateview(mapfragment.java:209)         @ android.app.fragment.performcreateview(fragment.java:2053) 

i've tried removing the mapview it's parent before returning getmapview(), , still crashes. @ appreciated.

you're trying add mapview same container twice, once in java , once in xml.

in map_fragment_layout.xml, create mapview child of framelayout called map_fragment_map_container_frame_layout. that's fine.

then in setmapview, call mmapcontainer.addview(mmapview), tries add mapview again child of same framelayout. causes exception , unnecessary. remove line of code.
