config class

package com.example.widget;  import android.app.activity; import android.app.pendingintent; import android.appwidget.appwidgetmanager; import android.content.intent; import android.content.sharedpreferences; import android.os.bundle; import android.view.view; import android.view.view.onclicklistener; import android.widget.adapterview; import android.widget.adapterview.onitemselectedlistener; import android.widget.button; import android.widget.remoteviews; import android.widget.spinner;  public class config extends activity {  private config context; private int widgetid ; appwidgetmanager manager; remoteviews views; spinner lang_spinner; string lang; button apply;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.config);     setresult(result_canceled);      // set fields     context = this;     manager = appwidgetmanager.getinstance(context);     views = new remoteviews(context.getpackagename(), r.layout.main);      // start preferences object     sharedpreferences apppreferences = context.getsharedpreferences("widget_preferences", 0);     final sharedpreferences.editor appeditor = apppreferences.edit();      // widget id     bundle extras = getintent().getextras();     if (extras != null) {         widgetid = extras.getint(appwidgetmanager.extra_appwidget_id,                  appwidgetmanager.invalid_appwidget_id);     }      // functionality apply language     lang_spinner = (spinner) findviewbyid(r.id.spinnerlang);     lang_spinner.setonitemselectedlistener(new onitemselectedlistener() {         @override         public void onitemselected(adapterview<?> arg0, view arg1,                 int arg2, long arg3) {             lang = lang_spinner.getselecteditem().tostring();             if (lang.equals("espanol")){                 main.widget_text = getresources().getstring(r.string.widget_text_es);                 appeditor.putstring("wt"+widgetid, getresources().getstring(r.string.widget_text_es)).commit();             } else if (lang.equals("english")) {                 main.widget_text = getresources().getstring(r.string.widget_text_en);                 appeditor.putstring("wt"+widgetid, getresources().getstring(r.string.widget_text_en)).commit();             }         }          @override         public void onnothingselected(adapterview<?> arg0) {             appeditor.putstring("wt"+widgetid, getresources().getstring(r.string.widget_text_en)).commit();         }     });       // apply settings     apply = (button) findviewbyid(r.id.apply);     apply.setonclicklistener(new onclicklistener() {          public void onclick(view v) {             // send pending intent textview, able click reconfigure             intent intent = new intent(context, config.class);             pendingintent piconfig = pendingintent.getactivity(context, 0, intent, 0);             views.setonclickpendingintent(r.id.widgettext, piconfig);              // set text             views.settextviewtext(r.id.widgettext, main.widget_text);              // commit changes preferences object             // appeditor.commit();              // update widget             manager.updateappwidget(widgetid, views);              // return ok             intent result = new intent();             result.setaction(appwidgetmanager.action_appwidget_update);             result.putextra(appwidgetmanager.extra_appwidget_id, widgetid);             setresult(result_ok, result);             finish();         }     }); } } 

main class

package com.example.widget;   import android.appwidget.appwidgetmanager; import android.appwidget.appwidgetprovider; import android.content.componentname; import android.content.context; import android.content.intent; import android.content.sharedpreferences; import android.preference.preferencemanager; import android.widget.remoteviews;  public class main extends appwidgetprovider {  // text displayed on widget static string widget_text; int widgetid; remoteviews views;  @override public void onupdate(context context, appwidgetmanager appwidgetmanager, int[] appwidgetids) {     super.onupdate(context, appwidgetmanager, appwidgetids);      (int = 0; < appwidgetids.length; i++) {         widgetid = appwidgetids[i];          // text preferences         sharedpreferences quotepreferences = preferencemanager.getdefaultsharedpreferences(context);         widget_text = apppreferences.getstring("wt"+widgetid, "no text yet.");          // update view         views = new remoteviews(context.getpackagename(), r.layout.main);         views.settextviewtext(r.id.widgettext, widget_text);         appwidgetmanager.updateappwidget(widgetid, views);     } }   @override public void onreceive(context context, intent intent) {     // todo auto-generated method stub     super.onreceive(context, intent); } } 

currently onreceive void, i've tried below no avail.

@override public void onreceive(context context, intent intent) {     // todo auto-generated method stub     super.onreceive(context, intent);     appwidgetmanager manager = appwidgetmanager.getinstance(context);     componentname thiswidget = new componentname(context.getpackagename(), main.class.getname());     int [] appwidgets = manager.getappwidgetids(thiswidget);     onupdate(context, manager, appwidgets); } 

manifest

    <receiver android:name="com.example.widget.main">         <intent-filter>             <action android:name="android.appwidget.action.appwidget_update"/>         </intent-filter>         <meta-data android:name="android.appwidget.provider"             android:resource="@xml/widget"/>     </receiver>      <activity android:name="com.example.widgetconfig" android:theme="@android:style/theme.dialog">         <intent-filter>             <action android:name="android.appwidget.action.appwidget_configure"/>             <action android:name="android.appwidget.action.appwidget_update"/>         </intent-filter>     </activity> 

thanks again
