public class prospectionactivity extends baseactivity {     private static final int place_picker_request = 1;     private textview mname;     private textview maddress;     private textview mattributions;     private static final latlngbounds bounds_mountain_view = new latlngbounds(             new latlng(48.8453849, 2.328134900000009), new latlng(48.866667, 2.333333));                   public double latitude;     public double longitude;     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);      framelayout contentframelayout = (framelayout) findviewbyid(r.id.content_frame); //remember framelayout area within activity_base.xml     getlayoutinflater().inflate(r.layout.activity_prospection, contentframelayout);     locationmanager service = (locationmanager) getsystemservice(location_service);     boolean enabled = service             .isproviderenabled(locationmanager.gps_provider);      if (!enabled) {         intent intent = new intent(settings.action_location_source_settings);         startactivity(intent);     }      locationmanager lm = (locationmanager)getsystemservice(context.location_service);     location location = lm.getlastknownlocation(locationmanager.gps_provider);     if (location!=null){         longitude = location.getlongitude();         latitude = location.getlatitude();         final latlngbounds coordinate = new latlngbounds(new latlng(latitude-0.000005, longitude-0.000005),new latlng(latitude+0.000005,longitude+0.000005));         mname = (textview) findviewbyid(r.id.textview);         maddress = (textview) findviewbyid(r.id.textview2);         mattributions = (textview) findviewbyid(r.id.textview3);         button pickerbutton = (button) findviewbyid(r.id.pickerbutton);         pickerbutton.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 try {                     placepicker.intentbuilder intentbuilder =                             new placepicker.intentbuilder();                     intentbuilder.setlatlngbounds(coordinate);                     intent intent = intentbuilder.build(prospectionactivity.this);                     startactivityforresult(intent, place_picker_request);                  } catch (googleplayservicesrepairableexception                         | googleplayservicesnotavailableexception e) {                     e.printstacktrace();                 }             }         });     }  }  @override protected void onactivityresult(int requestcode,                                 int resultcode, intent data) {      if (requestcode == place_picker_request             && resultcode == activity.result_ok) {          final place place = placepicker.getplace(this, data);         final charsequence name = place.getname();         final charsequence address = place.getaddress();         string attributions = (string) place.getattributions();         if (attributions == null) {             attributions = "";         }          mname.settext(name);         maddress.settext(address);         mattributions.settext(html.fromhtml(attributions));      } else {         super.onactivityresult(requestcode, resultcode, data);     } } 

} `
unfortunately, when click on button launch placepicker. nothing happens. if can me please.

here manifest

<application     android:allowbackup="true"     android:icon="@mipmap/ic_launcher"     android:label="@string/app_name"     android:supportsrtl="true"     android:theme="@style/apptheme">      <activity         android:name=".mainactivity"         android:label="@string/app_name"         android:theme="@style/apptheme.noactionbar">         <intent-filter>             <action android:name="android.intent.action.main" />              <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>     <activity         android:name=".baseactivity"         android:label="@string/app_name"         android:theme="@style/apptheme.noactionbar" />     <activity         android:name=".prospectionactivity"         android:label="@string/app_name"         android:theme="@style/apptheme.noactionbar" />     <meta-data          android:name="com.google.android.gms.version"         android:value="@integer/google_play_services_version"/>     <meta-data         android:name="com.google.android.geo.api_key"         android:value="aizasyafovxbfhflmqegopanionahiyar9jvkrk" />  </application> 

it might useful in logcat output errors tell what's going on.

looking @ manifest see haven't requested access_fine_location permission. might problem. try adding:

<uses-permission android:name="android.permission.access_fine_location" />
