Exit from google maps intent in android -

i implementing custom turn-by-turn navigation in android application. achieve this, have started activity mainactivity using intent uses intent.action_view action , "google.navigation:q" uri string.the google maps navigation page loaded in app.

but, don't know how gracefully exit page. if use button press, takes 4 button clicks display main activity screen. there possibility place "exit" button in page.

i have tried "onactivityforresult" , "onbackpressed" destroying google maps screens. none of works. please provide suggestions go further.

i know pretty late answer maybe can someone.

you cannot come google map activity/app on single press need create floating view/widget ola/uber after proper implementation. here implementation.

first user go map app youractivity. in activity ask permission system_alert_window (draw over, sdk > marshmallow) on click of view. launch google map service created create floating icon.

class youractivity extends appcompatactivity{  private getfloatingiconclick mgetserviceclick; public static boolean isfloatingiconservicealive = false;  oncreate(){     mgetserviceclick = new getfloatingiconclick();      somebtn.onclick(){         askdrawoverpermission();     } }  private class getfloatingiconclick extends broadcastreceiver {      @override     public void onreceive(context context, intent intent) {         intent selfintent = new intent(youractivity.this, youractivity.class);         selfintent.setflags(intent.flag_activity_reorder_to_front | intent.flag_activity_single_top                 | intent.flag_activity_clear_top);         startactivity(selfintent);     } }  private void askdrawoverpermission() {     if (build.version.sdk_int < build.version_codes.m) {         // if os pre-marshmallow create floating icon, no permission needed         createfloatingbackbutton();     } else {         if (!settings.candrawoverlays(this)) {             // asking draw_over permission in settings             intent intent = new intent(settings.action_manage_overlay_permission,                     uri.parse("package:" + getapplicationcontext().getpackagename()));             startactivityforresult(intent, req_code_draw_over);         } else {             createfloatingbackbutton();         }     } }  // starting service creating floating icon on map private void createfloatingbackbutton() {     intent iconserviceintent = new intent(youractivity.this, floatingovermapiconservice.class);     iconserviceintent.putextra("ride_id", str_rideid);      intent navigation = new intent(intent.action_view, uri             .parse("google.navigation:q=" + lat_dest + "," + lng_dest + "&mode=d"));     navigation.setpackage("com.google.android.apps.maps");     startactivityforresult(navigation, 1234);      startservice(iconserviceintent); }  @targetapi(build.version_codes.m) @override protected void onactivityresult(int requestcode, int resultcode, intent data) {     if (requestcode == req_code_draw_over) {         // permissions settings don't provide callbacks, hence checking again permission         // can draw our floating without asking user click on clicked view         // again         if (settings.candrawoverlays(this)) {             createfloatingbackbutton();         } else {             //permission not provided user, task             //globalvariables.alert(mcontext, "this permission necessary application's functioning");         }     } else if (requestcode == 1234) {         // no result returned google map, google don't provide apis or documentation         // it.     } else {         super.onactivityresult(requestcode, resultcode, data);     } } }

floating icon xml:-
