first question here , pretty knew android development excuse me. part of app add button can restart systemui, doing following code. @override public void onclick(view v) { activitymanager activitymanager = (activitymanager)getapplicationcontext().getsystemservice(context.activity_service); activitymanager.killbackgroundprocesses("com.android.systemui"); } i have gave application su permission following code public process p; { try { p = runtime.getruntime().exec("su"); } catch (ioexception e) { e.printstacktrace(); } } many in advance. you should have permission kill_background_processes able call method. su doesn't play role here, because using android's framework operation. if use busybox kill process, need su. generally, not idea kill systemui, though.

i have map created using google maps api, , i'd restrict panning 1 globe; default can pan continuously east/west, map repeats endlessly. i'm trying use henningj's solution posted this question var allowedbounds = new google.maps.latlngbounds( new google.maps.latlng(85, -180), new google.maps.latlng(-85, 180) ); lastvalidcenter = map.getcenter(); google.maps.event.addlistener(map, "center_changed", function() { if (allowedbounds.contains(map.getcenter())) { lastvalidcenter = map.getcenter(); return; } map.panto(lastvalidcenter); }); what have allows no panning whatsoever, call 'contains' fails. if log map.getcenter() looks sensible enough, think(?!): object { a: 54.683366, f: 25.31663500000002 } can see i'm doing wrong? you have allowedbounds defined incorrectly. should (from the documentation ): latlngbounds(sw?:latlng, ne?:latlng) constructs rectangle points @ south-west , north-east
