Android Phones have a lot of built-in sensor such as gyro, proximity and accelerometer. Using Accelerometer in Android is a known thing. For listening sensors, class or service needs a SensorEventListener implementation. An Activity is only exists when you are seeing it. When phone enters standby mode, activity which was recently active frozen and restored whenever needed. While this frozen time, activity doesn’t run. Because of that it doesn’t need sensor updates. And Android stop to listen some sensors for power management.
Services have this condition like classes (activity). In contrast to class, a service run every time, even when phone is in standby mode. Therefore Services needs sensor updates for some situations. But android stop to listen some sensor(accelerometer) in some different phones.
There is a solution for that. This is not an exact solution but it work with a lot of phones.
With a BroadcastReceiver listenIntent.ACTION_SCREEN_OFFand register sensor listener a…
When an app use map and design some layout on this map (TextView, Button or image), developer needs to change position of default buttons of map view. (MyLocationButton, ZoomControl or compass...) As far as i know, there are two possible way for changing position of myLocationButton's position.
1- * - Disable it
* - Create new button programmatically
* - Add animateCamera(toCurrentLocation) to onClickListener of this button
* - And place it wherever you want
But if you don't want to write all that there is a hack for that.
2 - * - findViewById() of hardcoded button with; ZoomControl id =0x1MyLocation button id =0x2
* - And do whatever you want: // Find map fragment SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
Google just released a new version of Android Support Library with SwipeRefreshLayout. It is pull to refresh layout based on Google Now, not Gmail. Before this release most of android developers use PullToRefresh library from Chris Banes (Special thanks to him for great libraries and android development tips) But with the recent release of Google, Chris drop his support to own library - PullToRefresh.  We have SwipeRefreshLayout now it is simple to use with a few line of codes.
Step One: Install Update your Android Support Library in Android SDK manager and make sure you have version 19.1. Then right click on project and select "Android Tools->Add Support Library". After instaltion your project has brand new support library.
