android can do a lot in the context operations, but the main function is to load and access resources. There are two context in android, one is the application context, one is the activity context, we usually pass between the various classes and methods are activity context. For example, an activity in onCreate: public void onCreate (Bundle savedInstanceState) {super.onCreate (savedInstanceState); requestWindowFeature (Window.FEATURE_NO_TITLE);. getWindow () setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); mGameView = new GameView (this); setContentView (mGameView);} the activity context is passed to the view, means that view has a reference to the activity, and thus plays a reference activity UI resource: view, resource, SensorManager so on. but this memory leak occurs if the context, it would leak a lot of memory, where the leaks mean activity gc no way to reclaim memory (the current Activity is active or not enough time to finish the recovery). Leaking an entire activity is a very easy thing. when the screen rotation, the system will destroy the current activity, save state Doudoune Moncler Femme information and then create a new one. example, we wrote an application that needs to load a lot of pictures, we do not want to rotate the screen every time when they are destroyed this image reloaded. required to achieve this simple idea is to define a static Drawable, so Activity class creates destroy it always saved in memory access speed will be soon. Achieve similar: public class myactivity extends Activity {private static Drawable sBackground; protected void onCreate (Bundle state) {super.onCreate (state); TextView label = new TextView (this); label.setText ("Leaks are bad"); if (sBackground == null) {sBackground = getDrawable (R.drawable.large_bitmap);} label.setBackgroundDrawable (sBackground) ;/ / drawable attached to Moncler K?benhavn a view setContentView (label);}} This program looks simple, but the problem is large. When the screen rotation when there will leak, that gc can not destroy activity we have said, the screen rotation when the system will destroy the current activity. But when the drawable and the associated view, drawable save the view of reference, namely sBackground save a reference label, and the label holds the activity of references. Since drawable can not be destroyed, it references and indirect references can not be destroyed, so that the system is no way to destroy the current activity, thus resulting in a memory leak. gc for this type of memory leaks is powerless. way to Moncler Jacken Damen avoid this is to avoid memory leaks activity any longer than the lifetime of the object activity, avoid references to objects on the activity leads to activity not normally be destroyed same time, we can use the application context application context associated with application of life, regardless of the activity life cycle. application context can be obtained by Context.getApplicationContext or Activity.getApplication methods. Use Application, need to be registered in the AndroidManifest.xml file that android: name = ". GApplication": avoid context-related memory leaks, remember the following: 1. Do not let the long life cycle of an object reference activity context, the object of which is to ensure a reference activity to the activity itself, the life cycle is the same . 2 for a long life cycle objects, you can use the application context (inherited class: public classGApplicationextends Application) 3. possible to use a static class (global), to avoid non-static inner classes to avoid life-cycle issues, pay attention to the inner class object reference to external changes caused by life-cycle
