android的Activity管理

接触android开发，不得不要考虑Activity的生命周期，对activity的管理也至关重要，不多说，贴代码：

import java.util.LinkedList;import java.util.List;import android.app.Activity;import android.app.Application;/** * activity管理 * @author Liujy * */public class KYActivityMannger extends Application {private List<Activity> mList = new LinkedList<Activity>();private List<Activity> mLogoutList = new LinkedList<Activity>();private static KYActivityMannger instance;private KYActivityMannger() {}public synchronized static KYActivityMannger getInstance() {if (null == instance) {instance = new KYActivityMannger();}return instance;}/** *  add Activity save mList * @param activity */public void addActivity(Activity activity) {mList.add(activity);}/** *  add Activity save mLogoutList * @param activity */public void addLogoutActivity(Activity activity) {mLogoutList.add(activity);}/** * 退出 */public void exit() {try {for (Activity activity : mList) {if (activity != null)activity.finish();}} catch (Exception e) {e.printStackTrace();} finally {android.os.Process.killProcess(android.os.Process.myPid());System.exit(0);}}/** * 注销 */public void logout() {try {for (Activity activity : mLogoutList) {if (activity != null)activity.finish();}} catch (Exception e) {e.printStackTrace();} finally {System.gc();}}public void onLowMemory() {super.onLowMemory();System.gc();}}

在每个activity中添加以下代码：

KYActivityMannger.getInstance().addActivity(this);KYActivityMannger.getInstance().addLogoutActivity(this);
