2010.06.04日志：关于android正在运行程序的关闭问题

从网上搜到的线索：

下面的代码利用Intent.CATEGORY_LAUNCHER，可以取得表示在Launcher中的所有App信息
可是如何取得正在运行状态的App信息呢？在intent里面没找到对应的定义。
希望高手指教，谢谢

1. 1:  PackageManager manager=getPackageManager();

   2:   Intent intent=new Intent(Intent.ACTION_MAIN,null);

   3:  

   4:   //在Launcher中的所有App信息--》 apps

   5:   intent.addCategory(Intent.CATEGORY_LAUNCHER);  

   6:   List<ResolveInfo> apps=manager.queryIntentActivities(intent,0);

   7:   Collections.sort(apps,new ResolveInfo.DisplayNameComparator(manager));

   2.关于开机运行的程序的获得：

   线索：

   getPackageManager().queryIntent***()可以指定Intent查循所有的Activity,其他组件类似!

2. 思考：要想让一个Activity或BroadcastReceiver在开机时启动运行，要在项目的Androidmanifest.xml中的<intent-filter>中写上<action android:name = “android.intent.action.BOOT_COMPLETED”>

所以要可以这样处理来获得开机运行的程序：

 1:  public List fetch_installed_apps() {

 2:          PackageManager packageManager = getPackageManager();

 3:  

 4:          Intent intent = new Intent(Intent.ACTION_BOOT_COMPLETED,null);//开机启动的intent

 5:          List<ResolveInfo> appsList = packageManager.queryIntentActivities(intent, 0);//搜索开机启动的intent的Activity

 6:  //        List<ResolveInfo> appsList = packageManager.queryBroadcastReceivers(intent, 0);//搜索开机启动的intent的BroadcastReceivers

 7:          list = new ArrayList<Map<String, Object>>(appsList.size());

 8:          Log.d("TAG", appsList.size()+"");

 9:          Iterator<ResolveInfo> l = appsList.iterator();

10:  

11:          while (l.hasNext()) {

12:              Map<String, Object> map = new HashMap<String, Object>();

13:              ResolveInfo app = (ResolveInfo) l.next();

14:              String packageName = app.activityInfo.packageName;// 包名

15:              String appDir = app.activityInfo.labelRes+"";// 程序的路径

16:              File appFile = new File(appDir);// 由路径创建一个File

17:              String fileSize = appFile.length() + "";// 当前程序的大小

18:              String label = "";

19:              try {

20:  //                label = getPackageManager().getApplicationLabel(app).toString();// Label

21:  //                PackageInfo pInfo = getPackageManager().getPackageInfo(

22:  //                        packageName, MODE_APPEND);

23:                  // versioncode =pInfo.versionCode+"";//版本号

24:  //                versionName = pInfo.versionName + "";// 版本名

25:              } catch (Exception e) {

26:                  Log.i("Exception", e.toString());

27:              }

28:              map = new HashMap<String, Object>();

29:              map.put("name", packageName);

30:              map.put("desc", appDir);

31:              // map.put("img", getPackageManager().getActivityIcon(g));

32:              list.add(map);

33:          }

34:          return list;

35:      }
