本篇文章主要介绍了"获取Android正在运行的任务和服务",主要涉及到获取Android正在运行的任务和服务方面的内容,对于获取Android正在运行的任务和服务感兴趣的同学可以参考一下。

检测某ActivityUpdate是否在当前Task的栈顶 public static boolean isTopActivy(String cmdName, Context context) { ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); List<RunningTaskInfo> runningTaskInfos = manager.getRunningTasks(Integer.MAX_VALUE); String cmpNameTemp = null; if (null != runningTaskInfos) { cmpNameTemp = (runningTaskInfos.get(0).topActivity).toString(); } if (null == cmpNameTemp) { return false; } return cmpNameTemp.equals(cmdName); } 判断Android应用是否在前台 public static boolean isAppOnForeground(Context context) { ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); String packageName = context.getPackageName(); List<RecentTaskInfo> appTask = activityManager.getRecentTasks(Integer.MAX_VALUE, 1); if (appTask == null) { return false; } if (appTask.get(0).baseIntent.toString().contains(packageName)) { return true; } return false; } 获取Android手机内安装的所有桌面 private static List<String> getAllTheLauncher(Context context) { List<String> names = null; PackageManager pkgMgt = context.getPackageManager(); Intent it = new Intent(Intent.ACTION_MAIN); it.addCategory(Intent.CATEGORY_HOME); List<ResolveInfo> ra = pkgMgt.queryIntentActivities(it, 0); if (ra.size() != 0) { names = new ArrayList<String>(); } for (int i = 0; i < ra.size(); i++) { String packageName = ra.get(i).activityInfo.packageName; names.add(packageName); } return names; } Android 判断程序前后台状态 public static boolean isLauncherRunnig(Context context) { boolean result = false; List<String> names = getAllTheLauncher(context); ActivityManager mActivityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); List<ActivityManager.RunningAppProcessInfo> appList = mActivityManager.getRunningAppProcesses(); for (RunningAppProcessInfo running : appList) { if (running.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND) { for (int i = 0; i < names.size(); i++) { if (names.get(i).equals(running.processName)) { result = true; break; } } } } return result; }
