代码实现：
/** * packName 应用的包名 * 返回值 */ public static boolean isAppAlive(Context context, String packageName){ ActivityManager activityManager = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE); List<ActivityManager.RunningAppProcessInfo> processInfos = activityManager.getRunningAppProcesses(); for(int i = 0; i < processInfos.size(); i++){ if(processInfos.get(i).processName.equals(packageName)){ Log.i("NotificationLaunch", String.format("the %s is running, isAppAlive return true", packageName)); return true; } } Log.i("NotificationLaunch", String.format("the %s is not running, isAppAlive return false", packageName)); return false; }
