不用Root就对App进行查看分享的工具

今天看到一个项目，从图中可以看到，无需root进行app的一些操作，从中我们可以获取一些常规信息

1，获取应用最近使用的pkg信息

public static List getUsageStatsList(Context context){UsageStatsManager usm = getUsageStatsManager(context);Calendar calendar = Calendar.getInstance(); long endTime = calendar.getTimeInMillis(); long startTime = calendar.getTimeInMillis()-60*60*1000;List usageStatsList = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY,startTime,endTime); return usageStatsList;}

2，通过ProcessManage获取正在运行app包信息列表

public static List getRunningAppProcessInfo(Context context) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {List runningAppProcesses = AndroidProcesses.getRunningAppProcesses();List appProcessInfos = new ArrayList<>(); for (AndroidAppProcess process : runningAppProcesses) {RunningAppProcessInfo info = new RunningAppProcessInfo(process.name, process.pid, null);info.uid = process.uid;// TODO: Get more information about the process. pkgList, importance, lru, etc.appProcessInfos.add(info);}return appProcessInfos;}ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); return am.getRunningAppProcesses();}
