1： 获取PackageManager 获取全部静态已安装的应用：

PackageManager pm = getPackageManager(); List
     
       infos = pm.getInstalledPackages(0);  icon  ： info.applicationInfo.loadIcon(pm) appName : info.applicationInfo.loadLabel(pm)
     

2：获取ActivityManager获取动态所有正在运行的进程

ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);List
     
       infos = am.getRunningAppProcesses(); info.processName + " ; " + info.uid + " ; " + info.pid
     

类似如下输出：
