而本文将介绍android设备中已启动的服务,并推断某一服务是启动 1.依据ACTIVITY_SERVICE获取系统服务 activityManager = (ActivityManager) getSystemService...(ACTIVITY_SERVICE); 2.获取系统中正在执行的服务 runningList = activityManager.getRunningServices(30);//代表我们希望返回的服务数目大小...displaySb.append(defaultStr).append("\n"); activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE
系统内部状态信息的相关api： 得到ActivityManager ： ActivityManager activityManager = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE...isTopActivy(String cmdName){ ActivityManager manager = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE...names; } android 取当前显示的activity是什么 ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE
ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE); ComponentName cn = am.getRunningTasks
******************************************/ ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE
通过ActivityManager ActivityManager manager = (ActivityManager)context.getSystemService(ACTIVITY_SERVICE
通知栏，对话框，Toast是我们接触的三个提示框，通知栏是在系统的应用com.adnroid.systemui当中的 接触的几个Manger，getSystemService()方法得到的，参数： ACTIVITY_SERVICE
网上搜到的方法大多数都是使用下面的代码： ActivityManager am = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
返回的对象 说明 WINDOW_SERVICE WindowManager 管理打开的窗口程序 LAYOUT_INFLATER_SERVICE LayoutInflater 取得xml里定义的view ACTIVITY_SERVICE
= null) { ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
intentBatteryUsage); 16、获取进程号 ActivityManager mActivityManager = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE
while(true){ ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE
//检查设备是否支持OpenGL ES 2.0 final ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE
内存信息获取 拿到机器的可用内存信息可以参考： ActivityManager activityManager = (ActivityManager) application.getSystemService(ACTIVITY_SERVICE
layout_inflater"; public static final String ACCOUNT_SERVICE = "account"; public static final String ACTIVITY_SERVICE
返回的对象说明 WINDOW_SERVICE WindowManager 管理打开的窗口程序 LAYOUT_INFLATER_SERVICE LayoutInflater 取得xml里定义的view ACTIVITY_SERVICE
打印出来的日志都相同 1 2 3 4 5 6 7 8 9 10 ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE
----其他获取方式-------------------- ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE
剩余内存 获取设备的剩余内存大小，以及内存总量，可通过系统服务ACTIVITY_SERVICE构造ActivityManager对象，从中获得每个进程的内存使用情况。
checkSupported() : Boolean{ var supportsEs2 = false; val activityManager = getSystemService(ACTIVITY_SERVICE
