23、获取app所占据的内存

public static  void getRunningAppProcessInfo(ActivityManager mActivityManager) { 
        //ActivityManager mActivityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE); 
       
        if(mActivityManager != null)
        {
            //获得系统里正在运行的所有进程 
            List<RunningAppProcessInfo> runningAppProcessesList = mActivityManager.getRunningAppProcesses(); 
           
            for (RunningAppProcessInfo runningAppProcessInfo : runningAppProcessesList) { 
                // 进程ID号 
                int pid = runningAppProcessInfo.pid; 
                // 用户ID 
                int uid = runningAppProcessInfo.uid; 
                // 进程名 
                String processName = runningAppProcessInfo.processName; 
                // 占用的内存 
                int[] pids = new int[] {pid}; 
                Debug.MemoryInfo[] memoryInfo = mActivityManager.getProcessMemoryInfo(pids); 
                int memorySize = memoryInfo[0].dalvikPrivateDirty; 
                if(processName.equals("com.huofu"))
                {
                        CommonUtils.LogWuwei(tag,"processName="+processName+",pid="+pid+"\nuid="+uid+"\nmemorySize="+memorySize/1024+"M");
                        break;
                }
                 
            } 
        }
        else
