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
         {
             CommonUtils.LogWuwei(tag, "mActivityManager is null");
         }

     }
