ActivityManager(二)--获取应用所占内存大小

private void getRunningAppProcessInfo() {
mActivityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);

//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;

System.out.println("processName="+processName+",pid="+pid+",uid="+uid+",memorySize="+memorySize+"kb");
}
}
