jni中获取系统所有进程

Question

mActivityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);

    List<ActivityManager.RunningAppProcessInfo> appProcessList = mActivityManager
            .getRunningAppProcesses();

    for (ActivityManager.RunningAppProcessInfo appProcessInfo : appProcessList) {
        String[] packageList = appProcessInfo.pkgList;

        for (String pkg : packageList) {
            Log.i("tag", "packageName " + pkg );
        }
        这么几句代码怎么在jni中实现啊啊求教。。主要是List<ActivityManager.RunningAppProcessInfo>这个不知道在jni中怎么写。
