assets文件夹下文件或者文件夹的复制问题

Question

 AssetManager assets = this.createPackageContext(
                        "com.kxd.wsc.demo", Context.CONTEXT_IGNORE_SECURITY)
                        .getAssets();
                String[] list_x86 = assets.list("x86");
                String[] list_armeabi = assets.list("armeabi");
                String[] list_ = assets.list("");
                Log.i("list_x86", list_x86.length + "");
                Log.i("list_armeabi", list_armeabi.length + "");
                Log.i("list_", list_.length + "");
                String toAppPath_x86 = getFilesDir().getParent().toString()
                        + "/x86";
                String toAppPath_armeabi = getFilesDir().getParent().toString()
                        + "/armeabi";
                Log.i("file", toAppPath_x86);
                Log.i("file", toAppPath_armeabi);
                for (String fileName : list_x86) {
                    String to = toAppPath_x86 + "/" + fileName;
                    Log.i("filename", fileName);
                    String[] list = assets.list(fileName);
                    Log.i("list", list.length + "");
                    InputStream in = assets.open(fileName);
                    // InputStream in = new FileInputStream(file);

获取到的list集合都正常，可以看到里面额so库目录，但是没办法作为输入流，判定是否存在也是false，是否为文件夹也是false，是否是文件也是false，不知道为什么，路径什么的都试过了，相对 绝对都不行，实在是没辙了……
