因为我正在创建一个自定义ROM我想从settings.apk中删除一些条目因为无法用XML隐藏首选项我必须从apk更改源代码并且必须从中删除首选项PreferenceScreen。所以我用dex2jar反编译classes.dex复制了源代码并添加以下行：
getPreferenceScreen().removePreference(findPreference("toggle_wifi"));
现在我的问题是我不知道如何重新编译应用程序。我无法用Eclipse编译它，因为它使用了一些系统命名空间（在Eclipse中它是一个错误所以我无法编译）我如何重新编译应用程序？我只有* .java文件。
编辑：我添加到smali文件的smali代码：

move-result-object v12
const-string v13, "toggle_wifi"
