因为我正在创建自定义 ROM，所以我想从 settings.apk 中删除一些条目因为无法使用 XML 隐藏首选项，所以我必须从 apk 更改源代码，并且必须从 PreferenceScreen 中删除首选项。于是我classes.dex用dex2jar反编译了复制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。我不能用 Eclipse 编译它，因为它使用了一些系统命名空间（在 Eclipse 中这是一个错误，所以我无法编译） 我怎样才能重新编译应用程序？我只有 *.java 文件。
编辑：我添加到 smali 文件的 smali 代码：
invoke-virtual {p0}, Lcom/android/settings/WirelessSettings;->getPreferenceScreen()Landroid/preference/PreferenceScreen;
move-result-object v12
const-string v13, "toggle_wifi"
invoke-virtual {p0, v13}, Lcom/android/settings/WirelessSettings;->findPreference(Ljava/lang/CharSequence;)Landroid/preference/Preference;
