重新编译系统应用程序

Question

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，因为无法用XML隐藏首选项，所以我必须从apk中更改源代码，并从PreferenceScreen中删除首选项。因此，我用classes.dex解压缩了dex2jar，复制了源代码，并添加了以下行：

getPreferenceScreen().removePreference(findPreference("toggle_wifi"));

现在我的问题是我不知道如何重新编译这个应用程序。我无法用Eclipse编译它，因为它使用了一些系统名称空间(在Eclipse中，这是一个错误，所以我无法编译)，我如何重新编译这个应用程序？我只有*.java文件。

编辑:我添加到smali文件中的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;
move-result-object v13
invoke-virtual {v12, v13}, Landroid/preference/PreferenceScreen;->removePreference(Landroid/preference/Preference;)Z

invoke-virtual {p0}, Lcom/android/settings/WirelessSettings;->getPreferenceScreen()Landroid/preference/PreferenceScreen;
move-result-object v12
const-string v13, "wifi_settings"
invoke-virtual {p0, v13}, Lcom/android/settings/WirelessSettings;->findPreference(Ljava/lang/CharSequence;)Landroid/preference/Preference;
move-result-object v13
invoke-virtual {v12, v13}, Landroid/preference/PreferenceScreen;->removePreference(Landroid/preference/Preference;)Z

invoke-virtual {p0}, Lcom/android/settings/WirelessSettings;->getPreferenceScreen()Landroid/preference/PreferenceScreen;
move-result-object v12
const-string v13, "toggle_bluetooth"
invoke-virtual {p0, v13}, Lcom/android/settings/WirelessSettings;->findPreference(Ljava/lang/CharSequence;)Landroid/preference/Preference;
move-result-object v13
invoke-virtual {v12, v13}, Landroid/preference/PreferenceScreen;->removePreference(Landroid/preference/Preference;)Z

invoke-virtual {p0}, Lcom/android/settings/WirelessSettings;->getPreferenceScreen()Landroid/preference/PreferenceScreen;
move-result-object v12
const-string v13, "bt_settings"
invoke-virtual {p0, v13}, Lcom/android/settings/WirelessSettings;->findPreference(Ljava/lang/CharSequence;)Landroid/preference/Preference;
move-result-object v13
invoke-virtual {v12, v13}, Landroid/preference/PreferenceScreen;->removePreference(Landroid/preference/Preference;)Z
