重新编译系统应用程序

Question

因为我正在创建自定义ROM，我想从settings.apk中删除一些条目因为没有办法隐藏XML的首选项，所以我必须从apk更改源代码并且必须删除来自PreferenceScreen的偏好。所以，我反编译classes.dex与dex2jar复制的源代码，并添加下面一行：

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

现在我的问题是，我不知道该怎么重新编译应用程序。我不能用Eclipse编译它，因为它使用了一些系统命名空间（在Eclipse中它是一个错误，所以我无法编译）我该如何重新编译应用程序？我只有* .java文件。

编辑：我加入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; 
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
