重新編譯系統應用程序

Question

因爲我正在創建自定義ROM，我想從settings.apk中刪除一些條目因爲沒有辦法隱藏XML的首選項，所以我必須從apk更改源代碼並且必須刪除來自PreferenceScreen的偏好。所以，我反編譯classes.dex與dex2jar複製的源代碼，並添加下面一行：

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

現在我的問題是，我不知道該怎麼重新編譯應用程序。我不能用Eclipse編譯它，因爲它使用了一些系統命名空間（在Eclipse中它是一個錯誤，所以我無法編譯）我該如何重新編譯應用程序？我只有* .java文件。

編輯：我加入smali文件的smali代碼：

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
