About NICS Themer
NICS Themer works with Xposed App & X-Themer Engine. It is intended to serve the same purpose as T-Mobile/CM10 Theme Engine. NICS lets you to create own themed apk, my friend neroyoung first develop the idea of it & implemented in his NICS Rom. I am writing a complete guide here to share with you cause I think it's a really useful thing
Requirement
1. X-posed App by rovo89
2. X-Themer Engine by ruqqq
3. My Base.apk
4. Virtuous Ten Studio (VTS) - Official Website
5. A Editing Software like Paint.NET - Download Link
Note: # 1,2,3 are available in 2nd post attachment
Note: for more information about X-posed App & X-Themer Engine visit the official thread.
Main Guide
1. Download & install VTS in default directory & place Base.apk in Desktop
2. Open VTS & click on File>New Project (Right hand top corner). Click on Import tab & locate the Base.apk from Desktop, then click Import. Now click on Project tab & you will see the Project name as "Base", give a Solution name or just name it to "Base" as well. Then press Ok. For better understanding I am providing screenshot with serial number to the task you have to do.

3. You will see now task is running & in some seconds your apk will be decompile successfully. It will look like this, minimize VTS

4. Now go to there where VTS keeps projects. For me it is in C:\Documents and Settings\USER\My Documents\Virtuous Ten Studio\Projects
Now go inside your project "Base\Data folder.
Inside drawable folder there is a png which is the icon of the apk
Inside xml folder there is a redirection.xml, we have to redirect the packages which we will theme & other xmls need to be write here.
Go inside values folder & delete Public.xml
5. Now lets begin with the guide. As framework, systemUI & Settings are the three most important component of Rom, I will show how to theme & redirect them.
6. Now, 1st decompile Settings.apk which you want to theme to get the resources & pngs from there. Use another tool like Apktool, Xda Auto Apktool or Apk Multitool. Here is a Guide on Apk Multi Tool.
7. Open AndroidManifest.xml of Settings.apk, we need android version & package name of it. Like for my Settings.apk it is
android:versioncode="15"
pacakge="com.android.settings" Remember those or note it down somewhere

Also go to the drawable-hdpi folder of Settings.apk & copy the pngs you want to theme. Note that, according to your phone this drawable folder can be drawable-ldpi/mdpi/hdpi/xhdpi. So according to it make a drawable folder in Data\Res of the decompiled Base.apk
I am creating it in Data\res\drawable-hdpi, & adding the pngs in the folder which I have copied from Settings.apk
8. Now, inside the drawable-hdpi folder rename the pngs with anything you like. To avoid all conflicts I would suggest to add the package name infront of every png. For example, I have taken three pngs from settings. Here are the original & renamed name of them--
ic_settings_wireless.png -------------- com_android_settings_ic_settings_wireless.png
ic_settings_bluetooth2.png ---------- com_android_settings_ic_settings_bluetooth2.png
ic_settings_data.png ------------------- com_android_settings_ic_settings_data.png
9. Now go to xml folder & write a new xml named "com_android_settings.xml" & write according to how many pngs you have taken,
Code:
<?xml version="1.0" encoding="utf-8"?>
<resource-redirections>
<item name="drawable/ic_settings_bluetooth2">@drawable/com_android_settings_ic_settings_bluetooth2</item>
<item name="drawable/ic_settings_data_usage">@drawable/com_android_settings_ic_settings_data_usage</item>
<item name="drawable/ic_settings_wireless">@drawable/com_android_settings_ic_settings_wireless</item>
</resource-redirections>
Here, item name="drawable/ic_settings_bluetooth2" - is the original png name which is inside Settings.apk
@drawable/com_android_settings_ic_settings_bluetooth2 - is the renamed pngs which will replace the original png
So it will look like this,

10. Now decompile SystemUI.apk the same way & get android version & package name from AndroidManifest.xml. For me it is,
android:versioncode="15"
package="com.android.systemui"
Copy the pngs you want to edit from drawable folder & add it to Data\res\drawable-hdpi folder of Base.apk. Now rename the pngs you have copied with the package name attached to the front. Like for a png the original & renamed is-
stat_bluetooth_on.png ---------- com_android_systemui_stat_bluetooth_on.png
11. Write a new xml in xml folder named "com_android_systemui.xml" & write according to how many pngs you have taken-
Code:
<?xml version="1.0" encoding="utf-8"?>
<resource-redirections>
<item name="drawable/stat_2g3g_off">@drawable/com_android_systemui_stat_2g3g_off</item>
<item name="drawable/stat_2g3g_on">@drawable/com_android_systemui_stat_2g3g_on</item>
<item name="drawable/stat_3g_on">@drawable/com_android_systemui_stat_3g_on</item>
<item name="drawable/stat_airplane_on">@drawable/com_android_systemui_stat_airplane_on</item>
<item name="drawable/stat_bluetooth_on">@drawable/com_android_systemui_stat_bluetooth_on</item>
<item name="drawable/stat_brightness_auto">@drawable/com_android_systemui_stat_brightness_auto</item>
<item name="drawable/stat_brightness_mid">@drawable/com_android_systemui_stat_brightness_mid</item>
<item name="drawable/stat_brightness_on">@drawable/com_android_systemui_stat_brightness_on</item>
<item name="drawable/stat_data_on">@drawable/com_android_systemui_stat_data_on</item>
<item name="drawable/stat_flashlight_on">@drawable/com_android_systemui_stat_flashlight_on</item>
<item name="drawable/stat_gps_on">@drawable/com_android_systemui_stat_gps_on</item>
<item name="drawable/stat_lock_screen_on">@drawable/com_android_systemui_stat_lock_screen_on</item>
<item name="drawable/stat_orientation_on">@drawable/com_android_systemui_stat_orientation_on</item>
<item name="drawable/stat_reboot">@drawable/com_android_systemui_stat_reboot</item>
<item name="drawable/stat_ring_on">@drawable/com_android_systemui_stat_ring_on</item>
<item name="drawable/stat_screen_timeout_1m">@drawable/com_android_systemui_stat_screen_timeout_1m</item>
<item name="drawable/stat_screen_timeout_2m">@drawable/com_android_systemui_stat_screen_timeout_2m</item>
<item name="drawable/stat_screen_timeout_10m">@drawable/com_android_systemui_stat_screen_timeout_10m</item>
<item name="drawable/stat_screen_timeout_30m">@drawable/com_android_systemui_stat_screen_timeout_30m</item>
<item name="drawable/stat_screen_timeout_15s">@drawable/com_android_systemui_stat_screen_timeout_15s</item>
<item name="drawable/stat_screen_timeout_30s">@drawable/com_android_systemui_stat_screen_timeout_30s</item>
<item name="drawable/stat_shutdown">@drawable/com_android_systemui_stat_shutdown</item>
<item name="drawable/stat_sync_on">@drawable/com_android_systemui_stat_sync_on</item>
<item name="drawable/stat_wifi_on">@drawable/com_android_systemui_stat_wifi_on</item>
</resource-redirections>

12. Now decompile framework-res.apk get the package name & android version from AndroidManifest.xml & get the pngs from drawable folder & add them in Data\res\drawable-hdpi folder of Base.apk. My framework's package & version is -
android:versioncode="15"
package="android"
Now rename the framework-res pngs with package name "android" or like I have done. The original & renamed png name is like this for me-
switch_bg_on_disabled_holo_dark.png ------------ framework_res_switch_bg_on_disabled_holo_dark.png
Now open a new xml in xml folder named "android.xml" & write according to how many pngs you have taken to modify
Code:
<?xml version="1.0" encoding="utf-8"?>
<resource-redirections>
<item name="drawable/switch_bg_on_disabled_holo_dark">@drawable/framework_res_switch_bg_on_disabled_holo_dark</item>
<item name="drawable/switch_bg_on_disabled_holo_light">@drawable/framework_res_switch_bg_on_disabled_holo_light</item>
<item name="drawable/switch_bg_on_holo_dark">@drawable/framework_res_switch_bg_on_holo_dark</item>
<item name="drawable/switch_bg_on_holo_light">@drawable/framework_res_switch_bg_on_holo_light</item>
<item name="drawable/switch_thumb_disabled_focused_holo">@drawable/framework_res_switch_thumb_disabled_focused_holo</item>
<item name="drawable/switch_thumb_focused_holo">@drawable/framework_res_switch_thumb_focused_holo</item>
</resource-redirections>

Note that for .9 pngs we won't add .9 to the xml
13. Open redirections.xml in xml folder & we have to write all the package redirections here. In my case I have three packages to redirect.
for Settings --
Code:
<package-redirections android:name="com.android.settings" android:resource="@xml/com_android_settings" android:minSdkVersion="15" />
Code:
<package-redirections android:name="com.android.systemui" android:resource="@xml/com_android_systemui" android:minSdkVersion="15" />
Code:
<package-redirections android:name="android" android:resource="@xml/android" android:minSdkVersion="15" />
android:resources is the xml from where png's will be redirected & replaced
android:minSdkVersion is the android:versioncode which we got from the main packages
So, the complete redirections.xml is may case will be -
Code:
<?xml version="1.0" encoding="utf-8"?>
<theme-redirections
xmlns:android="http://schemas.android.com/apk/res/android" xmlns:pluto="http://www.w3.org/2001/pluto.html">
<package-redirections android:name="com.android.settings" android:resource="@xml/com_android_settings" android:minSdkVersion="15" />
<package-redirections android:name="com.android.systemui" android:resource="@xml/com_android_systemui" android:minSdkVersion="15" />
<package-redirections android:name="android" android:resource="@xml/android" android:minSdkVersion="15" />
</theme-redirections>
Also, Remove "/" from the 3rd end of the line. So the 3rd line will be,
Code:
xmlns:android="http://schemas.android.com/apk/res/android" xmlns:pluto="http://www.w3.org/2001/pluto.html">

14. Now go to drawable-hdpi folder where all the renamed pngs are. Open them with Paint.NET & change hue/saturation to the color you want to theme them. crtl+shift+U gives you the option in Paint.NET. When theming is done save all pngs. My drawable-hdpi folder looks like this-

15. Now check once again in Data\res folder.
In drawable folder there should be icon.png which will be the icon for your apk
In values folder there will be nothing as we have deleted public.xml earlier
In xml folder there should be redirections.xml with other xmls you have created
In drawable hdpi folder there will be all the renamed & themed pngs
16. Now maximize VTS window & open AndroidManifest.xml of the Base.apk. In android:label write something you want it to be shown as the apk name. In package name give name according to your color theme. Like for me it is "saqib.themer.green". If you make another one which is orange in color name it to "saqib.themer.orange" so that it doesn't replace the earlier apk when installing. After this, save the xml. For better understanding, I have marked screenshot with serial number-

When you are done press "Build all", it will run a process & create your new apk. CONGRATULATIONS :good: now you have successfully built your own themed apk. Get it from Data\Binary folder of VTS Project.
