[GUIDE][HOW TO] Toggle to choose AOSP Lockscreen **11DEC** - Galaxy S II Android Development

For TouchWiz Jelly Bean Roms (LSJ)
This is a noob proof guide, very easy to do, and made to involve less :cond_ possible.
Is not a clean guide for developers, infact i will use existing parts of code (not used) to make the toggle.
Obviously, if u are a developer and have a little experience with smali code language and patience with cond you can figure this out easily
requirements:
-apktool use (i won t teach u how to use apktool, i assume u can use it)
-attention
this tutorial is made on 2 parts:
-create a switch to change circle lockscreen with aosp lockscreen
-create a toggle to set the aosp lockscreen when checked
ready?
PART 1
We need to decompile android.policy.jar for first.
navigate: smali/com/android/internal/policy/impl/LockPatternKeyguardView.smali
look for .method createLockScreen()Landroid/view/View; and add the red lines
Code:
.method createLockScreen()Landroid/view/View;
.registers 7
.prologue
.line 1319

first part is done
recompile and push it on /system/framework
PART 2
this is the not clean part, i have not created new codes for a toggle, but i used an unused code with the form i needed (checkbox preference).
I decompiled SecSettings.apk /smali/com/android/settings/LockscreenSettings.smali
the unused code i used is "mSayCommand" one, infact has the checkbox preference form i needed as we can see
Code:
.field private mSayCommand:Landroid/preference/CheckBoxPreference;
ok let s start second part, we need to change all "mSayCommand" to "mAospLock" and change the keyword from "wake_up_lock_screen" to "aosp_lock" in order to recall the first part of the mod we made in android.policy.jar
red part is what we add, and purple what we delete.
Code:
[COLOR="Red"].field private mAospLock:Landroid/preference/CheckBoxPreference;[/COLOR]
.field private mCameraShortCut:Landroid/preference/SwitchPreferenceScreen;
.field private mClock:Landroid/preference/CheckBoxPreference;
.field private mDualclock:Landroid/preference/SwitchPreferenceScreen;
.field private mHelpText:Landroid/preference/CheckBoxPreference;
.field private mInformationTicker:Landroid/preference/SwitchPreferenceScreen;
.field private mInkEffect:Landroid/preference/PreferenceScreen;
.field mInkEffectSummary:[I
.field private mLockPatternUtils:Lcom/android/internal/widget/LockPatternUtils;
.field private mLockScreenShortcut:Landroid/preference/SwitchPreferenceScreen;
.field private mMotionDialog:Landroid/app/AlertDialog;
.field private mRippleEffect:Landroid/preference/CheckBoxPreference;

as u can see I left untouched keyword "say_your_wakeup", it s not a wrong writing, i left it and i will use that keyword in future steps.

we delete this part of code to make the option visible, infact i said we re using an unused part of code, and has been hidden from preference screen.

smali part is done, and now the toggle is set and working
last part is to edit our unused part of the code in res/xml folder, lockscreen_settings.xml
Code:
[COLOR="DarkOrchid"]<CheckBoxPreference android:title="@string/samsung_unlock_option_say_your_wakeup_command_to_unlock_screen" android:key="say_your_wakeup" android:summary="@string/wakeup_in_lockscreen_summary" />
[/COLOR]
[COLOR="Red"]<CheckBoxPreference android:title="@string/your_string" android:key="say_your_wakeup" android:summary="@string/your_summary_string" />[/COLOR]
asu can see we have again the keyword i said before "say_your_wakeup" , if u want u can change it, but change it in the smali part too if not the toggle won t work.
Now simply add the strings in /res/values/strings.xml
Code:
<string name="your_string">AOSP Lockscreen</string>
<string name="your_summary_string">Original Jelly Bean Lockscreen</string>
that s it.
easy and noob proof
and this is the result

Heyy,
Great tut! Thanks a lot!
I'm trying to get this to work on LP9
Button shows up correctly in settings, but I get a little compiling error of policy.jar.
The error I get is an undefined "goto_14" in line 3008.
There's 2 "goto_14" 's in LockPatternKeyguardView...
The one you pointed out and this seconde one in line 3008...
So I also changed the second one in "goto_1e" and after that the .dex compiles without errors...
Phone starts up with AOSP Lockscreen, but after that a bootloop...
Could you have a look at LP9's LockPatternKeyguardView.smali?
Here it is with the changes made to it, following exactly your tut:
http://dl.dropbox.com/u/25779832/SGS2/ALLES ICS/LockPatternKeyguardView.smali
Thanks a lot in advance for looking into it!

You're the man!!
Will let you know within 10 minutes
EDIT:
The good news: It doesn't give bootloop anymore!!
The bad news: It stays on AOSP Lockscreen. Doesn't matter if I untick the aosp toggle or not, stays on aosp lockscreen.
Even a reboot doesn't change it...
Will try tommorow again, will start all over and make the toggle in settings. Maybe something went wrong over there....
Thanks very much for you help though, tommorow I'll report back ok?

Mirko, I believe you've left out a part of the patch. We are adding a brand new setting, so you need to add the code to handle when it's clicked (usually in onPreferenceTreeClick) and thus save the global setting (ultimately a call to putInt).

yay u r right jeboo, in fact i wrote that this was for LPF only, and i wanted not to make a full how to for rearrange that mod for different bases.
I have really few few few time, and i realize i can t manage a thread with several requests or specific helpings.
I read what shoman94 told in ur thread, and maybe it should be better to give to you the honor to talk about this mod, what do u think about?
Let me know asap mate
