[MOD] [GUIDE] AOSP lock screen with toggle - Verizon Samsung Galaxy S 4

How to enable AOSP lockscreen for the S4​
As always, for reasons of keeping things simple I use my Rom Control file to house all my MOD settings. Its easier to add and remove code and never changes with updates.
We will be working with three files:
SecSettings
framework-res
android.policy
We will begin with SecSettings
Navigate to res/values/strings and add the following:
Code:
<string name="lockscreen_title">Enable AOSP lockscreen</string>
<string name="lockscreen_summary">Choose AOSP or TW lockscreen</string>
Navigate to res/xml/rom_settings (or your xml of choice) and add the following:
Code:
<CheckBoxPreference android:title="@string/lockscreen_title" android:key="aosp_lock_enabled" android:summary="@string/lockscreen_summary" />
Navigate to smali/com/android/settings/didact/RomSettings.smali (or your settings smali of choice) and add the following:
The first lines just describe what method to add the code to. Dont copy them into the file.
Code:
.field mAospLock:Landroid/preference/CheckBoxPreference;
Code:
[B]In .method public onCreate(Landroid/os/Bundle;)V.....[/B]
:goto_4
invoke-virtual {v4, v1}, Landroid/preference/CheckBoxPreference;->setChecked(Z)V
const-string v1, "aosp_lock_enabled"
invoke-virtual {p0, v1}, Lcom/android/settings/didact/RomSettings;->findPreference(Ljava/lang/CharSequence;)Landroid/preference/Preference;
move-result-object v1
check-cast v1, Landroid/preference/CheckBoxPreference;
iput-object v1, p0, Lcom/android/settings/didact/RomSettings;->mAospLock:Landroid/preference/CheckBoxPreference;
iget-object v4, p0, Lcom/android/settings/didact/RomSettings;->mAospLock:Landroid/preference/CheckBoxPreference;
invoke-virtual {p0}, Lcom/android/settings/didact/RomSettings;->getActivity()Landroid/app/Activity;
move-result-object v1
invoke-virtual {v1}, Landroid/app/Activity;->getContentResolver()Landroid/content/ContentResolver;
move-result-object v1
const-string v5, "aosp_lock_enabled"
invoke-static {v1, v5, v3}, Landroid/provider/Settings$System;->getInt(Landroid/content/ContentResolver;Ljava/lang/String;I)I
move-result v1
if-ne v1, v2, :cond_5
move v1, v2
:goto_5
invoke-virtual {v4, v1}, Landroid/preference/CheckBoxPreference;->setChecked(Z)V
Code:
[B]in .method public onPreferenceTreeClick(Landroid/preference/PreferenceScreen;Landroid/preference/Preference;)Z[/B]
:cond_9
invoke-static {v2, v3, v0}, Landroid/provider/Settings$System;->putInt(Landroid/content/ContentResolver;Ljava/lang/String;I)Z
goto/16 :goto_0
:cond_a
iget-object v2, p0, Lcom/android/settings/didact/RomSettings;->mAospLock:Landroid/preference/CheckBoxPreference;
if-ne p2, v2, :cond_1
invoke-virtual {p0}, Lcom/android/settings/didact/RomSettings;->getActivity()Landroid/app/Activity;
move-result-object v2
invoke-virtual {v2}, Landroid/app/Activity;->getContentResolver()Landroid/content/ContentResolver;
move-result-object v2
const-string v3, "aosp_lock_enabled"
check-cast p2, Landroid/preference/CheckBoxPreference;
invoke-virtual {p2}, Landroid/preference/CheckBoxPreference;->isChecked()Z
move-result v4
if-eqz v4, :cond_b
move v0, v1
:cond_b
invoke-static {v2, v3, v0}, Landroid/provider/Settings$System;->putInt(Landroid/content/ContentResolver;Ljava/lang/String;I)Z
goto/16 :goto_0
.end method
Thats it for SecSettings. Again, you may wish to add these mods to lockscreen settings ot your own xml control. If you want to add them to lockscreen settings, have a look at my guide for the S3, it goes into how to do that. Now on to Framework-res in the next section......
AOSP Lockscreen with toggle, part 2.....framework-res​​
In this file we will be doing two things:
Centering the glowpad in your screen
adding lock targets with camera (stock only adds unlock).
Navigate to res/layout/keyguard_selector_view.xml and replace the whole file with the following:
Code:
<?xml version="1.0" encoding="utf-8"?>
<com.android.internal.policy.impl.keyguard.KeyguardSelectorView android:orientation="vertical" android:id="@id/keyguard_selector_view" android:clipChildren="false" android:clipToPadding="false" android:layout_width="fill_parent" android:layout_height="fill_parent" android:contentDescription="@string/keyguard_accessibility_slide_unlock" android:layout_maxHeight="@dimen/keyguard_security_height" android:layout_maxWidth="420.0dip"
xmlns:prvandroid="http://schemas.android.com/apk/prv/res/android"
xmlns:android="http://schemas.android.com/apk/res/android">
<FrameLayout android:gravity="center" android:layout_gravity="center" android:clipChildren="false" android:clipToPadding="false" android:layout_width="fill_parent" android:layout_height="fill_parent">
<include android:layout_width="fill_parent" android:layout_height="wrap_content" layout="@layout/keyguard_message_area" />
<View android:id="@id/keyguard_selector_view_frame" android:background="@drawable/kg_bouncer_bg_white" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_marginLeft="16.0dip" android:layout_marginRight="16.0dip" />
<include layout="@layout/keyguard_glow_pad_container" />
<include android:layout_gravity="bottom|center" android:id="@id/keyguard_selector_fade_container" android:visibility="gone" android:layout_width="fill_parent" android:layout_height="0.0dip" layout="@layout/keyguard_eca" />
</FrameLayout>
</com.android.internal.policy.impl.keyguard.KeyguardSelectorView>
Navigate to res/layout/keyguard_glow_pad_view.xml and replace the entire file with the following:
Code:
<?xml version="1.0" encoding="utf-8"?>
<com.android.internal.widget.multiwaveview.GlowPadView android:gravity="center" android:layout_gravity="center" android:orientation="horizontal" android:id="@id/glow_pad_view" android:layout_width="wrap_content" android:layout_height="wrap_content" prvandroid:innerRadius="@dimen/glowpadview_inner_radius" android:contentDescription="@string/keyguard_accessibility_slide_area" prvandroid:targetDescriptions="@array/lockscreen_target_descriptions_with_camera" prvandroid:directionDescriptions="@array/lockscreen_direction_descriptions" prvandroid:outerRingDrawable="@drawable/ic_lockscreen_outerring" prvandroid:pointDrawable="@drawable/ic_lockscreen_glowdot" prvandroid:glowRadius="@dimen/glowpadview_glow_radius" prvandroid:firstItemOffset="@integer/kg_glowpad_rotation_offset" prvandroid:magneticTargets="true" prvandroid:allowScaling="true" prvandroid:targetDrawables="@array/lockscreen_targets_with_camera" prvandroid:handleDrawable="@drawable/ic_lockscreen_handle" prvandroid:outerRadius="@dimen/glowpadview_target_placement_radius" prvandroid:vibrationDuration="20" prvandroid:snapMargin="@dimen/glowpadview_snap_margin" prvandroid:feedbackCount="1"
xmlns:prvandroid="http://schemas.android.com/apk/prv/res/android"
xmlns:android="http://schemas.android.com/apk/res/android" />
Thats it for framework-res. The last section is for android.policy
AOSP Lockscreen with toggle part 3, android.policy​
This last part will add the AOSP functionality with toggle.
Navigate to smali/com/android/internal/policy/impl/keyguard/KeyguardHostView.smali
Add the following:
Code:
.field private mAospLock:I
Find .method private getLayoutIdFor(Lcom/android/internal/policy/impl/keyguard/KeyguardSecurityModel$SecurityModeI
Replace from pswitch_0 to pswitch_1 with the following code:
Code:
:pswitch_0
iget-object v2, p0, Lcom/android/internal/policy/impl/keyguard/KeyguardHostView;->mContext:Landroid/content/Context;
invoke-virtual {v2}, Landroid/content/Context;->getContentResolver()Landroid/content/ContentResolver;
move-result-object v2
const-string v3, "aosp_lock_enabled"
invoke-static {v2, v3, v1}, Landroid/provider/Settings$System;->getInt(Landroid/content/ContentResolver;Ljava/lang/String;I)I
move-result v2
iput v2, p0, Lcom/android/internal/policy/impl/keyguard/KeyguardHostView;->mAospLock:I
iget v2, p0, Lcom/android/internal/policy/impl/keyguard/KeyguardHostView;->mAospLock:I
if-eqz v2, :cond_nocrt
const v1, 0x1090084
goto :goto_1
:cond_nocrt
const v1, 0x1090091
goto :goto_1
:pswitch_1
Thats it. Recompile and push the files to your phone. Enjoy AOSP Lockscreen.
I am currently working to add more functions such as weather and added shortcuts so stay tuned....
Thanks Button!!

Nice!! I assume we would need to add the rom control bits you talk about. Where are they? They are not already there are they?

No, you don't have to. I just geared this tutorial around the idea that you would. You can add it to any XML you want, just have to follow the flow of the xml you add it to.

Looks cool! Can you post some screenshots?

awesome job like always thanks

I will tomorrow, in bed now. Unless someone else has it going and would like to post a pic.

Nice work as always my man.
In order to get the AOSP lock screen working I had to set "Screen lock" to "Swipe" and "Unlock effect" to "None" in Lock screen settings.
Is that how it works or did I screw something up?

It works for me no matter how I have the unlock effect.

---

Is this the actual aosp lockscreen or just the similar one that has the fixed unlock shortcuts?

Hmmmm...maybe I need to go through this again....
Edit:
Works perfect. Just needed to clean up some code.

In keyguard_selector_view.xml you can change the size and position of the ring. You just need to play around a little.

Well i just play around, it's back to normal again after playing with android.policy since play with keyguard_selector_view.xml didn't works
