pratyush.creed · Jul 2, 2012

Well, this a very simple guide on adding 6 lockscreen mod to your rom.

Files To be downloaded :
1. android.policy.zip
2. Lidroid-res.apk
3. Lidroid-Parts

Files to be Affected :

1. android.policy.jar
2. systemui.apk (only if you have added 14 status bar toggles before)

Steps :

-Pullout android.policy.jar from '/system/framework' (Must be Deodexed)
-Decompile it (Please dont expect a guide on how to decompile)
-Extract the android.policy.zip file
-copy the smali folder to directory where you decompiled your android.policy.jar

-Now open this file android.policy.jar.out\smali\com\android\internal\policy\impl\KeyguardUpdateMonitor.smali and make the following changes :

-At the begining after '#annonations' search for this line "Lcom/android/internal/policy/impl/KeyguardUpdateMonitor$AirplaneModeChangeCallback;"

after that add this line

Code:

Lcom/android/internal/policy/impl/KeyguardUpdateMonitor$MediaStateCallback;,

-Now find this line ".field private mLockscreenWallpaperDrawable:Landroid/graphics/drawable/Drawable;"

-Below it paste this line

Code:

.field private mMediaCallbacks:Ljava/util/ArrayList;
    .annotation system Ldalvik/annotation/Signature;
        value = {
            "Ljava/util/ArrayList",
            "<",
            "Lcom/android/internal/policy/impl/KeyguardUpdateMonitor$MediaStateCallback;",
            ">;"
        }
    .end annotation
.end field

-Find this line ".field private mWallpaperModeValue:I"

and jus below paste this

Code:

.field private timezone:Ljava/lang/String;

-Now find this method ".method private handleSimStateChange(Lcom/android/internal/policy/impl/KeyguardUpdateMonitor$SimArgs

V"

and above it paste this :

Code:

.method private handleMediaUpdate(IILandroid/net/Uri;)V
    .locals 5
    .parameter "isPlaying"
    .parameter "isStop"
    .parameter "mediaUri"

    .prologue
    const/4 v4, 0x0

    const/4 v3, 0x1

    .line 467
    if-ne p1, v3, :cond_0

    move v0, v3

    .line 468
    .local v0, bIsPlaying:Z
    :goto_0
    if-ne p2, v3, :cond_1

    move v1, v3

    .line 470
    .local v1, bIsStop:Z
    :goto_1
    const/4 v2, 0x0

    .local v2, i:I
    :goto_2
    iget-object v3, p0, Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;->mMediaCallbacks:Ljava/util/ArrayList;

    invoke-virtual {v3}, Ljava/util/ArrayList;->size()I

    move-result v3

    if-ge v2, v3, :cond_2

    .line 471
    iget-object v3, p0, Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;->mMediaCallbacks:Ljava/util/ArrayList;

    invoke-virtual {v3, v2}, Ljava/util/ArrayList;->get(I)Ljava/lang/Object;

    move-result-object v3

    check-cast v3, Lcom/android/internal/policy/impl/KeyguardUpdateMonitor$MediaStateCallback;

    invoke-interface {v3, v0, v1, p3}, Lcom/android/internal/policy/impl/KeyguardUpdateMonitor$MediaStateCallback;->onMediaUpdated(ZZLandroid/net/Uri;)V

    .line 470
    add-int/lit8 v2, v2, 0x1

    goto :goto_2

    .end local v0           #bIsPlaying:Z
    .end local v1           #bIsStop:Z
    .end local v2           #i:I
    :cond_0
    move v0, v4

    .line 467
    goto :goto_0

    .restart local v0       #bIsPlaying:Z
    :cond_1
    move v1, v4

    .line 468
    goto :goto_1

    .line 473
    .restart local v1       #bIsStop:Z
    .restart local v2       #i:I
    :cond_2
    return-void
.end method

-Now find this line ".method public getFailedAttempts()I"

above it again paste this :

Code:

.method public getChangedTimeZone()Ljava/lang/String;
    .locals 1

    .prologue
    .line 1131
    iget-object v0, p0, Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;->timezone:Ljava/lang/String;

    return-object v0
.end method

this one's last for this file

, search for ".method public isDevicePluggedIn()Z"

and above it paste :

Code:

.method public isDeviceCharged()Z
    .locals 2

    .prologue
    .line 866
    iget v0, p0, Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;->mBatteryLevel:I

    const/16 v1, 0x64

    if-lt v0, v1, :cond_0

    const/4 v0, 0x1

    :goto_0
    return v0

    :cond_0
    const/4 v0, 0x0

    goto :goto_0
.end method

-Now close this file and open "\smali\com\android\internal\policy\impl\LockPatternKeyguardView"

-Search for this method now ".method createLockScreen()Landroid/view/View;"
Find this (Jus one line below)

Code:

    .prologue
    .line 868

below it paste this :

Code:

    const/4 v2, 0x0

    const/4 v0, 0x0

    iget-object v3, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mContext:Landroid/content/Context;

    invoke-virtual {v3}, Landroid/content/Context;->getContentResolver()Landroid/content/ContentResolver;

    move-result-object v3

    const-string v4, "lockscreen_style_pref"

    invoke-static {v3, v4, v2}, Landroid/provider/Settings$System;->getInt(Landroid/content/ContentResolver;Ljava/lang/String;I)I

    move-result v0

    const/4 v2, 0x1

    if-eq v2, v0, :cond_3

    const/4 v2, 0x2

    if-eq v2, v0, :cond_3

    const/4 v2, 0x3

    if-eq v2, v0, :cond_3

    if-eq v2, v0, :cond_1

    :cond_0
    new-instance v0, Lcom/android/internal/policy/impl/LockScreen;

    iget-object v1, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mContext:Landroid/content/Context;

    iget-object v2, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mConfiguration:Landroid/content/res/Configuration;

    iget-object v3, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mLockPatternUtils:Lcom/android/internal/widget/LockPatternUtils;

    iget-object v4, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mUpdateMonitor:Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;

    iget-object v5, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mKeyguardScreenCallback:Lcom/android/internal/policy/impl/KeyguardScreenCallback;

    invoke-direct/range {v0 .. v5}, Lcom/android/internal/policy/impl/LockScreen;-><init>(Landroid/content/Context;Landroid/content/res/Configuration;Lcom/android/internal/widget/LockPatternUtils;Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;Lcom/android/internal/policy/impl/KeyguardScreenCallback;)V

    goto :goto_0

    :cond_1
    new-instance v0, Lcom/android/internal/policy/impl/LockScreen;

    iget-object v1, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mContext:Landroid/content/Context;

    iget-object v2, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mConfiguration:Landroid/content/res/Configuration;

    iget-object v3, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mLockPatternUtils:Lcom/android/internal/widget/LockPatternUtils;

    iget-object v4, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mUpdateMonitor:Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;

    iget-object v5, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mKeyguardScreenCallback:Lcom/android/internal/policy/impl/KeyguardScreenCallback;

    invoke-direct/range {v0 .. v5}, Lcom/android/internal/policy/impl/LockScreen;-><init>(Landroid/content/Context;Landroid/content/res/Configuration;Lcom/android/internal/widget/LockPatternUtils;Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;Lcom/android/internal/policy/impl/KeyguardScreenCallback;)V

    goto :goto_0

    :cond_2

after ':cond_2' there will be your default lockscreen so dont leave any line between them.

After the end of your default lockscreen , it might be like this
" invoke-direct/range {v0 .. v5}, Lcom/android/internal/policy/impl/CircleLockScreen;-><init>(Landroid/content/Context;Landroid/content/res/Configuration;Lcom/android/internal/widget/LockPatternUtils;Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;Lcom/android/internal/policy/impl/KeyguardScreenCallback

V
"
paste this

Code:

    :goto_0

then on the next line after "return-object v0"
paste this

Code:

    :cond_3
    new-instance v0, Lcom/android/internal/policy/impl/CyanogenLockScreen;

    iget-object v1, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mContext:Landroid/content/Context;

    iget-object v2, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mConfiguration:Landroid/content/res/Configuration;

    iget-object v3, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mLockPatternUtils:Lcom/android/internal/widget/LockPatternUtils;

    iget-object v4, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mUpdateMonitor:Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;

    iget-object v5, p0, Lcom/android/internal/policy/impl/LockPatternKeyguardView;->mKeyguardScreenCallback:Lcom/android/internal/policy/impl/KeyguardScreenCallback;

    invoke-direct/range {v0 .. v5}, Lcom/android/internal/policy/impl/CyanogenLockScreen;-><init>(Landroid/content/Context;Landroid/content/res/Configuration;Lcom/android/internal/widget/LockPatternUtils;Lcom/android/internal/policy/impl/KeyguardUpdateMonitor;Lcom/android/internal/policy/impl/KeyguardScreenCallback;)V

    goto :goto_0

Now you may save and close the file.

Now recompile the android.policy.jar and push it to /system/framework with lidroid-res.apk .
Also Push the Lidroid-Parts.apk to '/system/app'

In case If you already have 14 toggles in the status bar adding this may affect it resulting in force closes . So to fix it follow this :

*Prooceed here only if you have 14 status bar toggles mod in your rom*

1.Decompile SystemUI.apk
2.Delete these two folders (if present) : /smali/com/lidroid & /smali/lidroid
3.Download Status_bar_fix from attachments below.
4.Extract it and copy the smali folder to your decompiled SystemUI.apk
5.Recompile and push the SystemUI.apk back to /system/app

putting modded classes.dex and res in original systemUI.apk will not work?

AvijitGhosh82 · Jul 6, 2012

The fix you've added....do we have to use it AFTER the lockscreen adding part? Or is it a separate part?
