after reading many ICS+ users requests, they want 4.2 lock screen clock.. here it is :eek:

Screenshot_2013-07-31-21-23-02.png


Things Needed:
* smali & baksmali
* Text Editor
* Your device framework.jar

Step 1 : in lockscreen digital clock, there are actually 2 clock views overlapping one another...
java source :
Code: 
CharSequence newTime = DateFormat.format(mFormat, mCalendar);
        mTimeDisplayBackground.setText(newTime);
        mTimeDisplayForeground.setText(newTime);
        mAmPm.setIsMorning(mCalendar.get(Calendar.AM_PM) == 0);
and
Code: 
 private static final String SYSTEM_FONT_TIME_BACKGROUND = SYSTEM + "AndroidClock.ttf";
    private static final String SYSTEM_FONT_TIME_FOREGROUND = SYSTEM + "AndroidClock_Highlight.ttf";

so we just have to use both views to get what we wanted, to do so follow steps,
decompile framework.jar goto : com\android\internal\widget\ , open DigitalClock.smali with a text editor..
search for :
Code: 
Landroid/widget/TextView;->setText(Ljava/lang/CharSequence;)V

you will see these lines :
Code: 
iget-object v2, p0, Lcom/android/internal/widget/DigitalClock;->mTimeDisplayBackground:Landroid/widget/TextView;

    invoke-virtual {v2, v1}, Landroid/widget/TextView;->setText(Ljava/lang/CharSequence;)V

    iget-object v2, p0, Lcom/android/internal/widget/DigitalClock;->mTimeDisplayForeground:Landroid/widget/TextView;

    invoke-virtual {v2, v1}, Landroid/widget/TextView;->setText(Ljava/lang/CharSequence;)V

Step 2: below this,
Code: 
iget-object v2, p0, Lcom/android/internal/widget/DigitalClock;->mTimeDisplayBackground:Landroid/widget/TextView;

    invoke-virtual {v2, v1}, Landroid/widget/TextView;->setText(Ljava/lang/CharSequence;)V
add these lines :
Code: 
new-instance v2, Ljava/text/SimpleDateFormat;

    const-string v3, "h"

    sget-object v4, Ljava/util/Locale;->ENGLISH:Ljava/util/Locale;

    invoke-direct {v2, v3, v4}, Ljava/text/SimpleDateFormat;-><init>(Ljava/lang/String;Ljava/util/Locale;)V

    iget-object v3, p0, Lcom/android/internal/widget/DigitalClock;->mCalendar:Ljava/util/Calendar;

    invoke-virtual {v3}, Ljava/util/Calendar;->getTime()Ljava/util/Date;

    move-result-object v3

    invoke-virtual {v2, v3}, Ljava/text/SimpleDateFormat;->format(Ljava/util/Date;)Ljava/lang/String;

    move-result-object v1

so now we just used second clock view which is add to android at API level 11 (Honeycomb).. but not used after ICS... :p

Step 3 : last step, by default as i said second clock view visibility is turned off
java source :
Code: 
         mTimeDisplayBackground = (TextView) findViewById(R.id.timeDisplayBackground);
        mTimeDisplayBackground.setTypeface(sBackgroundFont);
        mTimeDisplayBackground.setVisibility(View.[COLOR="Red"]INVISIBLE[/COLOR]);

to do so delete this line :
Code: 
    invoke-virtual {v0, v1}, Landroid/widget/TextView;->setVisibility(I)V

Step 4 : download font in attachments push them to system\fonts\

Step 5 : Save all changes and compile flash/push/do whateva :p


for those who want to know what is happening study modified AOSP DigitalClock source in attachment (unmodified),

bro you surly missed here :
Code: 
new-instance v2, Ljava/text/SimpleDateFormat;

    const-string v3, [COLOR="Red"]"h"[/COLOR]

    sget-object v4, Ljava/util/Locale;->ENGLISH:Ljava/util/Locale;

    invoke-direct {v2, v3, v4}, Ljava/text/SimpleDateFormat;-><init>(Ljava/lang/String;Ljava/util/Locale;)V

    iget-object v3, p0, Lcom/android/internal/widget/DigitalClock;->mCalendar:Ljava/util/Calendar;

    invoke-virtual {v3}, Ljava/util/Calendar;->getTime()Ljava/util/Date;

change red code in your keygaurd_screen _tab_unlock.xml
Code: 
    <com.android.internal.widget.DigitalClock [COLOR="Red"]android:layout_gravity="left"[/COLOR] android:id="@id/time" android:layout_marginTop="@dimen/keyguard_lockscreen_status_line_clockfont_top_margin" [COLOR="Blue"]android:layout_marginRight="@dimen/keyguard_lockscreen_status_line_font_right_margin"[/COLOR] android:layout_marginBottom="12.0dip">
        <TextView android:textAppearance="?textAppearanceMedium" android:textSize="@dimen/keyguard_lockscreen_clock_font_size" android:textColor="@color/lockscreen_clock_background" android:ellipsize="none" android:id="@id/timeDisplayBackground" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="6.0dip" android:singleLine="true" />
        <TextView android:textAppearance="?textAppearanceMedium" android:textSize="@dimen/keyguard_lockscreen_clock_font_size" android:textColor="@color/lockscreen_clock_foreground" android:ellipsize="none" android:id="@id/timeDisplayForeground" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="6.0dip" android:singleLine="true" android:layout_alignLeft="@id/timeDisplayBackground" android:layout_alignTop="@id/timeDisplayBackground" />
        <TextView android:textSize="14.0sp" android:textColor="@color/lockscreen_clock_foreground" android:ellipsize="none" android:id="@id/am_pm" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="8.0dip" android:layout_marginTop="18.0dip" android:singleLine="true" android:layout_toRightOf="@id/timeDisplayForeground" android:layout_alignBottom="@id/timeDisplayForeground" />
    </com.android.internal.widget.DigitalClock>

if it looks odd, then tune blue code....

    after reading many ICS+ users requests, they want 4.2 lock screen clock.. here it is :eek:

    Screenshot_2013-07-31-21-23-02.png


    Things Needed:
    * smali & baksmali
    * Text Editor
    * Your device framework.jar

    Step 1 : in lockscreen digital clock, there are actually 2 clock views overlapping one another...
    java source :
    Code: 
    CharSequence newTime = DateFormat.format(mFormat, mCalendar);
        mTimeDisplayBackground.setText(newTime);
        mTimeDisplayForeground.setText(newTime);
        mAmPm.setIsMorning(mCalendar.get(Calendar.AM_PM) == 0);
    and
    Code: 
     private static final String SYSTEM_FONT_TIME_BACKGROUND = SYSTEM + "AndroidClock.ttf";
    private static final String SYSTEM_FONT_TIME_FOREGROUND = SYSTEM + "AndroidClock_Highlight.ttf";

    so we just have to use both views to get what we wanted, to do so follow steps,
    decompile framework.jar goto : com\android\internal\widget\ , open DigitalClock.smali with a text editor..
    search for :
    Code: 
    Landroid/widget/TextView;->setText(Ljava/lang/CharSequence;)V

    you will see these lines :
    Code: 
    iget-object v2, p0, Lcom/android/internal/widget/DigitalClock;->mTimeDisplayBackground:Landroid/widget/TextView;

    invoke-virtual {v2, v1}, Landroid/widget/TextView;->setText(Ljava/lang/CharSequence;)V

    iget-object v2, p0, Lcom/android/internal/widget/DigitalClock;->mTimeDisplayForeground:Landroid/widget/TextView;

    invoke-virtual {v2, v1}, Landroid/widget/TextView;->setText(Ljava/lang/CharSequence;)V

    Step 2: below this,
    Code: 
    iget-object v2, p0, Lcom/android/internal/widget/DigitalClock;->mTimeDisplayBackground:Landroid/widget/TextView;

    invoke-virtual {v2, v1}, Landroid/widget/TextView;->setText(Ljava/lang/CharSequence;)V
    add these lines :
    Code: 
    new-instance v2, Ljava/text/SimpleDateFormat;

    const-string v3, "h"

    sget-object v4, Ljava/util/Locale;->ENGLISH:Ljava/util/Locale;

    invoke-direct {v2, v3, v4}, Ljava/text/SimpleDateFormat;-><init>(Ljava/lang/String;Ljava/util/Locale;)V

    iget-object v3, p0, Lcom/android/internal/widget/DigitalClock;->mCalendar:Ljava/util/Calendar;

    invoke-virtual {v3}, Ljava/util/Calendar;->getTime()Ljava/util/Date;

    move-result-object v3

    invoke-virtual {v2, v3}, Ljava/text/SimpleDateFormat;->format(Ljava/util/Date;)Ljava/lang/String;

    move-result-object v1

    so now we just used second clock view which is add to android at API level 11 (Honeycomb).. but not used after ICS... :p

    Step 3 : last step, by default as i said second clock view visibility is turned off
    java source :
    Code: 
             mTimeDisplayBackground = (TextView) findViewById(R.id.timeDisplayBackground);
        mTimeDisplayBackground.setTypeface(sBackgroundFont);
        mTimeDisplayBackground.setVisibility(View.[COLOR="Red"]INVISIBLE[/COLOR]);

    to do so delete this line :
    Code: 
        invoke-virtual {v0, v1}, Landroid/widget/TextView;->setVisibility(I)V
