[Android Themes] Vipul Verma:
Ok guys here I will tell you how to remove am/pm from statusbar. I decided to re write the whole method to get rid of unwanted code and make it more efficient. You can still use both 12hr and 24hr.​

Things Needed:

Notepad ++

Tools

7zip​

How to:

1. Unzip Tools folder to Desktop

2. Place Deodexed SystemUI.apk into folder

3. Hold shift key and Right click in folder. Then click `open command window here`

4. Type apktool d SystemUI.apk and hit enter. This will make a new folder called SystemUI

5. Go to SystemUI/smali/com/android/systemui/statusbar/policy/Clock.smali and open with Notepad++

6. Scroll down to the end of the file and near the end you will see:​

[CENTER].method final updateClock()V[/CENTER]

[CENTER](CODE)[/CENTER]

[CENTER].end method[/CENTER]

Replace whole thing with:​

[LEFT].method final updateClock()V[/LEFT]

[LEFT] .locals 7[/LEFT]

[LEFT] invoke-virtual {p0}, Lcom/android/systemui/statusbar/policy/Clock;->getContext()Landroid/content/Context;[/LEFT]

[LEFT] .end local v1 #dte:Ljava/lang/String;[/LEFT]

[LEFT] :cond_0[/LEFT]

[LEFT] new-instance v3, Ljava/text/SimpleDateFormat;[/LEFT]

[LEFT] .end local v3 #sdf:Ljava/text/SimpleDateFormat;[/LEFT]

[LEFT] const-string v5, "HH:mm"[/LEFT]

[LEFT] invoke-direct {v3, v5}, Ljava/text/SimpleDateFormat;-><init>(Ljava/lang/String;)V[/LEFT]

[LEFT] .restart local v3 #sdf:Ljava/text/SimpleDateFormat;[/LEFT]

[LEFT] goto :goto_0[/LEFT]

[LEFT].end method[/LEFT]

7. Save both files and close Notepad++

8. Hold shift key and right click folder again.

9. Type apktool b SystemUI nSystemUI.apk this will make a file called nSystemUI.apk

10. Open both files with 7zip and copy META-INF and AndroidManifest.xml form original apk to new apk

11. Flash, Enjoy and hit the thanks button.​

Sorry for messy code. It changes the formatting when i post on here. Its good practice to keep code tidy:)​

The attached apk is finished and is based on XXELL5. It has the theming show in screenshot.​
