[Verizon Samsung Galaxy S III] Didact74:
I have been away for a while because work is getting crazy, but I managed to throw a little something together for the time being. This is not an original MOD and a lot of the work came from Mirko and TdunHam (Thanks Guys!!) The thread I used to get things going in the right direction was this one:

http://xdaforums.com/showthread.php?t=2128309

So this took a bit to get smoothed out so I could get it to work on the S3 but I managed to get it and now its coming to you!

I think everyone is familiar with this MOD but for those who are not its simple.....if you have an App open, simply hold the back button and it will kill it immediately. Here's the "How-To"!

We will be working with just one file, android.policy.jar. So decompile it and follow on....

Navigate to smali/com/android/internal/policy/impl/PhoneWindowManager.smali

Add the following in RED

.field mAssistKeyLongPressed:Z

[COLOR="red"].field mBackKillTimeout:Z
[/COLOR]
.field mBackLongPress:Ljava/lang/Runnable;

Add the following in RED

.field mLockScreenTimerActive:Z

[COLOR="red"].field mLongPressBackKill:Z
[/COLOR]
.field private mLongPressOnHomeBehavior:I

Find method public interceptKeyBeforeDispatching(Landroid/view/WindowManagerPolicy$WindowState;Landroid/view/KeyEvent;I)J

Since there are so many changes, I have copied the entire edited method to a txt file. Simply copy the entire method from the txt file and replace it in the smali. Diff it out if you want to see exactly what changes I made.

That's all for the edits.

Now find the attached zip and put the kill smali in smali/com/android/internal/policy/impl

recompile and drop in /system/framework

enjoy!

Thanks button!!
