[Guide] LockScreen torch mod

[rcheung28]

It's in /system/framework but you will also need android.policy.odex which you will need to deodex to be able to see the smali files.

There is a thread in Samsung Galaxy SII Original Android Development by sicopat here: http://forum.xda-developers.com/showthread.php?t=1208320 which states how to deodex a jar file.

You will also need all of the other jar files from /system/framework to be able to deodex it properly.

If you need a hand or some tips, just ask.

Does that mean I'll have to deodex all of the files in framework in order for this mod to work?

No mate,

You just need to make sure that you have a folder on your computer with smali & baksmali in it as well as all the jar files from your framework folder. You will also need to take your android.policy.odex and put it in the same folder. Then you will need to follow the instructions in sicopat's thread.

Once you complete the command, you should have a new 'out' folder which contains all of the smali files from android.policy.odex

I hope this makes sense? Let me know if you need any other clarification.

If I have to android.policy.odex file in the folder, that means I don't have to deodex the android.policy.jar file?

You can't deodex the android.policy.jar file. There is essentially nothing in it. Look at the size of it. It should be about 1kb? Then look at android.policy.odex and it should be much much larger. An .odex file contains all of the information in it that you need to convert the apk or jar file from odexed to deodexed.

Once you smali the android.policy.odex file and get the 'out' folder, you will then need to make your mods to whatever smali files you need to. Then you will need to baksmali the out folder which will give you a new classes.dex file. If you want to deodex android.policy.jar, then you will need to use a program like 7Zip and place that classes.dex file in android.policy.jar but if you want to keep it odexed then you will need to follow sicopat's thread or use alkhafaf's guide on re-odexing here.

Any other questions, just ask.

So I bring all the smali/baksmali files, .jar/.odex files from framework, into the same folder. Execute android.policy.jar with 1.bat. Get a classout folder, work on the files based on this torch mod tutorial. After I'm done, compile it back using 2.bat. I get a .dex file, then I reodex it following sicopat's tutorial.

Is that the correct procedure?

p.s. Dave I appreciate all this help, you're explanations are very detailed, it's just that I'm still new and still need some guidance.

Edit: I went ahead and tried experimenting with smali/baksmali. In the classout folder, I'm not getting the KeyguardViewMediator$4.smali file.

You can either reodex it using sicopat's tutorial or using alkhafaf's auto odexer script. That should be the way you need to do it. I usually use alkhafaf's auto odexer script after I've deodexed and made my edits to smali files.

Mate it's no problems at all. I have had a lot of help on these forums from some awesome people, so I'm very happy to help anyone I can.

It should be in com/android/internal/policy/impl? Are you sure it's not there??

Yup I've tried redoing the entire process once more and I'm pretty sure it's not there. I'm running 4.0.4 ZSLPN downloaded from the stock rom thread.

Ahhhh I think it might be a different smali file for ICS. I believe that the guide is written about JB 4.1.2 maybe?

There might be a different smali file that you need to edit. Maybe search for that :catchall code that the OP states needs to be modified and go from there? Sorry I'm not very skilled in smali editing, it's like a foreign language to me

It's all good. If all else fails, then I'll just access the torch thru a widget. Thanks so much for your help!

Here's the mod for SweetROM v10 only.

Flash zip file in to recovery. Do not forget to do a nandroid backup just in case or you can just push it manually.

[efaustino84]

still failing to get it working after making that fix to my mistake
not sure what I might of missed

 

[jim256]

I've been looking EVERYWHERE for this great feature...Does anyone know if this would work on the Galaxy Note II (AT&T)?

Thank you!

@majdinj

Hi! Is there a way to make this same as MIUI where when you hold and long press the button to activate the torch and after maybe 2 or 3 sec it will lock on Torch On without the need to long press the home button anymore (this will also make the screen, screen off), To turn it off you just have to press the home button again.

Many Thanks!
