[Closed][MOD] NFC on lockscreen and screenoff - requests - Android Q&A, Help & Troubleshooting

Because of missing time to create new mods or updates and the fact that the mods are not compatible to androids new standard runtime ART I have to stop the development of my mods.
Here are some instructions to do it by yourself. It differs from device to device and rom to rom, so you have to try a bit:
Take the Nfc.apk
Search for a function checkScreenState in one of the NfcServicexxx
Replace the states 0x1 (screen off) or 0x2 (lockscreen) by 0x3 (unlocked)
Or just make a diff of my mod with the standard apk.
-------------------
This thread is for everybody who is searching for a mod to enable NFC on screenoff and/or lockscreen.
I can't go through all the boards of all android devices to find your requests.
So if you are searching for such a mod for your device post it here, but search through the development board of your device with the search phrase "nfc" to find existing mods.
Please post your device, the name and a link (xda only!) of your actual ROM (deodexed only)!

Hi, I've searched and haven't found a mod for GS3 (I9300) running Android 4.1.2, stock ROM.
Thanks in advance!

Sorry! I should post a link to full rom, or just the nfc.* files?

Tried to post the link, but I'm a new user and can't post links, so here's a TXT file with the URL.
Thanks!

It's from another forum (androidz.com.br/forum/topic/18952-oficial-roms-41x-oficiais-samsung-galaxy-siii-gt-i9300/). It should be the stock ROM for i9300. I used this ROM to restore my nfc.apk and nfc.odex files.
Thanks

OK. I simply used ARHD 29 because ARHD is always very close to stock.
Try this with the instructions of one of my threads (signature):
http://hox.stephanschenk.de/NfcMod-SGS3-ARHD-lockscreen-screenoff-v1.0.apk

Hi, I tried the apk, but it worked as the stock, only reads the tags with screen on and unlocked.
Also, I deleted both files (apk and odex) but installed only the apk. Is that OK?
Thanks!

Sorry again, but I need a deodexed one (just updated OP). This is the only one I've found http://forum.xda-developers.com/showthread.php?t=2515007
Is it the same os version as yours?
Sometimes some of the sonys seem to be compatible with each other and man can get a rom from another Xperia board.

No. For all I know ART doesn't work with deodexed ROMs and so probably not with deodexed apk. I even can't extract the Nfc.apk from your ROM.
If you find a deodexed ROM with your version I would mod it and you could give it a try.

hi!
thanks for the answer. sad news about ART that was the first thing I did, after first boot [ok, and after rooting] my nex.. I've read that it gives better battery life and better memory/cpu handling, but I'm not a dev, so all I read is all I know
anyway - I've just found both - odexed and deodexed roms here, on xda, the link is: http://forum.xda-developers.com/showpost.php?p=48322288&postcount=1
excuse my stupid question [like I said, I'm not a dev] - but after modifying the apk, is it possible to "odex" it again?

Ok, try this http://hox.stephanschenk.de/NfcMod-Nexus5-Stock-lockscreen-screenoff-v0.1.apk
Use the instructions of one of my threads in signature but don't rename it to Nfc.apk but NfcNci.apk
P.S.: re-odexing seems possible but only with phone: http://forum.xda-developers.com/showthread.php?t=1208320

whoa! that was quick! thanks, I'll try in a sec - just one question to be sure: do I need to delete original Nfc.apk if I'm pushing your app with another name?
