[App][Rooted]KPPD Control[4.4+][Oreo Compatible now!]

[AlaskaLinuxUser]

Sorry my friend, but the msm8953 (which I think is in your phone) is not a compatible chip. I just made the easy to use app, not kcal itself. If kcal itself will not work on your phone, I cannot help you.

Sorry to hear that you are having trouble. Or should work on your phone. So what is happening that doesn't work?

KPPD Control

Any ideas how to get it working on O? Using Omni 8.1 on Xperia Xc, and system crashes when executing script or applying settings.

What chip is in that phone?
Does kppd from savoca work (link in op)?

Same phone I've been using it with on 7.1.1, Xperia Xc, (f5321), 64bit. I tried with kppd app, and also with script. Editing postproc.conf and saving doesn't cause crash,but doesn't make a change. Attempting to run script, or tapping 'Enable' in app causes freeze and crash.

Interesting note - running the command in terminal in recovery causes changes to take effect. Not persistent on reboot though. Maybe a rom issue, not version issue

Interesting. Just an aside, but it will not be persistent after reboot. If the app works properly, then it would re-enable kppd after reboot. But if you run it from the command line, then the app will probably not be able to do that.

Could you pull a logcat? If you turn on adb, hook to you computer, and run adb logcat, then try to use the app. After it freezes or crashes, you could copy the terminal output and post it here. Without a log I can't begin to trouble shoot.

However, you said this is Oreo, correct? Oreo has very stringent security, even if you are in permissive. I suspect that to be the case, as an off the cuff guess. [emoji2]

I don't know much about reading logs, but I see around line 100 a Java permission error in response to kppd. Then everything just dies. I left the phone on for about 5 minutes after freeze, but seems like log stopped about 1 minute after...

Any hope?

01-15 06:51:57.632 *3412 *3412 W System.err: java.io.FileNotFoundException: /storage/emulated/0/documents/kppd.conf (Permission denied)

Here is the actual fail. Yes, you are right about that.

1. Okay, does the folder : /storage/emulated/0/documents/ exist? If not, can you create it? Notice the lower case documents.

2. Does kppd.conf exist in that folder? If not, can you create a blank file of that name there?

3. Does the app have storage permission? (About app, permissions.)

4. Does the app have root permission?

I had uninstalled, so I reinstalled, and made sure all above were 'yes', and tried again. Still freeze and crash, but log is quite different. I see some 'no response' and 'timeout' lines down around line 140, and a few 'error opening trace file'...

Great work!

Notice line 253, this is the tombstone. This is where it dies. The process that dies is 2126. That process starts on line 7, before kppd starts. It is the screen buffer. Odd....

There are quite a few permission avc read/write errors throughout the log, but I'm not entirely sure which ones are related. Oreo is so new, and your xposed modules add notes to the log, making it difficult to pin down.

I'm looking at this on my cell phone, so maybe tomorrow I can look at the logs on a desktop screen, so I can see and search better.

Also Oreo is now available for my lg g4, so perhaps I can try it there, tomorrow as well.

Thanks. I wonder if changing log level or attempting on clean-flashed rom might help...

Wouldn't hurt, but let me try that on my clean Oreo phone tomorrow, to save you the hassle.

Okay, tested on AOSCP Oreo for the lg g4, and it didn't work at all for me. Looks like permission problems, and maybe a location issue for where the files go. So, I'll try to iron this out over the next couple of days.

Okay, reworked and sucessfully tested on an LG G4 H811, running AOSCP 8.1. Works like a charm. I updated the play store to version 1.6, but it may take a couple hours for the play store to update. And the new apk is available here:
https://github.com/alaskalinuxuser/app_kppdcontrol/blob/master/app/kppdcontrol_v1.6.apk

Give that a try and see if it works.

Note, if you have previously installed kppd, you need to go delete the old app. Then, go to the terminal or adb:

$ su
# mount -o rw,remount /system
# rm /system/bin/kppd
# mount -o ro,remount /system

Then I recommend that you reboot, and install the new app.
Give that a try and let me know how that works for you.

Nice - I'm back on N atm, but won't last long. I'll check it out. Maybe you should make a thread in Android developed and hacking. Or post in kppd thread at least. I think lots of people would appreciate it...

Thanks

 

[wokawoka]

in case we need to uninstall the app and the daemon, is it enough to uninstall the app and to remove the kppd folder in /system/bin/?
many thanks

 

[wokawoka]

any help? how to correctly uninstall it?
