RattlesnakeOS problems

[tectiv3]

Prerequisites

• [x] Are you running the latest version?

Description

I have a few problems with this ROM.

1. Defunct search bar on home screen. It doesn't work and couldn't be removed.
2. Alarms don't fire, unless phone is unlocked and even then clock is stopped displayed after alarm goes on.
3. Very poor camera quality. Not a bug per se, but camera nx doesn't work on this ROM for some reason (just crashing).

That's it so far. Do you also have those issues or they are specific to sailfish?

1. Can be added back by included QuickSearchbar back , but it also leaves an user facing app around that I didn't want. I'm open to adding back, just didn't want to see the extra app laying around. I use a different launcher, so I don't have the defunct search bar.
2. I also have this problem with the alarm clock, I captured a stack trace for it with logcat but I haven't been able to find a resolution to it yet. As a workaround, I'm currently using an alarm app installed through Yalp store called 'Alarm' (com.dehox.alarm) - that has been working fine. Definitely want to track this one down though.
3. I don't think stock AOSP has any of the support for fancy camera features that Google provides. You can take a look at: https://copperhead.co/android/docs/usage_guide#advanced-camera-features for what was recommended with CopperheadOS.

1. Well I just want this search bar removed, what launcher do you use?
2. Thank you.
3. Well, it does have camera2 api, I am using open camera, but it's weird.

1. I use Lawnchair installed from F-Droid
2. I don't use my camera a ton but it definitely wasn't great on CopperheadOS either. Do you know if it was working properly for you on CopperheadOS?

[tectiv3]

CopperheadOS died next day I ordered my pixel :) so I never had a chance to use it.

[dan-v]

Ha, better than setting everything up on CopperheadOS and having to re-install I guess :)

[dan-v]

I think i tracked down the alarm clock issue (https://github.com/AndroidHardeningArchive/platform_packages_apps_DeskClock/commit/d745babfba6ece923db55dbef14f8c32b2f86d0e). It appears to be an upstream issue that still isn't fixed. I have a fix on dev branch that I'm testing and will push to master if it fixes the alarm clock issue.

[tectiv3]

Any luck?

[dan-v]

Alright - fix for alarm clock is working for me and merged: https://github.com/dan-v/rattlesnakeos-stack/releases/tag/v0.0.10

• For item 1, I think I'd prefer to have a defuct bar there rather than making changes to Launcher3 as as that's one more thing to maintain. You can see CopperheadOS changes removing it here: https://github.com/AndroidHardeningArchive/platform_packages_apps_Launcher3/commits/oreo-m2-s3-release
• For item 3, I played around with the camera a bit and it appears to be the same as on CopperheadOS, so not sure what I can fix there at the moment.

[tectiv3]

Thank you, I will go ahead and build it!

1. yeah, I switched to lawncher, so it's no longer a problem.
2. is there any way to know why an app crashes on launch?

[dan-v]

cool! having a working alarm clock is nice 👍if you want to try to debug why an app is crashing you can:

• on computer, install adb
• on phone, enable developer options and usb debugging
• on computer run 'adb logcat' and then launch the app that is having issues to see stack trace

[tectiv3]

Thanks! I had to use force. It will rebuild everything and create an ota file?

[dan-v]

Ah yes, I was going to mention that. That setting will just force a new build even though all of the versions are the same as last build. It won't force chromium rebuild though - as that's pretty expensive. After you kick off a build, you might want to run rattlesnakeos-stack without the --force flag just so you don't run any builds you don't need to.

[tectiv3]

ok, camera crashes with java.lang.SecurityException: Failed to find provider com.google.android.gsf.gservices for user 0; expected to find a valid ContentProvider for this authority I suppose it requires GP services for some reason? Ads may be... microG is out of the question since they require signature spoofing and it's just crazy.

[dan-v]

are you trying to run Google camera? it doesn't work without google services..

[tectiv3]

yeah:) That's the only decent camera out there.

[dan-v]

alright - heading to bed. good luck! i expect wireguard and google camera working when i wake up ;)

[cryptocub3]

can confirm alarm is working.

some features I would personally like:

• custom boot animation
• scrambled unlock pin numbers ( like CHOS used to have )
• wireguard I can see is work in progress ( really nice )
• dnscrypt ( or at least force custom dns servers )
• a tool like https://f-droid.org/en/packages/streetwalrus.usbmountr/ would be nice to integrate then we could use the phone to boot custom OS ( don't think achievable without su presence )

thank you for your work.

[dan-v]

Hey @cryptocub3 ! I'm glad to hear you got it up and running! I'm trying to keep the number of modifications to AOSP to a minimum so that there is less maintenance work involved. I'm hoping some of the additional security/privacy features in Android P will fill the void here when it is released. My thoughts on your bullet points:

• I think a custom boot animation would be nice
• Not likely to add scrambling pin unlock as I don't want to maintain this
• tectiv3 is working on wireguard kernel support - if he can get it working it will be an optional feature that you have to enable with flag. the other option that works now is using userland version of wireguard.
• Not likely to add dnscrypt or force custom DNS servers. I don't think CopperheadOS did this either and basically only updated the fallback DNS servers which are only used if you aren't provided a DNS server from DHCP. If you have the latest version of Chromium built you can enable DNS over TLS at least for your browser right now (https://github.com/bromite/bromite/wiki/Enabling-DNS-over-HTTPS). Android P will have system level support for DNS over TLS, but not sure if setting this up will override DNS servers when on mobile network (hopefully).
• USB Mountr looks neat, but not something I want to bake into the OS.

[tectiv3]

Using wireguard as a kernel module isn't possible without su for some reason. Userland implementation works good though, using it in always on mode plus kill switch. But it is the major battery drainer according to stats.

Alright gonna close this one out.
