Multiple installed ROMs: How to share Apps and Data? - General Questions and Answers

Hi everybody,
recently I installed Dual Boot Patcher and RRemix as 2nd ROM. Now I wonder whether it is possible to use apps and/or aata commonly within both ROMs.
According to this description apps need to be installed within both ROMs. But how could I share my already existing WhatsApp threads or history and maps of my navigation software?
And even more: How can I use calendar entries and written memos commonly within both ROMs - since calendar apps and note apps are different stock apps within each ROM?
Would I have to install an independant calendar and notes app within either ROM?
Thanks in advance for your help!
Bye

Google Calendar and Google Keep are great calendar and notes app with sync functionality. So backing up and transferring data from those two apps on different ROMS should be easy and automatic.
The rest of apps, you'll have to backup and restore with Titanium backup.
But you'll have to backup before changing between ROMs, then restore that backup after booting into the new ROM. or else your Whatsapp conversations/New data in ROM A will get overwritten with the conversations in ROM B instead of being merged.

OK, just tried it using VVS Mobile app. Marked it for sharing within Dual Boot Patcher in MIUI (first ROM). Afterwards I booted into RRemix (2nd ROM), installed it there too, marked it for sharing in addition. After rebooting I could see my saved VVS connections created within MIUI. Similar with here Maps - at least it finds downloaded offline maps but no route history. So it seems to work.
But with WhatsApp I did not get it working. While having it marked within both ROMs to use shared data I cannot see my chats within 2nd ROM. Does anybody have a helpful hint here?
Also contacts, calendar, SMS and call history is not shared while the apps within each ROM are marked for it. I guess I will have to use identical apps within either ROM in order to be able share their data? Or is there sth. else I need to do?

Titanium backup - how to backup all current apps w/ specific system settings?

hi guys,
These days I'm testing quite a few ROMs and as a consequence have my phone screwed up quite frequently.
Now I have a simple requirement - I want to backup all my current apps + app data as well as some specific system settings (like Bluetooth pairings, SMS messages, Gmail accounts, etc.). I dont want to backup all system settings because that is precisely what gets screwed up between ROMs.
Now, I'm not able to figure out how to achieve this. Now, I created a filter, but that pretty much asks me to choose specific apps - it does not let me do things like all user apps + specific system data.
Could someone help ?
Can you do all the backups, and then, filter when restoring? (I`m new to TB)

[Q] Application suggestion needed. Basic but not found!

Hi all,
Making this post with a totally frustrated mind. I am looking for an app which will allow me to select few contacts and export them to csv or any other format which can be imported latter. Tried several apps. Not even single one does the job.! Please suggest an application which does this job.
OR
I am even ready to remove my unwanted crappy contacts. But still can't find an app which allows me to select multiple contacts and remove them together.!
I am wondering years older Android lacks this feature.
I am on Android 5.0+ AOSP ROM. Device is nexus 4 (I know it doesn't matter. Just saying)
Any idea about this ?

Why aren't you using the build-in contact app? You can select several contacts to delete/export them by pressing the menu button and selecting the delete/export button and then selecting contacts.

What are the repercussions of removing contacts provider in Android?

Personally I think the contacts provider (and other providers)in Android is a huge security risk. Every app and it's brother wants full access to your contacts so they can mine them for usable information. This can be just to add easy links to friends or to spam them with advertisements or offers to identity theft.
I've started using a pim manager that does not access Androids contact provider, calendar provider , tasks or other providers in it's operations.(And I really wish it was open source)
I have already removed the Google sync apks from my device and have removed contacts, calendar in the past. But not the providers.
It might cause some badly written apps to crash.
But I can't forsee any other serious problems.
Ideas? Thoughts?
Honestly sounds like a good idea..
Myself I decided to go for a while without any gapps and any other "store" installed on my phone.
My contacts are imported from a .vcf file which i update manually when needed.
I also have installed AFWall+ and i blocked the internet access to pretty much all the other apps including the system ones.. (everything i could get away with basically )
This could be a solution as well but it's rudimentary one at the moment.

I already don't have Google apps on my device.
Everything blocked with afwall+ using profiles so things only get net when I'm using them on the net.
Fdroid is where I get 90% of my software and from the internet for much of the other 10%
I have a old phone with nothing on it personal at all. Which has play store for the 3 or 4 paid apps I need, it does updates for them and a few free ones. I copy the apks over to my daily driver.
I constantly hound developers on play store to support offline devices and not to implement features that break the app when there is no internet. Even app I don't use lol.
(I have 2 tablets and far too many old phones.only two devices are online(some are local lan only))
Someone should start a offline foundation. But being online it might be ridiculous..
I too removed contacts by using /system/app mover from f-droid. It was unintended as I wanted them as a user application but they wouldn't work like this and the icon vanished, that was fine with me for a long time. The other day I wanted contacts for signal (and telegram also won't work without them). I restored the application files from a backup,
For reference in /system/app/ the missing files were
SecContacts.apk
SecContactsProvider.apk
Other contacts programs like Simple Contacts can't run without a system permission called com.android.contacts and without those files in /system/app the permission doesn't get created at boot. The result being that no contact creation is possible.
What I would really like is a modified version of the system app that passes contacts data to the calling program depending on individual contact entry permissions with regard to each calling app; one list for telegram, another for signal etc. I gather that recent android versions above 6.0.0 have functionality to check calling application certificates so something along these lines should be possible. For earlier versions it might be necessary to switch between multiple contacts databases before starting the messaging app and also removing it from the autoboot list.

Possible to get the Pixel sms backup on other phones? (Google Drive app data)

On Pixel phones, there's a new backup and restore option which includes sms.
Even though I have Android 7.1 on my Nexus 5X, I don't have this feature. It seems to be a Pixel exclusive for now. However, it should be possible to replicate it somehow I think. Could this be part of Google Play services - or Google Drive, where we lately saw some new backup options in the hamburger menu and settings menu? I'm not rooted, but I still have my hopes up this piece of functionality could be activated on other phones. Did someone look into this?
As an example, we have a backup solution for call history and blocked numbers. It's been there for a few Android versions. The sms functionality seems to be very similar to those. Can't someone find out if it's done through Drive, Play services or some system component, and then begin experimenting?
Otherwise, if we can't replicate the Pixel functionality, then could something similar be built using the Google Drive app data backup? Sms backup apps typically have a solution of their own, such as file export, Gmail import or creating a folder in Google Drive. But what if my sms messages could be backed up as app data instead (from a homemade app, released to the play store for this purpose), using the Google Drive app data backup tool? Could someone write an app for that? Or are there limitations, perhaps the sms container on the phone can't be reached in that way?
I'm curious about what you have to say about this!
EDIT:
To clarify, I know there are many good backup solutions out there. What I'm asking for, is to have that task done as natively as possible in the OS. That's why I'm curious about the things above! Cheers

Quota and Functionality Questions related to Device Backup

I am confused about inconsistences between Device Backup on two different Pixel phones:
On my old Pixel phone, the Backup app says the backup will use Google One storage, so I do not have it turned on.
On my new Pixel phone, the Backup app doesn't mention Google One. In fact, it explicitly states that the device backup will not count towards "Drive" storage.
I'm not sure the new Pixel phone is fully patched (just took it out of the box) so it's possible the software hasn't been updated to reflect the Google One service.
I have the following questions:
Does the device backup count towards a Google storage quota or not?
Is there a difference between Google One and Google Drive?
On both devices, the device backup states that the information is encrypted before being uploaded, but it is not clear whether the backup is inaccessible by Google (can Google decrypt the backup)?
The device backup states that it will backup: apps, app data, call history, contacts, device settings (including Wifi passwords) and SMS & MMS messages. How do I restore these things on the new phone if I back them up on the old phone first?
Can I selectively restore apps and app data for only a few apps? There are some apps that are device-specific (e.g. Syncthing) where I don't want to necessarily restore the settings and app data associated with that app, because my shared folders will be located in a different place on the new phone. I would rather set up from scratch and establish my new folder locations, then allow the files to sync through Syncthing.
Thanks for any answers you can provide to these questions.
I would also welcome links to resources that explain how this works, especially vis-à-vis the new Google One branding.
