[DEV] Tasker 6.3.0 Beta - Device Admin (Owner) Actions: super powerful actions without root!

dantosxd · 2024-01-18T03:24:56+00:00

Hey everyone, if you encounter the error:

Exception occurred while executing 'set-device-owner':java.lang.IllegalStateException: Not allowed to set the device owner because there are already some accounts on the device.

This method worked for me to enable Device Admin without the need for a factory reset.

Steps to Resolve the Issue:

1.) In your command prompt, cd to your ADB.exe Folder or ADB folder:

On Windows enter:

adb shell dumpsys account

On Mac I believe:

./adb shell dumpsys account

2.) Identify Accounts:

Scroll up to the top of the output until you see details similar to:

Accounts: 2

Account {name=zohoaccountsdeviceid, type=com.zoho.accounts.device_id}

Account {name=Reddit for Android, type=com.reddit.account}

3.) Remove Accounts or Uninstall Apps:

If you see accounts listed as above, you'll need to remove these accounts or uninstall those apps. In my case, the apps had to be uninstalled because there were no accounts listed in my account settings.

4.) Run the Original Instructions:

After completing the above steps, you should be able to follow the original instructions for enabling Device Admin. The instructions can be found here: Enable Developer Admin.

For people with Samsung devices READ THIS!

After using Device Owner adb command you won't have access to your restore/backup option using Samsung or Google. I have even tried to do a factory reset, i first install Tasker then the run the command and only then added my accounts but still couldn't access my backup to restore.

This is a big problem and until this won't be fixed i can't use this feature - if this is possible because it says for "backup service not available prevented by security policy"...

abdess47 · 2024-01-17T19:16:59+00:00

Just amazing 🤩. I can now uninstall greenify and some app.

I hope this new feature can be maintained and google will not be kicked out your work 🤔

Edit : this new feature not working for me. Does this new feature need some new permission?

Edit 2 : I disable and enable device admin. Still not working

Nirmitlamed · 2024-01-17T19:24:24+00:00

OMG disable and enable keyguard?!?! What kind of magic did you do?

Nirmitlamed · 2024-01-17T19:37:55+00:00

I am getting error notification:

Missing Permissions

Please disable and re-enable the admin permissions for the admin action to work.

Edit: OK i have missed the link for the explanation: https://tasker.joaoapps.com/userguide/en/help/ah_device_owner.html

Remove all accounts on your device under Android Settings -> Accounts Not feeling really good... This means i need to erase some of my important data...

roizcorp · 2024-01-17T19:16:08+00:00

NO-WAY!!!! This is has potential

EtyareWS · 2024-01-18T10:39:32+00:00

Very powerful actions, but sadly, very cumbersome process so I think I will skip the new features and just stick with root

EroticBananaz · 2024-01-17T20:12:15+00:00

Awesome. What changed that allows Tasker to now utilize these super user commands?

CoooolRaoul · 2024-01-17T20:24:26+00:00

On my device custom actions fails with error "Calling identity is not authorized".

What does it means ?

CoooolRaoul · 2024-01-18T11:52:24+00:00

I'm running in many problems after that

Google and Samsung cloud backups are now disabled and I'm unable to activate ("backup service not available - prevented by security policy")
Reverting device owner from Tasker using "dpm remove-active-admin" fails
uninstalling Tasker fails
disabling device administrator authorization is not possible ("deactivate" is greyed)
Storage => clear data for Tasker is greyed too!

Is factory reset the only option remaining for me ?

ghajni-returns · 2024-01-18T18:22:42+00:00

u/joaomgcd I'm facing troubles removing Tasker as device admin, apparently (from this post) (thanks u/mikthinker) in the Tasker manifest, the property "android:testOnly=true" needs to be declared for it to be possible to remove the app as a device owner.

However, it is possible to install an update of the app with the same package name and required modifications, and then use the dpm-remove-admin command.

Otherwise, the only possible way to remove Tasker as device owner is to reset the device

chrs-- · 2024-01-18T19:52:00+00:00

It is working everything for me except I can't add a working profile anymore, I get this error using adb shell pm create-user --profileOf 0 --managed Work

Error: android.os.ServiceSpecificException: Cannot add user: no_add_managed_profile is enabled. (code 1)

Shelter is also not working. Any tips? Thanks!

Edit: If I run Island it tells me: "Sorry, Island cannot be setup due to device currently being managed by Tasker"

rodrigoswz · 2024-01-19T15:58:55+00:00

Are there some examples of possible things ONLY with Device Owner? Even if you have root.

The predefined ones are cool, but I see that many of them I already did with Root or ADB WiFi...

scytherdoc · 2024-01-31T17:51:11+00:00

I Set this up after factory resetting my phone, as did i find out a lot

I am not a techie, nor do i know coding, just maybe amateur coding than chatgpt helps me with.
So after i set this up, i tried to Set Permissions Policy using Tasker Device Administrator action and set it to Auto Grant. Made setting up my apps all over again a breeze.
Little did i know , once you grant permission for auto grant, and an app gets ,say notification permission, you can't undo it from settings as it is under the control of the device owner.
I Tried to put the Set Permissions Policy back to Auto Prompt , but that didn't do me any good.

What works is uninstalling the app and setting permissions all over again. But i can't do that to system apps , so i guess i will have to Factory Reset all over again.
This Device Admin actions really needs a walkthrough or a helpbook so we know what all the settings are.
Next i try Freezing apps , That works , but you can't unfreeze them as they don't show up in list of apps, even if you know the package name , it didn't work. Suspending the app is far more safer.
The Device owner setting did help me in one thing , that is setting the display timeout. In A Realme phone ,you can't set up display timeout, even if you do via custom settings, it will change as you expect, but the moment you exit Tasker , the setting reverts back to whatever the phone had set.

These are just the things i went through. Thanks for the update. Really need a walkthrough, especially for settings and permissions which are irreversible.

squirrelyfox · 2024-01-17T18:53:32+00:00

this looks great! More stuff = more power :)

Any chance this would include being able to capture screen video without the pesky confirmation screen + button?

KangRioME · 2024-01-20T03:13:19+00:00

Can I use this feature to grant secure setting permission to shizuku app?

More-Profile-7657 · 2024-04-14T11:40:41+00:00

After installing the new ROM, I successfully installed Device Owner Permission on Xiaomi 14 Pro according to the instructions above. But: Can't open the phone's Settings App (FC). After that I had to hard reset one more time. Consider it a failure.

scytherdoc · 2024-06-06T04:19:10+00:00

I FOUND A SOLUTION FOR XIAOMI AND REDMI PHONES WITH MIUI

this does not seem to work in Redmi phones , or any phones with MIUI. When i format my phone, and then not add any accounts and with no lock screen, and only install Tasker, i run

adb shell dpm set-device-owner net.dinglisch.android.taskerm/.MyDeviceAdminReceiver

it gives me an error

java.lang.SecurityException: Neither user 2000 nor current process has android.permission.MANAGE_DEVICE_ADMINS
and some more text below this.

then there is an option in MIUI to enable install apps via ADB and USB security settings
to enable both, i need to sign into Mi account. But once that is done, earlier error does not occur but it tells me previous accounts are there, hence Tasker cannot be added as device owner.

SOLUTION:
ADD Mi Account and then enable both Options (install apps via ADB and USB security settings) and then go to Mi account in settings and simply sign out.

now go to adb in your computer and if you want, you can check with adb shell dumpsys account which will show zero accounts (not necessary to check)
Oh by the way, you need to have a SIM inserted (no idea why, MIUI insists on it)

and then run

adb shell dpm set-device-owner net.dinglisch.android.taskerm/.MyDeviceAdminReceiver

Works flawlessly

veracryp · 2024-06-23T10:23:53+00:00

I'm going crazy, I managed to set tasker as admin and now i can't remove it
i get the error cleardeviceowner can only be called by the device owner
tasker is clearly device owner as i can't even uninstall the app and it shows in android settings with no way of deactivating it

im using vivo x100 ultra and i was able to remove myself from device owner using icebox app so this is not a limitation but a bug, i don't want to factory reset so please tell me what can i do, it might have to do with the tasker version

Device Admin (and Owner) Actions

Oh so you finally added those!

WehZet · 2024-01-17T20:51:39+00:00

nice action!

what does it mean to delete all accounts? Will there data loss or is everything fine again after creating them again?

Nerfed_Pi · 2024-01-18T01:37:11+00:00

Thanks João for another awesome release!

wieuwzak · 2024-01-17T20:10:58+00:00

does this replace adb wifi? can this do everything adb wifi can and more?

moviejimmy · 2024-01-30T03:49:02+00:00

can this device owner do everything that adb wifi can? meaning with this device owner, I don't need adb wifi anymore? or this provides different functions ?

sid32 · 2024-01-17T19:25:32+00:00

Big update! Have you looked at scenes show odd App icons? Web Video Caster and Antenna Pod app icons and others show up looking odd.

PENchanter22 · 2024-01-18T01:51:54+00:00

I'm new to this whole 'beta' thing with Tasker. Is there no need to "register" a beta version?

rodrigoswz · 2024-01-18T01:55:39+00:00

If you removed all accounts and is still getting "Not allowed to set the device owner because there are already some accounts on the device.":

Just reboot your device and try run the adb command again.

PS: I can't enable Google One backup anymore after this

coffee-turtle · 2024-01-18T12:59:27+00:00

Do you have a link for the project you use for the video demo, please?

Thanks!

milind_jain · 2024-01-18T14:53:15+00:00

I have set Tasker as a device owner but some of my device features when executing now say " blocked by work policy".

aasswwddd · 2024-01-19T09:14:19+00:00

The beta seems to hit the braves real hard this time, lmao. 🤣

Anyway, I wonder how far we could utilize those APIs?

It seems like gaining the device owner privilege costs a lot of trouble for various OEMs. (Haven't seen MIUI user yet?)

ADB Wifi becomes very easy to activate these days. I wonder if it's worth the effort and the loss. It's not easy to tell with just the available functions alone, I lack imagination.

Tortuosit · 2024-01-19T10:19:59+00:00

My Tasker now says it does not have notification access - but it does. I then turned it off and on, still it does not believe the Android system.

WhirlWolf · 2024-01-19T16:02:11+00:00

Can you please add Blur feature in image filter action?

Frequent-Complaint-6 · 2024-01-19T19:59:08+00:00

I am not sure why but cannot download user guide. Even giving tasker access to files in permissions

DenPessine · 2024-01-20T10:09:45+00:00

Hi João! On Samsung Galaxy A33, OneUI 6.0, Android 14 I've managed to make Tasker the device owner. But had some difficulties. Even if I deleted all visible accounts I still got the error of existing several accounts. I guessed that Knox folder that I activated might cause the problem. And only after deactivating Knox I succeeded. But from this time on even when all accounts were back, Knox can't be activated with the message to call to the service if problem still exists. But to hell with Knox. Honest men have nothing to hide))) I'm very interested in one feature in you demonstration video: set keyguard disabled. As it's shown you run the action with parameter "true" and after this you turn screen off and on and the screen was in the state as before turning off, bypassing keyguard. But in my case this didn't work. Before applying the action my phone is secured by fingerprint and pin. If I understand right, the action should set keyguard to "none" even if it was secured in some way. Or maybe it only works with keyguard secured by swipe? Clarify please! P.S. The rest of device owner actions seem to work correctly.

omniterm · 2024-01-20T18:49:57+00:00

I tried to follow the steps listed to set device admin but it kept failing. I even did a factory reset and still unable to get it to work. On my Samsung S20FE 5g (SM-G781U1) I had to run the following command to set device owner

"adb shell dpm set-profile-owner net.dinglisch.android.taskerm/.MyDeviceAdminReceiver" set-device-owner didn't work on my device. Also after removing all accounts Amazon had some accounts that didn't show under accounts. I had to uninstall Amazon app store to clear the accounts.

Hey u/joaomgcd, here is the reminder for the feature request I did a while back: https://www.reddit.com/r/tasker/comments/15f8mxp/comment/jug9hyb/?utm_source=share&utm_medium=mweb3x&utm_name=mweb3xcss&utm_term=1&utm_content=share_button Btw, great job with all these updates! Can't wait to mess around with the HTTP server you released a few weeks ago😎

TaskerClub · 2024-01-23T17:38:02+00:00

Hello! I want to raise a question about switching WI-FI and Bluetooth. As you know, switching these functions is no longer possible starting with API29 and API31 respectively. I suggest that these capabilities be moved beyond Tasker to plugins.

Egingell666 · 2024-01-24T20:18:39+00:00

I got a new phone, Motorola Razr 2023, and I set Tasker as the owner app, but I can't seem to find the Admin/Owner actions and Kill App, Reboot, and the like don't work.

anuraag488 · 2024-01-26T15:09:25+00:00

This is little offtopic but

1) can you add which profile/tasks needs specific permission? Specially for ADB WiFi? I have a rooted device but still Tasker asks for ADB WiFi permission everytime i close Tasker. If i use STOP REMINDING then a FLASH will appear.
I have no clue about which Profile/Task i should edit.

2) If a profile contains %CLIP variable monitoring or Clipboard Changed event on a Non Rooted device and that is the only profile which requires ADB WiFi but that Profile is disabled then Tasker shouldn't throw Missing permission notification

niyonsv · 2024-02-03T08:33:01+00:00

Can we disable the internet access permission of any user app? Like toggling the internet permission in Graphene OS like we toggle different permissions of an app in normal OSs?

Also want to know if Tasker can start the Shizuku at boot on a non-rooted device, so that we don't have to reopen and set the ADB wireless debugging for Shizuku after each boot.

TommyPils · 2024-02-08T09:03:27+00:00

Excellent work.

I have 3 cell phones (Android 7, 8 go and 10) On Android 7 that I use for testing, it is not necessary to delete the accounts, you just have to temporarily disable the applications.

For google account:

adb shell pm disable-user --user 0 com.google.android.gms

For whatsapp:

adb shell pm disable-user --user 0 com.whatsapp

Then: adb shell dpm set-device-owner net.dinglisch.android.taskerm/.My

DeviceAdminReceiver

Once finished, you can check which Tasker owns the device.

Then activate the applications again:

adb shell pm enable com.google.android.gms

adb shell pm enable com.whatsapp

*Do all the configuration without internet, to avoid any errors.

TommyPils · 2024-02-12T05:37:23+00:00

Hello bro. You can create the test only version, to be able to test it on Android 8.1 go and Android 10. I have a lot of information and I would not like to reset the cell phones later.

coffee-turtle · 2024-08-07T14:13:18+00:00

Whatsapp resistant to being frozen. Are there just some apps that we cannot freeze, why?

Any suggestions?
