Export doesn't work.

[nicheosala]

Info

• Version: 1.2
• Source: F-Droid
• Vault encrypted: No
• Device: OnePlus 5T
• Android version and ROM: OxygenOS 10.0.0, Android 10

Steps to reproduce

1. Open Aegis settings
2. Click on "Export"
3. Click "Ok"
4. Sometimes, the app simply does nothing and go back to the main page. Some other times, the following message appears: "Aegis keeps stopping" and then you can choose to view app info or close the app.

What do you expect to happen?

I expected the possibility to store my Aegis backup somewhere.

What happens instead?

The app does not create a backup: it does nothing.

Thanks for your report. Could you obtain a log of the crash with ADB (https://github.com/beemdevelopment/Aegis/blob/master/CONTRIBUTING.md#bug-reports) and share it here? As you're using F-Droid, we do not see your crash in the Google Play Console.

Can you try this patch built into the following debug APK: https://alexbakker.me/u/t4wvxsghkk.apk?

[nicheosala]

I've installed the debug APK and I've repeated the procedure that leads to the error. The problem persists. The behaviour is the same as in the "official" APK.

[alexbakker]

Thanks for reporting back. That's very surprising. For some reason the system app that supports the android.intent.action.CREATE_DOCUMENT intent, required for the Storage Access Framework, can not be found. Did you make any customizations to the stock OxygenOS ROM that could be relevant?

[nicheosala]

Actually, I removed some apps in order to debloat my phone, following a guide like this: https://forum.xda-developers.com/oneplus-7-pro/how-to/debloat-root-via-adb-t3946625 Is it possible that the error is linked to this action?

[alexbakker]

Can you check whether com.android.documentsui is still installed on your phone?

[nicheosala]

It seems it isn't. I connected the phone to the computer, opened a shell and:

adb devices
adb shell
pm list package | grep com.android.documentsui

It returns nothing. I tried to re-install it through pm install --user 0 com.android.documentsui but it returns an error: "Can't open file: com.android.documentsui"

[alexbakker]

That may explain it, as com.android.documentsui is the app that handles the android.intent.action.CREATE_DOCUMENT intent on most devices: https://source.android.com/devices/architecture/modular-system/documentsui. The package name may also be com.google.android.documentsui. It's also possible that OxygenOS ships with its own system file manager with a different package name. Either way, the DocumentsUi component appears to be missing and you need to figure out how to reinstall it. Lots of other apps also rely on it being present.

[nicheosala]

@alexbakker, thank you for your patience. I'll try to figure out how to reinstall documentsui.

A tip: instead of crashing, Aegis could allow the user to copy the contents of the json file to the clipboard. This approach is adopted, for example, by Samourai Wallet.

[alexbakker]

Sure thing. I don't want to be too dismissive, but this seems like something that's out of our hands. Please do let us know if you do manage to fix this. It may be useful if other users ever have this issue.

We can certainly show an error instead of crashing the app, but I would be hesitant to copy the entire vault to the clipboard. Any app would have the ability to read it.

On a side note, we received a report that sounds similar to yours on /r/2fa 2 days ago. Was that you? It'd be good to know whether more users are experiencing this.

[nicheosala]

About the report: no, it wasn't me. For sure, I'll write the solution here, if I'll find it.

[nicheosala]

Solution.

In order to reinstall a system app removed through pm uninstall --user 0 <package_name>, you can use:

adb shell
cmd package install-existing <package_name>

When com.android.documentsui is re-installed, Aegis export works well.

It would be good if Aegis export could also work with other file managers, such as Simple File Manager.

[alexbakker]

Thanks for reporting back. Glad to hear export is now working for you!

It would be good if Aegis export could also work with other file managers, such as Simple File Manager.

As far as I know, there can only be one DocumentsUi module, and it must be provided by the system.
