Android 4.4 client problem (nothing displayed)

[Gnome]

I have a problem getting the android python client to work properly. The client worked fine on my old phone, but after a water accident I have upgraded to one with android 4.4

Firstly the database files needed to be on the internal storage and not on the SD card because of permission changes in the os.
Now everything is working without any error messages, and it syncs. But when the review page opens, all I get is an entirely blank page. There is even no html when I view the source. I have tried changing the card set to make sure that a standard front to back card is active with no Javascript in it.

Hi,

It seems like your database is empty or not in the correct location.

Does the initial sync take enough time not to be bogus? If you uses a
file explorer, are the files where you expect them to be and have
reasonable sizes? Have you tried with a different browser?

BTW, I have two Android 4.4 devices without removable storage, and the
path to use still is /sdcard. If you're putting them on true core
internal memory, you might have enough space, so also try with dummy
database with a few cards.

Good luck!

Peter

I should mention that I copied the database and the files from my old phone sdcard.

After the first sync the number of cards on review on the PC decreased, so I assume it synched correctly. Also the default.db is the same size (12 169 216 bytes).

 

Have you tried with a different browser?

I get the same result in firefox.

The database is on the internal storage. I tried to store it on an plugged in sdcard at first, but I would get an permission denied error during launch. After looking around on google, apparently there is a change in the android OS 4.4, so that apps on the local storage cannot write to the SD card. So all users trying to install the mnemosyne python client on android 4.4 and later will have to have the database on the internal storage.

See http://beranger.org/2014/01/30/how-kitkat-4-4-killed-android-and-google-keeps-screwing-things/

 

so also try with dummy  
database with a few cards.

I will try to remove the entire database then do a new sync. If that doesn't work, I will try with a smaller database.

 

Good luck!

I tested deleting and resyncing the database again, same outcome.

I then created a new database file in mnemosyne PC and added some cards. I deleted the Mnemosyne database directory on android and started to synch.

However, after the sync was finished, Mnemosyne PC had swiched back to default.db and that database was synched, and the same outcome.

Hi,

Since I cannot reproduce this (as I said, none of my 4.4 devices (Nexus 7, Moto G) have issues with permissions), could you please replace web_server.py in Mnemosyne/web_server with the attached version?

It will print out extra output, like name and path of the database loaded, the webrequests coming in, and the html that will be served. You will need to move back to the python console after launching requests from your webbrowser in order to see this debug info, though.

Good luck!

Since the database is no longer on the external SD card the permissions should no longer be an issue.

Here is the output

Seems I messed up some versions.

Try this:

That one works, however I no longer see the exit button?

It appeared again after a resync for some reason.

Thanks!

[Gnome]

This morning it disappeared again.

[Peter Bienstman]

Strange, I've never seen anything like this, so it will difficult to
track this down.

Let me know if you detect a pattern...

Now the exit button is gone again, and it's been that way for a couple of days.

Is there an alternative way to sync? Perhaps copying the database to the PC?
