Bought code on the website, struggling to activate it on Android

Trouble with Synthesia, your keyboard, or adapter? Think you found a bug?
When describing problems, always mention your OS and game version (shown at the bottom of the title screen).
  • If your keyboard has USB or MIDI ports, there is a tremendously high chance (>99%) it will work with Synthesia. See what you'll need on the keyboards page.
  • If you have a Logitech webcam and can't get your keyboard/adapter to work, see this post.

Hi,
I bought a code on the main website to use on my PC and Android tablet. Activating it on PC went smoothly but when activating on my Android tablet I get the error:
"Server returned an unknown error. 10004. java.security.cert.CertPathValidatorExcerption: Trust anchor for certification path not found."

This also happened when I tried it on my phone.

Not really sure what I can do about this, any advice?

Thanks

pphi

Game version 10.7.5600

Sorry for the trouble.

At the end of September one of the major security certificate authorities on the Internet had their root certificate expire, so older devices that no longer receive updates are no longer able to connect to many websites (including Synthesia's) without security errors. (Here is a news story covering the event.) This has broken many websites and apps for many older devices.

They tried to include a workaround for most older Android devices, and testing on all of our oldest devices, Synthesia still seems to unlock and work correctly. (Curiously, we've only seen the trouble for ourselves on newer devices running Android 6 and later, which shouldn't even need the workaround!)

In any event, our most recent beta version of Synthesia includes a (real) workaround, essentially brute-forcing the security check regardless of what the OS thinks is valid or not. You can sign up for app testing and get it right away. Or, with any luck, the official Synthesia 10.8 update (including the fix) should be going out in less than a week. (This issue is the primary reason for bumping the 10.8 release forward!)

i dont want, but i need to stop your hope... i just bought the full unlock code, and i have the same problem of crash when trying to unlock the android version with my tablet under android 4.4.4 and Synthesia 10.8.5681

i hate DRM because of that... it's just a way to prepare a programmed obsolecence (voluntary or not) ... why should I throw away my perfectly functional tablet? (as it's a tablet with a double boot with a working windows 10 on it but i prefer to use the android version because win10 is a bit slow)

i will try the beta version to see if the result is better...

These are different problems. The certificate issue doesn't cause a crash. And we worked around it in 10.8 so it's no longer a problem.

When exactly does the crash happen? Is it when you try to enter text into a text box? Does it also happen if you enter something into the search box on the screen with the song list? I just heard from an Android 4.2 user a couple days ago about a crash whenever entering text into any box. If that's the case it's just a "normal" bug and nothing to do with DRM. :)

ha ok... what i do :

click on 'unlock synthesia' button,
then click on the white square where you need to put the code( 'type your unlok key here')
at the moment, it open a new screen with a line where you are supposed to put the code and a 'ok' button.

after 1 seconds, (even before i type anything), this screen crash, and i go back on the previous screen

and yes, it seem that the same case with any box where you need to type something (like the 'search' box in Songs) .

it' seem to be the same problem as your android 4.2 user :(

So far I've tested 10.8.5681 on an:
  • ASUS Transformer Pad TF300T (arm-v7) running Android 4.2.1: text entry worked just fine.
  • Acer Iconia One 8 (x86) running Android 4.4.4: it couldn't even boot! Wouldn't get past the Acer logo during power on. (And this appears to be the 3rd one of my old Android test devices whose batteries have begun to swell.) :grimace:
  • The Android emulator running 4.4.4: text entry worked just fine.
So I haven't been able to reproduce the problem yet. :? Do you happen to know the exact hardware and Android version you're running?

Hmm, my usual policy is to grab the trouble-making tablet from eBay, but there doesn't seem to be a single one listed there anymore, which is unusual for a tablet that is only five years old. Maybe because it doesn't seem to have ever been officially released in the US. Oh well.

Do you know which keyboard app you have set to the default? Is it Chuwi's or a different one? Has it recently received an update? If you switch to Gboard, does the crash still happen?

The curious part about this bug is that nothing changed on the text entry pop-up in 10.8. So I'm starting to suspect outside causes. Especially since it was a full month since it's release before anyone reported the problem. (That said, I do have a tendency to forget things and there are often "interesting" interactions that I wouldn't expect.)

i use thumb keyboard 4, but the problem is the same with the stock android keyboard (AOSP). and no, the problem with this tablet is that the android part was not updated by Chuwi since the launching (btw, i bought it on amazon canada)

edit: i tested on 3 different keyboards and the result is the same .. i installed Google keyboard 5.0.20.121473290 (X86) , but no luck, still the same crash

i undestand that trying to use an old system like android 4.4 is like trying to work on win95 for the dev when win11 is out, but a software like Synthesia is a good use for an old tablet / phone that will end his life running only this application...

edit 2 : just for the fun , i installed synthesia 10.7.5566 and the bug was already there..

i see that someone with a galaxy tab 3 got the same problem ( viewtopic.php?f=6&t=10388 )

Hrm, at least one other report of the same problem has come in, but I'm kind of stuck without being able to reproduce it.

Have you been able to see any output from logcat with a stack trace? That might be able to help.

Ah ha! KK/Altair (from that other thread) was able to track something down: check the developer options on your device and make sure "background activities" are allowed to keep running. I was finally able to reproduce this problem by enabling "Don't keep activities" on my Android 4.2 test device.

If that sort of thing is enabled, can you enter text if you disable it?
