Hi,
we got a problem only concerning 64bit-Clients. We are using premium licence, right now we got about 50 licences for 50 different apps, so this is rather urgent.

Found the issue, while using 3.1. and 3.3.1 version of the library. i upgraded to 3.4. today and the issue still exists.

If we zoom in pdf (doubletap-zoom in, or pinch-zoom) and try to move on the zoomed-in-pdf, the pdf keeps jumping to the first(?) coordinates. This only happens on 64bit. Everything works fine on 32bit clients and the emulator.

i made you a short video, where you can see the issue. in the video you see, that i am doubleclicking and afterwards i try to move the pdf...

as i said, this is rather urgent, as our clients start to adress this issue.

What device are you testing on?
Android version? 5.x I guess.
Are you able to reproduce that behavior using our demo application too?
Zoom/pan/fling are handled on the java side so the CPU architecture shouldn't affect it.

Provide us the requested information, we will do deep check on our side.

i am testing with the android emulator on Android 5.1.

i add you a screenshot with my avd-config:
bit.ly/1ziFzmZ

to get this error on the emulator, you have to activate multitouch-support. start the emulator like this:
emulator -avd N5_64bit -screen multi-touch -wipe-data -scale 0.4

yes, i am able to reproduce the issue with your demo-app (current 3.4). you can find a video here:

once again, with 32bit-emulator your app works fine too.

May you provide you AVD configuration file, please?
I should better understand if you're working on x86_64 or what else.
Actually no official Lollipop API22 is supporting ARM8 64bit architecture.
Are you using Atom x86_64 image?


Added just now: I've seen your actual screenshot. Ok, you're running with Atom architecture.
Is your development workstation Intel or AMD based?

We will check it on a real device and will be back to you soon.
