Can you confirm that this only comes with nutiteq-3dsdk-build341-232RC and not with earlier versions? |
|
Also, what do you mean by "hardware acceleration isn't available " ? |
|
Previous version of app was shipped with nutiteq-3dsdk-build311-231RC2 and without "mapsforge layer" option. That all, what we can say at this moment. "hardware acceleration isn't available" means |

Tried to reproduce the issue on Nexus 7 (2012 version, Android 4.4.2), but could not. Got lots of messages 'App is not responding', but this is probably not related to the issue here. |
After updating to a new version of sdk (nutiteq-3dsdk-build341-232RC) we get strange errors, like that:
Devices: HTC Sensation XL with Beats - Android 4.4.2,
LG G2 (g2) - Android 4.4.2,
Galaxy S2 Plus (s2ve) - Android 4.4.2,
Nexus 7 (deb) - Android 4.4.2
Seems like it happens when MapView using mapsforge layer as base layer and hardware acceleration isn't available on that device. But this issue may not be related with map sdk.
Unfortunately we don't have listed devices to check issue.
