Failed to async download a tile, running on Android 7 and 8 #142

Closed scharlton closed 3 months ago

scharlton commented 6 months ago

Hi,

I have followed the instructions to run this app on our devices. On Android 10 and above everything is fine. But on the devices we have tested that have Android 7 and 8 all encounter the issue of a blank map.

I have tried with other samples such as hello_mapapp and still encounter the same problem. I tried to change the rendering mode to texture with no luck but looking at the logs (a sample below)_ its failing to download the tiles. Which led me to think credentials was the problem but as its working on newer devices I'm not sure its a credential issue.

Tried to test on WIFI and cellular. The devices all seem to meet the minimum specification required.

Versions used: Flutter 3.16.3 Dart SDK version: 3.2.3 gradle:7.4.2

Device Spec:

Capture_22022024_3 Capture_22022024_2 Capture_22022024_4

Hi, we will look into this issue and get back to you. Just to be sure. Which app version do you use and which HERE SDK?

scharlton commented 6 months ago

Thankyou, I'm using HERE SDK for Flutter version 4.17.0 and app version 1.8.0.

I can see that 1.9.0 was released yesterday and can give that a try too.

stefan-troyke commented 6 months ago

I checked 1.9.0 already and the issue remains... We are working on it...

stefan-troyke commented 4 months ago

Latest update is that this seems to be a pure Flutter issue. Rolling back to Flutter version 3.13.9 or upgrade to Flutter version 3.22.0 fixes the issue. We will release the app version 1.10.0 with Flutter version 3.22.0

The issue has been fixed on master and verified with Android 6. A official release will follow soon.
