Android 8.1 OpenCPN app will not open

[MrAugs]

When I try to open the OpenCPN app on my Lenovo pad powered by Android 8.1.0 I have a unresponsive white screen for a while and then it says "OpenCPN has stopped". After a reopen as suggested it then says "OpenCPN keeps stopping" and finally "OpenCPN is not responding".

I have the latest version of OpenCPN, 5.10.2. I have uninstalled and re-installed but it still won't open. How do I fix this?

I have a similar cheap device not working on O 5.10.2 but on earlier versions.
The RAM memory is only 1 GB and it seems at least 2 GB is needed for 5.10.2.
Could it be the same for you?

My Lenova has 2 GB. So it must be something else...
