Android Question WebView load crashed no error

[ShawnYang]

Hi Erel,
I got a problem with cannot load fully map via online map link in WebView, just like the picture below:

I have had do anything i can but map still broken but no error
1. I catch the data from map via Fiddler, i found it has a little map of data loaded a few second and then it doesn't work
2. I tested it from the default broswer in the phone that the map worked smoothly. but WebView of B4A cannot work still.
3. It has location permission and others.

Could you please help me to have a look the webview?
Which permission i lost?
What can i do?

Thank you in advance!

This is the original code of HTML which has some problems in WebView, maybe it can give you some idea to solve the issue

OK, i give up and i use the UtimateWebview instead of default WebView in B4Xpage project and it worked much better.
Thanks a lot
