hi everyone,  
my fuse version is 1.5 on Win 10  
the mapView crashes in the debug build although it is very simple.  
 ![file](https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/gu2SrlKOEDfe-image-1515632103164.png)

with unoproj:

the preview is working fine, but once i build it with: fuse build -t=android and install it, it crashed immediately after trying to open it.  
my test device is samsung J7.

What Android version is your device running? Is there any information thrown as to what causes the crash when you try to run the build using `fuse build -tandroid -r`?

regarding this issue, it turns out that the crash happened because i didn’t add the API Key in the .unoproj. it worked after i have added it.
