I am using fuse version 1.5 on Win 10  
I tries to build my app and the following was displayed:  
Building Android app

If the application crashes, we need to see the logs from the crash (and not from the build).

Try running `fuse build -tandroid -r` in CMD and see if you get anything useful there. If not, you might need to debug the crash using Android Studio. `fuse build -tandroid -d` opens the compiled project in Android Studio, where you can Run -\> Debug.

i tried to use the debug on android studio but it seems like the file needed isn’t found.  
so i took the old-way debug: i commented all of the related code and kept building it with decommenting it block by block (the crash only happens in build versions never a preview)  
it ended up being a crash due to the mapview. i made a very simple app that only has a mapview and it crashed too. i posted a new thread about it: [https://www.fusetools.com/community/forums/bug\_reports/mapview\_crash](https://www.fusetools.com/community/forums/bug_reports/mapview_crash)  
thank you so much.
