I am trying to compile my .apk and I get this:

 ![file](https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/LKVKIAzDo4mg-image-1487011415844.png)

I have been stuck for hours with foreign code. What I want is to add an event to the calendar from JS, passing the start date and end date as parameters.

As the error says you don’t have `context` available. When doing foreign code you can get the Activity / Context as described [here](https://www.fusetools.com/docs/native-interop/foreign-code#getting-the-root-activity).

E.g. this should work: `com.fuse.Activity.getRootActivity().startActivity(intent)` 🙂
