How to notify FxOS app when the whole app crashed

Question

Is there a way that we can be notified when the whole FxOS app crashes? Because I want to know what causes it to crash or errors.

Thanks.

Answer 1

There is no API that will report what crashed your app. Why? Because you should've known better or have treated possible errors offhand.

What I would recommend is that you log your actions somehow. One of your options is using the Console API, which is something like this:

Outputting a single object

var someObject = { str: "Some text", id: 5 }; console.log(someObject);

This will output something like

[09:27:13.475] ({str:"Some text", id:5})

Stack Traces

The console object also supports outputting a stack trace, which will show you the call path taken to reach the point at which you've called console.trace() . It goes like this

foo();

function foo() {
  function bar() {
    console.trace();
  }
  bar();
}

And console will output something like this:
