💻 Code

Initializing the module

This will initialize the crash analytics module after com.appcelerator.aca has been added to tiapp.xml

const aca = require('com.appcelerator.aca');
Leaving Breadcrumb Trail

This code will help you track down any problems by allowing you to log where/what you have done in the app. These are only reported in the case of a handled exception or crash.

aca.leaveBreadcrumb('Opening screen:' + myscreen.id);
Adding User Metadata

This code will help you track down any problems by allowing you to log where/what your users have done in the app

aca.setUsername(username);
aca.setMetadata('lastLogin', datetime);
aca.setMetadata('gameLevel', 0);
Logging an Error (Handled Exception)

This code will allow you to track down exceptions/errors that may not cause a crash but are needed to help identify potential issues.

try {
var err = new Error('FATAL ERROR: Value cannot be null or undefined!');
if (value === null || value === undefined) throw err;
} catch (err) {
aca.logHandledException(err);
}
Allow User to Opt-Out

This code allows you to have to user opt-out of sending any crash analytics. Nothing will appear in report for this user if they do this.

// Disable sending data to Crash Analytics
aca.setOptOutStatus(true);
