Description

Problem Description:

Unable to access method getApplicationContext in android.content.Context class using Hyperloop while trying to use thord party library Localytics for Android. (attached the third party library as well)

Steps to reproduce:

1. Create a classic app and enable Hyperloop. 2. Run the attached (app.js) code. 3. You will see the below error message:

[ERROR] :  TiExceptionHandler: (main) [42,42] ----- Titanium Javascript Runtime Error -----
[ERROR] :  TiExceptionHandler: (main) [0,42] - In /app.js:5,56
[ERROR] :  TiExceptionHandler: (main) [0,42] - Message: Uncaught SyntaxError: Invalid or unexpected token
[ERROR] :  TiExceptionHandler: (main) [0,42] - Source: var appContext = (new context).getApplicationContext();
[DEBUG] :  OpenGLRenderer: Use EGL_SWAP_BEHAVIOR_PRESERVED: true

[ERROR] :  V8Exception: Exception occurred at /app.js:5: Uncaught SyntaxError: Invalid or unexpected token

Expected Result:

To be able to get the ApplicationContext in order to use it for localytics method parameter.

[~nmishra], the code they are using is wrong. android.content.context is an abstract class which cannot be instantiated. Also it is not possible to hook into the application's onCreate method from Hyperloop, which is the designated place to run Localytics.autoIntegrate() according to the documentation of the Localytics SDK. They can try this, but it won't log the first activity launched.

   var Activity = require('android.app.Activity');
   var currentActivity = new Activity(Ti.Android.currentActivity);
   var Localytics = require('com.localytics.android.Localytics');
   Localytics.autoIntegrate(currentActivity.getApplicationContext());
   Localytics.setLoggingEnabled(true);
   // Example how to use listeners
   var AnalyticsListenerAdapter = require('com.localytics.android.AnalyticsListenerAdapter');
   var listener = new AnalyticsListenerAdapter({
       localyticsSessionWillOpen: function(isFirst, isUpgrade, isResume) {
       // ... do something ...
       Ti.API.debug('Localytics session will open');
     }
   });
   Localytics.setAnalyticsListener(listener);

For a full integration they could write a module, place the Localytics SDK there and include a method annotated with @Kroll.onAppCreate where the Localytics SDK can be properly initialized. After that they can then continue to use Hyperloop to make all other calls to the Localytics SDK.

It's a key provided by Localytics to identify the app. Please see their docs: https://docs.localytics.com/dev/android.html#modify-androidmanifest-android and our docs how to add that: http://docs.appcelerator.com/platform/latest/#!/guide/Maintaining_a_Custom_AndroidManifest.xml
