Crashes on load

[ptarjan]

I just got your plugin working, and now my app crashes on load with this:

What value you used for min_native_version, and what is set in the CFBundleVersion?

[ptarjan]

I had min_native_version set as 1, and I'm not sure what CFBundleVersion would be. In my config.xml I have version = 0.38.0

[ptarjan]

I should not, the error message above doesn't matter. If I delete the chcp.manifest it gives me a different error message on the first line but still crashes with the same body.

[nikDemyankov]

Strange. Will try to reproduce that and fix today.

[ptarjan]

Great thanks. It looks like one of those 4 values in my build is nil?

[nikDemyankov]

Yes, something went nil. When download fails - plugin prepares and sends notification to JavaScript. And it seems, that some value is nil in the preparation stage.

[nikDemyankov]

Most likely, you are missing some option in application config. Maybe content_url - it is either empty or doesn't exist in the configuration file.

I will add some additional checks for nil in that part of the plugin. But this will prevent app from crashing. If application config is wrong - plugin is not gonna load any updates.

[ptarjan]

Yes, I don't have the content_url option. How does it get inserted? From the config.xml? Is it the same?

But yeah, crashing is much worse than giving a good error message.

[nikDemyankov]

content_url - is server url, where all your project files are located. From it updates are loaded on the device. So this is a required preference for the plugin to work.

content_url should be a part of the application config. Url to the application config you define in your config.xml in config-file preference. When application launched - plugin loads data from config-file, checks if anything new is available, and if it is - uses content_url as a base path to the files from the manifest.

Please, look into documentation for more details.

Later today I'll add some additional info in the readme, since there are questions regarding configuration files. Some sort of step-by-step manual.

[ptarjan]

So if I'm doing a Cordova app is my content_url file://whatever_path_i_have_to_figure_out? Or is it my remote website? And how is the manifest location deduced? Same as the application config but changing the path TJ the predefined name?

All configs should be stored on the server, plus - your project files (www folder content).

You specify url to the application config by setting config-file preference in the config.xml of your application. Application config must have a content_url and release preferences.

content_url should point on the remote server. Manifest file location constructed like so: content_url/chcp.manifest. For example, if your content_url is https://mycooldomain.com, then manifest file url should be: https://mycooldomain.com/chcp.manifest.

When plugin detects changed files - it loads them from the server. Url to those files are constructed like so: content_url/path_to_file_from_manifest. More examples can be found in the documentation.

[ptarjan]

Ok, so how do config-file and content_url differ? Is config-file === conftent_url/chcp.json?

[nikDemyankov]

Usually - yes, config-file === content_url/chcp.json. But there are several main differences:

1. config-file is hard-coded into the config.xml of your application, while content_url can be changed at any time. You can even make it different for each new release.
2. config-file can be a script, that generates data on-the-fly, not a static file, like content manifest.
3. config-file and content_url can point on different servers. Why not? For example, your config-file is set to https://mydomain.com/mobile/release, and the content_url to https://storagedomain.com.

So, splitting them gives you a little more flexibility.

Fixed in version 1.0.3.
