(android) not working well with other plugin

[zean00]

Just realise that this plugin will replace url scheme file:///android_aset/www into http://localhost/ for the android. This work just fine when the apps is pure javascript that will run completely in the browser. But when I combine this plugin with another plugin such as camera and geolocation, the problem shows up. The plugin seems unable to call the cordova API as it's using nodejs like require mechanism, so it will failed when the url is converted into http://localhost/

I found a workaround with this issue by partially encrypt the source, only the javascript of my apps that need to be encrypted. Just modify the file searching function of file to be encrypted, and change the source link of the url of the encrypted file from relative path to http://localhost/ (bower_components/js -> http://localhost/bower_components/js)

The downside is that I have to create separate project for the android and ios with this method, and if I want to encrypt the .html I have to refactor all the page link to include http://localhost schema , and I can't encrypt the index.html as it will convert everything into http://localhost schema (as the original plugin method)

I wish there will be a better solution and patch to this issue for the future. Anyway this plugin is very useful and thank you.

How to stop replacement of url scheme file:///android_aset/www into http://localhost/ for the android...I don't want to have http://localhost/ file system

[SoftWebProduction]

How do you tell to encrypt only your files? I tried replacing return fs.statSync(path.join(dir, file)).isFile() && /..(htm|html|js|css)$/.test(file); with: return fs.statSync(path.join(dir, file)).isFile() && /..(updates.js|logs.js)$/.test(file); but din't worked...

Below is my complete code after_prepare.js

    var path              = context.requireCordovaModule('path'),

        //console.log(file);
        if(platform == 'android' && isEncrypt(file))
            return fs.statSync(path.join(dir, file)).isFile() && /.*\.(js)$/.test(file);
        else if(platform == 'ios')
          return fs.statSync(path.join(dir, file)).isFile() && /.*\.(htm|html|css|js)$/.test(file);

after replacing my after_prepare.js with yours and using only 2 files on getCryptList(), when i run ionic build android --release i have the following error:

add to body class: platform-android

key=xxxxxxxxxxxxxxxxxxxxx, iv=xxxxxxxxxxxxxxxxxx

Error: Cannot read property 'forEach' of null

Do you have any clue?

I am also facing the same issue, @SoftWebProduction did you find solution ? please let me know
