After adding the cordova-plugin-ionic-webview, navigate to the following location: 20 | 21 | For cordova-android@6 : 22 | 23 | **platforms/android/src/com/ionicframework/cordova/webview/IonicWebViewEngine.java** 24 | 25 | For cordova-android@7 : 26 | 27 | **platforms/android/app/src/main/java/com/ionicframework/cordova/webview/IonicWebViewEngine.java** 28 | 29 | 2. Remove the following code: 30 | 31 | ``` 32 | @RequiresApi(Build.VERSION_CODES.LOLLIPOP) 33 | @Override 34 | public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) { 35 | super.shouldInterceptRequest(view,request); 36 | return localServer.shouldInterceptRequest(request.getUrl()); 37 | } 38 | 39 | @TargetApi(Build.VERSION_CODES.KITKAT) 40 | @Override 41 | public WebResourceResponse shouldInterceptRequest(WebView view, String url) { 42 | return localServer.shouldInterceptRequest(Uri.parse(url)); 43 | } 44 | ``` 45 | 3. Add this instead: 46 | 47 | ``` 48 | @Override 49 | public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) { 50 | return super.shouldInterceptRequest(view, request); 51 | } 52 | ``` 53 | 54 | Then the plugin will work. 55 | 56 | ## Configuration 57 | 58 | You can also change the port in the `config.xml`, but it needs to be the same port as the one used in the "cordova-plugin-ionic-webview". 59 | 60 | To change the port, do the following: 61 | 62 | #### cryptoPort 63 | 64 | ```xml 65 | 66 | ``` 67 | 68 | ## Encrypt 69 | `cordova build [ios / android]` 70 | 71 | ## Decrypt 72 | `cordova emulate [ios / android]` 73 | or 74 | `cordova run [ios / android]` 75 | 76 | ## Encryption subjects. 77 | 78 | ### Default 79 | 80 | * .html 81 | * .htm 82 | * .js 83 | * .css 84 | 85 | ### Edit subjects 86 | 87 | You can specify the encryption subjects by editing `plugin.xml`. 88 | 89 | **plugins/cordova-plugin-crypt-file/plugin.xml** 90 | 91 | ``` 92 | 93 | 94 | 95 | 96 | 97 | 98 | 99 | 100 | ``` 101 | 102 | Specify the target file as a regular expression. 103 | 104 | 105 | ## Supported platforms 106 | * iOS 107 | * Android 108 | * CrossWalk 109 | 110 | 111 | ## Based on the original cordova-crypt-file created by tkyaji 112 | 113 | https://github.com/tkyaji/cordova-plugin-crypt-file 114 | 115 | ## License 116 | Apache version 2.0 117 | -------------------------------------------------------------------------------- /hooks/after_prepare.js: -------------------------------------------------------------------------------- 1 | module.exports = function(context) { 2 | 3 | var path = require('path'), 4 | fs = require('fs'), 5 | crypto = require('crypto'), 6 | Q = require('q'), 7 | cordova_util = context.requireCordovaModule('cordova-lib/src/cordova/util'), 8 | platforms = context.requireCordovaModule('cordova-lib/src/platforms/platforms'), 9 | ConfigParser = context.requireCordovaModule('cordova-common').ConfigParser;
