Looking for Webview+ for iOs?

Webview+ Features, Advantages and Benefits

V8 Javascript VM
Works on Android 4.x
Latest HTML5 APIs
Compatible with Cordova Plugins
Better performance than system webview

Prerequisites

You'll need android SDK API level 19 installed in with your SDK tools.

How to install the Webview+ in your current project

Even though it's a cordova-compatible plugin, some steps must be done for the installation. If you prefer, you can install it automatically using the CocoonJS Command Line Interface.

The cocoonjs-cli has the same usage and commands of cordova-cli.

Once the cocoonjs-cli is installed in your system, just type:

// Install Ludei's CLI
$ sudo npm install -g cocoonjs

$ cocoonjs create MyProject
$ cd MyProject
$ cocoonjs platform add ios
$ cocoonjs plugin add com.ludei.webview.plus -d
$ cocoonjs run/emulate

The -d flag is used to activate the verbose mode.

Manual installation

The CocoonJS-CLI automates the installation of the Webview+, but if for some reason you want to install the Webview+ without the CocoonJS-CLI you’ll have to do the following steps.

These steps are specific for Cordova 3.4.0 and higher. If you want to install manually Webview+ in previous versions, please, refer to the hooks in the cocoonjs-cli

Step 1

Clone the Webview+ repository in your computer:

git clone https://github.com/ludei/webview-plus.git

Step 2

Edit the following file by using your favorite text editor

_PATH_TO_YOUR_CORDOVA_PROJECT_/platforms/android/CordovaLib/src/org/apache/cordova/CordovaWebview.java

Step 3

Find the following string inside CordovaWebview.java:

public class CordovaWebView extends WebView

Step 4

Replace the string you've found with these two strings:

import com.ludei.chromium.LudeiWebView;
public class CordovaWebView extends LudeiWebView

Save and close the file

Step 5

Edit the following file:

_PATH_TO_YOUR_CORDOVA_PROJECT_/platforms/android/CordovaLib/project.properties

Step 6

Paste the following string and change the path after “android.library.reference.1=” to the relative path that points to your downloaded Webview+ (It must be a relative path and not an absolute path)

android.library.reference.1=../../../plugins/com.ludei.webview.plus/android

There you go. Now that you have installed the Webview+ in your project you can run the command “$ cordova build” and your app will benefit of the advantages of the Webview+.

If you want to know how the CocoonJS-CLI does these steps programatically, check the sources at android/hooks folder (after_plugin_add / after_plugin_rm).

Known bugs

Launching the Webview+ inside android's emulator can lead to an application crash. Use a real device for testing.
Current version may not reproduce sound files.
In some devices 3D context may not be created, this is due to a memory limitation of the device.
As android SDK API level 19 is required, if it is not installed properly in the machine, it will raise an "Unable to resolve project target 'Google Inc.:Google APIs:19'" compilation error. Here it is a step-by-step guide to solve this issue.
