Webview+

This project is a plugin for cordova apps, and provides a uniform webview on any Android 4.x device..

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:

$ cd /to/your/cordova/based/project
$ cocoonjs plugin add com.ludei.webview.plus

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. Will be fixed for next version
  • In some devices 3D context may not be created, this is due to a memory limitation of the device.
