Android-WebApp

This is a library project to help build better webapp clients for Android. The library handles the generic details so that it's possible to create a webapp client with minimal effort.

Installation

Just clone this repository to any location accessible from your Android build environment.

Usage

Add the library to your Android project. Once done, your Activities can extend the com.bernatarlandis.android.webapp.WebAppActivity class. You only need to define the getHomeUrl method but any method can be overriden.

This is an example Activity:

package com.mycompany.mywebapp;

import com.bernatarlandis.android.webapp.WebAppActivity;

public class MainActivity extends WebAppActivity {

    @Override
    protected String getHomeUrl() {
        return "http://example.com";
    }
}

This is an example AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mycomppany.mywebapp"
    android:versionCode="1"
    android:versionName="1.0">
    <uses-permission android:name="android.permission.INTERNET" />
    <application android:label="@string/app_name" android:icon="@drawable/icon">
        <activity android:name="MainActivity"
            android:label="@string/app_name"
            android:configChanges="keyboardHidden|orientation|screenSize"
            android:theme="@android:style/Theme.NoTitleBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />
</manifest>

You can override the library resource strings in your project as needed, just declare them again with the same name.

The webapp will behave mostly like a browser but without the interface. Check the source code of WebAppActivity to see other methods you can override to change the default behavior.

A few examples:

• Override the getUserAgentString method if you want to change the default.
• Override the isInternalUrl to redefine what's an internal URL. Links to external URLs open in a browser window.
• Override the saveUrl/restoreUrl methods in case you don't want to start the webapp in the last visited page.

TODO

• Add permanent caching of JS/CSS resources.
