Cordova入门浅析

目录结构

查看安卓的项目，只有两个module:
app和CordovaLib;

入口

代码的入口，只有一个就是MainActivity;

public class MainActivity extends CordovaActivity
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        // enable Cordova apps to be started in the background
        Bundle extras = getIntent().getExtras();
        if (extras != null && extras.getBoolean("cdvStartInBackground", false)) {
            moveTaskToBack(true);
        }

        // Set by <content src="index.html" /> in config.xml  
        这是重点。
        loadUrl(launchUrl);
    }
}

查看方法：

 /**
     * Load the url into the webview.
     */
    可以直接认为是使用cordova自定义的WebView来加载一个url
    public void loadUrl(String url) {
        if (appView == null) {
            init();
        }

        // If keepRunning
        this.keepRunning = preferences.getBoolean("KeepRunning", true);

        appView.loadUrlIntoView(url, true);
    }

  @SuppressWarnings("deprecation")
    protected void loadConfig() {
        ConfigXmlParser parser = new ConfigXmlParser();
        parser.parse(this);
        preferences = parser.getPreferences();
        preferences.setPreferencesBundle(getIntent().getExtras());  
      在父类中进行了赋值
        launchUrl = parser.getLaunchUrl();
        pluginEntries = parser.getPluginEntries();
        Config.parser = parser;
    }

继续向上找：

    其实就是加载了asset下边的index.html.
    private String launchUrl = "file:///android_asset/www/index.html";
    private CordovaPreferences prefs = new CordovaPreferences();
    private ArrayList<PluginEntry> pluginEntries = new ArrayList<PluginEntry>(20);

    public CordovaPreferences getPreferences() {
        return prefs;
    }

    public ArrayList<PluginEntry> getPluginEntries() {
        return pluginEntries;
    }

    public String getLaunchUrl() {
        return launchUrl;
    }

而assets就是我们写的代码。
