为android 启动的时候添加splash

In order to have a splash screen in a PhoneGap Android application you need to put your splash.png file into res/drawable-ldpi, res/drawable-mdpi, res/drawable-hdpi, res/drawable-xdpi. Where those directories represent low, medium, high and extra large dots per inch. You'll need to resize you slash.png for each directory or Android will stretch it for you.

The sizes of each image should be:

xlarge: at least 960 x 720
large: at least 640 x 480
medium: at least 470 x 320
small: at least 426 x 320
Then in your main Java class, the one that extends DroidGap, you'll need to add one line and modify another. First add:

super.setIntegerProperty("splashscreen", R.drawable.splash);

this line should show up under super.onCreate but before super.loadUrl. Then you'll need to modify your loadUrl method to pause for 5 seconds before loading up the main page. It would look like this:

super.loadUrl("file:///android_asset/www/index.html", 5000);

That should do it for you.
