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-xhdpi. Where those directories represent low, medium, high and extra large dots per inch. You’ll need to resize you splash.png (the file name is important here) for each directory or Android will stretch it for you.
The sizes of each image should be:
- xlarge (xhdpi): at least 960 x 720
- large (hdpi): at least 640 x 480
- medium (mdpi): at least 470 x 320
- small (ldpi): 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.
I’ve recently made some updates to how the SplashScreen works on PhoneGap Android. The main app now loads while the splash screen is being shown. This is a big improvement over the previous blocking splash screen call. Read more about the changes on my blog.
