Improve Performance of PhoneGap Application

PhoneGap when combined with jQuery Mobile sometimes exhibits sluggish performance. Overriding some css from Jquery can give you better performance in terms of page loading, page transitions etc. It may not give a 100% improvement but it will definitely improve your app by a great extent.


Add the following code in your css:


/* disable shadows for better android performance */
.ui-body-a,
.ui-bar-a,
.ui-btn-up-a,
.ui-btn-hover-a,

And add the following code in your onDeviceReady event function:


function onDeviceReady() {


// for performance boosting
$.mobile.autoInitializePage = false;
$.mobile.defaultPageTransition = 'none';
$.mobile.touchOverflowEnabled = false;
$.mobile.defaultDialogTransition = 'none';

}

Clear Application cache in android

There are two ways you can remove your application cache which piles up during the active state of application and free your device memory from running low on space.

1)One way you can delete cache on app exit using the following code.

@Override
    public void onDestroy() {
        super.onDestroy();

        try {
            trimCache(this);
           // Toast.makeText(this,"onDestroy " ,Toast.LENGTH_LONG).show();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
    public static void trimCache(Context context) {
        try {
           File dir = context.getCacheDir();
           if (dir != null && dir.isDirectory()) {
              deleteDir(dir);
           }
        } catch (Exception e) {
           // TODO: handle exception
        }
     }

     public static boolean deleteDir(File dir) {
        if (dir != null && dir.isDirectory()) {
           String[] children = dir.list();
           for (int i = 0; i < children.length; i++) {
              boolean success = deleteDir(new File(dir, children[i]));
              if (!success) {
                 return false;
              }
           }
        }

        // The directory is now empty so delete it
        return dir.delete();
     }


2)Another way to manage cache is to listen for the ACTION_DEVICE_STORAGE_LOW broadcast through a &ltreceiver>.
