How to assign a link or path to a button in drupalgap?
Try this in your hook_block_view():

var content = '&lt;div data-role="navbar"&gt;';
content += theme('item_list', {
  items: [
    l('Home', '', { attributes: { 'data-icon': 'home' } }),
    l('Saved', 'node/1029', { attributes: { 'data-icon': 'action' } }),
    l('Sponsors', 'node/969', { attributes: { 'data-icon': 'star' } }),
    l('Setup', 'node/1021', { attributes: { 'data-icon': 'gear' } })
  ]
});
content += '&lt;/div&gt;';
return content;


Whenever linking in DrupalGap, the key is to use the l() or bl() functions which will properly assemble a link or button link for you. Here's the docs page with more info: http://docs.drupalgap.org/7/Pages/Navigating_Pages
