You can do this with a custom API. See this link: https://azure.microsoft.com/en-us/documentation/articles/mobile-services-how-to-use-server-scripts/#custom-api

Code looks like this:

exports.post = function(request, response) {
    response.send(200, "{ message: 'Hello, world!' }");
} 

It's then reachable at https://todolist.azure-mobile.net/api/APIFILENAME.

If you want to access a table you can do something like:

exports.post = function(request, response) {
    var userTable = tables.getTable('users');

    permissionsTable
        .where({ userId: user.userId})
        .read({ success: sendUser });
} 

function sendUser(results){
  if(results.length <= 0) {
    res.send(200, {});
  } else {
    res.send(200, {result: results[0]});
  }
}

You can then follow the instructions for using the API on your Android client here: https://azure.microsoft.com/en-us/documentation/articles/mobile-services-android-call-custom-api/

How your app is written will change how this code works/looks, but it looks something like:

ListenableFuture result = mClient.invokeApi( "UsersAPI", MarkAllResult.class ); 

That invokes the API. You need to write the class and Future to handle the results. The above page explains this in great detail.
