How to communicate with a car via Android smartphone?
<p>I want to start an app to be used by an Android smartphone to send information to a car. One example would be to unlock the car, but that is not precisly what I want to do is just an example. My question is, how can I communicate with the car? I am thinking of using a webservice, don't know if this would be adecuate for the prototype.</p>

<p>I would appreciate some links, or info to point me in the right direction to enable a communication of some sort with the car, that is adding a modem to the car or something, I don't know much about how to be able to communicate. </p>

<p>Is there a way to communicate in a longer distance, that is not using bluetooth, since bluetooth is for short distances?</p>

<p>Thanks!</p>
