Android how to access the same object through different activities
<p>With <code>Firebase</code> database and user object, it's possible to load every information from the database whenever the user navigates through different activities but to save some time it seems more effective for the data to be loaded on the <code>MainActivity</code> and put into one object (like <code>user.setProfile</code>) and for that object to be accessed from every <code>Activity</code>. Is this possible and how ? (a simple example would be very appreciated ).</p>
