Android tip. Update UI everywhere.

How to update UI in some non-main threads?

Solution 1:

Use Handler and send Message.

Solution 2:

Force to run on UI thread.

new Thread() {
    public void run() {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                // Update UI here
            }
        });
    }
}.start();

When I used Handler, the Android Studio warned me that it might cause leak, so I chose to use solution 2.
