Enter fee manually by tapping the fee rate next to the slider.
In order to achieve this, I changed the fee rate text from TextView to EditText. Added a "sats/b" TextView next to it.
In SendActivity.java, I created a TextWatcher so that every time the user enters a fee rate manually, it updates on the slider next to it. I also created two OnClickListeners for both the "sats/b" and "Low/Normal/High" texts so that when the user taps on any of them, the fee rate number pad opens.
