class HomeScreen extends React.Component {

  onSelect (data) {
    this.setState(data);

in some case, you cant call refs and get error:

undefined is not a function(evaluating'_this.refs.ModalPicker.onOpen()')

to solve this issue.

Để release cho google signin phải add mã sha1 release chứ không phải mã sha1 như lúc debug.

Bước 1: tạo my-release-key.keystore

tạo key này như hướng dẫn của bên docs (https://facebook.github.io/react-native/docs/signed-apk-android.html)

thì phải vô đường dẫn này C:\Program Files\Java\jdkx.x.x_x\bin. (trên windows)

còn trên mac sẽ là /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/bin/keytool (trên mac)
