[ma1069]

In order to make this library working on React Native 0.25, you need to add these lines of code after line 20 of index.android.js:

      renderToHardwareTextureAndroid: PropTypes.bool,
      onLayout: PropTypes.bool,
      importantForAccessibility: PropTypes.bool,
      accessibilityLabel: PropTypes.string,
      accessibilityLiveRegion: PropTypes.string,
      accessibilityComponentType: PropTypes.string,
      testID: PropTypes.string,

just leaving this note here, waiting for someone to perform a proper pull request
