Build properties not found for package Android SDK Platform 25

Hello @itinance. Thanks for this wonderful contribution to the open source world. Here is my package.json.

```
"dependencies": {
"react": "16.0.0",
"react-native": "0.51.0",
"react-native-fs":"^2.9.7",
"react-native-pages": "^0.6.1",
"react-native-static-server": "^0.2.4",
"react-native-zip-archive": "^2.2.1",
"react-navigation": "^1.0.0-beta.27",
"uglify-es": "3.2.2"
}
```

I'm running windows 10.

After I link the library and build my project, I encounter these issues:
**Build properties not found for package Android SDK Platform 25
`A problem occurred configuring project ':react-native-fs'. > Failed to find target with hash string 'android-25' in: C:\Users\Sumant\Android_SDK`**

Will the library only run with Android API v25 and above and if so how would I achieve this. If not is this the build tools version. I have all the SDK versions installed from 24 to 26. Any help on this is appreciated. Thank you.
