Changes needed for gradle 3.0.1 compatibility

[pacamara]

Some minor changes are needed for gradle 3.0.1 compatibility: in android/build.gradle:

• Remove the buildToolsVersion, gradle now specifies a default and the current value conflicts with that.
• Declare dependencies using api not compile per https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html#new_configurations

We are currently hacking these changes with a script in status.im, and would rather it is fixed upstream. Thanks!

Hi @pacamara, I recently received access to update this package on NPM, but don't have access to this repo on github. We're going to be supporting this package at https://github.com/aprock/react-native-os. Would you mind open this issue there or maybe updating the source with a PR?

Hi @phillbaker , thanks. A PR has now been opened for this upstream against react-native: facebook/react-native#17747

I'd suggest the gradle upgrade for react-native-os is postponed until such time that gets merged, please see discussion at software-mansion/react-native-svg#581
