React Nativeとはいえ、モジュールを使うとネイティブのコードが沢山追加されます。
だから何もしなくても勝手にクロスプラットフォーム対応！とは世の中そう上手くいきません。世知辛ぇよ。
だから先にiOSアプリをひと通り実装してから、いざAndroidアプリをビルドしてみると・・出るわ出るわエラーが笑
筆者がまさにそういうやり方でアプリ作っているので、Androidビルドで生まれた魑魅魍魎たちの退治記録を以下にまとめました。ご参照下さい。
Android SDK Build Tools revision 23.0.1 が必要と怒られる
RNのバージョンによって要求されるSDKも異なるかもしれません。
こんな風に怒られます：
> react-native run-android
JS server already running.
Building and installing the app on the device (cd android && ./gradlew installDebug)...
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':app'.
> failed to find Build Tools revision 23.0.1
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
Total time: 3.994 secs
Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html
という訳でインストールしてあげます。
以下でインストールできるsdkの一覧を取得する。
> android list sdk -a
リスト左の番号を-tオプションに指定してインストール：
> android update sdk -a -u -t 12
androidコマンドなんて無ぇよと言われる
SDKのバージョンが新しいと、androidコマンドを実行すると以下のように怒られます：
The android command is no longer available.
For manual SDK and AVD management, please use Android Studio.
For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager
おとなしくAndroid Studioからインストールしてください。

これはAndroid StudioでAndroid SDKを最新に更新してあげれば解決しました。

react-native-webview-bridgeは使っていないモジュール。リンクしたままだったので怒られた。android/app/build.gradleから該当のcompileステートメントを削除。
