Android StudioでSDKを入れた場合した場合、通常は以下に配置されている

$ ~/Library/Android/sdk

1	$ ~/Library/Android/sdk

.bash_profileにANDROID_HOMEを追加する。

$ echo 'export ANDROID_HOME=~/Library/Android/sdk' >> ~/.bash_profile
$ echo 'export PATH=$ANDROID_HOME/bin:$PATH' >> ~/.bash_profile
$ echo 'export PATH=$ANDROID_HOME/platform-tools:$PATH' >> ~/.bash_profile

$ echo 'export ANDROID_HOME=~/Library/Android/sdk' >> ~/.bash_profile

$ echo 'export PATH=$ANDROID_HOME/bin:$PATH' >> ~/.bash_profile

$ echo 'export PATH=$ANDROID_HOME/platform-tools:$PATH' >> ~/.bash_profile

再読込

$ source ~/.bash_profile

1	$ source ~/.bash_profile

ANDROID_HOMEが設定されたことを確認

$ echo $ANDROID_HOME
$ echo $PATH

1 2	$ echo $ANDROID_HOME $ echo $PATH

Unhandled JS Exception: Application odc has not been registered.

Unhandled JS Exception: Application odc has not been registered.

Hint: This error often happens when you're running the packager (local dev server) from a wrong folder. For example you have multiple apps and the packager is still running for the app you were working on before.
If this is the case, simply kill the old packager instance (e.g. close the packager terminal window) and start the packager in the correct app folder (e.g. cd into app folder and run 'npm start').

This error can also happen due to a require() error during initialization or failure to call AppRegistry.registerComponent.

プロセスを確認してkillしてみる？

ps aux | grep react

1	ps aux \| grep react

Could not connect to development server

Android端末をネットワークに繋いでなかった。。USB経由でよろしくやってはくれなさそう？

adb reverse error closed

Android 5.0以下だとadb reverseに対応していないため発生する問題のようです。Wifi接続する手段があるようなのでそれで対応。

開発マシンと開発端末を同じWi-Fiネットワークに接続する
開発マシンのIPアドレスを確認する
react-native run-android を実行して開発端末でアプリを起動する
アプリがエラー画面となるのでdismissを押下する
開発端末のメニューボタンを押下してDev Settingsを選択する
Debug server host & port for dev で、IPアドレス:ポート番号を選択する
（IPアドレスは2.で確認した開発マシンのIP、ポートは特に変更していなければ8081）
