그리고 이동 중에는 Wi-Fi를 off합니다.
그래서 자동으로 충전 중이면 Wi-Fi를 켜주고 충전이 아니면 Wi-Fi를 끄는 app을 만들어 봤습니다.
추가적으로 빈 Activity에 사용여부 확인 가능한 checkbox를 추가하였습니다.

아주 간단한 프로그램인데 BroadcastReceiver 상속받은 class만으로 app을 만들어 보니 ACTION_POWER_CONNECT intent를 못 받아서 삽질 좀 했네요.
그래서 아무 동작하지 않는 Activity를 추가 하였습니다.
--- ACConnectReceiver.java ---
package com.hardkernel.odroid.wifiauto;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.wifi.WifiManager;
public class ACConnectReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String action = intent.getAction();
WifiManager manager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
if (action.equals(Intent.ACTION_POWER_CONNECTED)) {
manager.setWifiEnabled(true);
} else if (action.equals(Intent.ACTION_POWER_DISCONNECTED)) {
manager.setWifiEnabled(false);
}
}
}
--- MainActivity.java ---
