接受开机广播和网络状态变化广播、电量相关广播

以下以网络状态变化广播示例：

直接创建一个广播接收器：

public class MyReceiver2 extends BroadcastReceiver {

    public MyReceiver2() {

    }

    @Override

    public void onReceive(Context context, Intent intent) {

        //获取系统网络服务状态

        ConnectivityManager conn = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo info= conn.getActiveNetworkInfo();

        String name = info.getType()+"";

        if(name != null){

            Toast.makeText(context,"网络断开",Toast.LENGTH_SHORT).show();

        }

    }

}

manifest：

<receiver

            android:name=".MyReceiver2"

            android:enabled="true"

            android:exported="true" >

            <intent-filter >

                <action android:name="android.intent.action.CONFIGURATION_CHANGED"/>

                    <category android:name="android.intent.category.DEFAULT"/>

            </intent-filter>

        </receiver>

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
