android 设置开机启动

1. 写一个广播类， 用于接收系统开机启动的广播
 

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class XNBroadcastReceiver extends BroadcastReceiver{
	static final String action_boot="android.intent.action.BOOT_COMPLETED";
	@Override
	public void onReceive(Context arg0, Intent arg1) {
		// TODO Auto-generated method stub
		if (arg1.getAction().equals(action_boot)){ 
			Intent service = new Intent(arg0, PhoneService.class);
			arg0.startService(service);
		}
	}
}

2.在manifest里面注册广播，设置开机权限

 <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
        <!-- 声明服务 -->
        <service android:name=".PhoneService"></service>
        <!-- 注册开机启动广播 -->
        <receiver android:name=".XNBroadcastReceiver">
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <category android:name="android.intent.category.LAUNCHER" /> 
            </intent-filter>
        </receiver>

3.在广播类里面的onReceive（）中写我们开机需要做的东西
