Android 广播(Broadcast)程序开机自启动

学习这个“通过广播开机自启动”知识点时忽略了手机本身“设置”里面自启动权限的没有打开，害得我思考好久。

package com.xxx.study;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class BootTestActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}

}

package com.xxx.study;

import android.R.anim;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.text.AndroidCharacter;

public class BootCompletedReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
System.out.println("@@@@@@");

if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED"))
{
System.out.println("@@@@@@...bootComplete!");
Intent newIntent = new Intent(context, BootTestActivity.class);
newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  //注意，必须添加这个标记，否则启动会失败
context.startActivity(newIntent);

}
}
}
