广播

package com.example.text16;

import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.net.Uri;import android.util.Log;

//应用安装卸载的广播接收者public class AppInstallReceiver extends BroadcastReceiver{

@Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); //获取的包名 Uri data = intent.getData(); if ("android.intent.action.PACKAGE_ADDED".equals(action)) { Log.e("TAG", "install-->"+data); } else if ("android.intent.action.PACKAGE_REMOVED".equals(action)) { Log.e("TAG", "removed-->"+data); }{

} }

}

package com.example.text16;

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

//开机启动的广播接收者public class BootReciver extends BroadcastReceiver{

@Override public void onReceive(Context context, Intent intent) { Log.e("TAG", "开机了"); Intent i = new Intent(context,MainActivity.class); /*** * 现在是在广播接收着中创建activity * 当前没用任何activity在运行，所以不存在的一个任务栈 * 需要制定义flag，在创建activity的同时创建任务栈 */ i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK); context.startActivity(i); }

}

package com.example.text16;

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

//ip拨号器的广播接收者public class DialReceiver extends BroadcastReceiver{

@Override public void onReceive(Context context, Intent intent) { // 获取电话 String number = getResultData(); //// Log.e("Tag", "打电话"+number); //设置拨打的电话号 setResultData(number); }

}

package com.example.text16;

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

//监听SD卡挂在状态的广播接收者public class SDCarStateReceiver extends BroadcastReceiver {

} }

}

package com.example.text16;

import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.telephony.SmsMessage;import android.telephony.gsm.SmsManager;import android.util.Log;

//短信广播接收者public class SMSReceiver extends BroadcastReceiver{
