BroadCastReceiver(广播接收者)开机启动完成监听例子

摘要: 一开机就实施广播监听

1、在配置清单里静态注册BroadCastReceiver

代码

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.broadcastreceiver.boot"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<!-- 添加开机启动完成的权限 -->
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- 静态注册广播接收者(实施监听) -->
<receiver
android:name=".BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>

=================

2、BootReceiver类

代码

public class BootReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub

Toast.makeText(context, "监听到开机完成", Toast.LENGTH_LONG).show();

Intent intent1 = new Intent(context,MainActivity.class);
//必须要添加这个标签 否则启动失败
intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//跳转
context.startActivity(intent1);
}

}
