BroadCastReceiver(广播接收者)开机启动完成监听例子

 

一、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>

二、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);
  //必需要添加这个标签 不然启动失败
  intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  //跳转
  context.startActivity(intent1);
 }

}
