Android4.4：

静态广播：

可在AndroidManifest.xml中定义，不需程序启动即可接收，可用作自动启动程序

Intent.ACTION_BOOT_COMPLETED //系统启动完成

Intent.ACTION_MEDIA_MOUNTED //SD卡挂载

Intent.ACTION_MEDIA_UNMOUNTED //SD卡卸载

Intent.ACTION_USER_PRESENT//解除锁屏

ConnectivityManager.CONNECTIVITY_ACTION//网络状态变化

<receiver android:name=".StaticBroadcastReceiver">            <intent-filter>                <action android:name="android.intent.action.BOOT_COMPLETED" />                <category android:name="android.intent.category.HOME" />            </intent-filter>            <intent-filter>                <action android:name="android.intent.action.MEDIA_MOUNTED"/>                <action android:name="android.intent.action.MEDIA_UNMOUNTED"/>                <category android:name="android.intent.category.DEFAULT" />                <data android:scheme="file" />            </intent-filter>            <intent-filter>                <action android:name="android.net.conn.CONNECTIVITY_CHANGE" /><action android:name="android.intent.action.USER_PRESENT" />            </intent-filter></receiver>

public class StaticBroadcastReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubif (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){Log.d(TAG, "onReceive boot: ");Intent new_intent = new Intent(context,TestLauncher.class);//popup the activitynew_intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);context.startActivity(new_intent);}else if(intent.getAction().equals(Intent.ACTION_USER_PRESENT)) {Log.d(TAG, "onReceive ACTION_USER_PRESENT: ");}}}

动态广播：

只能在代码中注册，程序适应系统变化做操作，程序运行状态才能接收到

Intent.ACTION_SCREEN_ON //屏幕亮

Intent.ACTION_SCREEN_OFF //屏幕灭

Intent.ACTION_TIME_TICK //时间变化每分钟一次

<span style="white-space:pre"></span>    IntentFilter filter = new IntentFilter();    filter.addAction(Intent.ACTION_SCREEN_ON);    filter.addAction(Intent.ACTION_SCREEN_OFF);    filter.addAction(Intent.ACTION_TIME_TICK);    registerReceiver(new DynamicBroadcastReceiver(), filter);
