有序广播先定义先接收

abortBroadcast();忽略广播  

可以通过android:priority制定优先级  不写为0

可以设置是否接收其他app的广播

可以设置是否被其他app接收广播 本地广播LocalBroadcastManager

private LocalBroadcastManager manager= LocalBroadcastManager.getInstance(this);

LocalReceiver receiver=new LocalReceiver();

IntentFilter filter=new IntentFilter();

filter.addAction("com.example.wkp.broadcast.MY_ACTION");

manager.registerReceiver(receiver,filter);
