Android连接延迟更改广播

Question

我正在听＆＃34; android.net.conn.CONNECTIVITY_CHANGE＆＃34;在我的应用程序与广播接收器。它确实有效，但我唯一的问题是收到这个广播有很大的延迟。应用程序接收此广播需要1-2秒。难道我做错了什么？ 我的清单条目 -

let fileUrl = NSURL(fileURLWithPath: "/tmp/foo.plist") // Your path here
let array = [["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"], ["One", "Two", "Three"]] // Your array of arrays here

// Save to file
(array as NSArray).writeToURL(fileUrl, atomically: true)

// Read from file
let savedArray = NSArray(contentsOfURL: fileUrl) as! [[String]]

print(savedArray)

和ConnectivityBroadcastReceiver类 -

<receiver android:name=".ConnectivityBroadcastReceiver"
            android:exported="true">
            <intent-filter>
                <action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
            </intent-filter>
</receiver>
