我对Flex Mobile应用程序的工作方式不熟悉，因此请在回复中进行描述。
我正在尝试为Android创建一个能够从我创建的服务应用程序接收意图的Flex Mobile应用程序。意图附加了一个字符串，我的应用程序获取该信息非常重要。但是，我似乎无法弄清楚如何使我的Flex应用程序接收服务应用程序发送的意图。
到目前为止，我已经尝试让应用程序暂停在原生Android端3秒钟，希望能够有足够的时间调用onReceive（）。这没用。
以下是我的代码。感谢您的帮助。
WiFi功能向服务发送意图以激活Android上的WiFi。
WiFi_info函数应该返回附加到此应用程序将接收的意图的数据。
ANESimpleApp.as - ActionScript库
package com.example.anesimpleapp
{
import flash.external.ExtensionContext;
public class ANESimpleApp
{
// This will hold the context for the Native Android side of the plugin
private var context:ExtensionContext;
// Get a context of the ANE
public function ANESimpleApp()
{
// Checks if the context was already setup
if(!context)
{
context = ExtensionContext.createExtensionContext("com.example.anesimpleapp", null);
}
}
// Turn On/Off the Wifi
public function WiFi(): void
{
context.call("WiFi", null);
}
// Get WiFi information
public function WiFi_Info(): String
{
return String (context.call("WiFi_info", null));
}
}
}
WiFi_info.java - 原生Android代码
public class WiFi_info implements FREFunction {
// This will retrieve information about the WiFi network the phone is currently connected to
public String connectionData = "EMPTY";
// This is used to reference the string value describing the WiFi network the phone is currently connected to.
public final String KEY_WiFi_Info = "Update_WiFi_Info";
// The expected intent
public final String WiFi_Data = "com.example.Obtain_WiFi_Data";
// Created a Runnable object

// This intent filter will allow the application to receive certain intents
IntentFilter filter = new IntentFilter();
// This allows the application to receive data about the WiFi
filter.addAction(WiFi_Data);
// Registers the BroadcastReceiver onReceive() in this app
context.getActivity().registerReceiver(mybroadcast, filter);
// Generates a 3 second pause
Thread myThread = new Thread(myRun);
myThread.start();

} catch (FREWrongThreadException e) {

return null;
}
// Unregisters the BroadcastReceiver (Don't want any leaked receivers)

{

我认为您的代码在3秒内无法正常暂停。看起来好像你正在启动另一个线程来做延迟，这意味着你的代码会在任何行动开始之前注册和取消注册接收器。
最好不要使用延迟，而是在实际的BroadcastReceiver onReceive函数中取消注册接收器。要做到这一点，您可能需要在扩展类 Extension.context 中存储对上下文的引用（尽管您可能已经这样做了）。
另外，我建议你将BroadcastReceiver分解为一个单独的类，以保持代码更清晰，你应该从比FREFunction更全局的地方引用它，例如在你的FREContext中。我将在这里写一些伪代码给你一个想法：
扩展：
public class ANEExtension implements FREContext
{
public static FREContext context;
public FREContext createContext(String arg0)
{
context = new ANEContext();
return context;
}
// Other functions...
}
上下文：
public class ANEContext implements FREContext
{
public WifiReceiver receiver = null;
public void registerWifiReceiver()
{
if (receiver == null)
{
receiver = new WifiReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction("com.example.Obtain_WiFi_Data");
getActivity().registerReceiver( receiver, filter );
}
}
public void unregisterWifiReceiver()
{
if (receiver != null)
{
getActivity().unregisterReceiver( receiver );
receiver = null;
}
}
// .. Map<> getFunctions etc...
}
功能类：
public class WiFi_info implements FREFunction
{
@Override
public FREObject call(FREContext context, FREObject[] object)
{
((ANEContext)context).registerWifiReceiver();
// return stuff...
return NULL;
}
}
接收者类：
public class WifiReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
if(intent.getAction().equalsIgnoreCase(WiFi_Data))
{
connectionData = intent.getStringExtra(KEY_WiFi_Info);
//
// Return Data
if (ANEExtension.context)
{
ANEExtension.context.dispatchStatusEventAsync(
"some:event:type",
connectionData
);
}
//
//
((ANEContext)ANEExtension.context).unregisterWifiReceiver();
}
}
}
编辑：为动作脚本侧的状态事件添加侦听器
以下是所有AS3代码，总结了从本机代码接收状态事件的重要部分。
public class WifiExtension extends EventDispatcher
{
public static const EXT_CONTEXT_ID : String = "the.extension.id";
public function WifiExtension()
{
_extContext = ExtensionContext.createExtensionContext( EXT_CONTEXT_ID, null );
_extContext.addEventListener( StatusEvent.STATUS, extension_statusHandler, false, 0, true );
}
private function extension_statusHandler( event:StatusEvent ):void
{
switch (event.code)
{
case "some:event:type":
trace( "The data from the native code = " + event.level );
}
}
}
