获取错误:找不到方法com.urbanairship.Autopilot.automaticTakeOff

Question

我想用UrbanAirship最新的软件开发工具包创建一个文件。我已经在应用程序块下的app-xml中添加了Autopilot元数据(<meta-data android:name="com.urbanairship.autopilot" android:value="com.sample.aneAndroid.TakeOffHelper" /> )，还创建了Autopilot的子类并在其中添加了AirshipConfigOptions。当我试图在实现FREFunction的类中调用Autopilot.automaticTakeOff(app);时，它给出了以下错误-

02-03 17:14:11.949  23088-23088/? I/dalvikvm﹕ Could not find method com.urbanairship.Autopilot.automaticTakeOff, referenced from method com.sample.aneAndroid.UAPushNotificationExtensionSubscribeFunction.call
02-03 17:14:11.949  23088-23088/? W/dalvikvm﹕ VFY: unable to resolve static method 3322: Lcom/urbanairship/Autopilot;.automaticTakeOff (Landroid/app/Application;)V

TakeOffHelper.java

@Override
    public AirshipConfigOptions createAirshipConfigOptions(Context context) {
        Log.v("Autopilot", "createAirshipConfigOptions called");
        AirshipConfigOptions options = AirshipConfigOptions.loadDefaultOptions(context.getApplicationContext());
        Log.v("Autopilot", "createAirshipConfigOptions called " + options);
        return options;
    }

    @Override
    public void onAirshipReady(UAirship airship) {
        Log.v("Autopilot", "onAirshipReady called");
         DefaultNotificationFactory defaultNotificationFactory = new DefaultNotificationFactory(UAirship.getApplicationContext());
        defaultNotificationFactory.setColor(NotificationCompat.COLOR_DEFAULT);

        // Set it
        airship.getPushManager().setNotificationFactory(defaultNotificationFactory);

        // Enable Push
        airship.getPushManager().setPushEnabled(true);

    }

UAPushNotificationExtensionInitFunction.java

public FREObject call(FREContext context, FREObject[] args) {

        UAPushNotificationExtensionContext nec = (UAPushNotificationExtensionContext) context;
        android.app.Activity activity = nec.getActivity();
        nec.activity = activity;

         Application app = context.getActivity().getApplication();
         Autopilot.automaticTakeOff(app);}

这可能是由于错误的.jar文件造成的。我使用以下格式的命令来构建ANE：

adt -package -target ane bin/airshipWrapper.ane src/extension.xml -swc lib/airshipWrapper.swc -platform Android-ARM -C working/android . -platform default -C working/default .

bin/airshipWrapper.ane是ANE的目标位置

src/extension.xml是您尝试构建的ANE的extension.xml路径

lib/airshipWrapper.swc是指向swc的路径，其中包含ANE的ActionScript类(这是您放置调用ExtensionContext.createExtensionContext()的类的位置)。

working/android是包含airshipWrapper.jar和library.swf的路径

airshipWrapper.jar是一个包含您的Java类和所有需要的库类的组合jar文件。

从您的airshipWrapper.swc中提取library.swf。

working/default是包含与airshipWrapper.swc中的类具有相同签名的library.swf的路径(这样当您在模拟器中运行项目时，它就不会中断)

*对于jar文件，我从我的Java项目中导出它，然后使用任何必要的库类运行jar更新。我使用的是ant，但是任何从一个jar中提取类并更新另一个jar的方法都可以。
