Xamarin.android 在Mono中使用JNI访问Java库

我正在为Android开发一个使用mono的应用程序，一直在努力让推送通知生效，我正在使用城市飞艇

到目前为止，我已经能够调用TakeOff（）和EnablePush（），并且我的应用程序正在成功注册，请参阅以下代码：

 //_____________________________
 // Get the airship config class
    IntPtr ip_airshipConfigOptions = JNIEnv.FindClass("com/urbanairship/AirshipConfigOptions");

   if (ip_airshipConfigOptions == IntPtr.Zero)
   {
         throw new InvalidOperationException("Counldn't find java class !");
   }

                //__________________________________________________
                // Get the loadDefaults method from the config class
                IntPtr methodId = JNIEnv.GetStaticMethodID(ip_airshipConfigOptions, "loadDefaultOptions", "(Landroid/content/Context;)Lcom/urbanairship/AirshipConfigOptions;");

                if (methodId == IntPtr.Zero)
                {
                    throw new InvalidOperationException("Couldn't find java class !");
                }

                //________________________________________________________________
                // Call the loadDefaultOptions method passing in this app instance
                var methodPtr = JNIEnv.CallStaticObjectMethod(ip_airshipConfigOptions, methodId, new JValue(this));

                //________________________
                // Get the UAirship class
                IntPtr ip_uairship = JNIEnv.FindClass("com/urbanairship/UAirship");

                if (ip_uairship == IntPtr.Zero)
                {
                    throw new InvalidOperationException("Couldn't find java class !");
                }

                //___________________________________________
                // Get takeOff method with configoption param
                IntPtr methodId2 = JNIEnv.GetStaticMethodID(ip_uairship, "takeOff", "(Landroid/app/Application;Lcom/urbanairship/AirshipConfigOptions;)V");

                //______________________________________________
                // Get takeOff method without configoption param
                //IntPtr methodId3 = JNIEnv.GetStaticMethodID(ip_uairship, "takeOff", "(Landroid/app/Application;)V");

                //___________________________________________________________________________________________
                // Call UAirship.takeOff(this, options). Not sure if these parameters are specified correctly 
                JNIEnv.CallStaticVoidMethod(ip_uairship, methodId2, new JValue(this), new JValue(methodPtr));

                //________________________________________
                // Enable Push in Urban Airship Pushmanager     
                IntPtr ip_pushmanager = JNIEnv.FindClass("com/urbanairship/push/PushManager");
                IntPtr ip_enablePush = JNIEnv.GetStaticMethodID(ip_pushmanager, "enablePush", "()V");
                JNIEnv.CallStaticVoidMethod(ip_pushmanager, ip_enablePush);

我现在需要调用PushManager.shared（）.setIntentReciever（myClass），但我似乎无法访问shared（）类或setIntentReciever方法。我已经尝试了各种组合来尝试访问该方法，但始终得到类/方法未发现异常

//IntPtr ip_setReciver = JNIEnv.GetStaticMethodID(ip_PushManager, "shared().setIntentReceiver", "(Landroid/app/Class)V");

感谢您的帮助！我相信它可以用一行来解决，我想我只是缺少了一些语法

关于解决此问题，请参阅下面通过JNI调用setIntentReceiver的代码：

//__________________________
// Get the PushManager class
IntPtr ip_Test = JNIEnv.FindClass("com/urbanairship/push/PushManager");

//_____________________
// Get the class object
IntPtr ip_class = JNIEnv.GetObjectClass(ip_Test);

//_________________________________
// Get the setIntentReciever method
IntPtr ip_setIntent = JNIEnv.GetMethodID(ip_Test, "setIntentReceiver", "(Ljava/lang/Class;)V");

//_________________________________________________
// Create a new jValue from the IntentRecieverClass
JValue val = new JValue(reciever.Class);

                //______________________________________________________________________________________
// Set the intent reciever by calling the setIntentReciever method passing in the jValue
JNIEnv.CallStaticVoidMethod(ip_class, ip_setIntent, val);

仅供参考，来自java的调用如下所示：PushManager.shared（）.setIntentReceiver（IntentReceiver.class）；
