科尔多瓦3.4不能使用异步方法。的onSuccess插件方法的第一个电话后不叫 [英] Cannot use asynchronous methods in Cordova 3.4. Onsuccess is not called after the first call of plugin method

问题描述

继code不能正常工作：

Following code does not work properly:

public class TestPlugin extends CordovaPlugin {
   public static CallbackContext callbackContext;

   class TestRun implements Runnable {
      public void run() {
         try {
            Thread.sleep(10000);
         } catch (InterruptedException e) {}

         PluginResult result = new PluginResult(PluginResult.Status.OK, callbackContext.getCallbackId()); 
         result.setKeepCallback(false); 
         callbackContext.sendPluginResult(result); 
      }
   }

   @Override
   public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
      this.callbackContext = callbackContext;
      TestRun tr = new TestRun();
      new Thread(tr).start();
      return true;
   }
}

JS code：

JS code:

var Test = {
   getBTPrinters: function(successCallback, errorCallback) {
      cordova.exec(successCallback, errorCallback, "TestPlugin", "test", []);
      setTimeout(function(){ cordova.exec(successCallback, errorCallback, "TestPlugin", "test", []); }, 30000);
   }
}

回调的onSuccess 时，我打电话从TestPlugin首次的方法我的JavaScript code不叫。结果
当我打电话的方法，从这个插件第二次，然后我得到第一次调用的onSuccess回调。结果
插件的方法的第三个电话后，我获得了第二个电话的onSuccess回调。结果
等等等等。
它是科尔多瓦/ PhoneGap的一个错误？结果
或者，我用我的插件以错误的方式？

Callback onsuccess in my Javascript code is not called when I call a method from TestPlugin for the first time.
When I call method from this plugin for the second time, then I get onsuccess callback from the first call.
After third call of plugin's method I get onsuccess callback from the second call.
And so on and so forth. Is it a bug of Cordova/Phonegap?
Or I use my plugin in a wrong way?

推荐答案

不断地调用exec将强制进程的消息。

Constantly calling exec will force process the messages.

setInterval(function () {
    cordova.exec(null, null, '', '', [])
}, 200);
