在 Ionic 中检索和显示来自原生 Cordova 插件的值

Question

我正在尝试从我在 Cordova 中构建的本机 SDK 插件中检索标识号，但无论我尝试什么我都看不到它。我有一个本机 Android 应用程序可以从设备获取号码，但代码不会直接转换为 Cordova。

工作Android代码：

    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Device = SdkForAndroid.getInstance(this);

    // First, we test if the device was already initialized. 
    if (!Device.isInitialized()) {

        Log.i(TAG, "mobile device not initialized yet");

        initializeSDK();

    } else {

        // if we already initialized, show the Secured Objects we got

        //Log.i(TAG, "device is initialized. deviceId: " + mobileDevice.getDeviceId());
        TextView textView = (TextView) findViewById(R.id.txtDeviceId);
        textView.setText("" + Device.getDeviceId());
    }
}

Private void initializeSDK() {
    new Thread() {

        @Override
        public void run() {
            try {
                String deviceId = Device.initialize();//hidden sdk code

                Log.i(TAG, "initialized SDK, deviceId = " + deviceId);
            } catch (Exception e) {
                Log.e(TAG, "failed to initialize SDK", e);
            } 
        }
    }.start();
}

科尔多瓦代码：

public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
    this.callbackContext = callbackContext;
    if (action.equals("initializeSDK")) {
        cordova.getActivity().runOnUiThread(
            new Runnable() {
                public void run() {
                        isInitialized();
                    }
                });
            return true;
        }
protected void isInitialized(){
                  Device = SdkForAndroid.getInstance(cordova.getActivity());
                  try{
                        if (!Device.isInitialized()) {
                            Log.i(TAG, "mobile device not initialized yet");
                            initSDK();
                        } else {
                            Log.i(TAG, "mobile device is initialized. deviceId: " + Device.getDeviceId());
                        }
                        this.callbackContext.success(mobileDevice.getDeviceId());
                  } catch (Exception e){
                        this.callbackContext.error("Error");
                  }

}

protected void initSDK(){
    cordova.getThreadPool().execute(new Runnable() {
        public void run() {
                    try{
                        String deviceId = mobileDevice.initialize()
                            //hidden sdk code
                        Log.i(TAG, "initialized SDK, deviceId = " + deviceId);
                                callbackContext.success(deviceId);
                            } catch (Exception e){
                                Log.e(TAG, "failed to initialize SDK", e);
                                callbackContext.error("Error");
                            }
                }
            });
}

Javascript代码：

var exec = require('cordova/exec');

module.exports = {
    initializeSDK: function (success, fail) {
        cordova.exec(success, fail, 'BlueIDplugin', 'initializeSDK', []);
    }
};

离子appcomponent.ts

 initiateSDK(){

    this.BlueIdPlugin.initializeSDK(
      function(success){
        console.log(deviceId);
      },
      function(fail){
        console.log("Error getting device id")
      }
    )

    this.BlueIdPlugin.initializeSDK();
    console.log(this.BlueIdPlugin.getDeviceId());
  }

我认为我正确地链接了代码，因为 SDK 是用我的控制台日志初始化的。问题是我无法显示 deviceId。我真的不确定如何与 ionic 本身的问题进行交互，我相信问题确实存在，因为我没有正确调用成功回调。请帮忙！ :(

似乎你调用了两次成功回调，即使设备没有初始化：

this.callbackContext.success(mobileDevice.getDeviceId());

这会导致 callbackContext 被调用两次，这是 Cordova 不允许的（除非您明确请求）。所以试试这个：

科尔多瓦代码：

public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
    this.callbackContext = callbackContext;
    if (action.equals("initializeSDK")) {
        cordova.getActivity().runOnUiThread(
            new Runnable() {
                public void run() {
                        isInitialized();
                    }
                });
            return true;
        }
protected void isInitialized(){
    Device = SdkForAndroid.getInstance(cordova.getActivity());
    try{
        if (!Device.isInitialized()) {
            Log.i(TAG, "mobile device not initialized yet");
            initSDK();
        } else {
            Log.i(TAG, "mobile device is initialized. deviceId: " + Device.getDeviceId());
            this.callbackContext.success(Device.getDeviceId());
        }
    } catch (Exception e){
        this.callbackContext.error("Error");
    }

}

protected void initSDK(){
    cordova.getThreadPool().execute(new Runnable() {
        public void run() {
                try{
                    String deviceId = mobileDevice.initialize()
                        //hidden sdk code
                    Log.i(TAG, "initialized SDK, deviceId = " + deviceId);
                    callbackContext.success(deviceId);
                } catch (Exception e){
                    Log.e(TAG, "failed to initialize SDK", e);
                    callbackContext.error("Error");
                }
        }
    });
}

appcomponent.ts:

initiateSDK(){
    this.BlueIdPlugin.initializeSDK(
      function(success){
        console.log(deviceId);
      },
      function(fail){
        console.log("Error getting device id")
      }
    )
}

Answer 2

原来问题出在我的插件顶部的包名上。它最后有一个额外的文件夹目录，所以插件实际上并没有连接到 Ionic 应用程序。

所以本质上

   <feature name="IDplugin">
        <param name="android-package" value="IdCordovaPlugin.IDplugin"/>
   </feature>

必须与 Cordova java 插件顶部的包名称相匹配

package IdCordovaPlugin;

我犯了一个非常愚蠢的错误，后来通过 logcat 调试发现。
