android - Ionic build cannot find module 错误。如何导入安卓插件？

Question

我正在尝试开发一个用于 Ionic 应用程序的 Android 插件。

我使用 Ionic 使用 ionic start myApp tabs 提供的入门项目创建了应用程序。

我还在另一个文件夹中创建了我的插件，其中包含以下文件。

plugin.xml

<?xml version="1.0" encoding="UTF-8"?>
<plugin xmlns="http://apache.org/cordova/ns/plugins/1.0"
    id="location-plugin" version="0.0.1">
<name>GSLocationManager</name>
<description>Location Plugin</description>
<license>MIT</license>
<keywords>cordova,device,sensors,location</keywords>

<js-module name="LocationManager" src="www/LocationManager.js">
    <clobbers target="LocationManager" />
</js-module>

<engines>
    <engine name="cordova" version=">=3.6.0"></engine>
</engines>

<platform name="android">
  <preference name="GOOGLE_PLAY_SERVICES_VERSION" default="11+"/>
  <preference name="ANDROID_SUPPORT_LIBRARY_VERSION" default="26+"/>
  <preference name="ICON" default="@mipmap/icon" />
  <preference name="SMALL_ICON" default="@mipmap/icon" />
  <preference name="ACCOUNT_NAME" default="@string/app_name" />
  <preference name="ACCOUNT_LABEL" default="@string/app_name" />
  <preference name="ACCOUNT_TYPE" default="$PACKAGE_NAME.account" />
  <preference name="CONTENT_AUTHORITY" default="$PACKAGE_NAME" />

  <framework src="com.google.android.gms:play-services-location:$GOOGLE_PLAY_SERVICES_VERSION" />
  <framework src="com.android.support:support-v4:$ANDROID_SUPPORT_LIBRARY_VERSION" />
  <framework src="com.android.support:appcompat-v7:$ANDROID_SUPPORT_LIBRARY_VERSION" />
  <!-- <framework src="android/dependencies.gradle" custom="true" type="gradleReference"/> -->

  <source-file src="path/to/locationmanager/GSLocationManager.java"
               target-dir="path/to/locationmanager"></source-file>

  <config-file target="AndroidManifest.xml" parent="/manifest">
     <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />
     <uses-permission android:name="android.permission.READ_SYNC_SETTINGS" />
     <uses-permission android:name="android.permission.WRITE_SYNC_SETTINGS" />
     <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
     <uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION" />
     <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
     <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
     <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
     <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
     <uses-permission android:name="android.permission.INTERNET" />
     <uses-permission android:name="android.permission.WAKE_LOCK" />
     <uses-permission android:name="android.hardware.location" />
  </config-file>

  <config-file target="res/xml/config.xml" parent="/*">
      <feature name="GSLocationManager">
          <param name="android-package" value="android.package.locationmanager.GSLocationManager" />
      </feature>
  </config-file>
</platform>

locationManager.js

var GSLocationManager = {
  getCurrentLocation: function(success, failure) {
    exec(success, failure, 'GSLocationManager', 'getCurrentLocation', []);
  }
}

module.exports = GSLocationManager;

GSLocationManager.java

package android.package.locationmanager;

import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaInterface;
import org.apache.cordova.CordovaWebView;
import org.apache.cordova.CordovaPlugin;

import org.json.JSONArray;
import org.json.JSONObject;
import org.json.JSONException;

import android.annotation.SuppressLint;
import android.content.Context;
import android.location.Location;
import android.location.LocationManager;

public class GSLocationManager extends CordovaPlugin {

    private JSONObject data = new JSONObject();

    // at the initialize function, we can configure the tools we want to use later, like the sensors
    @Override
    public void initialize(CordovaInterface cordova, CordovaWebView webView) {
        super.initialize(cordova, webView);

    }

    // safety unregistering from the events if the application stops somehow
    @Override
    public void onDestroy() {

    }

    // this is the main part of the plugin, we have to handle all of the actions sent from the js
    @Override
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
        if ("getCurrentLocation".equals(action)) {
            Location location = getCurrentLocation();
            JSONObject json = new JSONObject();
            json.put("latitude", location.getLatitude());
            json.put("longitude", location.getLongitude());
            callbackContext.success(json);
            return true;
        }
        return false;  // Returning false results in a "MethodNotFound" error.
    }

    @SuppressLint("MissingPermission")
    private Location getCurrentLocation() {
        LocationManager locationManager = (LocationManager) cordova.getActivity().getApplicationContext().getSystemService(Context.LOCATION_SERVICE);

        Location lastKnownGPSLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        return lastKnownGPSLocation;
    }
}

然后我为我的插件使用 plugman 创建了一个 package.json 之后，将我的 android 插件添加到我的 Ionic 项目中 ionic cordova 插件添加路径/to/my/plugin

但我似乎无法使用 import { GSLocationManager } from 'globespinning-location-plugin' 将我的插件导入到 app.module.ts 我尝试构建，但 CLI 显示 ERROR in src/app/app.module.ts(12,31): error TS2307: Cannot find module 'globespinning-location-plugin'./p>

知道错误在哪里吗？ 我应该如何导入由我创建并从本地文件夹引用的插件？ 我希望能够在我的 ionic 应用程序中调用 GSLocationManager.getCurrentLocation()。

你想继续运行 ionic cordova plugin add "folder path of your custom plugin" 然后在 .ts 文件中你想使用它想要声明如下，declare var myPlugin: any;

声明插件后，您可以继续使用它，如下所示:

myPlugin.myFuntion((data) => {
        console.log(data);
},(err) => {
        console.log(err);
});

因此在您的情况下，您将使用以下内容:

declare var GSLocationManager: any;

....

GSLocationManager.getCurrentLocation().then((data) => {});
