自定义cordova插件实现在app内通过URLSCHEM协议打

最近开发的一款移动app应用基于ionic3+ng5+cordova移动框架，需求如下：需要在当前应用中通过urlScheme协议的方式打开本机的另外一个app应用，实现的效果如下：

1.自定义cordvoa插件核心代码如下

public class Printer extends CordovaPlugin {

    private CallbackContext mcallbackContext;

    @Override
    public boolean execute(String action, String rawArgs, CallbackContext callbackContext) throws JSONException {
        return super.execute(action, rawArgs, callbackContext);
    }

    @Override
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
        this.mcallbackContext=callbackContext;
        if (action.equals("openApp")){
            final String url = args.getString(0);
            cordova.getThreadPool().execute(new Runnable() {
                @Override
                public void run() {
                    go("guoxinsdk://?json="+url);

                }
            });

            return true;
        }
        return false;
    }
    @Override
    public boolean execute(String action, CordovaArgs args, CallbackContext callbackContext) throws JSONException {
        return super.execute(action, args, callbackContext);

    }
    private void go(String json){
        PackageManager packageManager = cordova.getActivity().getPackageManager();
        Intent intent = new Intent(Intent.ACTION_VIEW,
                Uri.parse(json));
        List<ResolveInfo> activities = packageManager.queryIntentActivities(intent, 0);
        boolean isValid = !activities.isEmpty();
        if (isValid) {
            cordova.startActivityForResult((CordovaPlugin) this, intent, 1);

            PluginResult pluginResult = new  PluginResult(PluginResult.Status.OK);
            pluginResult.setKeepCallback(true); // Keep callback
        }else{
            Toast.makeText(cordova.getActivity(), "请下载最新版国信影像云", Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
            case 1:
                if(resultCode == RESULT_OK) {
                   // Log.i("aa-------------","+++++++++++++"+data.getStringExtra("siitresult"));
/*                    PluginResult pluginResult = new PluginResult(PluginResult.Status.OK,"中间消息");
                    pluginResult.setKeepCallback(true);
                    mcallbackContext.sendPluginResult(pluginResult);*/
                    try {
                        JSONObject jsonObject=new JSONObject(data.getStringExtra("siitresult"));
                        String result=jsonObject.optString("result");
                        if("2".equals(result)){
                            mcallbackContext.error(data.getStringExtra("siitresult"));
                        }else if("1".equals(result)){
                            mcallbackContext.success(data.getStringExtra("siitresult"));
                        }else {
                           // mcallbackContext.error("未知错误");
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }



                }
                break;
        }
   }
} 

2.plugin.xml配置文件如下

<?xml version='1.0' encoding='utf-8'?>

<plugin xmlns="http://apache.org/cordova/ns/plugins/1.0"
        xmlns:android="http://schemas.android.com/apk/res/android"
        id="cordova-plugin-huiju-printer" 
        version="0.0.1">

  <name>cordova-plugin-huiju-printer</name>

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

  <platform name="android">
    <source-file src="src/android/Printer.java" target-dir="src/com/huiju/cordova/plugins/printer" />
    <config-file parent="/*" target="res/xml/config.xml">
      <feature name="Printer">
        <param name="android-package" value="com.huiju.cordova.plugins.printer.Printer" />
      </feature>
    </config-file>
  </platform>
</plugin>

3.原生抛给前端调用的js如下

var exec = require('cordova/exec');
/**
 * GxyxyURLScheme :是plugin.xml中配置的feature的nema
 * openApp: 是js中调用的方法名
 */
exports.openApp = function(arg0,success,error) {
    exec(success,error, "Printer", "openApp", [arg0]);
};
