解决方案

使用插件 cordova-file-Transfer 并进行以下更改： / p>

您可以为Android平台更改插件。

创建类 FileProgressBarTask 与以下代码：

  package org.apache.cordova.filetransfer; 
 
 import android.app.NotificationManager; 
 import android.os.AsyncTask; 
 import android.support.v4.app.NotificationCompat; 
 import android.util.Log; 
 
 class FileProgressBarTask extends AsyncTask< Void，Integer，Integer> {
 
 private NotificationCompat.Builder mBuilder; 
 private NotificationManager mNotificationManager; 
 int id = 0; 
 int progress = 0; 
 
 FileProgressBarTask（NotificationCompat.Builder mBuilder，NotificationManager mNotificationManager，int id）{
 
 Log.d（TAG，Progress Bar）; 
 
 this.mBuilder = mBuilder; 
 this.mNotificationManager = mNotificationManager; 
 this.id = id; 
 
 super.execute（）; 
} 
 
 @Override 
 protected void onPreExecute（）{
 super.onPreExecute（）; 
 
 mBuilder.setProgress（150，0，false）; 
 mNotificationManager.notify（id，mBuilder.build（））; 
} 
 
 @Override 
 protected void onProgressUpdate（Integer ... values）{
 mBuilder.setProgress（150，values [0]，false）; 
 mNotificationManager.notify（id，mBuilder.build（））; 
 super.onProgressUpdate（values）; 
} 
 
 @Override 
 protected Integer doInBackground（Void ... params）{
 return null; 
} 
 
 @Override 
 protected void onPostExecute（Integer result）{
 super.onPostExecute（result）; 
 mBuilder.setContentText（DownloadConcluído）; 
 
 mBuilder.setProgress（0，0，false）; 
 mNotificationManager.notify（id，mBuilder.build（））; 
} 
} 
  

更改类 FileTransfer 与下面的代码：

  import android.content.res.Resources; 
 import android.content.Context; 
 import android.app.NotificationManager; 
 import android.support.v4.app.NotificationCompat; 
 import android.support.v4.app.NotificationCompat.Builder; 
 

在类 FileTransfer ：

 上下文contextApplication = cordova.getActivity（）。getApplicationContext 
资源resources = contextApplication.getResources（）; 
 String pkgName = contextApplication.getPackageName（）; 
 
 int resId = resources.getIdentifier（ic_action_download，drawable，pkgName）; 
 
 mNotificationManager =（NotificationManager）cordova.getActivity（）。getSystemService（Context.NOTIFICATION_SERVICE）; 
 mBuilder = new NotificationCompat.Builder（cordova.getActivity（））; 
 mBuilder.setContentTitle（Download File）
 .setContentText（Progress）
 .setSmallIcon（resId）; 
 
 final FileProgressBarTask progressBarTask = new FileProgressBarTask（mBuilder，mNotificationManager，id）; 
  

查找包含以下内容的方法下载的块代码： while 和 progress.setLoaded（inputStream.getTotalRawBytesRead（））; 在方法下载时，插入以下代码：

  long lng = Math.abs（progress.getLoaded（）/ 100）/ 100）; 
 progressBarTask.onProgressUpdate（Integer.parseInt（String.valueOf（lng）））;

解决方案

Use plugin cordova-file-Transfer and make the following changes:

You can change the plugin this way for android platform.

Create class FileProgressBarTask with bellow code:

package org.apache.cordova.filetransfer;

import android.app.NotificationManager;
import android.os.AsyncTask;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

class FileProgressBarTask extends AsyncTask<Void, Integer, Integer> {

    private NotificationCompat.Builder mBuilder;
    private NotificationManager mNotificationManager;
    int id = 0;
    int progress = 0;

    FileProgressBarTask(NotificationCompat.Builder mBuilder, NotificationManager mNotificationManager, int id){

        Log.d("TAG", "Progress Bar");

        this.mBuilder = mBuilder;
        this.mNotificationManager = mNotificationManager;
        this.id = id;

        super.execute();
    }

    @Override
    protected void onPreExecute(){
        super.onPreExecute();

        mBuilder.setProgress(150, 0, false);
        mNotificationManager.notify(id, mBuilder.build());
    }

    @Override
    protected void onProgressUpdate(Integer... values){
        mBuilder.setProgress(150, values[0], false);
        mNotificationManager.notify(id, mBuilder.build());
        super.onProgressUpdate(values);
    }

    @Override
    protected Integer doInBackground(Void... params) {
        return null;
    }

    @Override
    protected void onPostExecute(Integer result){
        super.onPostExecute(result);
        mBuilder.setContentText("Download Concluído");

        mBuilder.setProgress(0, 0, false);
        mNotificationManager.notify(id, mBuilder.build());
    }
}

Change class FileTransfer with bellow code:

import android.content.res.Resources;
import android.content.Context;
import android.app.NotificationManager;
import android.support.v4.app.NotificationCompat;
import android.support.v4.app.NotificationCompat.Builder;

On the line ~700 in method download on class FileTransfer:

Context contextApplication = cordova.getActivity().getApplicationContext();
Resources resources = contextApplication.getResources();
String pkgName = contextApplication.getPackageName();

int resId = resources.getIdentifier("ic_action_download", "drawable", pkgName);

mNotificationManager = (NotificationManager) cordova.getActivity().getSystemService(Context.NOTIFICATION_SERVICE);
mBuilder = new NotificationCompat.Builder(cordova.getActivity());
mBuilder.setContentTitle("Download File")
        .setContentText("Progress")
        .setSmallIcon(resId);

final FileProgressBarTask progressBarTask = new FileProgressBarTask(mBuilder, mNotificationManager, id);

Find the block code on the method download that contains: while and progress.setLoaded(inputStream.getTotalRawBytesRead()); on method download, insert bellow code:

long lng = Math.abs((progress.getLoaded() / 100) / 100);
progressBarTask.onProgressUpdate(Integer.parseInt(String.valueOf(lng)));
