How to write string to file within broadcast receiver ?

I have set up a Broadcast Receiver to capture current running task. The Class display the task name using Toast but I need to write the String to a file

Is there a way I can write the String to a file within the Broadcast Receiver?

public void onReceive(Context aContext, Intent anIntent) {
    try {

        //TextView  run = (TextView)findViewById(R.id.text1);
        //ArrayList<String> task1 = new ArrayList<String>();

         ActivityManager am = (ActivityManager) aContext
                 .getSystemService(Context.ACTIVITY_SERVICE);
          List<ActivityManager.RunningTaskInfo> alltasks = am
                  .getRunningTasks(1);
          for (ActivityManager.RunningTaskInfo aTask : alltasks) {
              task=aTask.baseActivity.getPackageName();
              //task1.add(task);
             // run.setText(task);

            Toast.makeText(aContext, task , Toast.LENGTH_LONG).show();
              saveTask(aContext,task);
          }

Now I want to write the string task into a file. How to do it within broadcast receiver class?

Following is a simple code to write a text in file. 

File myFile = new File("/sdcard/mysdfile.txt");
myFile.createNewFile();
FileOutputStream fOut = new FileOutputStream(myFile);
OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut);
myOutWriter.append( "Your Text goes here");
myOutWriter.close();
fOut.close();

Also you need to define following permission in AndroidManifest.xml file

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
