Android: Create a file from a Service

Question

I have been successfully able to create files in my apps local directory using the below code

    File appDir = new File(this.getExternalFilesDir(null), "my_folder");
    if (!appDir.exists())
    {
        boolean result = appDir.mkdir();
        if (!result) {
            Log.i(Util.TAG, LOG_LABEL
                    + "::  Unable to create \"my_folder\" Directory : "
                    + appDir.getAbsolutePath()
                    + "  Directory already exists !");
        }
    }


    File HTMLFile = new File(appDir,"html.txt");

But now when I tried to do the same from a service, the file was not being created, I even checked using 'HTMLFile.exists()' and it says the file does not exist.

My question is, Is it actually possible to create files from a service? or am I missing something here.

Are you passing your activity context to your service? And then using `context.getExternalFilesDir`? — Arkadiusz 'flies' Rzadkowolski, Jul 16 '13 at 06:48
@filespl: Do we need to pass context to the service? I read that Service has its own context. source: http://stackoverflow.com/questions/6446221/get-context-in-a-service — Code_Yoga, Jul 16 '13 at 06:59
I doubt into my answer now :) I thought this could be related to different permissions on the file (or different dir being returned). — Arkadiusz 'flies' Rzadkowolski, Jul 16 '13 at 07:22
@filespl: I was able to create a file now using HTMLFile.createNewFile(); I dindn't have to do this previously though. — Code_Yoga, Jul 16 '13 at 09:46

It is possible to write to the storage of your android: by the help of the following methods

Make sure you provide uses permission to write and read from storage in manifest file.

I have used this code:

private File newFile;

public ListenNotification() {
        Log.d("Service","InConstrutor");
newFile=newFile(Environment.getExternalStorageDirectory(),"NotificationFromService");

        if(!newFile.exists()){
            Log.d("Service","Created");
            newFile.mkdir();
        }
        else{
            Log.d("Service","Existed");
        }
    }
File HTMLFile = new File(newFile,"html.txt");
