Create / write files on Pepper QISDK

We want to take a picture on a Pepper Robot and save it (somehow) -> The first idea is to compress to .jpg file.
TakePicture action is taken from QISDK tutorial, then we create the File as given below:


    File file = new File("image.jpg");
    try {
        file.createNewFile();
    } catch (IOException e) {
        e.printStackTrace();
    }
    try {
        FileOutputStream out = new FileOutputStream(file);
        getPicture().compress(Bitmap.CompressFormat.JPEG, 100, out); 
    // getPicture() is The Bitmap we get from TakePicture Action.
        Log.i("COMPRESSED", "SUCCES");
        out.close();
    } catch (IOException e) {
        Log.i("COMPRESSED", "FAIL");
        e.printStackTrace();
    }

But the code throws exception IOException Read-only file system. That means, that the Robot environment prevents from creating/writing files, which I believe is for the safety reasons. But the picture in Bitmap format is not what we want.
Is there any possible work-around or solutions to this problem?

I have found a solution, I just made a file with 


        file = File.createTempFile("image", ".jpg", this.getCacheDir());

This way it allows to make a fully writable temporary file, that can afterward be compressed, edited etc.
Using absolute path to the /temp android folder might also work, but that depends on Android version.
