What could be alternative without need to keep context?

In a class which is not Activity and thus doesn't have a Context I need to store a file like:

public static void saveAvatar(String fileName, Bitmap avatar) {
    if (avatar == null)
        return;

    FileOutputStream fos;
    try {
        fos = context.openFileOutput(fileName + ".jpg", Context.MODE_PRIVATE);
        avatar.compress(Bitmap.CompressFormat.JPEG, 100, fos);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
}

To make it work I need to keep a context in a class because I'm calling this method from another class which doesn't have a context either. Is there a way to do it without context like using ContentResolver or something like?

You can use the Context of your application class. Use the following template to be able to use your application class as a singleton:

private static MyApplication instance;

public static MyApplication getInstance() {
  return instance;
}

@Override
public void onCreate() {
  super.onCreate();
  instance = this;
}

Now, you can change your code to the following:

public static void saveAvatar(String fileName, Bitmap avatar) {
    if (avatar == null)
        return;

    FileOutputStream fos;
    try {
        fos = MyApplication.getInstance().openFileOutput(fileName + ".jpg", Context.MODE_PRIVATE);
        avatar.compress(Bitmap.CompressFormat.JPEG, 100, fos);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
}

A couple of ways.

1)Pass in a context in the constructor

2)Pass in the file or the directory in the constructor and just create the file using the standard java apis.
