Android application crashes after starting it second or third time (Showing memory error)-Collection of common programming errors

I am working on application which uses downloaded images from my application to display in the background. When I start application it works fine and load image without any problem. But after several restart application crashes with memory error. I use below method for get Drawable to show it in View. I have used one class and which having this static method I use it for all images. I also call one other static method for clear bitmap but don’t know it works or not. May be I do not able to clear memory when I close application.

    public static void recycle_bitmap() {
    if (myBitmap != null) {
        myBitmap.recycle();
        myBitmap = null;

    }

    }

    static Bitmap myBitmap = null;

    public static Drawable ImgDrawableFromFile(Resources res, String file_name) {

    myBitmap=null;
    File imgFile = new File("/data/data/com.appstart/app_my_sub_dir/"
            + file_name + ".jpg");
    if (imgFile.exists()) {

        myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
        if (myBitmap != null)
            return new BitmapDrawable(res, myBitmap);
        else
            return null;
    }
    return null;

    }
