How Can I Store Jpegs As Byte[] For Faster Loading?

I need to load ~150 JPEG images into ArrayList for playing an animation. If I load them like that ByteArrayOutputStream stream = new ByteArrayOutputStream(); BitmapFactory.decodeR

Solution 1:

You can use the method below to get the raw data from a resource. You don't need to decode then compress again.

byte[] getBytesFromResource(final int res) {
    byte[] buffer = null;
    InputStream input = null;

    try {
        input = getResources().openRawResource(res);
        buffer = new byte[input.available()];
        if (input.read(buffer, 0, buffer.length) != buffer.length) {
            buffer = null;
        }
    } catch (IOException e) {
        buffer = null;
    } finally {
        if (input != null) {
            try {
                input.close();
            } catch (IOException e) {}
        }
    }

    return buffer;
}
