如何将base64字符串转换为blob？

Question

A Synchronization service that provide an image in Base64 string and I want to save that into a SQLite database blob field?

Could anyone tell me how to proceed with this or any other way to do this procedure?

As later on, I need to show image in bitmap.

Answer 1

You convert a base64 image string to byte[] like :

byte[] decodedByte = Base64.decode(yourBase64String, 0); 

after that you also can convert it to Bitmap :

Bitmap bitmap = BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length);

Answer 2

To convert a base64 string to a byte[], you can use:

byte[] decodedByte = Base64.decode(yourBase64String)

And to convert a byte[] to a blob, you can use:

Blob b = new SerialBlob(decodedByte);
