Reference:

Convert base64 image data to an image file(.png) and save it to Local file system

Methods a

String base64Img = "";
// If "data:image/jpeg; Base64," prefix, just take the following part
if (base64Img.contains(",")) {
    String[] base64ImgArray = base64Img.split(",");
    if (base64ImgArray.length == 2) {
        base64Img = base64ImgArray[1]; }}/ / decoding
try {
    byte[] decodedString = Base64.decode(base64Img, Base64.DEFAULT);
    Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
    if(mBitmapCreateListener ! =null) { mBitmapCreateListener.onBitmapCreate(decodedByte); }}catch (Exception e) {
    e.printStackTrace();
    // The callback failed to generate the image
    if(mBitmapCreateListener ! =null) {
        mBitmapCreateListener.onBitmapCreate(null); }}Copy the code
