I have an image contents byte[] form. But when i load them through Glide then broken images are shown. what I'm doing is shown below.
Glide.with(context)
.load(imageByteArray)
.asBitmap()
.placeholder(R.drawable.ic_broken)
.into(rowImageView);
imageByteArray successfully converts to bitmap without using glide. So there is no wrong with image byte array.
Please guide me what I'm missing?
Also I'm using Glide library com.github.bumptech.glide:glide:3.6.1 And Android support library com.android.support:support-v13:23.0.1

Ok, This is what I'm doing.
String imageBytes = "HVao14fpmtHSev3OgsrQNsawkFzXNcY3BsfQla6..."
This string above defined is bytes of actual image which I'm receiving from web API.
I'm converting this String into byte array like this
public static byte[] hexStringToByteArray(String s) {
int len = s.length();
byte[] data = new byte[len / 2];
for (int i = 0; i < len; i += 2) {
data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
+ Character.digit(s.charAt(i+1), 16));
}
return data;
}
Than I'm applying resultant byte array "imageByteArray" to Glide code defined above.

Lets say your base64 string is
String imageBytes = "HVao14fpmtHSev3OgsrQNsawkFzXNcY3BsfQla6..."
You should convert imageBytes String to array of bytes through
byte[] imageByteArray = Base64.decode(imageBytes, Base64.DEFAULT);
afterwards pass this imageByteArray to Glide.
Glide.with(context)
.load(imageByteArray)
.asBitmap()
.placeholder(R.drawable.ic_broken)
.into(rowImageView);
You can convert Base64 String to image using the following
Glide.with(context)
.load(Base64.decode(base64ImageString, Base64.DEFAULT))
.asBitmap()
.placeholder(R.drawable.ic_broken)
.into(rowImageView);
If you are getting error on .asBitmap() just use it like this
Glide.with(this)
.asBitmap()
.load(imageAsBytes)
.into(image)
Kotlin way:
val imageByteArray = Base64.decode(sampleBase64ImageString, Base64.DEFAULT)
Glide.with(this).load(imageByteArray).into(imageView)
I do it a bit differently
byte[] bytes = Glide.with(context)
.as(byte[].class)
.load(url)
.submit()
.get();
The bytes are ready for file writing.
