Glide: Load From XmlRPC Base64 String format

[SpiralDeveloper]

Glide Version: 4.3.1

Integration libraries: com.github.piasy:GlideImageLoader

Device/Android Version: Various devices and Android versions.

Issue details / Repro steps / Use case background:

Glide load line / GlideModule (if any) / list Adapter code (if any):

Glide.with...

Layout XML:

<FrameLayout xmlns:android="...

Stack trace / LogCat:

....

I'm using odoo web api here:
https://www.odoo.com/documentation/8.0/api_integration.html

Which returns image in base64 string fomat.
I maintain decent class to handle authentication and parse response to json and finally get image field as base64. Please help I willing to using glide in such case.

Please help this is more likely request than glide issue. Thanks

You can write a custom ModelLoader that obtains the base64 string and decodes it into a byte[].

For more details on how to register custom components see http://bumptech.github.io/glide/doc/configuration.html#registering-components.

For an example ModelLoader, see any of those in Glide, ByteArrayLoader is one simple example.

[SpiralDeveloper]

can you give me sample example. I googled 'ModelLoader' all reference is outdated based on StreamModelLoader.

model

public class ImageRequest {

    public long id;
    public String model;
    public String url;
    public String name;


public static String getBase64(){
    return ...
 }

 public static byte[] getBytes(){
    return ...
  }

 }

Loader

public  class MImageLoader implements ModelLoader<ImageRequest,byte[]> {


@Nullable
@Override
public LoadData<byte[]> buildLoadData(ImageRequest imageRequest, int width, int height, Options options) {
    return null;
}

  @Override
public boolean handles(OdooImageRequest odooImageRequest) {
    return false;
     }
 }

so far this is my initial setup.. How do I process ImageRequest object and return fetched data.

Thanks for brilliant explanation. Thank you for everything you have done.
Seriously, you saved my day. Only one very minor doubt. am I generating key correctly?

*Here is my Model *

 public class OdooBinary {
   public long id;
   public String model;
   public String column;


  private Self self;
  public OdooBinary(Self self, long id, String model, String column){
    this.self=self;
    this.id=id;
    this.model=model;
    this.column=column;
  }

public static OdooBinary dump(Self self, long id, String model, String column){
   return new OdooBinary( self,  id,  model,  column);
}

public Key diskCacheKey(){
    /*
    The combination of these is unique
     */
    return new ObjectKey(model+"_"+id+"_"+column);   //eg.   "res.partner"+"_"+50+"_"+"image_medium"
}
public String getBase64Image() throws XMLRPCException, AccessDeniedException, NetworkException, InvalidLoginException, OdooDatabaseException {
    Mapper mapper=self.env(model).read(id,column);
    return mapper.toString(column);
  }
}

`

Thank you, you are awesome.

Glad it was helpful. It should work, you can avoid the string allocation by implementing Key in OdooBinary, but that's not a big deal, especially if your users are most on ART devices (5.0+).
