Picasso disk cache not working

Question

I use picasso to download and cache image but the images does't cache but download successfully and i don't fin the problem and i use dagger to decency inject picasso object also but i don't think that is the problem

Here is my code at the adapter as i pass picasso to the adapter object

    picasso.load(currentClient.getLogoUrl())
            .placeholder(R.mipmap.ic_launcher)
            .into(holder.clientImage);

And my di code

@Module(includes = {ContextModule.class, NetworkModule.class})
public class PicassoModule {

    @Provides
    @InmaaApplicationScope
    public Picasso picasso(@ApplicationContext Context context, OkHttp3Downloader okHttp3Downloader) {
        return new Picasso.Builder(context)
                .downloader(okHttp3Downloader)
                .build();
    }

    @Provides
    @InmaaApplicationScope
    public OkHttp3Downloader okHttp3Downloader(OkHttpClient okHttpClient) {
        return new OkHttp3Downloader(okHttpClient);
    }
}

The other module

@Module(includes = ContextModule.class)
public class NetworkModule {

    @Provides
    @InmaaApplicationScope
    public HttpLoggingInterceptor loggingInterceptor() {
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor(message -> Timber.i(message));
        interceptor.setLevel(HttpLoggingInterceptor.Level.BASIC);
        return interceptor;
    }

    @Provides
    @InmaaApplicationScope
    public Cache cache(File cacheFile) {
        return new Cache(cacheFile, 512 * 1024 * 1024); //512 MB for cache
    }

    @Provides
    @InmaaApplicationScope
    public File cacheFile(@ApplicationContext Context context) {
        return new File(context.getCacheDir(), "okhttp_cache");
    }

    @Provides
    @InmaaApplicationScope
    public OkHttpClient okHttpClient(HttpLoggingInterceptor loggingInterceptor, Cache cache) {
        return new OkHttpClient.Builder()
                .addInterceptor(loggingInterceptor)
                .cache(cache)
                .build();
    }

}

at the Activity code

  @Inject
    Picasso picasso;

        clientsAdapter = new ClientsAdapter(picasso);

The state of the cache folder

~~I think you forgot to actually set the Picasso instance:~~

Picasso.setSingletonInstance(/* insert your instance here*/));

This has to be done before you load any image with Picasso.

Since you are using your own Picasso instance I guess the images don't have proper caching headers. See the comments below.
