Doesn't Picasso support to download images which uses https protocol

Question

Hello I am using the Picasso library to download the images from URL.

URL : https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn2/t1.0-1/s200x200/1472865_191408954385576_14109897_n.jpg

URL is using https protocol, here it is not working for me to download the images of https protocol using Picasso.

Doesn't it support to download the images which uses https protocol, it worked for me only if I use http proctocol ?

Here I am trying to get bitmap which is using https protocol

com.squareup.picasso.Target target = new com.squareup.picasso.Target() {

@Override
public void onBitmapLoaded(Bitmap bitmap, LoadedFrom loadedFrom) {
    userProfile.setBitmap(bitmap);
    // call the Web API to register the walker here
    new AudioStreetAsyncTask(getActivity(), userProfile, getString(R.string.registration_processing_message), new TaskCompleteListener() {
        @Override
        public void onTaskCompleted(String jsonResponse) {
           Log.d(TAG, jsonResponse);
        }
    });
}

@Override
public void onBitmapFailed(Drawable drawable) {
    userProfile.setBitmap(null);
    // call the Web API to register the walker here
    new AudioStreetAsyncTask(getActivity(), userProfile, getString(R.string.registration_processing_message), new TaskCompleteListener() {
        @Override
        public void onTaskCompleted(String jsonResponse) {
           Log.d(TAG, jsonResponse);
        }
    }).execute();
}

@Override
public void onPrepareLoad(Drawable drawable) {}
};

Picasso.with(getActivity()).load(imgUrl.toString()).into(target);

Any idea ?

Answer 1

Use those dependencies in your Gradle:

compile 'com.squareup.okhttp:okhttp:2.2.0'
compile 'com.squareup.okhttp:okhttp-urlconnection:2.2.0'
compile 'com.squareup.picasso:picasso:2.4.0'

And this class instead of the original Picasso class

Picasso class:

 public class PicassoTrustAll {

    private static Picasso mInstance = null;

    private PicassoTrustAll(Context context) {
        OkHttpClient client = new OkHttpClient();
        client.setHostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        });
        TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
            @Override
            public void checkClientTrusted(
                    java.security.cert.X509Certificate[] x509Certificates,
                    String s) throws java.security.cert.CertificateException {
            }

            @Override
            public void checkServerTrusted(
                    java.security.cert.X509Certificate[] x509Certificates,
                    String s) throws java.security.cert.CertificateException {
            }

            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return new java.security.cert.X509Certificate[] {};
            }
        } };
        try {
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            client.setSslSocketFactory(sc.getSocketFactory());
        } catch (Exception e) {
            e.printStackTrace();
        }

        mInstance = new Picasso.Builder(context)
                .downloader(new OkHttpDownloader(client))
                .listener(new Picasso.Listener() {
                    @Override
                    public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
                        Log.e("PICASSO", exception);
                    }
                }).build();

    }

    public static Picasso getInstance(Context context) {
        if (mInstance == null) {
             new PicassoTrustAll(context);
        }
        return mInstance;
    }
}

Usage example:

PicassoTrustAll.getInstance(context)
                .load(url)
                .into(imageView);

@nexus700120 solution is not up to date

@Neha Tyagi solution works but creates multiple instances of Picasso in each instance of activity which leaks memory

So I crafted a up to date and singleton solution for redirecting image URLs -

CustomPicasso.java

import android.content.Context;
import android.util.Log;

import com.jakewharton.picasso.OkHttp3Downloader;
import com.squareup.picasso.Picasso;

/**
 * Created by Hrishikesh Kadam on 19/12/2017
 */

public class CustomPicasso {

    private static String LOG_TAG = CustomPicasso.class.getSimpleName();
    private static boolean hasCustomPicassoSingletonInstanceSet;

    public static Picasso with(Context context) {

        if (hasCustomPicassoSingletonInstanceSet)
            return Picasso.with(context);

        try {
            Picasso.setSingletonInstance(null);
        } catch (IllegalStateException e) {
            Log.w(LOG_TAG, "-> Default singleton instance already present" +
                    " so CustomPicasso singleton cannot be set. Use CustomPicasso.getNewInstance() now.");
            return Picasso.with(context);
        }

        Picasso picasso = new Picasso.Builder(context).
                downloader(new OkHttp3Downloader(context))
                .build();

        Picasso.setSingletonInstance(picasso);
        Log.w(LOG_TAG, "-> CustomPicasso singleton set to Picasso singleton." +
                " In case if you need Picasso singleton in future then use Picasso.Builder()");
        hasCustomPicassoSingletonInstanceSet = true;

        return picasso;
    }

    public static Picasso getNewInstance(Context context) {

        Log.w(LOG_TAG, "-> Do not forget to call customPicasso.shutdown()" +
                " to avoid memory leak");

        return new Picasso.Builder(context).
                downloader(new OkHttp3Downloader(context))
                .build();
    }
}

build.gradle (Module:app)

android {

    ...

}

dependencies {

    ...

    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.jakewharton.picasso:picasso2-okhttp3-downloader:1.1.0'
}

Usage -

CustomPicasso.with(context)
    .load("http://i.imgur.com/DvpvklR.png")
    .into(imageView);

 final OkHttpClient client = new OkHttpClient.Builder()
                    .protocols(Collections.singletonList(Protocol.HTTP_1_1))
                    .build();

            Picasso picasso = new Picasso.Builder(mContext)
                    .downloader(new OkHttp3Downloader(client))
                    .build();
picasso .with(mContext).load(YOUR_URL).into(YOUR_IMAGEVIEW);

Add

compile 'com.jakewharton.picasso:picasso2-okhttp3-downloader:1.1.0'
