Get OkHttpClient which ignores all SSL errors.

GagSsl.java

  private static OkHttpClient getUnsafeOkHttpClient() {
    try {
      // Create a trust manager that does not validate certificate chains
      final TrustManager[] trustAllCerts = new TrustManager[] {
          new X509TrustManager() {
            @Override
            public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
            }

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

            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
              return null;
            }
          }
      };

      // Install the all-trusting trust manager
      final SSLContext sslContext = SSLContext.getInstance("SSL");
      sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
      // Create an ssl socket factory with our all-trusting manager
      final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

      OkHttpClient okHttpClient = new OkHttpClient();
      okHttpClient.setSslSocketFactory(sslSocketFactory);
      okHttpClient.setHostnameVerifier(new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
          return true;
        }
      });

      return okHttpClient;
    } catch (Exception e) {
      throw new RuntimeException(e);
    }
  }

I have this error.

java.lang.RuntimeException: java.lang.IllegalStateException: trustManager.acceptedIssuers must not be null
at com.example.advertiseapp.API_Package.RetrofitClientBase.getUnsafeOkHttpClient(RetrofitClientBase.java:103)
...

Replace
@Override public java.security.cert.X509Certificate[] getAcceptedIssuers() { return null; }

With
@Override public java.security.cert.X509Certificate[] getAcceptedIssuers() { return new java.security.cert.X509Certificate[]{}; }

Hi @chalup Can u license your code to Apache 2.0 same as okhttp library?
