Authorization: Bearer eyJ0eXA

Answer 1

According to the documentation here

  private final OkHttpClient client = new OkHttpClient();
  private final String url = "http://test.com";

  public void run(String token) throws Exception {
    Request request = new Request.Builder()
    .url(url)
    //This adds the token to the header.
    .addHeader("Authorization", "Bearer " + token)
    .build();
     try (Response response = client.newCall(request).execute()) {
          if (!response.isSuccessful()){
             throw new IOException("Unexpected code " + response);
          }

         System.out.println("Server: " + response.header("anykey"));

     }
  }

Answer 2

The above answer lead to correct path but need some changes.

private  Response requestBuilderWithBearerToken(String userToken) throws IOException {
           OkHttpClient client = new OkHttpClient();
           Request request = new Request.Builder()
                   .url(YourURL)
                   .get()
                   .addHeader("cache-control", "no-cache")
                   .addHeader("Authorization" , "Bearer " + userToken)
                   .build();

           return  client.newCall(request).execute();

For android Okhttp Version

public Call post(String url, String json, Callback callback, String token) {
    OkHttpClient client = new OkHttpClient();

    RequestBody body = RequestBody.create(JSON, json);
    Request request = new Request.Builder()
        .url(url)
        .addHeader("Authorization", "Bearer " + token)
        .post(body)
        .build();
    Call call = client.newCall(request);
        call.enqueue(callback);
    return call;
}

remember to put space after Bearer keyword.
