This solution with Retrofit

public static final String ACCOUNT_SID = "accountSId";
public static final String AUTH_TOKEN = "authToken";

private void sendMessage() {
    String body = "Hello test";
    String from = "+...";
    String to = "+...";

    String base64EncodedCredentials = "Basic " + Base64.encodeToString(
            (ACCOUNT_SID + ":" + AUTH_TOKEN).getBytes(), Base64.NO_WRAP
    );

    Map data = new HashMap<>();
    data.put("From", from);
    data.put("To", to);
    data.put("Body", body);

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("https://api.twilio.com/2010-04-01/")
            .build();
    TwilioApi api = retrofit.create(TwilioApi.class);

    api.sendMessage(ACCOUNT_SID, base64EncodedCredentials, data).enqueue(new Callback() {
        @Override
        public void onResponse(Call call, Response response) {
            if (response.isSuccessful()) Log.d("TAG", "onResponse->success");
            else Log.d("TAG", "onResponse->failure");
        }

        @Override
        public void onFailure(Call call, Throwable t) {
            Log.d("TAG", "onFailure");
        }
    });
}

interface TwilioApi {
    @FormUrlEncoded
    @POST("Accounts/{ACCOUNT_SID}/SMS/Messages")
    Call sendMessage(
            @Path("ACCOUNT_SID") String accountSId,
            @Header("Authorization") String signature,
            @FieldMap Map metadata
    );
}
