Salesforce MobileSDK: The Rest API is not enabled for this Organization

Question

I am trying to use Salesforce Mobile SDK for native Android. Requirement:

1. Allow any user with Salesforce account to login
2. Fetch his/her contacts list
3. Fetch particular contact details

Please let me know if those are not part of the Mobile SDK.

I followed https://github.com/forcedotcom/SalesforceMobileSDK-Android:

1. Cloned it
2. Installed NPM and installed the required submodules
3. Created a new Android application using native forcedroid
4. Changed the bootconfig.xml values with the values of my connected app.

It logs in fine but when I try to fetch the contacts, it says:

The Rest API is not enabled for this Organization

The login response seems to be fine. Client object json credentials:

{
  "clientId": "*******",
  "loginUrl": "https://login.salesforce.com",
  "identityUrl": "https://login.salesforce.com/id/99VVHJHGF5688/00548000003yOKeAAM",
  "instanceUrl": "https://ap2.salesforce.com",
  "userId": "**********",
  "orgId": "*********",
  "communityUrl": null,
  "refreshToken": "*************",
  "accessToken": "************",
  "communityId": null,
  "userAgent": "SalesforceMobileSDK/4.3.0 android mobile/7.0 (Nexus 6P) SFTest/1.0 Native uid_32aea9bdde1b8b7e"
}

EDIT 1 : Code to get Contacts list:

public void onFetchContactsClick(View v) throws UnsupportedEncodingException {
    sendRequest("SELECT Name FROM Contact");
}

private void sendRequest(String soql) throws UnsupportedEncodingException {
    RestRequest restRequest = RestRequest.getRequestForQuery(ApiVersionStrings.getVersionNumber(this), soql);

    client.sendAsync(restRequest, new AsyncRequestCallback() {
        @Override
        public void onSuccess(RestRequest request, final RestResponse result) {
            result.consumeQuietly(); // consume before going back to main thread
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    try {
                        listAdapter.clear();
                        JSONArray records = result.asJSONObject().getJSONArray("records");
                        for (int i = 0; i < records.length(); i++) {
                            listAdapter.add(records.getJSONObject(i).getString("Name"));
                        }
                    } catch (Exception e) {
                        onError(e);
                    }
                }
            });
        }

        @Override
        public void onError(final Exception exception) {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    Toast.makeText(MainActivity.this,
                            MainActivity.this.getString(SalesforceSDKManager.getInstance().getSalesforceR().stringGenericError(), exception.toString()),
                            Toast.LENGTH_LONG).show();
                }
            });
        }
    });
}

EDIT 2 : Some more findings:

I think it has to do with my account/connected app settings. Because when I signedup using https://developer.salesforce.com/signup and used the username it works fine. Here again if I used the email instead it shows the same error of API not enabled. I created multiple usernames using the same email and the signup form, they all work fine, but not the email.

BTW I am currently using a trial version of salesforce.

Answer 1

regular trial accounts are for Professional Edition, which doesn't include API access, which is the error you're getting. You need to use an account with API access such as a free developer edition account, or an enterprise edition account.
