android - What Huawei AdsKit AdListener.onAdFailed errorCode 2 means?

Question

I have integrated Huawei AdsKit (banner ads) and registered AdListener. onAdFailed is called with errorCode = 2. What can be a reason?

There is something [strange] in the log (JSON error):

Answer 1

It seems to be an SDK bug: if AdParam.Bulder keywords are used it requires some other fields too.

I've compared my code with example and found the difference, i've passed ad request keywords:

private AdParam requestAd(boolean addKeywords) {
        AdParam.Builder builder = new AdParam.Builder();
        // --- cut start ---
        if (addKeywords) {
            String[] keywords = context.getResources().getStringArray(R.array.ad_keywords);
            for (String eachKeyword : keywords) {
                builder.addKeyword(eachKeyword);
            }
        }
        // --- cut stop ---
        return builder.build();
    }

If i specify the sex (builder.setGender(1);) - it does not help.

Don't set keywords to workaround it.
