Hi Hao, Thank you for reaching out to Google Ads API support with your questions. The API returns results in JSON, and you can process it however you wish.
With that being said, I was able to modify the GetKeywordStats.java sample to print out the JSON of the stream with this modification: for (SearchGoogleAdsStreamResponse response : stream) { for (GoogleAdsRow googleAdsRow : response.getResultsList()) { System.out.println(googleAdsRow.getAllFields().toString()); } } For further assistance you may reach out to the Java Client Library Issue Tracker. Here are listed the limitations on SearchStream. Reminder: Share your feedback about the Google Ads (AdWords) API!
