これは、Google画像検索APIからの応答として取得しています。しかし、それを解析しようとすると、常に失敗して結果が得られません。
JSONObject json = new JSONObject(builder.toString());
final JSONArray geodata = json.getJSONArray("results");
final int n = geodata.length();
for (int i = 0; i < n; ++i) {
final JSONObject person = geodata.getJSONObject(i);
System.out.println(person.geString("width"));
}
私は何が間違っているのですか?
JSONObject json = new JSONObject(builder.toString());
//Add this line
JSONObject responseData = json.getJSONObject("responseData");
final JSONArray geodata = responseData.getJSONArray("results");
final int n = geodata.length();
for (int i = 0; i < n; ++i) {
final JSONObject person = geodata.getJSONObject(i);
System.out.println(person.geString("width"));
}
