我在解析表示FATAL EXCEPTION: main ava.lang.RuntimeException: Unable to instantiate application android.app.Application: java.lang.NullPointerException的JSON字符串时收到错误，但我不确定原因。我已经检查了响应，以确保它包含我正在寻找的字段 - 所以我不确定到底出了什么问题。
P.S。
我还在日志中进一步说明了另一个错误：

问题出在这里：
GetYouTubeUserCommentsTask task = new GetYouTubeUserCommentsTask(null, viewCount);
第一个参数不应该为空。
Handler handler = new Handler(new Handler.Callback() {
@Override

}
});
GetYouTubeUserCommentsTask task = new GetYouTubeUserCommentsTask(handler , viewCount);
