问题描述
我有一个应用程序可以从 Google Books API 读取一些数据。
我使用 AsyncHttpRequest 来获取数据。
我开始收到以下错误：

我不确定是什么原因造成的，因为我读到使用 ExponentialBackOff 可能会有所帮助。
我的 AsyncHttpClient 正在使用具有以下功能的 loopj 库：
BackoffManager b = new BackoffManager() {
@Override
public void backOff(HttpRoute route) {
}
@Override
public void probe(HttpRoute route) {
}
}
但我不知道如何在课堂上使用它：
public void getBooks(final String query,JsonHttpResponseHandler handler) {
try {
client.get( API_BASE_URL + URLEncoder.encode( query,"utf-8" ),handler );
} catch (UnsupportedEncodingException ignored) {
}
}
对于如何在我的案例中实施此策略有任何建议吗？
谢谢
