谷歌图书API 403访问未配置

我试图联系谷歌图书API和执行一个标题搜索，这仅需要一个公共的API密钥和没有的oauth2。我得到的是以下错误：

I'm trying to contact the Google Books API and perform a title search, which only requires a public API key and no OAUTH2. All I get is the following error:

{
    "error": {
        "errors": [
        {
            "domain": "usageLimits",
            "reason": "accessNotConfigured",
            "message": "Access Not Configured"
        }
        ],
        "code": 403,
        "message": "Access Not Configured"
    }
}

有一派周围小时后，似乎很多人有同样的问题，但与其他谷歌的API。什么我迄今所做的：

After having googled around for hours, it seems many others have the same problem but with other Google APIs. What I've done so far:

1. 在我注册开发项目控制台


2. 已启用的书籍API


3. 签名我的应用程序，以获得SHA1证书编号


4. 偏偏下载适用于Android的公开API密钥在我的开发者控制台


5. 粘贴下面的字符串到公共API密钥的形式，为了拿到钥匙：SHA1号; com.package，不带引号


6. 复制粘贴生成的密钥到我的code。

在code如下所示：

private void callGoogleBooks(){
    String key = MY_KEY;
    String query = "https://www.googleapis.com/books/v1/volumes?q=flowers+inauthor:keyes&key=" + key;
    Log.d("google books", callApi(query));
}

public String callApi(String query){
    HttpClient httpClient = new DefaultHttpClient();
    HttpGet getRequest = new HttpGet(query);
    HttpResponse httpResponse = null;

    try{
        httpResponse = httpClient.execute(getRequest);
    } catch(UnsupportedEncodingException e){
        Log.d("ERROR", e.getMessage());
    } catch(ClientProtocolException e){
        Log.d("ERROR", e.getMessage());
    } catch (IOException e){
        Log.d("ERROR", e.getMessage());
    }

    if(httpResponse != null){
        try{
            HttpEntity httpEntity = httpResponse.getEntity();
            InputStream is = httpEntity.getContent();
            BufferedReader br = new BufferedReader(
                    new InputStreamReader(is, "utf-8"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while((line = br.readLine()) != null){
                sb.append(line + "\n");
            }
            is.close();
            String responseString = sb.toString();
            return responseString;
        } catch (Exception e){
            Log.d("ERROR", e.getMessage());
        }
    }
    return null;
}

• 是否有任何明显的错误？我需要格式化或不同的包装我的要求？


• 请我需要添加任何东西的清单文件？


• 当指定程序包生成公共API密钥的时候，我需要指定相同的包名称作为我的应用程序结构？我读的地方，它必须是唯一的，但将其更改为不太可能是一个重复导致同样的错误的东西。



错误显然有usageLimits做的，但我不是，甚至接近每日允许的在我的测试项目中的1000呼叫的1％。

The error apparently has to do with "usageLimits", but I'm not even close to 1% of the 1000 calls allowed per day in my test project.

我也尝试实施不使用上述code，得到同样的错误消息，谷歌图书Java示例。我也尝试禁用和重新启用的书籍API，没有任何运气。

I've also tried to implement the Google Books Java Sample without using the code above, getting the same error message. I've also tried disabling and re-enabling the Books API, without any luck.

先谢谢了。
