无法尝试使用HTTPGET检索Google API数据

Question

我正在尝试从Google Places API获取数据。但是，我的代码中的问题是我根本没有从HTTP客户端获取任何数据。

我在文本框中看不到什么都看不到（应该从Google API获得响应）

Java文件代码：

public class Httpexample extends Activity implements OnClickListener{
TextView tv_ResponseAPI;
Button btn_GetResponse;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.api_example);

    tv_ResponseAPI = (TextView) findViewById(R.id.tv_ResponseAPI);
    btn_GetResponse = (Button) findViewById(R.id.btn_GetResponse);
        btn_GetResponse.setOnClickListener(this);
    Log.v("Http", "entered the onCreate function");
}
@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    switch (v.getId()) {
    case R.id.btn_GetResponse:
        Log.v("Http", "Button was clicked");
        //tv_ResponseAPI.setText("Button was clicked");
        getInternetdata();          
        break;
    default:
        break;
    }
}
public void getInternetdata() {
    Log.v("Http", "Entered getInternetData()");
    try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpGet httpget = new HttpGet("https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=false&key=my_api_here");
        HttpResponse response = httpclient.execute(httpget);    
        HttpEntity entity = response.getEntity();
        InputStream webs = entity.getContent();
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(webs, "iso-8859-1"), 8);
            tv_ResponseAPI.setText(reader.readLine());
            webs.close();
        } catch(Exception e) {
            Log.e("log_tab", "Error Converting Result :" + e.toString());
        }
    } catch (Exception e) {
        Log.e("log_tab", "Error in http connection :" + e.toString());
    }       
}

}

即使我的API密钥（我已经检查过的）或某些东西搞砸了，我应该像以下内容一样得到JSON格式响应？我什么都没有。提出断点和调试，编程冻结并在"响应"语句之前什么都不做。

httpget（" ..."）中的URL是这里的示例：https：//developers.google.com/places/documentation/search

{
"html_attributions": [],
"results": [],
"status": "REQUEST_DENIED"
}

我能够使用asynctask解决问题。由于我的API级别> 3.0，我认为我需要使用它。

我在以下链接上遵循了代码示例，作为ping google ploces api的指南：http：//hmkcode.com/android-introid-intreid-internet-connection-usish-usis-http-get-httpclient/plient/plient/ptpclient/ptpclient/p>
