Android app with street view image API
<p>I used the street view image API in my android app,
and the following code is the way I retrieve images in my app :</p>

<hr>

<pre><code>URL url2 = new URL("http://maps.googleapis.com/maps/api/streetview?size=400x400" +                             "&amp;location="+x_str+","+y_str+"&amp;sensor=false"+"&amp;heading="+tmp_Azimuth+"&amp;key=xxxxxxxxxxx");

HttpGet httpRequest = new HttpGet(url2.toURI());
HttpClient httpClient = new DefaultHttpClient();
HttpResponse response = (HttpResponse) httpClient.execute(httpRequest);
HttpEntity entity = response.getEntity();
BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity); 
InputStream is = bufHttpEntity.getContent();
Bitmap bm = BitmapFactory.decodeStream(is);
iv.setImageBitmap(bm);
is.close();
</code></pre>

<hr>

<p>My app sends the above request every seconds,
and I usually get a error for "image return null" and get no images after few minutes,  but I am sure I didn't exceed the 25000 quota.
I checked the API console for the number of images I have requested, but it always shows the usage is 0 !!
Could anyone tell me which part of my usage get wrong so I got that error?  And why the API console did not show my usage?
I have been confused about this for a long time! 
Thank you very much for the help!</p>
