title: android: NeighboringCellInfo always empty !? why?
body: <p>i'm trying to get info about the neighboring cells my phone can "see" atm. so far so good. i do this like this:</p>
  
  <pre><code>telManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
  //...
  ArrayList&lt;NeighboringCellInfo&gt; neighboringCellList = (ArrayList&lt;NeighboringCellInfo&gt;) telManager.getNeighboringCellInfo();
  </code></pre>
  
  <p>unfortunately, this list turns out to be empty all the time. even in different places. i live in berlin, so i don't think it's because there is actually just the one cell available!</p>
  
  <p>update:
  my permissions look like this:</p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  &lt;uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_COARSE_UPDATES" /&gt;
  &lt;uses-permission android:name="android.permission.READ_PHONE_STATE" /&gt;
  </code></pre>
