title: Specify multiple permissions with android:permission on activity
body: <p>In my android application, I have an activity which specifies an intent filter. So, I want to protect it by specifying the android:permission attribute. I want to specify following four permissions:</p>
  
  <ul>
  <li>android.permission.INTERNET </li>
  <li>android.permission.ACCESS_NETWORK_STATE</li>
  <li>android.permission.READ_EXTERNAL_STORAGE</li>
  <li>android.permission.READ_LOGS</li>
  </ul>
  
  <p>But it seems, android:permission allows only one permission. How can I achieve this? I want the caller to have all these permissions before launching my activity.</p>
  
  <p>Thanks in advance.</p>
