title: why the android log cant be shown by the tag “CDMA” and “GSM”
body: <p>I'm trying to make use of logcat to println something.</p>
  
  <p>The code is as following:</p>
  
  <pre><code>String tag="CDMA".
  
  log.D("tag","blablabla")
  </code></pre>
  
  <p>but the output will be nothing....
  and if I change "CDMA" to "aaa", it can be shown. Is there anybody can explain it?
  Thanks...</p>
