  <h2 id="viewingStd">Viewing stdout and stderr</h2>

  <p>By default, the Android system sends <code>stdout</code> and <code>stderr</code>

  (<code>System.out</code> and <code>System.err</code>) output to <code>/dev/null</code>. In

  processes that run the Dalvik VM, you can have the system write a copy of the output to the log

  file. In this case, the system writes the messages to the log using the log tags

  <code>stdout</code> and <code>stderr</code>, both with priority <code>I</code>.</p>

  <p>To route the output in this way, you stop a running emulator/device instance and then use the

  shell command <code>setprop</code> to enable the redirection of output. Here's how you do it:</p>

  <pre>

$ adb shell stop

$ adb shell setprop log.redirect-stdio true

$ adb shell start

</pre>

  <p>The system retains this setting until you terminate the emulator/device instance. To use the

  setting as a default on the emulator/device instance, you can add an entry to

  <code>/data/local.prop</code> on the device.</p>

  output to <code>/dev/null</code>. (The Java <code>System.out</code> and <code>System.err</code>

  streams go to the log.)
