title: What is in android.util.Log#println_native()?
body: <p><a href="https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/util/Log.java" rel="nofollow">Here</a> is the <code>android.util.Log</code> source code.</p>
  
  <p>At the very bottom (line 340), what is in the method:</p>
  
  <pre><code>public static native int println_native(int bufID,
          int priority, String tag, String msg);
  </code></pre>
  
  <hr>
  
  <p>i guess <code>println_native()</code> is more or less like its <code>println()</code>, just with an <code>int bufID</code> different.</p>
  
  <p>But even i got the codes of <code>println_native()</code>, i still lack <code>com.android.internal.os.RuntimeInit</code> (line 19, the <code>import</code>) to simulate <code>android.util.Log</code> in old Android version.</p>
