title: How to execute a file on /sdcard?
body: <p>I'm trying to run sqlite3 on my rooted Nexus 4. I've gotten as far as pushing the executable to /sdcard but I cannot execute it. I'm running stock Android 4.3, rooted with SuperSU 1.45.</p>
  
  <p>The file looks like this:</p>
  
  <pre><code>-rw-rw-r-- root     sdcard_rw    36860 2013-09-30 17:29 sqlite3
  </code></pre>
  
  <p>So far:</p>
  
  <ul>
  <li><code>chmod 777 sqlite3</code> does nothing</li>
  <li><code>File.setExecutable()</code> returns false (but <code>File.exists()</code> returns true).</li>
  </ul>
  
  <p>Is there a better way to do this?</p>
