title: Neither user nor current process has android.permission.SERIAL_PORT
body: <p>I have gotten my hands on a Android POS device and I am currently trying to make our company's app work on the machine. a POS Z90 device.</p>
  <p>at one point I must the set the devName and baudRate (according to the example given)</p>
  <pre><code>handler.setParameters(&quot;/dev/ttyS2&quot;, 115200);
  </code></pre>
  <p>when i run:</p>
  <pre><code>handler.connect()
  </code></pre>
  <p>which calls:</p>
  <pre><code>this.mSerialPort = this.mSerialManager.openSerialPort(this.devName, this.baudrate);
  </code></pre>
  <p>I get the following android permission exception:</p>
  <blockquote>
  <p>Neither user (#number) nor current process has android.permission.SERIAL_PORT.</p>
  </blockquote>
  <p>So my question is how can i add the needed permission?</p>
  <p>background:</p>
  <blockquote>
  <p>minSdkVersion 19</p>
  <p>targetSdkVersion 25</p>
