Service is not running background properly
<p>My service is working the problem is while is running it's showing  a black screen until the service finish.</p>

<pre><code>Intent Service = new Intent();
Service.setClass(Activity.this,sendInformation.class);
Service.putExtra("IP",IP1); 
Service.putExtra("Port",Port1);
Activity.this.startService(Service);
</code></pre>

<p>how i can say "while service is running" back to home?</p>
