title: Android service turns red
body: <p>I want to add a service to my manifest but it gives a warning in.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.aura_apps.tygo_asbroek.intentexample" &gt;
  
  &lt;application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:theme="@style/AppTheme" &gt;
      &lt;activity
          android:name=".MainActivity"
          android:label="@string/app_name" &gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
  
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
      &lt;activity
          android:name=".SecondActivity"
          android:label="@string/app_name" &gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
  
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  
      &lt;service
          android:name=".TygoIntentService"
      &gt;
      &lt;/service&gt;
  &lt;/application&gt;
  </code></pre>
  
  <p></p>
  
  <p>Here is the Java code: </p>
  
  <pre><code>package com.aura_apps.tygo_asbroek.intentexample;
  
  public class TygoIntentService extends IntentService {
  
      private static final String TAG = "com.bluelionapps.intentexample";
  
      public TygoIntentService(String name) {
          super("TygoIntentService");
      }
  
      @Override
      protected void onHandleIntent(Intent intent) {
          //This is what the service does
          Toast toast = Toast.makeText(getApplicationContext(), "Service Lauched", Toast.LENGTH_SHORT);
          toast.show();
      }
  }
  </code></pre>
  
  <p>Here you see my complete Manifest but <code>.TygoIntentService</code> says <code>TygoIntentService.java</code> doesn't have a default constructor of my app. If i run it, it's just working but I want to know if this can give any problems in the future and if it gives one what i need to do.</p>
