  <p>I've been searching for some answers and understood that the problem is from my manifest file. The problem is that <strong>I didn't touch my manifest for a long time (and it works today with the same manifest.</strong>
  Anyway, as I assume the manifest is important, this is my manifest:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="hhs.pack"
  android:versionCode="1"
  android:versionName="1.0" &gt;
  
  &lt;uses-sdk android:minSdkVersion="7" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  &lt;application
      android:icon="@drawable/ic_launcher"
      android:label="@string/app_name" &gt;
      &lt;activity
          android:name=".HhsActivity"
          android:label="@string/app_name"
          android:theme="@android:style/Theme.Black" &gt;
  
  
      &lt;/activity&gt;
      &lt;activity android:name="SimpleServiceActivity" 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=".Service.SimpleService"&gt;&lt;/service&gt;
  
     &lt;/application&gt;
  
  &lt;/manifest&gt;
