Also register your created service in the Manifest and uses-permission as

<pre><code>&lt;application ...&gt;
 &lt;service android:name=".MyBroadcastReceiver"&gt;
 &lt;intent-filter&gt;
 &lt;action android:name="com.example.MyBroadcastReciver"/&gt;

and then in braod cast Reciever call your service

<pre><code>public class MyBroadcastReceiver extends BroadcastReceiver 
{
 @Override
 public void onReceive(Context context, Intent intent)
 {
 Intent myIntent = new Intent(context, MyService.class);

First register a receiver in your manifest.xml file:

<pre><code> &lt;receiver android:name="com.mileagelog.service.Broadcast_PowerUp" &gt;
 &lt;intent-filter&gt;
 &lt;action android:name="android.intent.action.ACTION_POWER_CONNECTED" /&gt;
 &lt;action android:name="android.intent.action.ACTION_POWER_DISCONNECTED" /&gt;
 &lt;/intent-filter&gt;
 &lt;/receiver&gt;
</code></pre>

and then write a broadcast for this receiver like:

<pre><code>public class Broadcast_PowerUp extends BroadcastReceiver {

 @Override
 public void onReceive(Context context, Intent intent) {
 String action = intent.getAction();

 if (action.equals(Intent.ACTION_POWER_CONNECTED)) {
 Toast.makeText(context, "Service_PowerUp Started",
 Toast.LENGTH_LONG).show();


 } else if (action.equals(Intent.ACTION_POWER_DISCONNECTED)) {



 Toast.makeText(context, "Service_PowerUp Stoped", Toast.LENGTH_LONG)
 .show();
 }
 }
}
</code></pre>

you should register for BOOT_COMPLETE as well as REBOOT

<pre><code>&lt;receiver android:name=".Services.BootComplete"&gt;
 &lt;intent-filter&gt;
 &lt;action android:name="android.intent.action.BOOT_COMPLETED"/&gt;
 &lt;action android:name="android.intent.action.REBOOT"/&gt;
 &lt;/intent-filter&gt;
 &lt;/receiver&gt; 
</code></pre>

I need to start a service at boot time. I searched a lot. They are talking about Broadcastreceiver. As I am new to android development, I didn't get a clear picture about services on Android. Please provide some source code.

我需要在启动时启动一个服务。我找了很多。他们在谈论广播接收器。由于我是Android开发的新手，我对android上的服务没有一个清晰的了解。请提供一些源代码。
