Android(安卓)让一个Service开机自动启动

http://www.coderanch.com/t/439875/Android/Mobile/make-your-application-run-as

1.首先开机启动后系统会发出一个Standard Broadcast Action，名字叫android.intent.action.BOOT_COMPLETED，这个Action只会发出一次。

2.构造一个IntentReceiver类，重构其抽象方法onReceiveIntent(Context context, Intent intent)，在其中启动你想要启动的Service。

3.在AndroidManifest.xml中，首先加入<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>来获得BOOT_COMPLETED的使用许可，然后注册前面重构的IntentReceiver类，在其<intent-filter>中加入<action android:name="android.intent.action.BOOT_COMPLETED" /> ，以使其能捕捉到这个Action。

一个例子
xml：

Java代码

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
<receiver android:name=".OlympicsReceiver" android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</receiver>

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission><receiver android:name=".OlympicsReceiver" android:label="@string/app_name">     <intent-filter>        <action android:name="android.intent.action.BOOT_COMPLETED" />        <category android:name="android.intent.category.LAUNCHER" />     </intent-filter> </receiver>

Java代码

public class OlympicsReceiverextends IntentReceiver
{
/*要接收的intent源*/
static final String ACTION ="android.intent.action.BOOT_COMPLETED";
public void onReceiveIntent(Context context, Intent intent)
{
if (intent.getAction().equals(ACTION))
{
context.startService(new Intent(context,
OlympicsService.class),null);//启动倒计时服务
Toast.makeText(context, "OlympicsReminder service has started!", Toast.LENGTH_LONG).show();
}
}
}

public class OlympicsReceiver extends IntentReceiver {    /*要接收的intent源*/    static final String ACTION = "android.intent.action.BOOT_COMPLETED";            public void onReceiveIntent(Context context, Intent intent)     {        if (intent.getAction().equals(ACTION))         {                  context.startService(new Intent(context,                        OlympicsService.class), null);//启动倒计时服务             Toast.makeText(context, "OlympicsReminder service has started!", Toast.LENGTH_LONG).show();        }    }}

注意：现在的IntentReceiver已经变为BroadcastReceiver，OnReceiveIntent为onReceive。所以java这边的代码为：

（也可以实现应用程序开机自动启动） Java代码

public class OlympicsReceiverextends BroadcastReceiver
{
/*要接收的intent源*/
static final String ACTION ="android.intent.action.BOOT_COMPLETED";
public void onReceive(Context context, Intent intent)
{
if (intent.getAction().equals(ACTION))
{
context.startService(new Intent(context,
OlympicsService.class),null);//启动倒计时服务
Toast.makeText(context, "OlympicsReminder service has started!", Toast.LENGTH_LONG).show();
//这边可以添加开机自动启动的应用程序代码
}
}
}

public class OlympicsReceiver extends BroadcastReceiver{    /*要接收的intent源*/    static final String ACTION = "android.intent.action.BOOT_COMPLETED";            public void onReceive(Context context, Intent intent)     {        if (intent.getAction().equals(ACTION))         {                  context.startService(new Intent(context,                        OlympicsService.class), null);//启动倒计时服务             Toast.makeText(context, "OlympicsReminder service has started!", Toast.LENGTH_LONG).show();            //这边可以添加开机自动启动的应用程序代码        }    }}
