1.开机启动后系统会发射出一个Standard Broadcast Action,名字叫Android.intent.action.BOOT_COMPLETED。
2.构造一个IntentReceiver类,重构其抽象方法onReceive(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。
an example:
AndroidManifest.xml:
1. <receiver android:name=".ServiceBroadcastReceiver" >
2. <intent-filter>
3. <action android:name="android.intent.action.BOOT_COMPLETED"/>
4. </intent-filter>
5. </receiver>
6. "android.permission.RECEIVE_BOOT_COMPLETED">
7. //获得RECEIVE_BOOT_COMPLETED使用许可
Java代码:
1. public class ServiceBroadcastReceiver extends BroadcastReceiver {
2. @Override
3. public void onReceive(Context arg0, Intent arg1) {
4. // TODO Auto-generated method stub
5. String action = arg1.getAction();
6. /*判断是否与action匹配*/
7. if(action.equals("android.intent.action.BOOT_COMPLETED"))
8. {
9. Intent serviceLauncher = new Intent(arg0, Service.class);
10. arg0.startService(serviceLauncher);
11. Log.i("ServiceBroadcastReceiver", "StockService loaded at start");
12. }
13. }
14. }
