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 来获得BOOT_COMPLETED的使用许可,然后注册前面重构的IntentReceiver类,在其中加入 ,以使其能捕捉到这个Action。
- "android.permission.RECEIVE_BOOT_COMPLETED" />
- ".OlympicsReceiver" android:label="@string/app_name">
-
- "android.intent.action.BOOT_COMPLETED" />
- "android.intent.category.LAUNCHER" />
-
-
- public class OlympicsReceiver extends IntentReceiver
- {
-
- 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);
- 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)
- public class OlympicsReceiver extends BroadcastReceiver
- {
-
- 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);
- Toast.makeText(context, "OlympicsReminder service has started!", Toast.LENGTH_LONG)
- .show();
-
- }
- }
- }
