为什么我的服务在 BOOT_COMPLETED 开始,但在 BATTERY_LOW 不开始?代码:
MyScheduleReceiver.java
public class MyScheduleReceiver extends BroadcastReceiver {
// Restart service every 30 min
private static final long REPEAT_TIME = 30*1000*4;//1800000 ;
@Override
public void onReceive(Context context, Intent intent) {
Intent service = new Intent(context, service.class);
context.startService(service);
}}
服务.java
public class service extends Service {
NotificationManager mNotificationManager;
@Override public IBinder onBind(Intent intent) {
// Not used
return null;
}
@Override public void onCreate() {
super.onCreate();
mNotificationManager= (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
checkPref();
}
@Override
public void onDestroy() {
super.onDestroy();
}
private void checkPref(){
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(
service.this);
notificationBuilder.setContentTitle("Title");
notificationBuilder.setContentText("Context");
notificationBuilder.setTicker("TickerText");
notificationBuilder.setWhen(System.currentTimeMillis());
notificationBuilder.setSmallIcon(R.drawable.ic_stat_icon);
Intent notificationIntent = new Intent(this, service.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
notificationIntent, 0);
notificationBuilder.setContentIntent(contentIntent);
notificationBuilder.setDefaults(Notification.DEFAULT_SOUND
| Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE);
mNotificationManager.notify(1,
notificationBuilder.build());
} }
并表现出来
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED">
<uses-permission android:name="android.permission.BATTERY_STATS">
<receiver android:name="MyScheduleReceiver" >
<intent-filter>
<action android:name="android.intent.action.BATTERY_LOW" />
</intent-filter>
</receiver>
<service android:name="service" >
</service>
那么我想要显示的电池电量不足的通知没有出现..如果我用 BOOT_COMPLETED 更改操作并且我重新启动设备工作..为什么?
